摘要
对黑龙江肇州羊草+杂类草群落在一年的最佳刈割次数和时间进行了探讨。试验结果表明,不同刈割次数和时间对群落当年的地上生物量都有显著的影响。在该地区,一年应以1至2次刈割群落为宜。若一年刈割2次,则以7月5日与9月5日、7月20日与9月20日、7月5日与9月20日三个处理能获得较高的地上生物量产量;若一年刈割1次,则以7月末至8月5日之前为最佳;一年刈割三次会降低群落地上生物量的产量,因此,该群落一年最多不能超过两次刈割。
This paper deals with the optimum mowing times and periods of Anerurolepidium chinense+mesophytic Herb community in a year.Theresuits show that the diffierent mowing times and periods greatlyeffect the community aboreground biomasses in the investigating year.Inthes region,it's better to use the community herbage once or twice in awhole growing year.When we use it twice in a year,the optimum mowingpcriods should be on July 5 for tue first mowing and second mowingperiod should be on septemper 5;on July 20 for the first and second onseptemper 20;on July 5 for the first and second on septimper 20: Andonce a year,the best time for starting should be from late July toAugust 5. The yield of community herbahe must be cut dow three times touse in one year;therefore,it' s better to use the community herbage nomore than twice in one year.
