葡萄采收后的病虫害防治是一个重要环节,但经常被果农忽视,因为其一,果实采收后,树体需要养分来供应枝条老熟、花芽分化、根系生长和营养储备,保证安全越冬及第二年葡萄发芽到开花前的生长。这些养分主要靠叶片光合作用制造而成。所以,葡萄果实采收后,应尽可能地保留好葡萄叶片,延长光合作用时间,让叶片制造更多的营养,供给“看不见”的生长。其二,葡萄采收后,容易出现霜霉病、黑痘病、褐斑病、蛀食枝蔓的虫害、叶蝉等危害,如不防治或防治不力,不但会引 Pest control after grapes harvesting is an important link, but it is often neglected by fruit growers, because first, after the fruit is harvested, the tree needs nutrients to supply ripening branches, flower bud differentiation, root growth and nutrient reserve, to ensure safe wintering and The second year the grape sprouted to bloom before its growth. These nutrients are mainly made by leaf photosynthesis. Therefore, the grape fruit harvest, grape leaves should be retained as much as possible to extend the photosynthesis time for leaves to create more nutrition, supply “invisible ” growth. Second, the grape harvest, prone to downy mildew, anthracnose, brown spot disease, worm pest infestation, leafhoppers and other hazards, if not prevention or control ineffective, not only will lead
