茭白田间套养河蟹,即在田块中既种茭白又养河蟹,可以充分利用茭白田间水体的生态环境,茭白行、株距较宽,可为河蟹提供足够的生活空间,盛夏高温季节,茭白叶高挺且宽,丛生繁茂,成为天然的遮荫物,十分有利于河蟹避暑度夏。河蟹喜食水中昆虫、底栖动物等饵料,河蟹排泄物又是茭白优质肥料,使茭白与河蟹共生相得益彰,降低栽植茭白与河蟹生产成本。一般亩产茭白800—1000kg、商品蟹亩产50—60kg。因此,茭白田间套养河蟹是充分利用水资源,积极调整农村产业结构,增加农民经济收入的好项目。
The cultivation of crabs in the field of white rice, that is, in the plots of both white and raise crabs, you can take full advantage of the ecological environment of the water field, the white line, wide spacing, for crabs to provide adequate living space, summer high temperature season, Tall and wide, lush, become a natural shade, is very conducive to summer crab summer.
