为提高奶牛单产和总产水平,解决优质饲草饲料供应不足的问题,以干物质产量为筛选要素开展适于云南省巍山县种植的紫花苜蓿品种试验。选择速生、威斯顿、三得利、游客和赛特5个品种的紫花苜蓿,于建植后第1、2、3年分别测定干物质产量。结果显示:3a平均干物质产量前3名的是威斯顿、三得利和速生紫花苜蓿,分别达到19.42、18.90和18.28t/hm2。说明这3种紫花苜蓿在巍山这类环境地区适应性较强,值得大量推广应用。
In order to improve the yield and total level of dairy cows, and to solve the problem of insufficient supply of high quality fodder and fodder, the experiment of alfalfa variety suitable for planting in Weishan County of Yunnan Province was conducted with dry matter yield as the screening factor. Fast growing, Weston, Suntory, tourists and Saite 5 alfalfa varieties were selected to determine the dry matter production in the first, second and third year after planting. The results showed that the top three dry matter yield of 3a was Weston, Suntory and fast-growing alfalfa, reaching 19.42, 18.90 and 18.28t / hm2, respectively. This shows that these three kinds of alfalfa in Weishan strong adaptability to such environmental areas, it is worth a lot of promotion and application.
