摘要
在高原地区退耕还草示范种植中,利用牧区广泛种植的一年生禾本科牧草燕麦Avena sativa与进口的多年生禾本科牧草细茎冰草Efymus trachycaulum混播。结果表明:燕麦和细茎冰草混播既能克服单一种植多年生禾本科牧草时的杂草危害问题,也能使退耕当年就获得较好的经济效益,解决了种植当年的收成问题,使项目建设的效益及早得到体现。第1年燕麦开花期鲜草产量为2.49 kg/m2,细茎冰草第2年能够良好生长,第2年细茎冰草开花期鲜草产量为1.48 kg/m2,生长后期鲜草产量为1.76 kg/m2。
As a demonstration of converting cropland to pasture in the plateau region, oat （Arena sativa） and slender wheatgrass （fymus trachycaulurn） was sown as mixed pasture. The result showed that the method not only solve the problem of weeds, but also obtain better economic benefits. Oat fresh grass yield at the flowering stage was 2.49 kg/m^2 in the first year. Slender wheatgrass grew better in the second year, the fresh yield was 1.48 kg/m^2, and reached to 1.76 kg/m^2 at later growth stage.
