沙黄松人工幼林生长特点调查研究

对沙黄松人工幼林的林分特征与结构、年生长规律、幼林生长进程以及造林效果进行了调查分析。结果表明：沙黄松人工幼林与马尾松同龄林相比，具有生长快、产量高、林分生长整齐、林分结构较稳定、形质性状优良的特点，沙黄松人工造林效果较好，可以在适宜地区推广。

Investigations on the Growth Features of Young Plantations of Pinus massoniana Var.Shaxianeses

In this paper，the investigations were made on the stand characteristics，stand structure，annualgrowth law，growth process and afforestation effect of young plantations of Pinus massoniana var．shaxiane-ses.The results indicate that the young plantations of P.m. var.shaxiaarses possess the features of fastgrowth，high yield，tidy stand growth，relatively stable stand structure and fine quality，as compared withthe same－age forests of P. massoniana.Its artificial afforestation effect is satisfactory and therefore it can bepopularized in suitable areas.
