1, early spring treatment germination fertilizer. After the soil thaws in the spring and the sap flows, the trees begin to move. During this period, fertilization is conducive to budding and flowering and promotes the growth of new shoots. Pregerminating fertilizer should be applied before germination, and mainly available nitrogen fertilizer (nitrogen fertilizer accounts for 1/2-2/3 of the annual nitrogen fertilizer application), together with a small amount of phosphorus and potassium fertilizers. The 4-year-old tree generally uses 8-10 kg of pure nitrogen, 4 kg of pure phosphorus, and 4 kg of pure potassium. Take all garden measures or strains, and then spring water 1-2 times. 2, after flowering to promote fruit fertilizer. 30-40 days after flowering, the fruit of kiwifruit is rapidly expanding. At this stage, the fruit grows rapidly and the volume increases rapidly. The lack of fertilizer will hinder the enlargement of kiwi fruit. The fruit-promoting fertilizer should be applied within 20-30 days after flowering, mainly based on quick-effect compound fertilizer. Four-year-old trees can be applied with 0.25-0.3 kg of ammonium dihydrogen phosphate per plant. After the garden watered once. 3, Sheng Xia strong fruit fertilizer. In order to enrich the fruit inside, increase the single fruit weight and improve the quality, it is advisable to apply phosphorus and potash fertilizer once in June and July. In order to make up for the lack of nutrients in the growth of the shoots later, it is also possible to spray the available nitrogen fertilizer 1-2 times. During this period, foliar spray calcium fertilizer can also enhance the fruit's storability. The main application of this fertilizer is foliar spray. Potassium dihydrogen phosphate 0.5%, urea 0.3%-0.5%, and calcium nitrate 0.5% can be used as fertilizer. China Agricultural Network Editor
