旱地覆膜条件下8个紫花苜蓿品种生产性能比较研究

Comparative Study on Production Performance of 8 Alfalfa Varieties under the Condition of Film Mulching in Dry Land

在干旱半干旱的定西地区,采取随机区组排列的方式,对WL363、WL343、WL319、WL168、挑战者、康赛、阿迪娜、多叶等8个苜蓿品种进行产草量、茎叶比、粗蛋白含量等指标测定,结果表明:挑战者、阿迪娜、WL343、WL319为高产品种,平均每公顷产鲜草52 500kg以上;康赛、阿迪娜、多叶苜蓿、WL343、WL319粗蛋白含量较高,均在14.5%以上。

In the arid and semi-arid area of Dingxi, the way of random group arrangement was adopted for 8 alfalfa： WL363, WL343, WL319, WL168, Challenger, Kangsai, Adina, multi-leaf. Grass yield, stem leaf ratio and crude protein content and other indices of these alfalfas were determined. The results showed that Challenger, Adina, WL343, WL319 were high-yielding varieties （52 500kg per hectare） ; Kangsai, Adina, multiqeaf, WL343, WL319 were of higher crude protein content （more than 14.5%）.
