一、水分管理土壤水分过多 ,使果实含水量增加 ,品质变劣 ,抗病能力下降 ,易发生心腐、炭疽等病害 ,因此在果实生长后期应适当控制灌水 ,防止雨后积水。二、光照管理树冠的通透性强 ,可增加苹果养分积累 ,促进苹果着色 ,提高果实品质 ,因此对郁闭树冠应疏除无用枝、徒长枝、细 First, the water management Soil moisture is too much, so that fruit moisture content increased, poor quality, resistance to decline, prone to heart rot, anthrax and other diseases, so the late fruit growth should be properly controlled irrigation to prevent water after rain.
