苹果采收时间是否适宜,不仅对产量、品质和耐贮性有关,而且对花芽的深分化及翌年的坐果率和产量,也有很大影响。采收过早,果实发育不充分,不但降低产量、质量,耐贮性也明显下降;采收过晚,虽能提高当年产量和采收时的食用品质,但易诱发虎皮病、水心病等生理病害,特别是果实在树上通过呼吸跃变期后采收,果实的贮藏性显著下降,而且影响第二年的产量。 Appropriate harvest time apple, not only on the yield, quality and storability, but also on the deep differentiation of flower buds and the following year’s fruit setting rate and yield also have a great impact. Early harvest, fruit development is not sufficient, not only reduce the yield, quality, storage also significantly decreased; harvest too late, although can improve the current harvest and harvest edible quality, but easy to cause tiger disease, water heart disease And other physiological diseases, especially fruit trees in the respiratory transition period after harvest, fruit storage decreased significantly, but also affect the second year of production.
