机耕整地营造赤桉林效果试验初报

Preliminary Experimental Report on Effect of Building Eucalyptus camaldulensis Forests by Tractor-ploughing to Prepare Ground

2001年在吉州区钓源等丘陵岗地上实施机耕撩壕整地栽植赤桉,结果表明:机耕撩壕整地比人工整地的幼树高、胸径、根系生长平均净增率分别高出27.9%、12.9%、58.3%,且造林工程花时少、进度快、成本低、效果显著。

By means of tractor-ploughing ground preparation was made in planting Eucalyptus camaldulensis in Diaoyuan and other hills of Jizhou district in2001.The results show that the average net increasing percentage of the young trees' height,the diameter and the roots were27.9%,12.9%and58.3%more than by using manual operation,and the method has many advantages,such as the less time ,the lower cost,and the better effect.
