稻田养鱼把种植业与养殖业紧密结合起来,不仅能解决吃鱼难,而且能提高经济效益。但是,稻田养鱼会因水稻搁田和喷药治虫而影响鱼的生长。近年来,我们通过试验证明稻田养鱼只要掌握以下三个环节,可以获得稻鱼双丰收。 一、挖鱼沟鱼窝 稻田养鱼要保持足够水层,但是与水稻栽培的促控措施有矛盾,长期灌深水易造成水稻旺长,加重倒伏和病虫危害。同时,防治水稻病虫时全田保持水层,鱼苗散布全田中,增加受
Paddy fish farming and farming industry closely integrated, not only can solve the difficulty of eating fish, but also improve economic efficiency. However, fish farming in paddy fields can affect the growth of fish due to rice fields and spraying pests. In recent years, we have proved through experiments that as long as the following three aspects of fish farming in paddy fields can be achieved double-harvest rice. First, digging fish ditch fishpond paddy field fish to maintain adequate water layer, but with the rice cultivation control measures are contradictory, long-term irrigation deep water easily lead to rice Wang Chang, increased lodging and pest damage. At the same time, the prevention and control of rice pests and diseases throughout the field to maintain water, fry spread all over the field, increased by
