同一物种的各个器官之间都有一定的结构关系。这种结构关系是物种遗传特性的表现,同时也受环境条件的影响。本文主要阐明毛竹秆形(包括直径、高度、壁厚、重量等)结构特点,及其与气候条件的关系。从而,为研究毛竹林产量和编制竹材用表提供依据。 毛竹(Phyllostachys pubescens)原产我国,自然分布在北纬23°—33°、东径104°—122°、海拔1200米以下的一些地区,年平均气温12°—22℃,年降水量800—2200mm。1958至1980年期间,我们调查和收集了十三个竹区资料,其中我国原产区十二个,日本引种区一个,共计标准地224块,标准竹276l株(表1)。根据这些资料,整理如下:
There is a certain structural relationship between the various organs of the same species. This structural relationship is a manifestation of the genetic properties of the species and is also influenced by environmental conditions. This paper mainly clarifies the structural characteristics of the culm (including diameter, height, wall thickness, weight, etc.) of the bamboo and its relationship with climatic conditions. Thus, for the study of bamboo production and bamboo preparation table provide the basis. Phyllostachys pubescens are native to China and are naturally distributed in some areas at 23 ° -33 ° north latitude and 104 ° -122 ° east longitude with an altitude of 1200 meters below sea level. The annual average temperature is 12 ° -22 ℃ and annual precipitation is 800-2200 mm . During the period 1958-1980, we surveyed and collected thirteen bamboo resources, of which 12 were in our country of origin and one was in the introduction area of Japan. There were a total of 224 standards and 276l standard bamboo (Table 1). According to these data, collated as follows:
