摘　　要：为解决干旱沙漠区因造林成活率低导致造林补植比重大、造林成本增加、影响林分质量提高等问题，就主要造林树种北沙柳机械打孔深栽抗旱造林技术进行了试验研究。结果表明，该技术具有造林成活率和劳动效率高、不需专门整地、简单实用等优点，其造林成活率较常规人工挖坑造林提高23．5％～42．8％；劳动效率是人工挖坑造林的2．67～3．78倍，适宜于在沙区灌木造林中推广使用。In order to solve the increase of planting cost and other problems during planting, the technology of drought - resistant afforestation of Salix psammophila by drilling with machine for deep - planting has been studied. The results show that the technology can raise the survival rate by 23.5% -42. 8% than the one of planting by arti- ficially digging and increase the labor efficiency by 2. 67 - 3.78 times than the one of planting by artificially dig- ging, which is suitable to popularize and apply in shrub afforestation in sandy area.
