一、适期采收苹果采收的早晚对产量、品质、耐贮性等,都有很大影响,要根据果实发育状况和发育天数来确定。一般早熟品种在盛花后不超过100天采收,中熟品种为100～140天,晚熟品种140～150天。苹果采收后将其放到阴凉处进行预冷降温,尽快散掉果实所带的田间热,降低果实内的呼吸强度。二、药剂处理 1.苹果采收后,用6％的氯化钙溶液浸果,可提高苹果的硬度,降低生理病害发病率,好果率比对照可提高7～8％。 2.熏蒸:溴氯烷是熏蒸型广谱杀菌剂,有较好的杀菌和抑菌作用,对青霉菌,轮纹病菌、炭疽病菌均有 First, the appropriate harvest Apple harvest sooner or later on the yield, quality, storability, etc., have a great impact, according to the fruit development and development days to determine. Generally precocious varieties in full bloom after no more than 100 days harvest, medium maturing varieties for 100 to 140 days, late maturing varieties 140 to 150 days. After the apple harvest, put it in the cool place to precool the temperature, dissipate the field heat brought by the fruit as soon as possible and reduce the respiration intensity in the fruit. Second, the pharmaceutical treatment 1 apple harvest, 6% calcium chloride solution soaked fruit, apple can increase the hardness and reduce the incidence of physiological diseases, the good fruit rate can be increased by 7 to 8% compared with the control. Fumigation: Bromochlorine is a fumigation broad-spectrum bactericide, has good bactericidal and bacteriostatic effects on Penicillium, Ringworm, anthracnose bacteria have
