确定苹果适宜负载量是个比较复杂的问题.因为单株产量高低常受自然条件、管理水平、砧穗组合等因素的影响,产量总是处于变化之中.但在一定条件下,果树只能有一定的负载能力.在苹果负载量方面,前人曾提出和应用了许多方法,但有些难于掌握和不便应用.为了探索简单、实用而又快速确定苹果负载量的方法,我们通过10年来科 Determining the appropriate loading of apples is a complex issue because yield per plant is often subject to change due to factors such as natural conditions, management level, combination of scion and head, etc. However, under certain conditions, A certain load capacity.In the apple load, many methods have been proposed and applied, but some are difficult to grasp and inconvenient to use.In order to explore a simple, practical and quick method to determine the amount of apple load, we passed 10 years
