牧草在相应的生态条件下栽培,所表现出的性状优劣程度是决定一个地区推广价值的依据。凉山属亚热带高山区,境内海拔差异较大,形成了多生态的农牧生境条件,草场建设中重点应选择适应性广,生长繁殖力强的豆科牧草品种。据此,我们在引种栽培试验的基础上,于1980年在海拔2000米与3000米的地区进行了白三叶(Trifolium repenl),红三叶(Trifolium pratensel),地三叶(Trifolium subterraneuml)的区域适应性试验,试验结果看出地三叶表现差,材料不完整,白三叶、红三叶表现好。
Forage cultivation in the corresponding ecological conditions, the performance of the merits of the degree is to determine the value of a region to promote the basis. Liangshan is a subtropical high-mountain area with large differences in elevation within the region, forming a multi-ecological environment for agro-pastoral habitat. In the construction of grassland, legume forage varieties with wide adaptability and strong growth and reproduction should be selected. Based on the introduction and cultivation experiments, we conducted Trifolium repenl, Trifolium pratensel, Trifolium subterraneum, and Trifolium subterraneum in 1980 at altitudes of 2000 and 3000 meters. Regional adaptability test, the test results showed that poor performance of the three leaves, the material is not complete, white clover, red clover performance is good.
