| 摘 要： | 应用Harper的构件生物结构和种群生态学理论,对海子坪天然毛竹种群生长规律进行了系统的研究。结果表明:天然毛竹竹笋出土的持续时间约为50 d左右,以4月5日前后5 d的为出笋高峰;高生长持续51 d左右,遵循"慢—快—慢"的规律,呈Logistic增长,且有明显的昼夜生长节律;地径生长期在竹笋出笋后的21 d基本停止;温度是影响竹笋—幼竹高生长的主要生态因子。

| Abstract: | According to Harper's module and population ecology theory,the growth and rhythm of natural Phyllostachys heterocycla cv.pubescens clonal population were studied.The main results were as follows: the sprouting period of bamboo shoots lasted about 50 days and before-after 5 days of Apr 5 was the peak phase.The height growth lasted 51 days,following the rules of "slow-quick-slow",displaying Logistic growth and showing a significant day-night growth rhythm.The growth of basal diameter stoped after the 21th days of the first sprouting.Temperature was main ecological factor infuencing the growth of bamboo shoots-young bamboo. |
