摘要
1983～1986年在宁夏盐池县用沙打旺与禾本科牧草进行的混播试验表明,混播组合牧草产量均高于单播,其中沙打旺+老芒麦组合产量最高,为160.01公斤/亩,分别比沙打旺+披碱草、沙打旺+无芒雀麦、沙打旺及禾本科牧草单播高12.0％、29.4％、44.1％、100～200％。同时,混播牧草营养枝增加,茎叶柔软,营养成分较全面,各类家畜均喜食。
The experiment was carried out at Si Dunzi, Yangchi county, Ningxia Hui Autonomous Region from 1983 to 1986. It shows that mixed seeding of Astragalus ad,surgens and grass herbage could increase the tempreture and moisture of the soil. It is beneficial to the herbage growth- The yield of mixed seeding is much higher than that of monocroping. There is a difference in yield between differnt conbination of mixed seeding. For example, the yield of the conbination of A. ad surgans+Elymus sibiricus is the hightest,compared with thegroup of A. ad surgens+E.dahuricus, A.ad surgens+Bromus inermis,A.ad surgens and grass.The yield 160.01kg/mu of A.ad surgens+E.sibiricus more than others by 12.0%,29.4%,44.1%,100.0-200.0%, respectively. Moreover,the herbage in mixed seeding is rich in nutrition. It has more nutrtitonal branches.Their soft stems and leaves are palatable for dosmetic animals.
