青海省柴达木地区属荒漠草原。为改变这里牧草品种单一,豆科牧草缺乏的现状,以及适应畜种改良,特别是发展青海高原半细毛绵羊的需要,经省、州、县科技人员联合攻关试验,取得了引种新疆大叶苜蓿、齐利普苜蓿、和田苜蓿和紫花苜蓿等品种成功的可喜成果。目前初步统计,这里苜蓿推广面积已达2,000余亩。根据格尔木市草原站对苜蓿进行的覆盖、冬灌等试验,经覆盖者越冬成活率达80~95%,年可刈割三次,共计亩产鲜草5,000公斤以上。经冬灌者亩产鲜草1,531公斤,不覆盖不冬灌的亩产鲜草1,418.4公斤。
Qinghai Province Qaidam region is a desert steppe.

The current preliminary statistics, alfalfa area has reached 2,000 acres. According to the coverage of alfalfa and winter irrigation in Grassland Station of Golmud City, the survival rate of overwintering was 80-95% after covering, and the annual mowing could be mowed three times, with a total yield of 5,000 kg per mu. The winter irrigation per capita yield of fresh grass 1,531 kg, does not cover irrigated per mu fresh grass 1,418.4 kg.
