造林密度大小,对林木各个生长发育阶段具有不同的影响.密植合理与否,关系着幼林结束个体生长进入群体生长时期的长短,关系着抚育采伐的强度和次数,关系着林分是否速生丰产和林木材质的优劣.因此,造林密度,不仅对林分生长发育有着巨大的影响,而且在经济上也有重要的意义.为了探求水杉造林合理密度,达到组织水杉合理经营管理和速生丰产的目的.今年七月间,我们对潜江县广华寺,潜江县林科所和江陵城关三地8-17年生不同造林密度的水杉林分,选择标准地进行调查.并进行了林分结构的初步分析.现将材料整理如下:
The density of afforestation has different effects on the growth and development stages of forest trees.Conclusion Whether the close planting is rational or not is related to the length of the individual growth of the end of young forest entering the group growth period and the intensity and number of tending and logging, Therefore, afforestation density not only has a huge impact on stand growth, but also has an important economic significance.In order to explore the reasonable density of afforestation, we can achieve the purpose of rational management and fast-growing and high-yielding of Metasequoia glyptostroboides. In July of this year, we conducted a survey on the afforestation density of Quercus variabilis among 8-17 years of Guanghua Temple in Qianjiang County, Linke Institute of Qianjiang County and Gangneung Chengguan, Preliminary analysis Now the material is organized as follows:
