稻田综合种养模式对水稻病虫草害的控制作用及机理

现代农业中化学农药的使用大大提高了农业生产力,但同时也带来了环境等方面的负面影响。稻田综合种养是实现水稻农药减量、绿色高效生产的有效途径。本文论述了主要稻田综合种养模式对水稻病、虫、草害的控制作用和机理,以及由此而带来的农药减量效应,并针对浙江省实际情况,提出应加强种养技术的研究与应用,推动农业生产的可持续发展。

Controlling effects and mechanisms on rice diseases,pests and weeds in rice-based coculture system

Although the application of chemical pesticides has greatly increased agricultural productivity in modern agriculture, it has also brought about environmental and other negative effects. The rice-based coculture system was demonstrated as a successful approach to rice pesticide reduction and green, efficient productive way. This paper discussed the controlling effects and mechanisms of representative rice-based coculture system on rice diseases, pests and weeds, and its effect on pesticide reduction. It is suggested that further studies should be strengthened on technology packages for culturing rice and fish to achieve sustainable development of agriculture in Zhejiang Province.
