    Taking tomato continuous cropping obstacle soil as the research subject,this study employed High Performance Liquid Chromatography(HPLC)to identify the main phenolic acids present in the soil .Biological tests and growth curve measurements were conducted to reveal the effects of phenolic acids on tomato seed germination,seedling growth,and soil-borne pathogens.The results demonstrated that p-coumaric acid and p-hydroxybenzoic acid were the two predominant phenolic acids in tomato continuous cropping soil.Compared to seed germination,these two phenolic acids exhibited more significant autotoxic effects on tomato seedling growth.Under stress conditions of 100 mg · L-1 p-coumaric acid and 300 mg · L-1 p-hydroxybenzoic acid,the allelopathy index of tomato seedlings both reached -1.00.Under stress concentrations of 50 mg · L-1 p-coumaric acid and 100 mg · L-1 p-hydroxybenzoic acid,the relative chlorophyll content and photosynthetic parameters of tomato seedlings,including net photosynthetic rate,intercellular CO2 concentration, stomatal conductance,and transpiration rate,were significantly reduced compared with no phenolic pcids.Furthermore,within the concentration range of 200 mg·L-1,both phenolic acids promoted the growth of the soil-borne pathogen Fusarium oxysporum f. sp. Lycopersici race 8.In conclusion,p-hydroxybenzoic acid and p-coumaric acid in tomato continuous cropping soil impact tomato growth through dual mechanisms:directly inhibiting seedling development and stimulating the proliferation of soil-borne pathogens.

    Abstract:In 2024,the general market prices of vegetables predominantly adhered to the typical pattern of annual seasonal fluctuations.Nevertheless,during the summer-autumn periods,the prices tended to operate at relatively elevated levels.Owing to the impact of unfavorable weather conditions and their sustained eff ects,it is anticipated that the upward trajectory of vegetable prices in the current winter and the forthcoming spring will be less steep compared to previous years,with a potentially longer duration of the price-increasing cycle.Taking into account the fact that the overall vegetable prices were on the higher side in 2024 and the acreage under cultivation has increased year-on-year,it is projected that the overall supply of vegetables in the spring of 2025 will be ensured.

    Abstract:To address low water and fertilizer use effi ciency and soil secondary salinization from excessive irrigation and fertilization in facility vegetable production,we tested pepper variety‘ Xinrui’ using intelligent, precise drip irrigation and fertilization technology based on in-situ soil moisture monitoring. We implemented four treatments:traditional drip irrigation + traditional fertilizer(WhFh),high-frequency drip irrigation + traditional fertilizer(WlFh),traditional drip irrigation + optimized fertilizer(WhFl),and high-frequency drip irrigation + optimized fertilizer(WlFl).We examined the eff ects of these treatments on yield,growth indices,water and fertilizer use effi ciency,soil mineral nitrogen,and salt accumulation.Results showed that WlFl treatment reduced irrigation and fertilizer application by 29.9% and 50.0%,respectively,compared to WhFh,with no impact on pepper yield.However,leaf area increased by 63.6%,and the dry mass of roots,stems,and leaves rose by 29.5%,29.7%,and 24.0%,respectively.Additionally,N,P2O5,and K?O recovery in WlFl increased by 50.9,27.2,and 46.2 percentage points compared to WhFh.High-frequency drip irrigation reduced water loss by 44.7% to 66.4% and increased water utilization by 14.5-15.9 percentage points compared to traditional drip irrigation.Optimized fertilization treatments reduced soil surface watersoluble salt content by 21.4% to 34.7% and soil mineral nitrogen accumulation by 55.1% to 70.0% compared to traditional fertilization.In summary,high-frequency drip irrigation combined with optimized fertilization signifi cantly reduced water and fertilizer inputs and seepage losses,improved water and fertilizer utilization,and reduced soil mineral nitrogen and water-soluble salt accumulation,contributing to the green and sustainable production of facility vegetables.

    To clear and definite the resistance level of Tuta absoluta in the cities of Beijing and Zhangjiakou,the current work used leaf-dipping method with ten field-collected populations from the two cities to determine the levels of resistance to three popular diamide insecticides(5% chlorantraniliprole SC,20% fl ubendiamide WG,and 10% cyantraniliprole OD).The results displayed that most of the ten fi eld-collected populations have developed low level of resistance to chlorantraniliprole and flubendiamide,respectively,and some of them have developed moderate resistance to the two insecticides.On the other hand,most of the ten field-collected populations showed high susceptibility or decreased susceptibility to cyantraniliprole,and some of them displayed low level of resistance to it.Moreover,significant resistance to all of the three popular diamide insecticides were detected in the Zhangjiakou Huailai field-collected population.Based on previously published cases and results of this study,application of chlorantraniliprole and fl ubendiamide should be cautious due to the detection of moderate resistance.Although high susceptibilities of cyantraniliprole were observed in the most field-collected populations of T.absoluta,other classes of insecticides were recommended to rotation with the diamide insecticides to avoid potential resistance development resulting from similar mode of action.
