The mixed-sowing experiments of Astragalus adsurgans and gramineas in Yanchi County of Ningxia from 1983 to 1986 showed that the yield of mixed-sowing forage was higher than that of unicast, and the combination yield of Astragalus adsurgata + Elymus sibirica was the highest (160.01 kg / mu) They were 12.0%, 29.4%, 44.1% and 100% -200% higher than the unicast and the grass of Astragalus adsurgens + Elymus herb, Astragalus adsurgens + Bromus inermis, Astragalus adsurgens and grasses respectively.
