经观察：白夹竹鞭消生长期6～11月．鞭分布在土壤上层1～15cm．鞭年生长1m左右．笋芽3～4月萌动．笋从5月初长出地面至5月底不再出笋，历时28天左右．每公顷大年出笋10000个左右，上林率为29．54％，虫退笋率为43．98％，自然退笋率为26．48％．上林率，大年高于小年，初地、盛期出笋高于末期出笋。竹笋从出土到长成幼竹，历时60天左右．竹笋高生长，一般夜晚稍大于白天．笋箨有吐水现象．1986～1988年，林缘、路边个别竹子开花，连开3年，未见竹枯死．成竹胸径越大，秆越重，植株越高。
The observation: white bamboo whip eliminate growth period 6 ~ November. Whip distribution in the soil layer 1 ~ 15cm. Whip years about 1m growth. Bamboo shoots 3 ~ April germination. Bamboo shoots grow from the ground in early May to the end of May no longer shoots, which lasted 28 days. The number of shoots per hectare is about 10,000, the rate of Shanglin is 29.54%, the rate of retreat shoots is 43.98% and the rate of natural retreat shoots is 26.48%. Shanglin rate, New Year was higher than the small, early, peak shoots higher than the last stage of bamboo shoots. Bamboo shoots from the excavated to grow into young bamboo, which lasted 60 days. High growth of bamboo shoots, usually slightly larger than during the day at night. Bamboo shoots have spit water phenomenon. 1986 ~ 1988, the edge of the forest, individual bamboo flowers on the curb, even for three years, no dead bamboo.
