什么是梨樹二次開花?

發布人:臨沂育果花粉發布時間:2016/12/22

梨樹開花什么什么情況?經過查閱,小編發現,梨樹二次開花是指一年內梨樹開兩次,一般在10月上旬開始就可以見到,嚴重的株開花率可達50%左右。梨樹二次開花,不僅大量消耗樹體養分,嚴重削弱樹勢,而且大量花芽提前萌發開花,嚴重影響第二年產量及品質,同時還會引發大量抽發秋梢、秋葉,影響樹體的安全越冬。育果梨花粉足彩APP排行榜為您介紹以下原因及預防方法。

一、發生原因:梨樹與其它果樹相比,較容易出現二次開花,原因歸納起來有以下幾個方面。

6、采果不當。高產年份掛果過多,不注意適當疏果,影響了枝梢的正常生長;采果時一次性全部采摘后破壞了樹體水分的代謝平衡,加上傷口多,失水嚴重,就會造成樹葉萎蔫,加速葉柄離層形成,從而提早落葉形成二次開花。

二、預防措施: 防止秋季梨樹二次開花關鍵措施是保葉,因此應從栽培管理上圍繞這一中心。
