摘要
对水富县引种的撑绿竹出笋规律进行了研究,结果表明:撑绿竹出笋期在5月下旬至9月下旬左右;退笋多出现在末期;高生长的Logistic曲线模型为:H=867.168/(1+e4.793-0.725t);昼夜总生长量达7.09cm,夜间生长量几乎是白天生长量的1.76倍。
The bamboo shoots emergence rhythm of introduced Bambusa pervariabilis x Dendrocalamopsis grandis was studied in Shuifu County, Yunnan. The results indicated that the period of bamboo shoots was from late May to late September, in which degraded shoots often occurred in the late of Sep. The logistic equation of height growth was：H = 867. 168/（ 1 ＋ e^4.793-0.725）. The height of growing during a day and night was about 7.09 cm,and the growing height during a night was 1.76 times than that during a day.
