不同生境对岷山红三叶鲜草产量和种子的影响

The Technology Research of Stem-leaf Separation for Trifoliumpretense cv. M inshan

在岷县选择具有代表性的3个试点，进行岷山红三叶草产量和种子产量的对比试验。结果表明，在海拔2450—2700m，降水量700mm左右的区域，最适宜岷山红三叶干草生产；在海拔2400m以下，降水量600mm以下的区域适宜生产种子。

Selected 3 pilot sites of representative in Minshan county. Tested the grass yield and the seed yield of the Trifoliumpretense cv. Minshan. The results showed that, at the altitude of 2 450-2700 m, rainfall of 700 mm area, that fit for the hay growth of Trifolium pretense cv. Minshan, under the altitude of 2 400 m, and the rainfall less than 600 mm was fit for the seed growth.
