桃树座果量(除特殊年份外)在一般情况下都高,但为了提高果实品质,竞争市场,必须进行疏果,确定留果量。1.疏、定果时期疏果一般在落花后2周内进行。授粉充分,可早疏;气温低、开花不整齐,则晚疏;成年树早疏,幼年树晚疏;座果好的品种早疏,座果不良的品种晚疏;大年树早疏,小年树晚疏。定果在花后1个月内(硬核期前)进行。定果量主要看当时枝、叶生长 Peach fruit size (except for special years) are generally high, but in order to improve the quality of fruit, the market competition, we must conduct fruit thinning, to determine the amount of fruit retention. 1. Sparse, fruiting period of fruit thinning generally fall within 2 weeks after the flower. Pollination is sufficient, early sparse; low temperature, irregular flowering, then sparse; early sparse adult tree, juvenile trees late sparse; Small tree late sparse. Fruit fruiting within 1 month after anthesis (hard stage). The amount of fruit mainly depends on the time branches, leaves grow
