摘　　要：为研究沙生冰草与黄花苜蓿适宜的播种比例,将沙生冰草与黄花苜蓿按照3∶1、5∶1、7∶1的比例交叉混播,以单播为对照,观测沙生冰草的株高等生长动态。结果表明:混播沙生冰草株高显著高于单播,其中7∶1的株高最高;枝条重以单播的沙生冰草最高,其次是7∶1,混播显著低于单播;混播5∶1的枝条叶面积最高,显著高于其他各比例的沙生冰草;混播比例对沙生冰草的生长影响显著。In order to study the suitable sowing ratio between agropyron desertorum and alfalfa,cross sowing of agro⁃pyron desertorum and alfalfa was carried out according to the mixed planting ratio of 3:1,5:1 and 7:1,and the growth dynamics of plant height of agropyron desertorum was observed with single sowing as control.The results showed that the plant height of mixed sowing was significantly higher than that of single sowing,and the plant height at 7:1 was the highest.The branch weight of monoculturing agropyron desertorum was the highest,followed by 7:1,and the branch weight of mixed planting was significantly lower than that of monoculturing.The branch and leaf area of mixed planting 5:1 was the highest,which was significantly higher than that of other proportions.Mixed-planting ra⁃tio had a significant effect on the growth of Agaricum sargassum.
