栽植密度对黄菠萝生长的影响

摘要

通过对不同密度黄菠萝生长量的调查研究,认为栽植密度为789株/hm2 和1 955株/hm2 的林分,林木胸径、树高、材积3种生长量指标均明显高于栽植密度为10 000株/hm2 的对照林分. 同时,栽植密度为789株/hm2的林分,林木胸径、材积生长也明显优于1 955株/hm2 的林分. 栽植密度为10 000株/hm2 的对照林分林木生长最差. 在人工造林中宜采用789株/hm2 的造林密度.%Study on effect of different planting density on Phelodondron amurense growth.The results showed that the tree height,DBH and Volume of planting density 789/hm2 and planting density 1 955/hm2 were higher than contrast planting density 10 000/hm2.Tree height, DBH and Volume of planting density 789/hm2 were higher than planting density 1 955/hm2 .the planting density 10 000/hm2 were the worest .The best planting density of artificial afforestation is Planting Density 789/hm2 .
