目前梨树大多数实行密植栽培。但是在密植栽培中,如果不注意控冠或控冠不得法,往往造成树旺长、果园郁闭、结果晚、产量低等现象。据调查,采用以下综合措施控冠效果较好。1 适时控冠控冠开始的早晚是决定密植丰产的关键。过早易形成小老树,虽然结果早,但树冠小,产量低,维持结果年限短。控冠过晚,造成全园郁闭,不利成花,达不到丰产的目的。较适宜的控冠时间是在树冠将近
At present, most pear planting practice. However, in close planting, if you do not pay attention to crown control or illegal crown, often resulting in long trees, orchards closed, the results of late, low yield and so on. According to the survey, the following comprehensive measures to control the crown better. A timely crown crown control Crown sooner or later decide the key to planting density. Early formation of small trees premature, although the results early, but small crown, low yield, short duration of the results to maintain. Control crown too late, resulting in the whole park closed, unfavorable into flowers, achieve the purpose of high yield. The more suitable crown control time is near the crown
