| 摘 要： | 1990至1994年间,在调查农民的综防知识、行为和分析主要稻区水稻病虫综合防治现状的基础上,研究了稻田节肢动物群落的结构和时间、空间格局,表明中性昆虫在水稻生长前期害虫一天敌营养链中起着重要的调控作用,测定水稻公蘖期具有较强的补偿效应,这为减少稻田用药寻求到一定的依据。提出了“栽后30天不用或少用农药”的害虫治理的简化实用模式,经三年在不同稻区的实践,取得了良好的效益。

| Abstract: | After investigated the knowledge of , attitude, and practice of IPM in Chinese farmers, and analyscd the main problems of IPM prachce in major rice regions in China, the dynamics of arthropod community was studied in three aspects-structure, time, and space respectively. The results show the "neutral insects" play an important role which links pests and natural enemy in the nutrition chains in the early stage of rice.Furthermore the compensation study of rice was applied and fund out there were strongly compensation effect in the tillering stage. Consequently, the simplify IPM model "Stopping or Reducing chemical application within 30 days after transplanting" was established. Aner evaluated this model for three years from 1990 to 1994 in different rice regions, the benefit was acquired in society and economics. |
