摘　　要：对山区3种整地方式的土壤肥力和菌根化松树幼林生长的情况进行了连续4年的对比观察。结果表明:各种不同整地方式的土壤肥力变化不大,炼山不炼山的全垦、穴垦的林木高生长彼此存在差异。对于菌根的生长,以不炼山条垦为好,其次是不炼山全垦,但单位面积以不炼山穴垦用工量最少。所以在坡高为30°左右的山地,土壤肥力一般的山区,应选择不炼山条垦整地方式造林。The observation on the situation of soil fertility and growth of pine young forests with mycorhiza after three different methods of land preparation was made for four continuous years in the mountain regions.The results showed that the fertility was similar through different methods to prepare land;There were differences in high growth among the forests through total, strip and hole tillage after slash burning or slash no-burning.As for the growth of mycorhiza,the strip tillage after slash no-burning was the best,the next was the total tillage after slash burning.But the hole tillage after slash no-buming needed the least labour force of unit area.h is concluded that the strip tillage after slash no-burning should be adopted on the hillside with about 30°slope in the mountain region with medium soft fertility.
