促进苹果幼树早成花、多结果,进而控制树体大小,是苹果密植丰产栽培的重要环节之一.为了探讨催花、增产的简易有效技术途径,自1977年以来,我站与有关单位协作,进行了乙烯利在苹果幼(旺)树上的应用研究.结果如下.一、材料和方法供试品种有青香蕉、红香蕉、国光、印度等.树龄三至十年生,多数为尚未结果或结果很少的幼(旺)树.供试植株生长发育基本一致,栽培管理一般.单株小区,重复3次.
To promote the early flowering of young apple trees, fruitful results, and then control the size of the tree, it is one of the most important steps in the cultivation of densely-planted apple trees.In order to explore a simple and effective technical approach to promote flower and increase yield, since 1977, The results of which are as follows: I. Materials and methods The tested cultivars were green banana, red banana, Guoguang, India, etc. The age of three to ten years old, most of them were not yet Results or results rarely young (Wang) trees for the test plant growth and development are basically the same, cultivation and management in general.
