Analysis on the development of green fertilizer industry in Hanzhong
Green fertilizers play a crucial role in enhancing soil quality and the ecological environment of cultivated land.This paper employs field investigations,literature reviews,and data analysis to examine the current status of the green fertilizer industry in the Hanzhong region of Shaanxi Province,identify key challenges,and propose strategic recommendations for its development.In 2023,the planting area for green fertilizers in this region reached 11.06 hm2,primarily utilizing varieties such as Astragalus sinicus and Vicia villosa.The diversity of available varieties remains limited.Winter green manure is predominantly planted in rice fields,orchards,and tea gardens.However,the local green fertilizer seed breeding and production base is relatively small,leading to a heavy reliance on external seed supply,which has seen prices steadily increase.Green fertilizer cultivation contributes significantly to improving soil structure and nutrient content,thereby enhancing crop yields and quality,increasing grain production,and boosting farmers'income.Additionally,it reduces the application of chemical fertilizers and pesticides,mitigating agricultural non-point source pollution,thus offering substantial ecological and economic benefits.Despite these advantages,the green fertilizer industry in this region still faces several challenges,including a shortage of high-quality germplasm resources,low enthusiasm for green fertilizer planting,an incomplete technology system,immature industrial chain development,and incomplete support system for green fertilizer industry development,and insufficient guarantee and incentive effect.Based on this,the strategies were recommended such as strengthening germplasm resource management and seed industry support;enhancing diverse incentives to stimulate planting motivation;promoting the innovation of planting technology system and industry integration;and creating the industrial support system.The research provides a reference for promoting the development of green fertilizer industry in this area.
