沙打旺(Astragalus adsurgens)系豆科黄芪属多年生草本植物。1975—1979年陕西吴旗县飞播沙打旺试验成功后,在我国北方推广面积逐渐扩大。在试验和推广的十年期间,我们对吴旗飞播沙打旺与荒山植被产量进行了对比研究,为评价沙打旺草地生产力,估算生产潜力及合理利用、改良草地,提高草地生产力提供依据。一、试验区自然条件试验区设于陕西延安地区北部的吴旗
Astragalus adsurgens is a legume Astragalus perennial herb. From 1975 to 1979, the spreading area in Wuqi County, Shaanxi Province was successfully tested, and the area for its promotion in northern China gradually expanded. During the ten years of experiment and promotion, we conducted a comparative study on the yield and vegetation yield of Wuqifei sowing and barren hills, and provided the basis for evaluating the productivity, estimating production potential and rational utilization of grassland, improving grassland and improving grassland productivity. First, the test area of natural conditions Experimental area is located in northern Shaanxi Yan’an Wu Qi
