近年来,随着养殖模式向舍饲集约化方向的转变,人工牧草得以大面积推广。西大滩为宁夏回族自治区银北典型盐渍化区,生态环境脆弱,植被差。试验区经多年综合治理,农业基本生产条件得到一定改善,为了充分利用西大滩闲置荒地资源,在改善生态环境的同时发展节粮型草食家畜[1],充分发挥耐盐牧草的经济效益,在西大滩种植耐盐碱、抗性强的牧草,通过种草养畜,就地转化,进而提高牧草综合利用效率。
In recent years, artificial breeding has been widely promoted with the shift of breeding mode to the intensive feeding. Xida Beach is a typical salinization area in North of Ningxia Hui Autonomous Region, with fragile ecological environment and poor vegetation. In order to make full use of the idle wasteland resources in Xidatan, we should improve the ecological environment and develop grain-saving herbivorous livestock at the same time [1], give full play to the economic benefits of salt-tolerant forage grass, In the West Bank planted saline-alkali resistance and strong pasture, grass by raising livestock, in situ conversion, and thus improve the comprehensive utilization efficiency of pasture.
