合理的整形修剪应保持树形适当高大。过去桃树生产中多采用杯状形整形修剪,以短截修剪为主,目的是想多发出长果枝,然而适得其反,特别是密植桃园若连年短截重剪,将会导致生长过旺,树冠郁闭,花芽质量不高,果实品质及产量下降,商品率降低等不良影响,在生产中应尽快改进。西安市未央区的万亩良种桃生产基地,改传统的短截为主为疏剪为主,对于过密枝、病虫枝、无用枝、细弱枝及干枯枝采用疏去而不是短截,以果压枝,缓和生长势,促发健壮枝条。这样,既可促使
Reasonable plastic pruning should keep the tree tall and appropriate. Peach production in the past to use more cup-shaped plastic trim to pruning the main short cut, the purpose is to send more long branches, but counterproductive, especially in densely-packed Taoyuan perennial cut short cut, will lead to over-growth, crown Candelabrum, flower bud quality is not high, fruit quality and yield decline, commodity rate and other adverse effects, in production should be improved as soon as possible. Weiyang District of Xi’an mu seed production base, to change the traditional short stubborn sparse shear-based, for the dense branches, pest branches, useless branches, thin branches and dry branches to use sparse instead of short cut, If the pressure branches, ease the growth potential, to promote robust branches. In this way, can promote
