Kiwifruit has different soil properties and different water requirements. It can be judged according to the maximum water holding capacity in the field (small water retention capacity, middle loam, and maximum clay content). Generally speaking, when the soil holding capacity of sand to clay is in the range of 25% to 35%, the soil will be somewhat dry by hand; when the maximum water holding capacity in the field is 60% to 80%, the moisture can be dispersed by hand, The most suitable soil moisture content. When the water holding capacity of kiwifruit field is below 50% and this level is within 20 cm, irrigation is needed. The kiwi planted on loam soil is controlled by hand and is controlled to form a mass and loosely spreads. Kiwifruit is grown on viscous soil, soil is controlled by hand, and there is a crack when the soil is squeezed after grasping, indicating soil water holding capacity. At about 50%, the blades will not only wilt under the noon sun, but will still wilt after strong light, indicating that there is water shortage and irrigation must be carried out. Fertilizers are formulated when properly used The top dressing ratio and the amount of strong fruit fertilizer fertilization principles are generally combined with medium-nitrogen, low-phosphorus, high-potash formula fertilizer and bio-organic fertilizer. At this time, reducing the amount of nitrogen fertilizer can make the kiwi fruit coloring on schedule, enhance the degree of lignification of the shoots, and promote safe wintering of the kiwifruit fruit trees. Appropriate application of potassium fertilizer can promote photosynthetic products. Namely: sugar transformation and transportation, increase fruit weight, promote fruit coloring, improve kiwifruit fruit quality and storability; At the same time, it can make branches thicker, accelerate the growth and maturation of shoots, enhance the antifreeze ability of kiwifruit tree body. There are two types of fertilization in the fertilization method: with the trunk as the center, fertilization is applied beyond the two-thirds projection of the kiwifruit canopy. Namely: 4 to 6 radial grooves, 30 cm in width and 15 to 20 cm in depth are drilled 60 to 80 centimeters away from the main pole, and fertilizer and soil are mixed and applied into the groove. Acupuncture points: In the kiwifruit crown from the main 80 to 100 cm outside the depth of 15 cm, 30 to 40 cm in diameter points, each side of each tree dig 2 to 3 points, the fertilizer applied. It is important to note that it is best not to spread or apply it, nor to mechanically plow. Youth Biotech CO,. Ltd. , https://www.youtherb.com
