日本落叶松在四川引种栽培的初步研究

报道了日本落叶松在四川20多年来的引种。栽培试验结果,证明引种是成功的。并进一步探讨了日本落叶松在四川各地的引种效果和树种生态适应性,提出了按四川自然地理分区和森林分区为基础的引种适生区划分标准。综合分析认为日本落叶松应成为四川省中山地带和高山峡谷区低海拔地带主要速生丰产造林树种之一。

A Preliminary Study of the Introduction of Japanese Larch into Sichuan

The results of more than 20 years of experiments are reported on the introduction of Japanese larch into Sichuan,showing that the introductron is a success. A further discussion is made on introduction effects of Japanese larch in many parts of Sichuan and its ecologic adaptability, and a suggestion is offered on the standards of the division of adaptive areas for introduction on the basis of the physical geographic regionalization and forest-division in Sichuan. As a result,Japanese larch should be one of main rapid-growth and high-yield species in mid-mountain zones and low-elevation zones in high mountains and canyons in Sichuan.
