提高香榧造林成活率的关键技术研究

针对香榧发展慢、造林成活率低的实际问题,结合对其生长习性的观察,在分析以往造林成功经验和失败教训的基础上,进行技术集成并开展有针对性的造林试验.从中发现合理选择香榧苗木类型、起苗和造林时做好苗木保护措施、苗期遮阴、苗木浅栽并加强幼林管理是提高其造林成活率的关键技术.

To Improve the Survival Rate of Aforestation of Chinese Torreya of Key Technology Research

Torreya grandis naturally grows slowly and the survival rate of forestation is low,which prevents this tree species from being widely grown.Based on a detailed investigation into the previous forestation and the experience with both successful and failed results,a set of comprehensive techniques was integrated and particu-lar forestation experiments were carried out.It was demonstrated that selecting suitable seedlings,applying prop-er protection while lifting and transplanting the seedlings,shallow soil loosening,right shading in seedling一pe-rind,and intensive tending were the key techniques to promote the survival rate of forestation.
