Study on the Growth and Development Rhythms of 1-year-old Seedlings of Phoebe nanmu in Qimen County

本文对祁门滇楠1年生苗木育苗技术和苗期生长发育规律进行了系统研究,概括了滇楠苗木培育的四个时期,即出苗期、生长初期、速生期和苗木硬化期,总结了滇楠苗高、地径生长与环境条件、苗期人工集约管理的关系,旨在为滇楠苗木培育提供参考借鉴。

In this paper a systematic study was made on the seedling-raising techniques and growth and development rhythms of 1-year-old seedlings of Phoebe nanmu in Qimen County. 4 seedling-raising stages for Phoebe nanmu were generalized including the germination stage, early growth stage, fast-growing stage and seedling hardening stage. The relationship between the growth of the seedling height and basal diameter and the environmental conditions and artificial intensive management were summarized with the aim of providing seedling-raising reference of Phoebe nanmu for seedling-raising units.
