甜椒种植中,一些菜农对病虫害的认识不足和不合理的种植方式,使得病虫害发生较重。长期采用不合理的植保防治技术,使得生态环境日趋恶化,病虫害大暴发的可能性增大。生物多样性防控甜椒病虫害技术,即采用甜椒与玉米、花生、朝天椒等作物间作,引用新型栽培模式(起垄栽培),达到优质、高产、无公害生产的目的。生物多样性防控甜椒病虫害技术原理:通过间作改变了亲和寄主的空间分布,致使病害的传播和侵染受到影响(稀释效应);不同作物在生长和成熟时期植株高度上的差异,形成间作田块中高低起伏的表面不利于病害发生(阻挡效应);间作土壤中有益微生物和原生动物
In the cultivation of sweet pepper, some vegetable farmers have inadequate understanding of pests and diseases and irrational planting methods, which make the occurrence of pests and diseases heavier. Long-term use of unreasonable plant protection technology, making the deterioration of the ecological environment, pests and diseases increase the possibility of a big outbreak. Biodiversity pest prevention and control technology, namely the use of sweet pepper and corn, peanut, Asparagus and other crops intercropping, citing new cultivation mode (Ridge cultivation), to achieve high-quality, high yield, pollution-free production purposes. Biodiversity Control Pepper pests and diseases Technical rationale: The spatial distribution of the affinity host has been changed by intercropping, which affects the spread and infestation of the disease (dilution effect); differences in plant height between different crops during growth and maturity, resulting in Intercropping fields in the ups and downs of the surface is not conducive to disease occurrence (blocking effect); intercropping soil beneficial microorganisms and protozoa
