The benefits of winter irrigation in orchards
Winter irrigation of fruit trees can increase soil moisture content. Utilizing the latent heat released by trees and the heat of condensation of soil water can not only improve the cold resistance of fruit trees, ensure the safe wintering of fruit trees, but also accelerate the decomposition of soil organic fertilizers and increase soil fertility. During the winter irrigation time, the fruits were harvested before the soil was frozen. However, the average temperature of 5°C in the 5cm soil layer and the temperature of 3°C was the best period. It is advisable that the amount of water poured into the ground be the same as the amount of water on the day after irrigation. The water seeps into the root distribution layer, ie, the young trees penetrate to 20cm to 60cm, and adult trees seep to 70cm to 100cm. The soil moisture is maintained at 60% to 80% of the maximum water holding capacity in the field. Water irrigation methods Orchards with adequate water sources and well-watering equipment can be used for flood irrigation or ring-shaped furrow irrigation; in orchards with poor water sources and poor conditions, discoid soil can be re-irrigated around the perimeter of the tree canopy; orchards with drip irrigation and sprinkler irrigation conditions. Drip irrigation and sprinkler irrigation works best. China Agricultural Network Editor
