对已采收的果园,应立即进行施肥、喷药、修剪、清园等管理,以便提高果树的营养贮备和叶片的光合效能,增强抗寒能力,消灭害虫和病原,促进果树翌年早花早果。1.保护树体:果实采收后,要及时喷肥、喷药、喷施波尔多液或多菌灵一次,可有效的防治叶部病害,防止和减轻叶片早落;喷施1%的尿素液2～3次,以增加叶片对氮素的贮备,延缓叶片衰老,提高叶片的光合效能,增加树体有机
The orchard has been harvested, should immediately fertilization, spraying, pruning, clearing garden and other management, in order to improve the nutritional reserves of fruit trees and leaves of photosynthetic efficiency, enhance the ability of cold, eliminate pests and pathogens, and promote the early flowering fruit trees the following year fruit. 1. Protection of the tree body: after the fruit is harvested, it is necessary to timely spray fertilizer, spraying, spraying Bordeaux mixture or carbendazim once, which can effectively prevent and cure leaf diseases and prevent and reduce leaf fall; spray 1% urea Liquid 2 or 3 times to increase the leaf nitrogen reserves, delay leaf senescence, improve leaf photosynthetic efficiency, increase the organic tree
