果树冬灌也就是给果树灌冻水。果树冬灌既能促使树体放出潜热和土壤水凝结热,提高果树的抗寒能力,保证果树安全越冬;又能加快有机肥腐熟,有利于根系对矿物质的吸收,提高树体营养物质的积累,增加土壤含水量,预防春旱,提高来年果品质量和产量。冬灌技术是:1.冬灌时间。果树冬灌时间,以果实采收后到土壤封冻前为冬灌最佳时期。冬灌过早,气温还比 Fruit tree winter irrigation is to fruit trees shredded water. Fruit tree winter irrigation can not only promote the release of latent heat of the tree body and soil water condensation heat, improve cold hardiness of fruit trees to ensure the safety of fruit trees overwintering; but also to accelerate the decomposition of organic fertilizer is conducive to root absorption of minerals to improve the accumulation of tree nutrients , Increase soil water content, prevent spring drought and improve the quality and output of fruit products in the coming year. Winter irrigation technology is: 1. Winter irrigation time. Fruit trees winter irrigation time, the fruit harvest to the soil before freezing for winter irrigation the best period. Winter irrigation too early, the temperature is still higher than
