Answer: Winter irrigation is also called frozen water. This watering is called frozen water for orchards. After the fruit tree enters the winter dormancy period, the nutrients begin to flow back from the tree body to the roots. In the years when there is little snow in winter, winter irrigation stores water in the soil, which increases the soil water content and prevents the occurrence of drought in winter and early spring. In addition, the increase in water content in the soil is conducive to the absorption of water and nutrients by the root system, thereby increasing the ability of fruit trees to resist freezing and drought, avoiding the drying of fruit trees due to physiological water loss, and ensuring the safe overwintering of fruit trees.
