修剪对高尔夫球场果岭草坪光滑度的影响

以美国高尔夫球果岭草坪锦标赛球速经验值作为基础,研究了影响球速的主要因素及相互作用的机理。结果表明:不同留茬高度的果岭草坪在株数、叶片数、叶面积和叶面积指数方面随留茬高度降低而降低。各项密度指标同光滑度、均匀度具有较好的联动关系。当叶面积指数和盖度分别为1和100%时,此时的叶片数、叶面积、植株数和叶面积指数均可作为指示密度的良好指标。当4种因子处于最佳平衡状态时,光滑度会达到最高速度水平。光滑度是系统中4种因子综合作用的结果。

Study on the trimming effects on the smoothness of green turf in Golf Tournament

Based on the golf ball's speed experience value of golf green tournament in the United States,the main factors affecting the speed and the mechanism of mutual connections and interactions were studied.The results showed that the number of plants and leaves,leaf area and leaf area index were decreased with the decreasing of stubble height.The smooth degree,uniformity and the density index had better linkage and obvious difference.When the leaf area index and coverage were 1 and 100 ％,the leaf number,leaf area,plant number and leaf area index could be used as a good indicator of the density.When 4 factors were in the best balance,the smoothness would reach the highest speed level.The smooth degree was the result of 4 factors in the system.
