The purpose of kiwi winter irrigation is to obtain a good harvest in the following year. During mid-October to early December, according to local weather changes, kiwi trees should be irrigated before freezing. This irrigation is called overwintering water, because winter irrigation can increase soil temperature, protect the roots of the tree, prevent frostbite, and at the same time subsidize the condition to avoid drought in early spring. Determine whether kiwi needs water. When the maximum water holding capacity in the kiwi field is 60% to 80%, the moisture content in the soil is the most suitable when the humidity is controlled by hand and can be spread out. Maintaining the maximum water holding capacity in the field during the dormant period is 80%. . Water-saving irrigation is mainly used to change large-area flood irrigation to local irrigation, such as flood irrigation, furrow irrigation, hole irrigation, and tree tray irrigation. Water infiltrates into the soil from the furrows, furrows, bottoms and sides of the furrows, without destroying the soil aggregate structure, and the root range is not affected In addition, the soil is evenly moistened, no water will accumulate, and the roots will not rot due to water accumulation. For ridge planting, water can be poured into the middle of the ridge, so that the roots are in a long-term stable humidity and good ventilation environment, which is good for growth, does not damage the young and new roots, and will not rot the roots due to accumulated water.
