摘    要: 慈竹生态研究的结果如下:(1)用逐步回归分析模型分析,慈竹竹丛密度仅与土壤厚度关系密切.慈竹高度、胸径与海拔成正相关。(2)用逐步回归法分析笋生长量与气候因子间的关系,证明笋的逐日生长量与湿度,温度和降雨量有较密切关系,笋在一天内有两个生长高峰。(3)自然条件下,出笋数主要与土厚密切相关,退笋数受母竹高和出笋数所制约,好笋数主要受土厚和竹高影响。

关 键 词:样方法  逐步回归模型  多项式回归  出笋

Abstract:Neosinocalamus affinis is a bamboo species distributed most widely and cultivated for a long time. The following problems about it is discussed in this paper.1) The growth of the bamboo species under various stand conditions shows that there is no significant correlation between the density of the clump of the bamboo and the stand conditions, that the density is limited mainly by the thickness of soil, and that the height and the breast-height diameter of the bamboo correlate with the altitude above sea level.2) It is shown that the diameter and the height of the bamboo and its clump density decrease with the decrease in thickness and humidity of the soil from the valley to the top of the slope when the series of the bamboo in the valley is investigated.3) Study on the growth and development of the bamboo shoots shows that the increment of the bamboo correlate mainly with yesterday's humidity and today's temperature. The growth curve exhibits tow peaks for one day; the first is before 10 a.m., the second is after 3 p.m.. The number of the bamboo shoots which appeared above the ground correlate with the thickness of soil, whereas the number of the bamboo shoots which disappeared above the ground is mainly limited by the height of the mother bamboo and the number of the bamboo shoots which appeared above the ground. The number of healthy bamboo shoots is mainly affected by the thickness of soil and the bamboo height.
Keywords:Sichuan Neosinocalamus affinis  Bamboo shoot  Dynamic study
