农牧结合生态工程及其种植模式研究

Eco-engineering of integration of crop-livestock and its planting model.

农牧结合生态工程是个复杂的农业生态、经济和技术系统工程,它由植物(种植业)、动物(养殖业)和微生物(连接种养业)3个子系统组成,其关键是建设以“四三二一”畜牧业生产模式为主要内容的高效节粮型畜牧业生态工程。农牧结合种植结构主要模式有“一粮一饲”、“一粮一经”、“两饲一粮”和“一粮一经一饲”等多种模式。农牧结合型种植模式的核心是因地制宜建立以粮食生产为基础,饲料生产为重点,经济作物生产为动力,并有机配合和协调发展粮-经-饲三元种植新模式,3种作物种植参考比例为5:2:3。

Eco-engineering of integration of crop-livestock is a complex engineering of agro-ecological, economical and technological system. It is composed of three sub-systems including plant (crop industry) , animal (livestock industry)and microbe (linking crop and livestock industry),in which the crux of matter is to set up an effective and saving grain animal production eco-engineering system called '4, 3, 2, 1 'animal production model. The main planting models of integration of crop-livestock was found such as 'one crop and one feed', 'one crop and one economy plant', 'two feeds and one crop 'and 'one crop-one economy plant-one feed'. The core of planting models of integration of crop-livestock is setting up aco-ordinated'crop-economy-feed'planting model with crop production as base,feed production as focal point, economy plant production as power. The suggesting proportion of the three plants is 5 : 2 : 3.
