秋季是果园后期田间管理的关键时期。果实采收后,给果树施基肥效果相当好,数量和质量相同的肥料,秋施较春冬施用能提高坐果率8%—10%,提高产量10%—15%。将果园需肥量的80%放在秋季(9—10月)一次性施入,其增产增优效果非常明显。果树秋季施肥要掌握五要点:施肥时间:一般中晚熟品种在采果前后进行即可,原则是宜早不宜晚,此时气温高、雨量多,基肥有充足的时间分解,叶片功能尚未衰退,有较强的光合功能,养分回流到根中,正值果树根 Autumn is the critical period for field management in the late orchard. Fruit harvest, to the fruit tree fertilizer is very good, the same amount and quality of fertilizer, autumn application of spring than winter application can improve fruit setting rate of 8% -10%, increase the yield of 10% -15%. 80% of the amount of fertilizer needed in the orchard in the fall (September-October) a one-time application, the effect of its yield increase and increase is very obvious. Fruit tree autumn fertilizer to master the five main points: Fertilization time: generally late maturing varieties can be carried out before and after fruit picking, the principle is appropriate sooner rather than later, when the temperature is high, rainfall, basal fertilizer has sufficient time to decompose, leaf function has not declined, Have a strong photosynthetic function, nutrients back to the root, is the root of fruit trees
