杜仲密植与常规栽培对比试验初报

Preliminary Report on Contrast Test of Dense Planting and Conventional Cultivation for Eucommia Ulmoides

摘要:

通过对1996年杜仲密植栽培的高生长、地径生长、胸径生长及树干性状进行随机重复抽样分析与杜仲常规造林进行比较，其结果表明：杜仲密植栽培高生长迅速，干形通直，分枝高而少，弯曲、下垂少。而常规栽培高生长缓慢，干形通常弯曲且多为下垂，分枝矮而多。地径和胸径略大于密植栽培。

Abstract:

Analysis of repetition sampling randomly and conventional afforestation of Eucommia ulmoides were carried out based on growth of height, ground diameter, DBH and tree trunk character of Eucommia ulmoides densely planted in 1996. The result showed that it grown fast, straight trunk shape, high branch and less, bend and less hanging. However, the height of the conventional planting grown slowly, bend and more hanging usually in trunk, more and short branch which the ground diameter and DBH were lightly bigger than the dense planted ones.
