楚雄州引种紫花苜蓿品种的研究初报

A Preliminary Study on Introduction of Medicago Sativa in Chuxiong

2004年云南省楚雄州地区13个试验点对3个不同紫花苜蓿品种进行了比较试验。结果表明:土壤酸度、海拔高度不是限制紫花苜蓿生长的主要因子;年降雨量和刈割次数对紫花苜蓿的干物质产量影响较大,为限制其生长的主要因子。试验表明,在云南省楚雄州地区,适宜大面积推广应用的紫花苜蓿品种为四季旺紫花苜蓿(Medicago sativa cv.Siriver)。

Three different species ofMedicago Sativa were tested at 13 trail plots in Chuxiong, Yunnan in 2004.The results indicates that neither the soil acidity nor altitude was the major factor restricting the growth ＇of Medicago Sativa, but annual rainfall and cutting frequency had great impact on dry matter yield of Medicago Sativa, which were the major factors affecting their growth. It also suggested that Medicago sativa cv. Siriver was suitable for large scale extension in Chuxiong of Yunnan province.
