| 摘 要： | 通过对西藏拉萨河谷地区紫花苜蓿的刈割试验,构建了拉萨河谷地区紫花苜蓿刈割生长动态模型,并分析了刈割次数对紫花苜蓿干鲜草积累量、刈割高度、干鲜比、营养成分的影响.分析结果表明,紫花苜蓿在西藏拉萨河谷地区具有很大的发展潜力,在管理措施保障条件下,紫花苜蓿刈割1次的干草年积累量可达1645 g/m2,刈割2次达2128 g/...

| Abstract: | Through systematic research of the cutting areas in the Lhasa river valley,dynamic models of Medicago sativa growth were structured to simulate and forecast the accumulation of dry matter and fresh forage of M.sativa in different cutting schemes.The effects of cutting times on accumulation of dry matter and fresh forage,height,dry weight/fresh weight ratio,nutrient component of M.sativa were studied and different cutting schemes were developed to suit different objectives.Cutting three times a year at branc... |
