为什么梨树应特别重视采后管理?

时间:13-04-20来源:果树网 作者:果树网 收藏

为什么梨树应特别重视采后管理?梨品种,如茌梨、鸭梨、长把梨、香水梨等,大都集中在9月中旬到10月上旬采收。采收后的9月下旬及10月,气温适宜,昼夜温差大,光照充足,对梨树根系生长和光合作用十分有利。抓好这一时期的管理,对于恢复树势,充实花芽非常有利,因此,是第二年丰产的基础。梨树落叶比苹果早,次年开花也比苹果早。枝叶生长早而集中,秋季采后这2个月的树势恢复营养积累显得更为重要。举凡丰产梨园,大都抓好此期管理。华北梨树栽培区多为秋旱,且秋收、小麦播种比较繁忙,梨园管理常被忽视。抓得早的,可以在9月中、下旬梨采收的同时进行灌、施肥、中耕,以此三项措施促进土壤微生物活动,促进根系生长,促进光合作用。再是对密植园、树冠密闭的单株进行间伐、疏枝,改善园、树冠光照,提高花芽质量。
