Management measures of soil and fertilizer in kiwifruit orchard

1 fertilization:
(1) Fertilize young trees. Young trees are designated for 1 to 3 years after planting. After planting, the kiwi saplings cultivate an ideal tree-shaped skeleton through reasonable fertilizer and water management. Because the saplings are shallow and tender, they do not absorb much fertilizer. The kiwifruit is of the fleshy root system. When fertilizing, the concentration should be strictly controlled to avoid root damage. For acid-stained soil, apply a proper amount of lime powder, 30 to 50 kg per mu. Apply base fertilizer once a year and topdressing 4 to 6 times. The base fertilizer is applied during the expansion of the winter season. Each plant is stalked with 2.5 kg of peanut bran, 30 kg of beef, pig fat or soil fertilizer, mixed with the soil. Topdressing should be done in a thin application. It can be applied by urea or compound fertilizer or ditch. The fertilizer is applied outside the canopy drip line and cannot be directly contacted with the root system. It can also be applied to water by decomposing excrement. Topdressing begins in late February (new planting trees from early April to late August), with an interval of about 25 days.
(2) The result tree is fertilized. After 3 years of planting, kiwifruit began to enter the fruiting period, and the tree shape was basically formed. The result was stable and the management was basically stable. Fertilization time, fertilization amount and fertilization method were determined according to the nutrients required for different growth stages of kiwifruit throughout the year. Generally, fertilize about 4 times a year.
1 autumn and winter fertilizer (9 to 12 months): before and after fruit picking to the deciduous leaves, with soil fertilizer combined with compound fertilizer for ditch application or expansion of the application.
2 budding fertilizer (late February to early March): compound fertilizer and urea before germination.
3 Xie Huafei (from mid-April to early May): Apply compound fertilizer and urea once before and after Xiehua.
4 strong fruit fertilizer (in mid-June): 1 compound fertilizer based on phosphate fertilizer.
2 moisture management:
Kiwifruit requires a large amount of water, and the roots are not resistant to water stains and have a shallow distribution. Rainy season should pay attention to drainage, high temperature and dry season should be timely irrigation, especially in June-August.
3 soil management:
The roots of kiwifruit are shallow, and weeding and weeding should avoid damage to the roots. The young orchard is combined with autumn and winter fertilization for deep renovation, and intercropping between legumes such as soybeans and mung beans.
