This study analyzed the current fertilization status and fertilization effects on major leafy vegetables in China based on literature. The rates of nitrogen，phosphorus，potassium recommendation and the fertilization effects including the relative yield，the yield increase，the yield increase rate，the yield response，and agronomic efficiency of nutrients were discussed. The limiting factors affecting leafy vegetable yield are mainly nitrogen，followed by potassium，and then phosphorus. Recommended fertilization in leafy vegetables reduced the amount of nitrogen and phosphorus fertilizer，increased the amount of potassium fertilizer，while increased the yield compared to conventional fertilization used by farmers. Therefore，suitable fertilizer recommendation method for leafy vegetables is an effective way to save fertilizer and improve efficiency.

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．

In order to analyze the production effi ciency of China’s pepper planting，the data envelopment analysis（DEA）method is employed based on survey data from the main pepper-planting provinces in 2022．The findings reveal generally low production efficiency in pepper planting across China，with significant regional diff erences．Variations are observed in optimal planting scale and production effi ciency among pepper planters and regions．Farmers in the northeastern region demonstrate the highest production effi ciency，while large-scale growers excel in the northwest．Cooperatives perform best in the Huang-Huai-Hai and centralsouthern regions，whereas leading enterprises show the highest efficiency in the eastern and southwestern regions．The research results indicate that the need to improve the production efficiency should target technological and management innovations according to regional characteristics and types of pepper planters．Additionally，providing policy support and technical training is essential to ensure optimal production effi ciency for each pepper planters．

Developing intelligent facility vegetables is an essential choice to achieve the goals of agricultural modernization and is crucial for ensuring a stable vegetable supply. Through macro analysis of the intelligent development of facility vegetables，reviewing its current status and revealing its significance in enhancing production effi ciency，improving agricultural product quality，and ensuring market supply，it was found that，espite the prominent performance of intelligent facility vegetables in increasing yield and improving quality，challenges such as high initial investment and maintenance costs，a mismatch between technology and human resources，and issues of data security and technological uncertainty limit their widespread application. Based on these challenges，this study proposes a series of strategies including growth-oriented，transformative，defensive，and diversified approaches，encompassing measures such as lowering entry barriers，promoting technological innovation，strengthening technology and human resource development，and enhancing data security and privacy protection. These strategies aim to provide scientific guidance and practical pathways for the sustainable development of intelligent facility vegetables.

A greenhouse study was conducted to promote mechanized vegetable production in solar greenhouses and explore suitable ridge distance for tomato cultivation on the east-west ridges．The study included tomato variety‘Ruiyilang’as a test material with traditional north-south ridge cultivation method as control（CK）and RD1（with middle ridge distance of 1.6 m），RD2（with middle ridge distance of 1.8 m），and RD3（with middle ridge distance of 2.0 m）3 treatments designed to east-west direction ridges to study the eff ects of diff erent ridge distances on canopy environment，plant growth and yield，and fruit quality of tomato in solar greenhouse conditions．The results showed that there was no signifi cant diff erence in plant height，stem thickness，stem and leaf fresh weight，and fruit quality among the three ridge spacing treatments of tomato in the east-west ridges when compared with CK；RD2 signifi cantly increased the light interception and average yield per plant by 11.22% and 11.17% compared to CK．Under RD2 conditions，the light interception per plant of the southern row was generally higher than that of the northern row and higher than CK．At the same time，the average yield per plant of the southern row increased by 6.30% to 21.46%，and the average yield per plant of the northern row increased by 4.06% to 10.93%．Furthermore，a work lane width of 1 meter between the RD2 ridges（work lane）is capable of meeting the specifi cations of a multifunctional work platform truck that has a width of 50-75 cm．Therefore，1.8 meters is an appropriate ridge distance parameter for mechanized tomato cultivation in the east-west ridges of a solar greenhouse．

Abstract：China is the largest producer and exporter of ginger in the world．She has diverse rangeof varieties and a basically stable production scale．By analyzing the international standing and domesticproduction and sales of ginger in China in recent years，we found that the advantages of old ginger productionarea were gradually losing，mechanization level of ginger production became low，and ginger market priceswere fluctuating obviously．Therefore，local governments of new and old production areas should formulatedifferent development directions，make their advantages prominent；accelerate research and development ofscience and technology，enhance mechanization level，reduce production cost；and build information servicesystem for ginger market，so as to improve market transparency．

In order to further enhance the anti-risk ability of ginger industry and increase rural household income，on the basis of studying China’s ginger planting input-output，this paper conducted comparative analysis on diff erent scale of operation，diff erent age of farmers，and planting cost and benefi t．At the same time，the paper also analyzed the factors aff ecting the cost and income fl uctuation of ginger planting．The results showed that the ginger price fl uctuation was one of the most important factors causing the instability of income. Besides，the instability of ginger yield also had greater impact on profi ts. The scale effi ciency of ginger was not signifi cant. Labor cost rose sharply along with the increase in scale，leading to a drop in profi ts．Judging from the cost point of view，the older farmers adopted management strategy of reducing investment and mitigating risk，which had become an obstacle to the high-quality development of ginger．On account of these，the paper suggested to develop ginger featured insurance，reducing management risk of farmer household；developing futures market，stabilizing ginger price；increasing investment in research and development of small machinery for ginger；and to improve the scale effi ciency of ginger industry through service scale．
