果树在系统发育中形成了对水分不同要求的生态类型,按照抗旱能力和需水量不同,可将果树分为以下三类:(1)抗旱力强的桃、扁桃、杏、石榴、枣、无花果、核桃、凤梨。(2)抗旱力中等的苹果、梨、柿、樱桃、李、梅、柑桔。(3)抗旱力弱的香蕉、枇杷、杨梅。水分过多或不足,不仅影响当年果树产量与品质,也影响来年果树的结果状态,甚至还会影响到果树的寿命,缩短结果年限。 1.灌水时间 果树灌水,应在果树未受到缺水影响以前就进行,若果树显露出缺水状态时再灌水,将对果树的生长和结果造成不可弥
Fruit trees in the phylogeny of the formation of ecological requirements of different water requirements, in accordance with the ability of drought and water demand can be divided into the following three categories of fruit trees: (1) drought-resistant peach, almond, apricot, pomegranate, jujube, fig Walnut, pineapple. (2) medium drought-resistant apple, pear, persimmon, cherry, plum, plum, orange. (3) drought-resistant banana, loquat, bayberry. Too much water or insufficient water not only affects the yield and quality of the fruit trees of that year, but also affects the fruit status of the fruit trees of the coming year. It even affects the life span of fruit trees and shortens the life span of the fruit trees. 1. Irrigation time Fruit trees should be irrigated before fruit trees are affected by water scarcity. If the trees are exposed to water shortages, irrigation will result in immeasurable growth and results of the fruit trees
