羊草草地一年两次刈割可行性的研究

A Feasibility Study on Mowing Two times a Year in Leymus chinensis Grassland.

羊草草地是优良的割草场 ,通常一年内刈割一次。通过四年的实验证明 ,羊草草地不施加措施一年内刈割两次对产量和环境均造成不良影响 。

Leymus chinensis grassland is an excellent mowing range. It is usually mowed one time annually. The results of 4 years of test showed: Without improving measure, mowing two times a year would lead to some harmful effects on the yield and environment of L. chinensis grassland. With irrigating and fertilizing, mowing two times a year could increase the yield and quality of L. chinensis.
