摘　　要：在科尔沁沙地将沙生冰草、扁穗冰草、蒙古冰草分别与黄花苜蓿间行混播,设1∶0、3∶1、5∶1和7∶1共4个混播比例建植混播草地,研究混播比例对混播当年产量的影响。结果表明,混播比例和草种组合对播种当年冰草-黄花苜蓿各草种产量和草地群体总产量影响显著,其中混播比例5∶1的沙生冰草与黄花苜蓿混播组合总产量最高,为144.33 g/m^(2),显著高于各处理组合群体总产量。In Horqin sandy land,Agropyron desertorum(Fisch.)Schult.,A.cristatum(L.)Gaertn.and A.mongolicum Keng were separated from alfalfa(Medicago falcata L.)inter-row mixed sowing.We set up four mixed sowing ratios of 1∶0,3∶1,5∶1 and 7∶1 to establish mixed grassland,and studied the effects of mixed sowing ratio on the yield of the current year.The results showed that the mixed sowing ratio and the combination of grass seeds had significant effects on the yield of each grass species and the total yield of grassland populations of A.cristatum-M.falcata in the year of sowing.Among them,the mixed sowing combination of A.cristatum and M.falcata with a mixed sowing ratio of 5∶1.The total yield was the highest(144.33 g/m^(2)),which was significantly higher than the total yield of each treatment combination group.
