摘　　要：为解决辽西北干旱半干旱石质山区造林成活率和保存率低的问题,选取抗旱能力较强的侧柏为供试树种,采用鱼鳞坑整地方式,分别采用常规植苗造林、覆膜造林及客土袋造林方法进行造林试验,当年入冬前调查成活率,3年后调查保存率,并对其进行统计分析。结果表明:应用客土袋造林方法林木成活率和保存率显著高于其他2种方法,确定客土袋造林方法为最适合石质山地的造林技术。In order to solve the problem of low survival rate preservation rate in arid and semi-arid mountainous areas in northwestern Liaoning Province,choosing Platycladus orientalis,which was resistant to drought,adopting the fish-scale land preparation,afforestation experiments were conducted by using the method of seedling planting,plastic-flim-mulching planting container seedlings.The survival rate of trees were counted before the very year of afforestation before winter;the survival rate and the preservation rate of the trees were analyzed.Result shows that survival rate of the trees by container seedlings is higher than that of two methods;it is determined that planting method of container seedlings is optimal techniques for afforestation in rocky mountainous areas.
