In order to achieve a good harvest in the following year, the kiwifruit winter irrigation should be conducted during the period from mid-October to early December, according to the local weather changes, and winter irrigation should be performed on the kiwifruit trees before freezing. This irrigation is called wintering water, because winter irrigation can increase the soil temperature, protect the roots of trees, prevent frostbite, and at the same time, it can also subsidize the public opinion and avoid the drought in early spring.
Judgment on whether kiwifruit requires water The maximum water holding capacity of kiwifruit in the field is between 60% and 80%. When the moisture is controlled by hand, the water content in the soil is most suitable. In the dormant period, the maximum water holding capacity in the field is kept at 80%, which is favorable for wintering and antifreeze. .
Mainly to reduce water-saving irrigation to flood irrigation to local irrigation, such as flood irrigation, furrow irrigation, hole irrigation, tree tray irrigation, water from the earthworm, ditch, hole bottom and side into the soil, without destroying the soil aggregate structure, root range breathing Impact; In addition, the soil is evenly moist and there is no accumulation of water, and it will not be rotted due to accumulated water. For the ridge planting, the water can be poured into the middle of the ridge so that the root is in a long-term stable humidity and good ventilation environment. It is beneficial to growth without damaging the young roots and rot.
