对低产阔叶林实行带状伐开,在伐开带上栽植红松后,红松保存率及生长情况差异很大。为使带状改造的低产阔叶林栽植红松后,均能达到理想目的,本文就这几方面作了一些调查研究,试图探讨其中规律,以对解决生产急需有所裨益。一、不同宽度带上的红松生长情况(一)试验地概况试验地位于长白山,系北端的镜泊湖东岸江山娇林场境内,试验地年平均气温2°～4℃,最高气温37.9℃,最低气温—43℃,年降雨量500～700毫米.
The low-yielding broad-leaved forest is banded open, and the Korean pine is planted in the open zone. The preservation rate and growth of Korean pine are very different. In order to make the belt-shaped low-yield broad-leaved forest planted with Korean pine, can achieve the desired purpose, this paper made some investigations on these aspects, trying to explore the law, in order to solve the urgent need of production benefit. I. Growth of Pinus koraiensis at different widths (1) Overview of the experimental site The experimental site is located in Changbai Mountain, the Jiao Lin Field on the east coast of Jingbo Lake at the northern end. The annual average temperature is 2 ° -4 ° C and the maximum temperature is 37.9 ° C , The lowest temperature of -43 ℃, the annual rainfall 500 ~ 700 mm.
