综合性立体养殖业的模式

猪舍上层空间养鸡、鸡粪喂猪、猪粪沼气发酵、沼气发电、沼渣喂鱼、沼液注人鱼池和温室、鱼池肥水浇灌稻田。地”“空”“永”立体养殖(含种植),是食物链循环利用和能量多方位转化的综合性生态模式。本模式是以养猪为主体,以沼气发酵为中心枢纽的集鸡、猪、鱼及种植业为一体的综合性立体养殖(种植)业。它具有相应的结构组成,适宜的结构比例和良好的社会效益、生态效益和经济效益。

A Pattern of Comprehensive Stereo-breeding Industry

Chidken to be reared in the upper space of piggrey, chicken manure as pig feeds, pig dung to be fermented as the source of march gas, march gas to be used generating electricity, the sediments of gas-generating pit as fish feeds, liquid from the pit flowing into fish pond and irrigating greenhouse, water form fish pond as fertilizer of paddy fields, this is a comprehensive eclogical pattern composer of circulating utilizalion of food chain and multiplc-direction transformation of energy. Pig-breeding was the principal part of this pattern, and its key position was gas-generating by fermented pig dung. This is a comprehensive stereo-breeding industry combined chicker; pig, fish, inductries with planting indurstry. The pattern possessed corresponding structure, appropriate ratio and better social, ecological and economic efficiencies.
