杨树秋季深栽造林的效果分析

Effect Analysis on Tree Deep Planting of Poplar in Autumn

文章根据凤城地区的特点,在杨树速生丰产林培育方面,采用了根桩苗深栽技术,试验了不同截干根桩苗深栽对造林成活率、生根量、生长量的影响。试验结果说明,不同深栽,对当年造林成活率没有明显影响,但对生根数量、胸径生长量、叶面积指数有明显影响,深栽能明显提高杨树生长量。

The paper disscused that deep planting of various cut stump root seedling effects on the afforestation survival rate,the root number,growth in Fengcheng region.The experimental results demonstrated that the various deep planting had no significant influence on the afforestation survival rate in current year,which had zignificant influence on the number of rooting,DBH increment,leaf area index.Therefore,the growth of poplar improved obviously by deep planting.
