摘要
2005～2006年对建植当年的混播草坪采用不同的停止修剪时期和修剪强度的试验。结果表明:频繁修剪促进了秋季分蘖,但减少了主茎根和分蘖节中的物质积累,这是导致草坪越冬率降低的主要原因。因此,在海南州草坪建植当年修剪应在9月初停止,并适当延长秋季修剪间隔期。
The experiment about effect of autumn pruning on rate of overwintering of turf was carried out during the period of 2005 and 2006. The results showed that frequent pruning promoted autumn tiller, but it would reduce the matter accumulation of main root and tiller nodes, which was the main reason of reducing overwintering rate of tuff. So, the turf pruning should stop in early September, and the interval of autumn pruning should be prolonged.
