    Protected horticulture plays a crucial role in building a diversified food supply system and ensuring the security of agricultural product supply in China. Systematically reviewing the research progress in production regionalization is essential for optimizing industrial layout and reducing production costs. This study employed bibliometric analysis of literature using CiteSpace from 1998-2025 to identify research hotspots and trends through keyword co-occurrence and clustering. Additionally, an in-depth content analysis was conducted based on a six-dimensional framework covering influencing factors, affected entities, impact types, zoning scales, production scenarios, and factor indicators. The results indicate that current research predominantly focuses on climatic suitability and meteorological disaster risks, with temperature, solar radiation, and wind as core factors, while critical resource elements such as water, energy, and labor are largely overlooked. Studies are mainly conducted at provincial or regional scales, with national-scale zoning research being scarce and outdated. Production scenarios remain generalized, lacking refinement in matching specific facility types with suitable crops. Although diverse quantitative methods are applied, standardized indicator systems and integrated multi-factor coupling frameworks are underdeveloped. Consequently, existing zoning outcomes offer limited practical guidance for cost-effective and regionally adapted production planning. Future research should shift
    from a ‘climatic suitability’ paradigm toward a ‘production cost sensitivity’ approach, integrate climate-resourceeconomic
    multi-factor coupling, and advance from macro-scale zoning to refined, scenario-specific analyses to better support the high-quality development of protected horticulture in China.

    Construction of the whole industrial chain for specialty agriculture is a key pathway for improving agricultural quality and efficiency and increasing farmers’ income. Taking the aquatic vegetable industry in Baoying County, Jiangsu Province—a national typical county for whole industrial chain development—as the research object, this study adopts a longitudinal case study method to systematically examine the evolutionary trajectory of the aquatic vegetable industrial chain over more than 40 years and the organizational operation of its whole industrial chain. The findings show that the whole industrial chain of aquatic vegetables in Baoying has undergone three stages: resource endowment-driven development, processing and export-driven development, and organizational coordination-driven development. At present, Baoying has established benefit-linkage mechanisms such as contract farming, shareholding cooperation, and employee stock ownership; built public service platforms such as the ‘industrial chain + shared center’ model; and developed a quality inspection system covering the whole industrial chain, thereby achieving an organic connection between dispersed smallholders and standardized large markets. However, under the requirements of high-quality development, the industry still faces problems such as factor constraints, homogeneous product competition, and intensified market risks. Accordingly, this study proposes policy recommendations including innovating incentive and constraint mechanisms, building a multi-level strategic cooperation system, cultivating new quality productive forces, improving the efficiency of scientific and technological transformation, developing segmented
    markets, and constructing a diversified competitive landscape. These findings provide a reference for promoting the high-quality development of China’s specialty vegetable industry.

    To address the issues of insufficient innovation in characteristic celery varieties and uneven application of technologies in Shandong Province, a systematic investigation was conducted on planting scale, distribution patterns, cultivation methods, and pest and disease control. The results indicate that characteristic celery production zones with regional clustering have been established in Shandong. Greenhouse facility cultivation is the predominant method, with planting seasons covering spring, autumn, and winter, highlighting significant characteristics of industrial scale. Pest and disease control relies primarily on chemical agents, although partial integration of physical and biological control measures is also observed. Based on these findings, countermeasures and suggestions are proposed regarding germplasm resource conservation, technology application, industrial chain extension, and brand building, aiming to facilitate the high-quality development of the characteristic celery industry in Shandong Province.

    Since the nationwide suspension of pollution-free agricultural product certification and the vigorous promotion of green food certification, the production scale of green food in China has expanded rapidly. However, the supporting production technology extension system has not yet been established, resulting in a prominent mismatch between regulatory requirements and actual production practices. Based on the green food standard system, the relevant provisions for eggplant specified in GB 2763—2026, as well as pesticide registration data from the China Pesticide Information Network, this study constructed a five-dimensional progressive screening and analysis system consisting of ‘registration compliance-standard alignment-metabolite screening-residue limit verification-pre-harvest interval validation for green food’. Stepwise screening using this system reveals that, as of April 22, 2025, there are 209 registered pesticide products and 61 active ingredients available for use in eggplant in China, ultimately identifying 20 pesticides suitable for green food eggplant production. A comparison between NY/T 655—2020 and the standards of the EU and Japan shows that, of the 5 pesticides compliant with NY/T 393—2020, except for triadimefon whose maximum residue limit (MRL) is consistent with the EU standard, the residual limits of the other 4 pesticides are stricter than those of the EU and Japan, with some limits being up to 100-fold. The study also finds that the current system has insufficient pesticide residual limit settings, overly stringent standard requirements, imperfect production technical
    specifications, and poor coordination within the standard system. This study aims to provide a technical reference for the compliant selection and scientific application of pesticides in green food eggplant production, so as to promote the sustainable and healthy development of the green food industry.

    Okra (Abelmoschus esculentus L.) is an important vegetable crop with high nutritional and economic value, widely cultivated globally. However, its variety improvement has long relied on phenotypic selection and conventional experience-based breeding, which are plagued by long breeding cycles, low efficiency and insufficient precision. With the rapid advancement of genomic, modern biotechnology, and bioinformatics, molecular breeding technologies have provided a new approach to break through the bottlenecks in okra breeding. This review systematically summarizes the research progress in okra whole-genome sequencing and assembly, genetic dissection and functional gene mining of major breeding target traits (yield, quality, stress resistance, etc.), as well as the application of genetic engineering, marker-assisted selection (MAS) and other technologies in breeding practice. It aims to provide a reference for theoretical innovation and technological upgrading of okra molecular breeding, and promote its transformation from traditional breeding to a precise and efficient modern breeding mode.

    In order to construct a comprehensive quality evaluation system for large-fruited taste-oriented tomatoes, eight large-fruited tomato varieties (including one common tomato as control) from different sources were used as materials. Five methods, including sensory evaluation, correlation analysis, membership function method, principal component analysis (PCA), and cluster analysis, were systematically integrated to construct a comprehensive evaluation technical system integrating ‘determination-analysis-evaluation-classification’. Through the determination and analysis of 12 key quality indicators, the results showed that: Yutianyou 6 had the highest sensory score (8.10), and all flavor tomato varieties exhibited significantly better sensory and nutritional quality than the common tomato control. Correlation analysis revealed that soluble sugar content and sugar-to-acid ratio were extremely significantly positively correlated with volunteer taste scores (r = 0.787, 0.684). Principal component analysis extracted four principal component factors with a cumulative variance contribution rate of 90.22%, which were defined as flavor quality factor (PC1, 40.14%), taste-nutrition factor (PC2, 25.30%), storage-transport quality factor (PC3, 14.29%), and functional component factor (PC4, 10.49%). A comprehensive evaluation mathematical model was constructed：C = 0.4014B1 + 0.2530B2 + 0.1429B3 + 0.1050B4. Cluster analysis divided the varieties into three groups, and combined with the membership function method, three varieties with optimal comprehensive quality were screened out: Yuyi Suantian guo, Yutianyou 7, and Jingcai No. 6. The multi-dimensional quality evaluation system for large-fruited flavor tomatoes constructed in this study provides quantifiable and operable methodological support for variety breeding and standardized quality evaluation of large-fruited tomatoes.

    Black spot disease is a major fungal disease threatening Chinese cabbage production worldwide. To establish a reliable, reproducible, and efficient phenotyping system to evaluate seedling resistance to black spot disease caused by Alternaria brassicicola, we systematically optimized the inoculation conditions by comparing inoculation methods, spore suspension concentrations, and incubation temperatures. The results showed that detached-leaf inoculation performed on seedlings with a spore suspension of 1 × 105 spores · mL-1, followed by incubation at 25 ℃ for 3 days, provided the most effective and repeatable conditions for assessing black spot disease resistance. The optimized assay was further validated using 53 elite Chinese cabbage inbred lines, with parallel field disease assessments conducted at the adult plant stage. The high concordance between the two evaluation approaches verified the accuracy, stability, and reliability of the artificial inoculation system. Furthermore, germplasm lines representing the extremes of disease resistance were selected, providing valuable parental materials for identifying genes associated with black spot disease resistance. Together, these results provide both germplasm resources and a technical foundation to advance molecular breeding for enhanced black spot disease resistance in Chinese cabbage.

    WRKY transcription factors constitute one of the largest transcription factor families in plants and play pivotal roles in plant responses to abiotic stress. In this study, we performed bioinformatic analysis and expression patterns of two potato genes, StWRKY57 and StWRKY58, under abiotic stress conditions, and preliminarily characterized the function of StWRKY57 in potato drought stress response through genetic transformation. The results showed that the full-length ORF of StWRKY57 and StWRKY58 were 762 bp and 786 bp , respectively, each encoded a conserved WRKY domain. Expression analysis revealed that the transcript levels of StWRKY57 and StWRKY58 differed significantly among potato cultivars with contrasting drought tolerance. Both genes responded positively to ABA treatment, with StWRKY57 exhibiting a stronger response. Further expression analysis revealed that StWRKY57 was differentially expressed under various abiotic stresses. In addition, overexpression of StWRKY57 significantly increased the leaf water content in
    transgenic potato lines. These results demonstrate that StWRKY57 and StWRKY58 are typical members of the WRKY transcription factor family, and that StWRKY57 functions as a positive regulator of drought tolerance in potato. These findings provide candidate genes and a theoretical foundation for molecular breeding of stress tolerance in potato, and are of great significance for the stress-resistance biological breeding of this crop.

    The double haploid materials are very important for the breeding of new high-sulforaphane content broccoli varieties. This study assessed the agricultural traits of 94 broccoli germplasm resources, and analysed the sulforaphane content of 82 broccoli germplasm resources. Among 52 germplasm resources, which with normal flower buds were selected for microspore culture. The results showed that there were 65 high-sulforaphane-content germplasm, and 20 accessions were produced embryos successfully. BOP04-28-67 exhibited the highest embryo yield (14.03 embryos per bud), while BOP04-28-27 and BOP04-28-48 only yielded 0.02 embryos per bud. During embryo regeneration, the survival rate of cotyledon-shaped embryos reached 97.33%, higher than that of torpedo-shaped embryos significantly. The optimal formula for the solid culture medium was B5 + 20 g · L-1 sucrose + 8 g · L-1 agar．The optimal formula for the rooting medium for regenerated seedlings was MS + 20 g · L-1 sucrose + 0.1 mg · L-1 NAA + 10 g · L-1 agar. A total of 12 highsulforaphane-content broccoli germplasm resources embryos were obtained in this study, and 5 of them produced regenerated plants. Flow cytometry analysis results revealed that there was no pollen in the floral organs of
    haploid plants, which couldn’t seed setting, whereas diploid plants produced abundant pollen and had a high seed-setting rate, whilst polyploids produced pollen but had a low seed-setting rate. The experimental results provided an important reference for the efficient breeding of high-sulforaphane broccoli DH materials.

    Phosphorus is a core nutrient element for crop growth and development, participating extensively in key physiological processes such as biomolecular synthesis, energy metabolism, and photosynthesis. Given the high phosphorus demand of greenhouse vegetables and the widespread deficiency of available phosphorus in arable soils in China, the utilization of phosphate-solubilizing microorganisms to mineralize organic phosphorus and dissolve inorganic phosphorus has become a pivotal strategy for promoting green agricultural development. In this study, using plant growth performance under phosphorus-deficient conditions as the screening criterion, two efficient phosphate-solubilizing bacterial strains, Acinetobacter soli 290 and Enterobacter cloacae XL26, were successfully obtained. A systematic characterization of their physiological properties was subsequently conducted. The results demonstrated that both strains effectively solubilized inorganic phosphorus (with solubilization amounts of 350.84 and 334.62 mg · L-1, respectively) and organic phosphorus (with solubilization amounts of 111.40 and 143.84 mg · L-1, respectively) , and both reduced the
    pH of the culture medium through acid production during the solubilization process. Furthermore, the strains exhibited remarkable stress tolerance, maintaining normal growth under NaCl concentrations up to 9% and across a pH range of 5-10, thereby providing a guarantee for their agricultural application under diverse geographical conditions. Greenhouse soil experiments revealed that the application of bacterial agents prepared from the two selected strains significantly promoted various growth parameters of watermelon. Notably, the growthpromoting effects under phosphorus-free fertilization conditions were superior to those under normal phosphorus application. Under phosphorus-free conditions, the plant height of watermelon seedlings increased by 78.42% and 83.84%, respectively, while the dry weight increased by 150.30% and 188.47%, respectively. The phosphorus uptake efficiency of watermelon was enhanced by 138.59% and 223.67%, respectively. In addition, the bacterial agents effectively improved stem diameter, leaf area, and photosynthetic pigment content. Collectively, these findings indicate that the stress tolerance and growth-promoting potential of the selected strains primarily stem from their ability to convert insoluble phosphorus in soil, highlighting their promising value in phosphorusdeficient agricultural production.

    Using the Chinese cabbage cultivar ‘Xinwang’ as the test material, a field experiment was conducted under open-field autumn cultivation with four silicon fertilizer application rates: 0 kg · hm-2 (CK), 375 kg · hm-2 (T1), 562.5 kg · hm-2 (T2), and 750 kg · hm-2 (T3), to investigate the effects of different silicon fertilizer concentrations on the growth, yield, and quality of Chinese cabbage. The results showed that application of silicon fertilizer at various concentrations significantly increased plant height, gross plant weight, net plant weight, photosynthetic rate, soluble sugar content, soluble protein content, free amino acid content, and reduced ascorbic acid content to varying degrees. Among all treatments, the T3 treatment produced the highest net plant weight, which was 19.21% higher than CK with a significant difference. The T2 treatment ranked second and showed no significant difference from T3. Meanwhile, the T2 treatment had the highest soluble protein and free amino acid content, which were 32.90% and 31.85% higher than CK, respectively, with significant differences. In conclusion, the T3 treatment exhibited the best yield-increasing
    effect, whereas the T2 treatment effectively improved some quality indicators while maintaining a relatively high yield.

    Saline-alkali stressseriously affects the yield and quality of ginger. As soil salinization becomes increasingly prominent, the identification and evaluation of saline-alkaline tolerance in ginger germplasm resources are of great significance for exploring elite genes, breeding salt-alkaline tolerant varieties, and ensuring the safety of ginger production. To screen salt-alkaline tolerant ginger germplasm, we investigated 11 major agronomic traits of 60 ginger accessions and analyzed the variation characteristics of the plant salt injury index under saline-alkali stress. The results showed that there were significant differences in saline-alkaline tolerance among the tested ginger accessions. The plant salt injury index ranged from 0.167 to 0.690, with a coefficient of variation of 30.33%. Based on cluster analysis using the salt injury index, the 60 ginger accessions were classified into three groups: salt-alkaline tolerant type, sensitive type, and intermediate type. Among them, nine accessions were identified as salt-alkaline tolerant. The coefficient of variation of agronomic traits ranged from 8.65% to 45.20%. Correlation analysis showed that shoot fresh weight, leaf fresh weight, finger thickness, finger length, plant height, leaf width, and leaf length were extremely significantly positively correlated with rhizome fresh weight, whereas only leaf width and root fresh weight showed significant or extremely significant negative correlations with the salt injury index. Path analysis indicated that finger thickness and leaf fresh weight had relatively large direct effects on rhizome fresh weight, with path coefficients of 0.579 and 0.455, respectively, while leaf width had a relatively small direct effect on the salt injury index, with a path coefficient of -0.419. In summary, there was no significant correlation between saline-alkaline tolerance and agronomic traits in
    ginger. Therefore, further in-depth studies on the genetic background and physiological metabolism of saltalkaline
    tolerant germplasm are required for breeding salt-alkaline tolerant ginger varieties.

    To screen high-yield and high-quality chives varieties suitable for cultivation in Guizhou region, a randomized block design was adopted, with the locally cultivated variety ‘Fujiuhuang No.2’ as the control. The resistance (lodging resistance, rust resistance, gray mold resistance), morphological characteristics during the green stage, yield, and nutritional quality of 11 varieties were systematically compared, and a comprehensive evaluation was conducted. The results showed that ‘Jiuboshi’ and ‘Zhonghuashenjian’ had the best comprehensive resistance, exhibiting resistance to lodging and gray mold. Both varieties showed good growth vigor in the field, with thick leaves, sturdy pseudostems, and strong growth potential and adaptability. The yields of ‘Jiuboshi’, ‘Zhonghuashenjian’, ‘Jinhuangjinjiu’, and ‘Fusheng 2909’ were significantly higher than that of ‘Fujiuhuang No.2’ (CK), with an increase of more than 13%, among which ‘Jiuboshi’ had the highest yield increase, reaching 21.09%. ‘Fujiuhuang No.2’ had the highest content of calcium, zinc, total sulfur, crude fiber, and crude fat, ranking first in the comprehensive evaluation of nutritional quality. ‘Fusheng No.2’ and ‘Jiuboshi’ also had good comprehensive quality, while ‘Jinhuangjinjiu’ had relatively lower comprehensive
    quality. Considering all factors, ‘Jiuboshi’ can be widely promoted and applied as a high-yield and high-quality chive variety in open fields in Guizhou and similar regions, while ‘Fujiuhuang No.2’ should be promoted and applied as a high-quality chive variety.

    To systematically assess seedling-stage disease resistance of Chinese cabbage cultivars listed in the National Directory for the Promotion of Excellent Crop Varieties (2023), this study conducted seedlingstage resistance evaluations of nine core varieties and seven emerging lines of Chinese cabbage to soft rot, clubroot, and Verticillium wilt using detached-leaf inoculation, pathogen-suspension root drenching, and root-dip inoculation methods, respectively, under greenhouse conditions. The results showed that all tested Chinese cabbage varieties were susceptible or highly susceptible to soft rot. For clubroot resistance, isolates collected from Henan, Chongqing, and Hebei were used for inoculation. Variety ‘CR117’ exhibited resistance or high resistance to isolates from three regions, where as ‘Xixing 90’ and ‘Xixing 78’ showed resistance to isolates from Henan and Chongqing. In contrast, ‘Improved Qingza No.3’ , ‘Qinghua 76’ and ‘Autumn Green 60’ were found to be susceptible or highly susceptible to isolates from three regions. In Verticillium wilt assays, only ‘Jingqiu No.3’ displayed moderate resistance, while all other varieties exhibited susceptibility or high susceptibility. Collectively, these results demonstrate pronounced differences in resistance profiles between core and emerging Chinese cabbage varieties against three major diseases, offering valuable insights and a basis for disease-resistant Chinese cabbage breeding and region-specific cultivar deployment.

    Tomato Fusarium wilt is one of the most destructive diseases affecting tomato production. To screen for effective biocontrol bacteria against tomato Fusarium wilt, a bacterial strain designated MT1406 with strong antagonistic activity was isolated using Fusarium oxysporum f. sp. lycopersici as the target pathogen. Based on morphological characteristics, physiological and biochemical properties, and multilocus phylogenetic analysis, strain MT1406 was identified as Bacillus velezensis. Antagonistic spectrum analysis showed that MT1406 exhibited strong inhibitory activity against five fungal pathogens and one oomycete pathogen. Functional characterization demonstrated that the strain possessed nitrogen-fixing, phosphatesolubilizing, potassium-solubilizing, and protease-producing abilities. In addition, seven antimicrobial secondary metabolite biosynthetic genes, namely surfactin, macrolactin, fengycin, difficidin, bacillibactin, bacillaene, and iturin, were detected in the strain. Pot experiments showed that MT1406 provided a control efficacy of 67.78% against tomato Fusarium wilt. These results indicate that B. velezensis MT1406 has considerable potential for the biological control of tomato Fusarium wilt.

    To explore the application effect of winter supplementary lighting in protected pepper production, field plot experiments were conducted using low temperature and weak light tolerant and sensitive cultivars of Capsicum annuum (cv. screw pepper and line pepper). The effects of different LED light intensities and spectra on pepper yield and economic benefit were compared. The results showed that, compared with the non-supplementary control, all LED lighting treatments significantly increased total yield. Among them, the T1 treatment increased the yield of low temperature and weak light tolerant cultivars by more than 12.78%, while the yield increase of sensitive cultivars was more pronounced, reaching over 19.98%. Economic analysis indicated that, after accounting for lighting costs, the profit rate under T1 treatment was 6.33%-26.60% higher than that of the control. These findings demonstrate that appropriate LED supplementary lighting can effectively enhance winter pepper yield and economic efficiency in greenhouse production, providing a technical reference for efficient pepper cultivation under protected conditions.

    Soil salinization is a major constraint for agricultural sustainability. Therefore, it is of great significance to cultivate salt-tolerant crop varieties for enhancing the productivity of saline-alkali soils. In this study, eight pepper germplasms including ‘Sai 2’ ‘Sai 6’ ‘Sai 9’ ‘Sai 10’ ‘Long 10’ ‘Long 13’ ‘A6’ and ‘M3’ were subjected to salt stress by applying a 200 mmol · L-1 NaCl solution for 24 hours at the six-leaf stage. The salt tolerance of various genotypes in pepper was evaluated using 12 physiological indices, including content of malondialdehyde (MDA), relative electrolyte conductivity (REL), reactive oxygen species (O2-. and H2O2) levels, antioxidant enzyme (SOD, POD, CAT) activity, photosynthetic gas exchange parameters, and content of free proline (Pro). The results showed that the content of MDA and REL in the leaves of all tested materials increased after salt stress. Concurrently, the accumulation of O2-. and H2O2 rose, while the net photosynthetic rate, transpiration rate, and stomatal conductance declined. Additionally, the intercellular CO2 concentration increased, and content of Pro exhibited a significant rise. Notably, the degree of response varied significantly among different materials. Principal component analysis (PCA) revealed that the two principal components accounted for a cumulative variance of 81.61%. The salt tolerance of eight accessions in pepper was ranked in descending order as follows: ‘Sai 9’ ＞ ‘Sai 10’ ＞ ‘Long 13’ ＞ ‘Sai 2’ ＞ ‘Sai 6’ ＞ ‘Long 10’ ＞ ‘A6’ ＞ ‘M3’, based on their respective tolerance scores. In summary, ‘Sai 9’ and ‘Sai 10’ were selected as genotypes with strong salt tolerance. In contrast, ‘A6’ and ‘M3’ had the weakest salt tolerance.

    To explore the regulatory effects of polyamino acid foliar fertilizer on cucumber growth and screen its optimal field application concentration, pot experiments using cucumber seedlings and field cultivation trials were carried out with a series of dilution gradients of polyamino acid foliar fertilizer (600-fold, 800-fold, 1 000-fold, 1 200-fold and 1 500-fold dilutions). The results indicated that polyamino acid foliar fertilizer significantly promoted the vegetative growth (roots, stems and leaves) and biomass accumulation of cucumber seedlings in the pot experiment, and effectively enhanced root activity and leaf photosynthetic capacity. Among all tested treatments, the 1200-fold dilution treatment exerted the best regulatory effect, which produced the maximum seedling plant height, stem diameter, root length, root activity, fresh weight and dry weight at 22.88 cm, 4.03 mm, 25.36 cm, 1.23 mg · g-1 · h-1, 3.84 g and 0.21 g respectively. These four indexes were significantly increased by 38.4%, 44.4%, 49.7%, 68.5%, 23.5% and 50.0% compared with the clear water control (CK), respectively. Moreover, this treatment also obtained the highest leaf net photosynthetic rate, stomatal conductance and water use efficiency across all groups. In the field trial, foliar application of 1 200-fold diluted polyamino acid fertilizer significantly increased cucumber plant height and stem diameter. The single fruit weight and yield per plant reached 127.79 g and 1.52 kg, representing significant increments of 26.3% and 10.1% relative to the CK. In addition, internal fruit quality was greatly optimized. Compared with CK, contents of soluble sugar, vitamin C and crude protein increased significantly by 24.4%, 25.5% and 48.6%, while nitratenitrogen content declined significantly by 23.1%. In summary, foliar spraying polyamino acid foliar fertilizer at a 1 200-fold dilution can remarkably facilitate cucumber growth and development, and simultaneously improve fruit yield and nutritional quality.

    Bacterial fruit blotch of watermelon is an important seed-borne bacterial disease that severely affects cucurbit crops. A PMA-PCR method was developed for the specific detection of live cells of the bacterial fruit blotch pathogen of watermelon by combining propidium monoazide (PMA) with PCR technology. The results showed that when the PMA concentration was 10 μmol · L-1, followed by incubation in the dark for 10 min and exposure for 20 min, the amplification of DNA from dead bacteria could be effectively inhibited without affecting the detection of live bacteria. The minimum detection limit for live bacteria was 1 × 104 CFU · mL-1. The established PMA-PCR method was applied to detect watermelon, bottle gourd, and melon seeds, and the results demonstrated that it could quickly and stably distinguish between contaminated and sterilized seeds, accurately identifying the presence of live bacteria. This detection method provides reliable technical support for seed health testing and early control of bacterial fruit blotch of watermelon.

    To explore the potential application of ethanol extracts from Camellia oleifera cake in controlling Meloidogyne incognita, laboratory toxicity assays, egg hatching inhibition tests, mixture synergy experiments, and pot control efficacy trials were conducted. Focusing on the ethanol extract alone and its combination with fluopyram 41.7% suspension concentrate (SC), the nematicidal and inhibitory activities against M. incognita were systematically evaluated, and the synergistic effect of the combination as well as its pot control efficacy were analyzed. The ethanol extract exhibited significant nematicidal activity against M. incognita second-stage juveniles (J2s) , with the EC50 value decreasing over time and reaching 1.43 mg · mL-1 at 72 h. The extract also strongly inhibited egg hatching, showed an inhibition rate of 85.12% after 7 days at 15.0 mg · mL-1. Synergism analysis revealed that combinations of fluopyram and the ethanol extract at toxic unit (TU) ratios of 1∶1, 1∶3, 1∶5, 1∶9 and 3∶1, all combination index (CI) ＜ 1, and the synergy ratios (SR) were all greater than 1, indicating significant synergistic effects. In pot experiments, the 1∶5 mixture treatment achieved 85.41% efficacy in reducing rhizosphere J2s populations and 82.06% in reducing root gall, both obviously superior to single-agent treatments. In conclusion, the ethanol extract of C. oleifera cake exhibited strong biological activity against M. incognita and showed a synergistic effect with fluopyram. The combined application

    obviously enhanced control efficacy at appropriate ratios, providing a scientific and technical basis for the green management of root-knot nematodes in protected vegetable production using C. oleifera by-products.

    To investigate the impact of the deployment height and location of sex pheromone traps on the trapping effectiveness of the overwintering Tuta absoluta in protected cultivation, and to optimize their placement within the facilities to enhance control efficacy and the accuracy of monitoring and early warning, experiments were conducted using triangular sex pheromone traps in three overwintering tomato production greenhouses at Lianhu Farm in Ningxia. The results indicated that during the early growth stage of tomatoes, the optimal hanging height is 30 cm, while for the later stages, it should be set at 50 cm. Therefore, it is recommended that the placement of sex pheromone traps be adjusted according to the tomato growth stage. The activity of Tuta absoluta in the overwintering tomato facilities is primarily concentrated near the entrance and exit of the greenhouse front, where the trapping effectiveness of the traps is optimal. Additionally, the occurrence and damage caused by the larvae are also concentrated at the front of the greenhouse, with damage decreasing as one moves deeper into the greenhouse. The findings of this study provide a theoretical basis for the biological control of the overwintering Tuta absoluta in protected cultivation.
