摘要
在海拔近４０００ｍ的高寒地区进行高矮禾草不同比例的混播试验，结果表明，以多叶老芒麦３０％＋中华羊茅７０％和垂穗披碱草７０％＋西北羊茅３０％第二年地上生物量优于其它混播处理和单播，地上生物量分别为１４１２．８ｇ／ｍ２和１４３２．２ｇ／ｍ２，接近一年生燕麦。
Mix-sowed high and low herbage in different proprtion at 4000m sea level. The result showed that mix-sowed Elymus sibircus l. 30%+ Festuca sinensis Keng 70% and Elymus nutans Griseb 70%+ Festuca Kryloviana Rererd 30% respectively. The biomes aboveground surpassed the biomes of other mix-sowed species and single sowed. The biomes aboveground are 1412.8g/m2 and 1432.2g/m2 respectively. The biomes nearly equal to the biomes of annual oat.
