摘要(Abstract)：

檫木在东南沿海地区常规造林成活率偏低,对檫木裸根苗进行截干造林试验,结果表明:造林前两年檫木截干与未截干造林在成活率和地径、树高、抽高等生长量指标除了在第二年树高差异为显著水平外,其他指标在年度、性状间均为极显著差异;截干造林明显提高檫木造林成活率,造林第一年成活率100%,第二年成活率98%,两年生时截干造林成活率比未截干造林提高30.15%;明显促进地径生长,地径年生长量29%以上;大幅度提高抽梢生长量,第一年增幅222.78%,第二年增幅94.49%,檫木截干造林在东南沿海地区效果明显,是值得推广的造林方法。
The survival rate of afforestation with typical Sassafras tzumu is relatively low in the southeast coastal area.In this study, the stem of dry-rooted seedlings of Sassafras tzumu were cut off and afforested. The results showed that:(1) After two years of afforestation, the stem-cutting treatment significantly affected the survival rate, ground diameter,tree height, and growth indicators. Furthermore, except that the difference of tree height in the second year is significant, other indicators were extremely significant in different years and characteristics.(2) The stem-cutting treatment significantly improved the survival rate of Sassafras tzumu, which was 100% in the first year and 98% in the second year. Compared with the afforestation without stem-cutting treatment, the survival rate of the afforestation with stem-cutting was increased by 30.15%.(3) The stem-cutting treatment obviously promoted the growth of ground diameter, and the annual growth of ground diameter was over 29%.(4) The stem-cutting treatment greatly increased the shoot growth, with an increase of 222.78% in the first year and 94.49% in the second year. The results indicated that the stem-cutting afforestation had obvious effect in southeast coastal areas, and it was a promising afforestation method worth popularizing.
