辽河下游三角洲近年出现了水田高效复合种养模式,这种模式的组成是水田埝埂种豆、田内养蟹、鱼、牛蛙、或行间套种平菇。其中水田养蟹在辽河下游三角洲地区发展十分迅猛,已取得了显著的经济效益、社会效益和生态效益。水田养蟹是利用水田既种稻又养蟹的一种新的生产方式。它将种植业与养殖业巧妙地结合在同一生态环境中,充分利用稻蟹之间的共生关系,使原来稻田生态系统中的物质循环和能量转换向更为有利的方向发展,
Liaohe River delta has emerged in recent years, paddy field high-performance compound planting and breeding mode, this model is composed of paddy fields paddy beans, field crabs, fish, bullfrog, or interplanting mushrooms. Among them, paddy field crab farming developed rapidly in the delta of the lower reaches of the Liaohe River and achieved remarkable economic, social and ecological benefits. Paddy field crab farming is the use of both paddy and crab breeding a new mode of production. It combines plantation and aquaculture skillfully in the same ecological environment and makes full use of the symbiotic relationship between rice and crab to make the material circulation and energy conversion in the original rice paddy ecosystem develop in a more favorable direction.
