摘要
按照立地条件的不同,采用随机抽样法对渭北黄土高原后沟作业区油松容器苗与裸根苗造林效果进行了调查和分析。结果表明:不同立地条件下,油松容器苗造林成活率、幼树树高生长量均高于裸根苗,而且,不同坡位间容器苗与裸根苗造林成活率存在不同差异。
According to different site conditions, container seedlings and bare-root seedlings of Pinus tabulaeformis Carr. planted on loess plateau of Weibei were randomly sampled for analysis of afforestation effect. The results showed that container seedlings are much better in survival and height growth during young age than bare-root seedlings under different site conditions. Slope positions presented differences of survival rate among container seedlings and bare-root seedlings.
