桃、李、樱桃、梨、苹果等果树,在开花期猛浇水会引起大量落花,严重时甚至会全树落光。这是因为骤然大量灌水后,土温也随之急剧降低,根系活力就随着降低,反而导致水分更加不足,加重了花朵缺水而脱落;同时由于根系的吸收能力降低,土壤里溶解在水中的养分不能及时吸收,导致输送到 Peach, plum, cherry, pear, apple and other fruit trees, fierce watering at flowering will cause a large number of falling flowers, even in full grazing when the light falls. This is because after a sudden large amount of irrigation, soil temperature will also be dramatically reduced, along with root activity decreased, but lead to more inadequate water, increased flower water loss and off; the same time as the root absorption capacity is reduced, the soil dissolved in water The nutrients can not be absorbed in time, resulting in delivery to
