板栗是重要的木本粮食树,在我省果树生产中占有一定地位。当前存在的主要问题是:栽培管理粗放,单株产量较低。掌握板栗的生物学特性,熟悉其周期各器官的生长发育动态,及其与外界环境条件的关系,是制定科学栽培管理技术的依据。为此,我们于1962—1963年进行了板栗不同器官生长特 Chestnut is an important woody food tree, which occupies a certain position in the production of fruit trees in our province. The current main problems are: extensive cultivation and management, lower yield per plant. Grasping the biological characteristics of chestnut, familiar with its cycle of growth and development of various organs and their relationship with the external environmental conditions, is to develop a scientific basis for the cultivation and management techniques. To this end, we conducted in 1962-1963, different organs of chestnut growth special
