为提高半干旱地区石质山地植苗造林成效,进行栽植穴中增添适量的野生灌草作为隔离层的试验,结果表明：在栽植穴土壤当中增添6 cm左右灌草隔离层,用量为鲜质量2.2～2.3 kg/株、风干质量0.60～0.75 kg/株,上层覆盖暄土厚度3 cm左右的造林技术,抵御旱害效果显著,平均成活率和保存率可达85%以上。该项造林新技术不受季节限制,适用于容器大苗和裸根苗造林。

The wild shrub and grass were put into the planting holes in order to improve the afforestatin effect,results showed that put 6 cm shrub-grass isolation layer into the planting holes,that fresh quantity was 2.2 - 2.3 kg/hole,or air drying quantity was 0.60 - 0.75 kg/hole, then covered with 3 cm loose earth.The technique has significant effect of resisting drought damage,the average survival rate and conservation rate were all above 85%.This new afforestation technique without seasonal restrictions can be applied in large container seedlings and naked root seedlings afforestation.
