果树生产上一年结果甚多而另一年结果甚少的大小年循环结果,是一种影响果树产量、品质和抗寒抗病能力的不正常现象。很多果树生产者和科学工作者都在注意研究解决这一问题。生产实践证明,大小年结果,并不是果树不可避免的固有特性,而是完全可以通过加强培育管理,予以相对的克服。现根据我省各地生产情况,对引起果树大小年结果的原因与克服办法,提出以下商讨性意见,供参考。
The result of annual fruit production in the previous year is very large and the result of the other year is very small. The result is an abnormal phenomenon that affects the yield and quality of fruit trees and the resistance to cold and disease. Many fruit tree producers and scientists are paying attention to studying and solving this problem. Production practice has proved that the annual results are not the inevitable inherent characteristics of fruit trees, but can be overcome by strengthening their management. Now based on the production of our province all over the cause of the size of the annual results of fruit trees and overcome the reasons for the solution, put forward the following discussion for your reference.
