林下套种对南方红豆杉树冠形态结构及干形变化的影响
The Effect of Interplant Under the Canopy on Taxus chinensis var. mairei Crown Structure and Stem Form Changes
摘要
Abstract
In order to realize the efficient cultivation of Taxus chinensis var. mairei, the crown structure char-acteristics, vertical distribution of branches and growth relationship between branch length and branch diameter of the interplant under the canopy pattern and the pure forest cultivation pattern cultivated 15 years Taxus chinensis var. mairei stands were studied in Mingxi, Fujian. The results showed that cultivation patterns had significant effects on the crown structure Taxus chinensis var. mairei vertical distribution of branches, growth relationship between branch length and branch diameter and stem form changes in crown had significant difference in different cultivation patterns. With the interplant under the canopy pattern, most trees of T. chinensis var. mairei were available to form the absorption ability of sunlight and the higher photosynthetic with wide and long conical-shaped crown. The smal-ler first lateral branch number and more full stem form in crown were contributed to cultivate lesser and rarer knot full stem. There were the important factors of fast-growing and excellent timber for the forest regeneration pattern of T. chinensis var. mairei. Cultivation patterns had significant effects on the growth of branch length and branch diam-eter of T. chinensis var. mairei.关键词
