The nature of the kiwi planting soil is different, so the water requirement is different. It can be judged according to the maximum water holding capacity in the field (water retention capacity is small, the loam is centered, and the clay is the largest). Generally speaking, when the water holding capacity of the field from sand to clay is between 25% and 35%, the soil controlled by hand will be somewhat dry; when the maximum water holding capacity of the field is between 60% and 80%, the moisture controlled by hand can be dispersed, The water content in the soil is most suitable. The water holding capacity of the kiwi field soil is below 50%, and it is necessary to irrigate when the level is within the range of 20 cm. Sensory indicators: The kiwifruit planted on loam soil is controlled by hand, once controlled, it will be loose as soon as it is controlled; when the kiwifruit is planted on sticky soil, the soil will be controlled by hand, and there will be cracks when squeezing the soil after grasping. It means that the water holding capacity of the soil is about 50%, and the leaves not only wilt under noon exposure, but also wilt after strong light, which means that there is no water and irrigation is necessary.
