在渭南市渭北黄土高原沟壑区进行了侧柏不同苗木类型、不同苗龄的造林效果对比试验研究，试验结果表明：在黄土高原干旱沟壑区造林宜选用定植培育1a、苗高0．8～1．0m的侧柏容器苗，较裸根苗可提高成活率37．3个百分点；选用定植培育2a、苗高1．8～2．0m的侧柏苗，要带直径和高度不小于20cm的土球，较不带土球苗提高成活率40个百分点；栽后截除苗木顶梢和茎干枝叶的一部分，较不截可提高栽植成活率26．8个百分点。

Comparison experiments of Platycladus orientalis were conducted with different rhizosphere and seedling ages in gully region of Weibei loess plateau in Weinan City .Result shows that it’s suitable to plant 1‐year‐old con‐tainer seedlings of Platycladus orientalis in gully region of Weibei loess plateau ,with the seedling height being 0 .8‐1 .0 m ,which can increase the survival rate by 37 .3% than that of bare‐rooted seedlings .Two‐year‐old Platycladus orientalis seedlings whose seedling height is from 1 .8 m to 2 .0 m were selected ,which can increase the survival rate by 40% than that without soil ball;the seedlings need earth whose diameter & height is not less than 20 cm ,and bandaging with non‐woven;after planting ,parts of branch tops and stems should be cut off ,which can increase the survival rate by 26 .8% than that without cutting .
