摘　　要：对切根苗、容器苗、生根粉和根宝溶液浸根苗造林的单因素试验及不同整地、覆土方式、栽植时间、地面覆盖的多因素造林试验的效果进行研究，结果表明，采用切根苗、容器苗造林能明显提高造林成活率，达８５％以上。生根粉和根宝溶液浸根造林亦能提高造林成活率。采用不同的整地方式、覆土方式、栽植时间和地面覆盖措施的组合，对提高造林成活率、保存率和苗木生长的作用也不一致。The effect of planting experiment with container seedling,root undercuting seedling,root soaking seedling in promoter and different combination by means of site preparation,soil cover,planting time and the ground covering measure is analysed. Results show that the planting survival rate can be evidently raised with container seedling and root undercuting seedling, it has reached above the eighty_five percent.The planting with root soaking seedling has the same effect too.The survival rate,preservation rate and seedling growth are different with different combination by means of site prepartion,soil cover,planting time and the ground covering measures.

关 键 词：人工造林 成活率 保存率 山地造林
