稻田养鱼是当前农村开展多种经营,治穷致富的一条好门路。稻田养鱼不仅可以一田两用,提高经济效益,还可以提高土壤肥力,减少水稻病虫和杂草的发生,有利水稻增产。但是,也有一些人担心稻田养鱼会给病虫害的发生提供有利条件。针对这个问题,从1982年开始,我们选择了历年病虫害发生严重的门庄田、一般中肥高墈田以及边远的低肥田分别进行了养鱼与不养鱼的对比试验,定时、定点进行调查,分析比较稻田养鱼与不养鱼对水稻病虫、杂草的影响,得到了初步结果。
Fish farming in paddy fields is a good way to diversify and manage poverty in rural areas. Paddy field fish can not only be used in a field, improve economic efficiency, but also can improve soil fertility, reduce the occurrence of rice pests and weeds, favorable rice yield.

In response to this problem, from 1982 onwards, we have chosen a series of pests and diseases pest and disease over a long period of years Zhuang Tian, and in general fertile Gao Tian and remote low-fat fields were compared with fish and fish culture, regular, site-specific investigation, analysis and comparison The effect of paddy field fish farming and non-fish farming on pests and weeds in rice has obtained preliminary results.
