干旱地区杨树深栽造林技术的研究推广

STUDIES AND POPULARIZATION OF THE TECHNIQUE OF AFFORESTATION DEEPLY PLANTING THE POPLAR IN THE DR Y AREA

我国北方地区干旱少雨,地表水源缺乏,造林成活率很低,重复造林使生产蒙受巨大损失。但许多地方蕴藏着丰富的地下水,通过深栽造林,可提高造林成活率,获得良好生产效益和经济效益。

In the northern part of our country where the climate is dry and rainless, the afforesting survival rate is very low If repeat afforesta-tion, it enable production sustain a loss. But many places are rich in und?erground water, through deeply plant afforestation the afforesting surveval rate can increase, the good productive and economical benefit will be ach?ieved.
