摘　　要：为提高柔毛油杉苗木质量,对柔毛油杉播种实生苗切根移栽进行了对比试验,同时采用不同基质配比培育苗木进行了比较。结果表明:切根可显著提高柔毛油杉苗苗高,地径生长影响不明显;基质为60%松林土+40%泥炭土、60%松林土+40%腐熟木屑育苗效果好。In order to improve the quality of the seeding growth of keteleeriapubesens,the seedling transplanting of the seedlings of keteleeriapubesens was carried out. The seedlings were cultivated with different substrates compositions. The result showed that the height growth of keteleeriapubesens could be increased evidently by transplanted, but the effect of ground diameter growth was not obvious. The seeding grew better on substrates 60 % pine soil ＋ 40% pine bran and 60%pine soil＋ 40%rotten sawdust.
