果实采收后,许多果农只注意让果树“吃饱喝足”,而忽视为其“肌体”治虫防病。生产实践证明,念好治虫防病“三字经”是搞好果园冬季管理的主要措施之一。①清树下。果实采收后,树上所留叶片在继续通过叶绿素吸收光能,制造营养成份,而树下的枯枝、落叶,烂果、杂草则成了多种病虫的越冬场所。所以,在此期要组织人员将其彻底清理,把它们集中烧毁或在果园外高温积肥,这样既可消灭大量越冬病虫,又可增加有机肥的来源。 After the fruit is harvested, many fruit growers only pay attention to “satiate their fruit trees” and neglect their “body” pest control. Production practice has proved that read the pest control disease “Three Character Classic” is one of the main measures to improve orchard winter management. ① clear tree. After the fruit is harvested, the leaves on the tree continue to absorb the light energy through the chlorophyll to make nutrients, while the dead branches, deciduous leaves, rotten fruits and weeds under the tree become the overwintering places for various pests and diseases. Therefore, in the meantime, personnel should be organized to thoroughly cleanse them, concentrate them to burn or accumulate fertilizer outside the orchards at high temperatures, which can both eliminate a large number of overwintering pests and diseases and increase the source of organic fertilizer.
