随着育种技术的进展,极早熟桃(如四月红桃,五月脆桃)和极晚桃(如雪桃、圣桃、冬桃)相继出现,这对延长桃果市场供应期、提高桃农经济效益创造了有利条件。然而,在实际栽培中早熟桃落叶早、花芽多,产果量大而易引起树势早衰。晚熟与极晚熟桃果生长前期消耗养分少,树体营养丰富而生长过旺,导致落果较严重,给果农栽培管理 With the progress of breeding technology, extremely mature peaches (such as April peach, peach peach in May) and very late peach (snow peach, peach, winter peach) appear one after another, which will prolong peach market supply period and enhance peach Agricultural economic benefits have created favorable conditions. However, in the actual cultivation of early peach leaves deciduous early, flower buds, fruit yield large and easy to cause premature decay. Late maturity and very late peach fruit growth early consumption of less nutrients, nutrient rich tree growth over, leading to more serious fruit drop, to the farmers cultivation and management
