不同树种混交对闽西地区闽粤栲生长的影响研究

Study on the Influence of Different Tree Species Mixing on the Growth of Castanopsis fargesi in Western Fujian

在闽西上杭县开展闽粤栲(Castanopsis fissa)与杉木(Cunninghamia lanceolata)和马尾松(Pinus massoniana)混交造林试验,探讨针阔混交造林对闽粤栲幼林的生长效应。通过分析不同混交模式造林对闽粤栲成活率、树高、地径、冠幅等因子的影响可知,不同混交模式造林对闽粤栲的高生长和地径影响极为显著,对冠幅生长影响显著;故采取针阔混交造林可以有效促进闽粤栲的生长,是一种值得推广的闽粤栲的培育造林模式。

The mixed afforestation experiment of Castanopsis fissa,Cunninghamia lanceolata and Pinus massoniana was carried out in Shanghang County,western Fujian Province,to explore the growth effect of mixed coniferous and broad-leaved forest on the young Castanopsis fargesi forest.Through the analysis of the effects of different mixed modes of afforestation on the survival rate,tree height,ground diameter,crown diameter and other factors of Castanopsis hystrix,it can be seen that the effects of different mixed modes of afforestation on the height growth and ground diameter of Castanopsis hystrix are extremely significant,and the effects on the crown diameter growth are significant;Therefore,the coniferous and broad-leaved mixed afforestation can effectively promote the growth of Castanopsis hystrix,and is a model of cultivation and afforestation of Castanopsis hystrix that is worthy of promotion.
