应用草地农业系统理论发展半农半牧区农村经济

APPLY GRASSLAND AGRICULTURAL SYSTEM THEORY TO THE DEVELOPMENT OF THE RURAL ECONOMY IN SEMI AGRICULTURAL AND SEMI PASTORAL AREA

在半农半牧区，草地农业系统的植物生产过程应包含种植多年生植物和一年生饲料作物两方面，动物生产过程是以草食畜禽为主综合发展的畜牧业生产。把草地农业系统理论应用到生产实践中，就是广泛建立生态模式家庭牧场，以期达到增加收入和农牧业持续发展的目的。规划固定饲料作物用地可使耕种农业形成新的三元（即粮食作物、经济作物、饲料作物）种植结构。畜牧业的发展和农业种植结构的变化，必将促进农村经济的有效和可持续发展。
