随着育种技术的发展,极早熟桃(如四月红桃、五月脆桃)和极晚熟桃(如雪桃、圣桃、冬桃)相继出现,这为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;晚熟与极晚熟桃在果实生长前期消耗养分少,使树体营养丰富生长过旺,导致落果严重。为了克服以上弊端,
With the development of breeding technology, very early ripe peach (such as April peach, crisp peach in May) and very late ripe peach (such as snow peach, peach, winter peach) appear one after another, which will prolong peach market supply period and improve peach Agricultural economic benefits have created favorable conditions. However, in the actual cultivation of early peach leaves deciduous early, flower buds and large quantities of fruit yield easily lead to premature decay; late ripening and very late peach consumption of nutrients in early fruit growth less, so that the tree rich nutrient-rich growth, resulting in serious fruit drop . In order to overcome the above drawbacks,
