In order to deeply explore the nutritional value of legume and gramineous forage resources,Astragalus adsurgens Pall.was mix-silages with Zea mays L.and Sorghum bicolor（L.） Moench.Using sensory and nutritional fcomposition as evaluation indexes,nutritional values of the mix-silage under 1∶0,3∶1,1∶1,1∶3 and 0∶1 proportion were studied.The results showed that A.adsurgens Pall.silage had the highest nutritional value,but the fragrance was weak,and the structure of stem and leaf was damaged.As the proportion of A.adsurgens increased,the CP content increased while the content of NDF and ADF decreased.When A.adsurgens was respectively mixed with Z.mays and S.bicolor at the proportion of 3∶1,the mixed silages featured excellent sensory.Compared with Z.mays and.bicolor silages,the CP content increased by 82.12% and 116.73% respectively.The NDF and ADF contents decreased by 16.07%,21.95%,23.07% and 32.30% respectively.Besides,the RFV content increased by 27.41% and 42.21% respectively.It proved to be the optimal proportion for the mixed storage between A.adsurgens and Z.mays L.and between A.adsurgens and S.bicolor（L.）Moench.The research findings will lay theoretical and practical basis for A.adsurgens ensiling.In conclusion,3∶1 is the optimal ratio of A.adsurgens mix-silages with Z.mays and S.bicolor,which can achieve the ideal nutritional effect.The above results can provide theoretical basis and practical guidance for rational utilization of different forage and feed crops.
