摘要
在"稻萍鱼"、"稻萍鸭"等有机水稻栽培模式中,红萍平生于稻田水面,生长繁殖快,产量高,既为水稻提供充分的肥料源,又可作为鱼鸭等动物的青饲料。放养红萍可有效地提高水稻田的生产力,并明显促进稻田生态环境的持续良性循环。
In organic farming models of rice-azolla-fish and rice-azolla-duck, azolla has been on the surface of paddy field with fast growth and high yield. Azolla can offer abundant fertilizer fi^r rice and greenfeed for animal, such as fish and duck. Growing azolla raise the productive potentialities of paddy field, and further a virtuous circle of its ecological environment.
