有机蔬菜生产中的病虫草害防治策略

Strategies of Pest, Disease and Weed Prevention in Organic Vegetable Production

在简述发展有机蔬菜的必要性和对环境的要求的基础上,介绍了有机蔬菜生产中病虫草害的防治策略和技术,主要包括合理的茬口安排,科学的施肥方法,灵活的农业措施,新型的生物和物理防治、天然的药剂采用以及有效的防除杂草技术等。在有机蔬菜生产中综合利用各种自然和生物的方法,利用蔬菜作物的生育规律,采用各种技术措施,提高蔬菜植株的抗病虫害能力,达到对病虫草害的预防和无害化防治的要求,实现生产优质有机蔬菜产品的目的。

For environmental safety, it is essential to produce organic vegetables. In this article, some strategies and techniques concerning pest, disease and weed prevention during vegetable production were presented. The studies include vegetable rotation, proper application of fertilizers, introducing the newly- developed biological and physical methods such as the application of natural pesticides, and the effective measurements of weed prevention. Combing these techniques with the regulation of growth and development of vegetables, the resistance of vegetables to pest, disease and weed would be improved, and the goal of production of high-quality organic vegetables would be reached.
