本研究在全国首次提出并通过５年多的试验研究表明：于杉木中、幼林中选优砍伐，挖蔸移栽建圃，是一项行之有效的促萌新技术，移栽成活率达９０％～１００％，当年平均单株产条量３０～４０枝，与传统的就地砍优促萌方法相比，具有建圃快、产条量高、便于管理、节省采条用工等明显优点；比较系统的解决了移蔸优树适宜年龄、最佳移蔸时间、营养枝留养、移植母株根系发育规律等一系列关键技术问题，特别在营养枝留养及其与根系发育和萌条产量之间关系方面有新的发现，使本项技术更加系统化和实用化，为杉木原种圃、采穗圃的管理提供科学依据。
This study was first put forward and passed more than five years of experimental study in the whole country. It shows that the best cutting and digging in the young and middle-aged Chinese fir plantations is a new and effective technology to promote the transplanting. % ~ 100%, when the average per plant yield of 30 to 40, compared with the traditional method of in situ cutting and promoting sprouting, with fast build nursery, high yield, ease of management, saving mining and other significant advantages ; A series of key technical problems, such as proper age of elm tree, optimum removal time, vegetative branch maintenance and root development rule of transplanted mother plant, were solved more systematically, especially in vegetative branch maintenance and root development The relationship between the production of new discoveries, so that the technology more systematic and practical, for the original seedling nursery fir, scion nursery management to provide a scientific basis.
