Winter irrigation of fruit trees can increase soil water content, and use the latent heat released by trees and soil water condensation heat, which can not only improve the cold resistance of fruit trees, but also ensure the safe wintering of fruit trees, accelerate the decomposition of soil organic fertilizers, and improve soil fertility.
Winter irrigation is carried out after fruit harvesting until the soil is frozen, but the average temperature is 5 °C and the temperature is 3 °C in the 5 cm soil layer.
The amount of irrigation should be such that all the water can penetrate into the ground on the day after irrigation. The water seeps into the root distribution layer, that is, the young tree infiltrates to 20 cm to 60 cm, the adult tree infiltrates to 70 cm to 100 cm, and the soil moisture maintains 60% to 80% of the large water holding capacity in the field.
In the orchard with sufficient water source and sufficient water irrigation, the irrigation method can be adopted by the irrigation or circular ditch; in the orchard with insufficient water source and poor condition, the disc-shaped soil can be re-irrigated around the canopy; the orchard with drip irrigation and sprinkler irrigation should adopt drip irrigation. And the sprinkler effect is good.
