稻田养鱼是把植物与动物共生、种植业和养殖业结合起来的一种新的农业生态系统,是调整农村产业结构,提高经济效益的有效途径之一。我县从1982年开始进行稻田养鱼试验示范工作,几年来由于对稻鱼共生规律的不断摸索,从而使放养面积逐年扩大,累计已达2500亩左右。同时效果也越来越显著,养鱼稻田平均亩收稻谷467.0公斤,比对照田块亩增4.0公斤;平均亩收鱼苗871尾.34.8公斤,价值65.6元。合计每亩收入252.40元,比对照田块亩增收67.20元,剔除增支部
Fish farming in paddy fields is a new agroecosystem that combines plant and animal symbiosis, crop farming and aquaculture. It is an effective way to adjust rural industrial structure and improve economic efficiency. Since 1982, the county has carried out experimental trials on paddy field fish culture. Over the past few years, due to continuous exploration of the symbiotic rules of rice and fish, the stocking area has been expanded year by year, reaching a total of 2,500 hectares. At the same time, the effect is also more and more obvious. The average harvest of rice in the fish-raising paddy fields is 467.0 kg, which is 4.0 kg more than that of the control plots. The average harvest is 871 fries, 34.8 kg and 65.6 yuan. Total income of 252.40 yuan per mu, compared with the control plots mu income 67.20 yuan, excluding by-branch
