火炬松工业原料林经营模式研究

Study of Cultivation Patterns of Industrial Raw Material Forest of Loblolly Pine

对21年生的火炬松生长过程进行了研究,结果表明:火炬松胸径、树高前期速生,数量成熟期早,可作为短周期工业原料林培育,并在此基础上提出火炬松工业原料林的两种经营模式。

This article studies the growth process of loblolly pine at the age of 21. The results indicate that the diameter at breast height （DBH） and height of the loblolly pine grow rapidly in earlier stage, therefore, it can be cultivated as a short- cycle industrial raw material. And based on the study, the article proposes two kinds of cultivation patterns of loblolly pine industrial raw material forest.
