绥阳辣椒绿色轻简化高效生产技术应用评价及展望OA

Suiyang County is a major producing area of high-quality pepper in Guizhou Province and the core pepper-planting region in northern Guizhou.Conventional pepper cultivation is confronted with prominent constraints including high production costs,unstable yield and continuous cropping obstacles.To improve the economic benefits of pepper production,relying on the"Open Competition for Research Projects"mechanism and innovation and entrepreneurship initiatives,this paper systematically summarizes the green and simplified production technologies for Suiyang pepper based on practical experience and field application results of agricultural technicians.The technological system centers on intensive seedling raising,mechanized ridging and film mulching,hole punching and transplanting,precise water and fertilizer management,and green prevention and control of pests and diseases.Compared with traditional cultivation modes,this technological system reduces labor and agricultural material inputs,raises pepper yield,cuts the application rates of chemical fertilizers and pesticides,lowers the risk of agricultural non-point source pollution,improves farmland ecological conditions,and facilitates the sustainable development of the pepper industry.Currently,these technologies have been popularized across an area of 4 666.7 hm2(70 000 mu)in the county.The net income increases by 431.3 yuan per 667 m2.
