3个珍贵阔叶树种大树移栽效果评价

Effect Evaluation of Transplanting Three Precious Deciduous Tree Species

以格木、柚木和降香黄檀3个珍贵阔叶树种中幼林的间伐木为材料开展大树移栽,依据移栽后的成活率、生长表现、观赏性以及健康状况评价其移栽效果。结果表明:3个树种的大树移栽成活率均在98%以上,移栽3年后所有林木均生长良好,但格木和降香黄檀的冠幅较柚木舒展,其园林绿化效果明显优于柚木。

The thinned trees of middle and young forest in Erythrophloeum fordii,Tectona grandis and Dalbergia odorifera were used as experiment materials to evaluate the effect of big tree transplantation.The survival rate of transplanting,growth performance,enjoyment and health status were studied,respectively.The results showed the survival rate of three species were more than ninety-eight percent and all trees grew well after three years of transplanting.The landscaping effects of Erythrophloeum fordii and Dalbergia odorifera were better than Tectona grandis because of their good crown width.
