一、果树冬灌好处 1.果树冬灌,既能促进树体放出潜热和土壤水的凝结热,提高果树的抗旱抗寒能力,能保证果树安全越冬。 2.果树冬灌,能加快有机肥腐热,有利于根系对矿物质的吸收,提高树体营养物质的积累,加强土壤的含水量,防预春旱。 二、果树冬灌方法 1.冬灌时间。果树的冬灌时间,以果实采收后到土壤封冻前为冬灌适合期。冬灌过早,气温还比较高,蒸发量大,不利于蓄水保墒,降低了果树的抗寒防冻能力;过晚,气温偏低,土壤板结,水分渗不下去,积水冻结,树根系易遭受冻寒。果树冬灌的时间一般以5 First, the fruit winter irrigation advantages 1. Fruit tree winter irrigation, both to promote the release of latent heat of trees and soil water condensation heat, improve drought resistance of fruit trees cold ability to ensure the safety of fruit trees wintering. 2. Fruit trees winter irrigation, can accelerate the rot of organic fertilizer, is conducive to root absorption of minerals to improve the accumulation of tree nutrients to enhance soil moisture, prevent pre-drought. Second, fruit winter irrigation methods 1. Winter irrigation time. Winter fruit irrigation time, fruit harvest to the soil before freezing for winter irrigation fit period. Early winter irrigation, the temperature is still relatively high, the evaporation is large, is not conducive to water storage and conservation, reducing the ability of cold and frost resistant fruit trees; too late, the temperature is low, the soil compaction, water seepage, stagnant water, easy root system Suffer cold and cold. Winter fruit irrigation time is generally 5
