香椿芽矮林密植密度的研究

Studies on Planting Density of Bud-used Toona sinensis Low Forest

从早期经济效益考虑，香椿芽矮林密植的初植密度，以每公顷6万株为宜，以后随着林龄的增长，逐年疏去自然枯死的植株和生长衰弱、濒临死亡的植株，使每公顷矮林最终保持在1．5～2．25万株。如果一开始就要建立一个较稳定的矮化密植林，初植密度以每公顷1．5万株为宜。密植林的栽植，以每穴栽1株为好。

The initial density of bud-used Toona sinensis low forest should keep at 60, 000 plants per hectare, considering early economic benefits. With the increase of forest age, the dead plants and weak-growth plant were fell and final density kept at 15, 000~20, 000 plants per hectare. If a stable forest was constructed from beginning on, density of 15, 000 plants per hectare was suitable.
