Kiwifruit planting technology: how to fertilize kiwifruit?

How to fertilize kiwifruit? Netizens with kiwifruit planting experience are also invited to help introduce in detail the fresh and tender quality, rich nutrition and delicious flavor of kiwifruit. The fruits that people like to eat, which have the effect of beauty and skin aging, are deeply loved by people of all ages. Therefore, the demand for kiwifruit is also increasing day by day. The farming network has sorted out the fertilization methods of kiwifruit in various periods, which are listed in detail below for netizens' reference. First, topdressing budding fertilizer in early spring: after soil thawing and sap flow in spring, the tree begins to move, and fertilization in this period is beneficial to sprouting and flowering and promoting new shoot growth. Sprouting fertilizer should be applied before sprouting of kiwifruit, mainly available nitrogen fertilizer (nitrogen fertilizer accounts for 1% of the total amount of nitrogen fertilizer in the whole year) combined with a small amount of phosphorus and potassium fertilizer. 4-year-old trees generally apply 10 kg of pure nitrogen, 4 kg of pure phosphorus and 4 kg of pure potassium per mu. Sprinkle or plant fertilizer in the whole garden, and then irrigate spring water 1 Mel twice. Second, topdressing to promote fruit fertilizer after flowering: 30-40 days after kiwifruit blooming is the period of rapid expansion of kiwifruit, at this stage, the fruit grows rapidly, the volume increases rapidly, and lack of fertilizer will hinder the expansion of rhesus monkeys. Fruit-promoting fertilizer should be applied 20 ~ 30 days after kiwifruit falling flower, mainly quick-acting compound fertilizer. Each 4-year-old kiwifruit tree can be treated with 0.25 kg potassium dihydrogen phosphate 0.3 kg. The whole garden was watered once after the application. 3. Topdressing strong fruit fertilizer in midsummer: in order to enrich kiwifruit inside, increase single fruit weight and improve quality, it is appropriate to apply phosphorus and potassium fertilizer once from June to July. In order to make up for the lack of nutrition during shoot growth in the later stage, available nitrogen fertilizer can also be sprayed on the leaves for 1-2 times. Foliar spraying calcium fertilizer at this stage can also enhance the storability of fruits. This fertilization should be based on foliar spraying, and 0.5% potassium dihydrogen phosphate, 0.3% urea solution and 0.5% calcium nitrate can be selected. Fourth, the basic application of overwintering fertilizer after fruit harvest: a lot of nutrients are lost in the leaves of kiwifruit after fruit harvest, and it is particularly important to supply tree nutrients at this time. 0.5% urea solution can be sprayed on the leaf surface before defoliation to increase leaf photosynthesis, promote the return of nutrients to roots and stems, and increase nutrient storage. In autumn, base fertilizer should be applied early, mainly organic fertilizer such as manure, retting, compost, barnyard manure, cake fertilizer, and mixed with some available fertilizers such as calcium superphosphate, ammonium nitrate and so on. Generally, 4-year-old trees should apply 30kg organic fertilizer 20ml, plus 0.25kg calcium superphosphate and ammonium nitrate. It can be sprinkled in the whole garden or ditched. Irrigate once after application. Methods of kiwifruit seedling cultivation methods for prevention and control of kiwifruit canker
