对毛苕子不同刈割时间与次数的生产性能进行了对比，发现其生产能力有很大差别。试验证明，在高寒牧区栽培毛苕子，在整个生育期内刈割２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。
The results showed that the productivity of Maozizi different cutting time and the number of production performance were compared and found a great difference. Experiments show that in the alpine pastoral cultivation hairy seeds, mowing two times during the whole growth period to obtain the maximum yield, the first crop and the second crop of the best cutting period were early flowering and early pod.
