利用冬闲稻田养鱼既可提高稻田的利用率,又可提高农民的经济收入,减少禾苗病虫害,减少来年的农药、化肥支出。另外春季种禾苗时可以免耕、节省人工,并可获得稻鱼双丰收。通过稻田工程改造、科学放养和管理,每667米~2可产商品鱼150～200千克,亩获纯利800元左右,投入产出之比为1:2,可取得良好的经济效益和生态效益。现将冬闲稻田养鱼技术作一介绍。
The use of winter-time paddy fish farming can not only improve the utilization rate of paddy fields, but also increase the economic income of farmers, reduce the amount of pests and diseases of pests and reduce the expenditure of pesticides and fertilizers in the coming year. In addition the spring seedlings can be no-tillage, save labor, and access to double-harvest rice. Through the paddy field engineering, scientific stocking and management, every 667 meters ~ 2 can produce 150 ~ 200 kilograms of fish, net profit of 800 yuan per mu, the input-output ratio of 1: 2, can achieve good economic and ecological benefits . Winter paddy rice farming technology now make an introduction.
