南方红豆杉实生苗和扦插苗定植后幼树生长量比较

Comparison of sapling growth of seedling and cuttage seedling of Taxus chinensis

对南方红豆杉实生苗、顶枝扦插苗和侧枝扦插苗定植3.5年后幼树的生长量(树高、地径和侧枝发枝数)进行观测与分析。结果表明:定植3.5年后幼树的树高、地径和侧枝发枝数在3个处理间均存在极显著差异。树高表现较好的处理是侧枝扦插苗,其次是实生苗,较差的是顶枝扦插苗;地径和侧枝发枝数生长表现较好的均是实生苗,其次是顶枝扦插苗,较差的是侧枝扦插苗。

With 42 months of Taxus chinensis（ seedlings,top branch cuttings and collateral branch cuttings） container seedlings planting,the growth（ tree height,ground diameter and number of collateral branching） of Taxus chinensis was studied. The results showed that,there were very significant differences in height,ground diameter and the number of collateral branching among three treatments. The tree height growth of collateral branch cuttings had better performance,followed by the seedlings and top branch cuttings. The ground diameter and number of collateral branching growth of seedlings had better performance,followed by the top branch cuttings and collateral branch cuttings.
