正常年秋分一過開始摘梨
，可是有些果園等不到這個節令

，樹上地下就有爛梨。據分析，爛梨的原因主要是蟲病所害。

1、病bing蟲chong防fang治zhi不bu可ke掉diao以yi輕qing心xin。梨li樹shu一yi般ban在zai清qing明ming節jie前qian後hou開kai花hua，秋qiu分fen節jie左zuo右you摘zhai梨li。花hua後hou管guan理li不bu能neng有you半ban點dian麻ma痹bi大da意yi。首shou先xian是shi防fang凍dong和he授shou粉fen認ren真zhen細xi致zhi還hai是shi敷fu衍yan了le事shi走zou過guo場chang，這zhe是shi能neng不bu能neng掛gua果guo的de關guan鍵jian。疏shu果guo套tao袋dai可ke以yi根gen據ju實shi際ji情qing況kuang進jin行xing選xuan擇ze，追zhui肥fei澆jiao水shui能neng量liang力li而er行xing
