摘　　要：从生长量、生物量2个方面,研究容器苗和裸根苗2种不同育苗方式对苗木生长的影响,结果表明,2种育苗方式,其苗木的苗高、地径高径比差异显著,容器苗的高径比低于裸根苗,说明容器苗抗性高于裸根苗;容器苗根冠比显著高于裸根苗,有利于提高造林成活率。From the aspects of growth amount and biomass,the growth difference of seedlings under light seedlings and bare roots were studied.The results showed that the two seedlings were used.The seedling height and the heightdiameter ratio of the seedlings were significantly different.The height-diameter ratio of the container seedlings was lower than that of the bare root seedlings,indicating that the container seedlings had higher resistance than the bare roots.From the root-shoot ratio,the light-matrix container seedlings had a significant crown-to-crown ratio.Higher than bare root seedlings are conducive to increasing the survival rate of afforestation.
