摘  要:
在贵阳市长坡岭林场桂竹引种地,于2010年和2011年对桂竹出笋、高生长的过程进行了观测,结果通过最优分割法(Fisher)进行聚类分析,将桂竹出笋过程和高生长过程划分为初期、盛期和末期。出笋盛期的笋量占全期的56.3%,高生长盛期生长量占全高的72.3%,其高生长的数学模型为三次函数模型;桂竹的高生长存在昼夜差异,总的趋势是夜生长量大于昼生长量,占全天生长量的56.7%,高生长最慢在中午12时左右,最快在晚上24时左右。

摘  要:
The shooting character and height-growth of Phyllostachys bambusoides were investigated in Changpoling Forest Farm of Guiyang City from 2010 to 2011.The results showed that the shooting process and height-growth of Ph.bambusoides might be divided into the initial stage,peak stage and terminal stage.The number of shoots at the peak stage accounted for 56.3% of the total,and the shoot increment of height-growth accounted for 72.3% of the total.The process of height-growth of Ph.bambusoides could be simulated effectively with the model of Cubic function.The height-growth of Ph.bambusoides showed a difference between the daytime and the nighttime,and the height-growth in nighttime accounted for 56.7% of the total growth.The low point of the height-growth was at 12:00 and the ceiling at 24:00 of night.
