林木种子对更新和育苗、更新后林木生长发育有直接影响,因此开展母树林的经营管理工作非常必要。大片的母树林经营工作,是一项新的工作。大兴安岭林区,在1958年大跃进的形势的鼓舞下,两年来很多林业局已划定母树林,有的林业局采取一些措施,这是良好的开端,但工作开展的不够广泛和深入。应当作到场场有母树林,加强母树林的经营管理。现就母树林的选定和经营管理工作提几点意见供参考。一、选定母树林划分固定采种区,建立种子基地,以达到有计划的供应优异种子。选定母树林的林分是非常重要的步骤。米丘林曾说过:不仅亲本的特性和品质的好坏遗传后代,人们施行的对植物有机体
Tree seeds have a direct impact on the regeneration and seedling raising, and the updated tree growth and development. Therefore, it is necessary to carry out the management of the parent tree forest. A large piece of parental forest management work is a new job. In the Greater Xing’an Mountains, inspired by the Great Leap Forward in 1958, many forestry agencies have delineated parent trees in the past two years and some forestry agencies have taken some measures. This is a good start but the work is not conducted extensively and in depth. It should be made of mother trees in the field and strengthen the management of the mother trees. Now on the selection of mother trees and management work to mention a few comments for reference.

The selection of the parent forest is a very important step. Michurin once said: Not only the quality and character of the parents of the genetic offspring, the implementation of the plant organisms
