Study on forage mixture sowing in Ningxia desert steppe

In order to explore the suitable combination of mixed artificial grassland in desert steppe, the Medicago sativa L. was mixed with Agropyron mongolicum Keng, A. cristatum (L.) Gaertn, A. desertorum Schult and Bromus inermis Leyss with the proportion of 2颐1 respectively to compare the mixed pasture爷s growth conditions and mixed effects. The results showed that the combination of M. sativa L. and B. inermis Leyss displayed the best growth and mixed effects, followed by Medicago sativa L with Agropyron cristatum (L.) Gaertn and M. sativa L. and A.n mongolicum Keng, while M. sativa L. and A. mongolicum Keng was the worst, during the establishment year. And we can conclued that, in desert steppe, the way of mixture sowing can significantly improve the grassland biomass. In the meantime, the mixture of legume and poaceae is a preferadle mixed combination, which is conductive to both kinds of forage self-growth.
