水上农田水下鱼立体开发研究

目的]研究水上农田水下鱼立体开发种植模式。方法]农田种植水稻,水稻采用直播式播种。鱼苗春天放养。结果]水稻在水上生长状况和在大田中生长基本一样,但生育期稍短;鱼在水中正常生长。水上农田水下养鱼农业模式的纯收入为38250元/hm2,与传统农业模式相比,提高了10倍多。结论]水上农田水下鱼的立体开发种植模式是解决耕地面积不足和水体污染的有效途径之一,此外还可以增加农民收入。

Study on Planting Mode of Farmland on Water and Fish in Water

Objective] The research aimed to study the planting mode of farmland on water and fish in water.Method] Rice was sowed directly in farmland on water.And fish was stocked in Spring.Result] The rice growth status in water was similar to that in soil,only the growth stages was short.Fish grew normally in water.The net income of farmland on water and fish in water was 38 250 yuan/hm2,and increased 10 times more than traditional planting mode.Conclusion] Planting mode of farmland on water and fish in water is an effective way to solve the shortage of arable land and water pollution and it can increase the income of farmers.
