要生产优质高档无污染苹果，果实套袋是重要的措施之一。但在生产中常出现套袋后成果率低的问题。为提高套袋苹果成果率，我们结合近几年生产实践，总结出了提高套袋苹果成果率的技术措施如下。 　　 　　一、套袋苹果成果率低的原因 　　1．病害防治不彻底。套袋前没有及时打 To produce high-quality high-grade non-polluting apples, fruit bagging is one of the important measures. However, there is often the problem of low result rate after bagging in production. In order to improve the yield of bagged apple, we combine the production practice in recent years, summed up the technical measures to improve the yield of bagged apple as follows. First, the reasons for low fruit bagging apple 1. Disease control is not complete. Did not play in time before bagging
