气象因素对毛竹秆形生长变异的影响

在我国毛竹中心产区的调查分析结果表明 :毛竹的秆形生长同气象因素关系密切 ,在毛竹生长期内不同的具体生理过程 ,各种气象因子的影响程度不同 ,其中的某一或几个因子为主导性或限制性因子并同时综合作用于毛竹的生长发育。但是出笋成竹期和孕笋期的气候因子对毛竹的秆形生长量起决定作用 ,而其中降水因素的作用大于温度因素。此外 ,无论从不同产区 ,还是同一产区内不同地点的毛竹秆形生长变异同气象因子之间相关分析 ,均可知生长地有利的基本温、湿条件(常年的温、湿度条件 )是毛竹生长的前提条件。

The Effect of Weather Factors on the Culm Growth of Moso Bamboo

A series of experiments have been conducted at the central product region of moso bamboo in China and the results indicate that the law of moso bamboo culm growing is closely related to the geography-ecology factors especially the weather. At the different stages of culm growth, the different weather factors have different influence. One or several factors affect decisively when the factors have the influence comprehensively. The weather conditions of which the shoots generate and come out the earth,have the decisive influence on the culms growth, and of which the precipitation is more important than the temperature. Moreover, the good weather condition around a year at the growing site is the base of moso bamboo growth well according to the analysis on the relation between the culm growth and the weather factors at the different producing regions or at the different sites of the same producing region.
