摘要
动物生产是西北地区传统的农业产业,对于农业结构调整、发展草地农业具有十分重要的战略意义。本研究选择青藏高原的玛曲、黄土高原的环县和河西内陆干旱区的民勤为主要代表,认为天然草地退化加剧、面积缩小,栽培草地面积不足、品种单一且产量低,畜群管理不善等阻碍了草、畜生产系统的天然耦合联系,也是限制区域动物生产的根本原因。为此,本研究提出以暖棚养殖+冬季补饲,家庭联户经营式,异地短期育肥以及草-畜耦合作为西北主要生态区家畜生产的发展模式。
Animal production is the traditional agricultural industry in northwest China,and has an very important strategic significance on agricultural structure adjustment and grassland agriculture development. This aryicle choose Maqu,Huanxian and Minqin County as examples,thinking that the serious natural grassland degradation and the shrinking area,insufficient cultivated grassland area,single varieties and lower production,the mismanagement of herds et al that hindered the natural connection of grass and livestock production system,and also the main reasons to restrict the animal production. So this research present that,the in house cattle breeding + winter feeding,family joint household,short term fattening and coupling of grassland and livestock systems are the main livestock production development mode coupling in northwest of China.
