Study on the Contribution Rate of Pepper Plant Protection in Chongqing Conventional Vegetable-Planting Areas
-
摘要: 辣椒作为我国重要经济作物,其病虫害防治极其重要.由于受目前农业面源污染严重、农业化学品施用不当等因素影响,辣椒病虫害暴发严重.结合全国各地的辣椒病虫害防治调查结果,发现我国辣椒植保贡献率存在被低估的问题.本研究通过试验明确了在进行科学的防治后,与常规防治相比,辣椒病虫害发生率降低了9.90%~24.24%,产量提升11.76%,植保贡献率为36.77%.本研究对我国辣椒植保贡献率进行科学评价,以期为我国辣椒病虫害防治提供科学依据.Abstract: Pest control of hot pepper, an important cash crop in China, is of great significance. Due to the serious agricultural non-point source pollution and improper application of agricultural chemicals, the outbreak of pepper diseases and pests is serious in the country. In order to provide a scientific basis for pepper pest control, this paper makes a scientific evaluation of the contribution rate of pepper plant protection in China. Based on the survey results of pepper disease and pest control all over the country, it is found that the contribution rate of pepper plant protection in China is underestimated. It is found through experiments that compared with conventional control practice, the measures of scientific control reduce the incidence of pepper diseases and pests by 9.90%-24.24% and increase yield by 11.76%, and that the contribution rate of plant protection is 36.77%.
