摘　　要：对野生毛花雀稗不同分株种植处理的成活率、分蘖力、开花结实和根系分布情况进行测定分析,得出以下结论:成活率以处理2(两个分蘖植株)最高,为100%;各处理总分蘖数相差不大;处理2和处理3(两个分蘖植株放置10d)开花结实情况较好,处理1(单个分蘖植株)最差;根系分布情况差异不显著。另对处理2进行了生长速度和再生速度测定,毛花雀稗的生长速度在7月815日之间出现峰值,为5.1cm/d,峰值前半段为保持较低生长水平缓慢增长,5月份后生长开始加快。峰值后半段为保持较高的生长水平缓慢下降趋势,进入11月后生长水平急剧下降。The survive rate, tillering, blossoming and seeding, distributing of root was measured and analyzed. The results showed： The survive rate of treatment 2 （two tillers）can reach 100% that is the highest;The tillering number of different treatment was not discrepant;The blossoming and seeding of treatment 2 and 3 （two tillers placed for 10 days）was preferable, the treatment 1 （one tiller） was the worst;The difference of root distributing was not remarkable. The growth speedof Dallies grass can reach peak value of 5.1cm/d during the eighth to fifteenth July. Dallies grass grows slowly before the peak value, it grows quickly in May. It keeps high growing level after peak value, growing level decreases quickly in November.
