苹果套袋栽培后期管理内容摘要:
2、期以前约天时开始,金冠苹果在采收前可不必除袋。 除袋具体时间:对于双层袋,外层袋和内层袋除袋的具体时间,均宜在上午时以后至下午时之前进行。 对于单层袋,宜于上午时后至下午时前将单层袋纵向撕开数条,约天后再除去袋子。 三、摘叶摘除影响果实受光的叶片,能增加着色指数以上。 一般从采收前一个月开始,分次进行。 第一次是摘除果梗部位直接影响果实着色的叶片,第次是摘除果实周围厘米的叶片,第次在采收前半月进行,摘除果实附近及影响到内膛果实受光的外围叶片。 四、转果一般在果实阳面着色后进行。 转果时,用右手托住果实,左手捏住果柄基部,把果实背阴面转向阳光照射的方向,必要时用透明胶带固定果实。 对于下垂果来说,因没有可使转过的果实固定的地方,因此一般不进行转果。 五、铺反光膜一般是在采前天左右进行,即摘完袋并进行第一次摘叶后进行。 必要时,可在果实着色期内,清除膛内徒长枝。 六、适时采收果实达到生理成熟度时,半月内可增加糖分,风味浓厚,果色鲜艳,且能增产,还可以增加耐贮运能力。 因此,套袋果的采收要比无袋果正常采收期延迟周,以增进果实的甜度和风味。 专利查询。苹果套袋栽培后期管理
