肃南高寒山区毛苕子多次刈割生产性能研究

STUDY ON THE PRODUCTIVITY OF HAIRY VETCH AT FREQUENT CUTTING IN SUNAN HIGH COLD ALPINE AREAS

通过对毛苕子进行不同刈割时间与次数对比,发现其生产能力有很大差别。试验证明在高寒牧区人工栽培毛苕子,在整个生育期内刈割两次可获得最高产草量,一茬草与二茬草的最佳刈割期分别为初花期和结荚初期.

Compared different cutting time and different cutting frequency,the productivity of hairy vetch has great difference.The result showed that two cutting times for hairy vetch during the whole life period can reach the maximum yield in the cold high alpine pastoral areas.The best cutting time for the first and the second cut of hairy vetch is at the early period of florensence and podding,respectively.
