Kiwifruit planting technology: how to fertilize kiwifruit?

How to fertilize kiwifruit? Please give guidance for the cultivation of kiwifruit can refer to the following methods for fertilization: kiwifruit absorbs a large amount of inorganic nutrient elements, and after sprouting, in different periods such as leaf expansion, flowering and fruit development, the absorption of various nutrient elements is different. During the period from sprouting to fruit setting in spring, the accumulation of nitrogen, potassium and zinc in leaves was more than 80% of that in the whole year, and the demand for potassium was also high. (1) fertilization time: kiwifruit is generally fertilized once a year, topdressing 2-3 times. Base fertilizer: generally applied after harvest before defoliation. The time is from October to December. Mainly organic fertilizer, properly combined with phosphorus, potash fertilizer and available nitrogen fertilizer or human feces and urine, etc. Sprout fertilizer: from the end of February to the middle of March before sprouting. Sprouting fertilizer is mainly available nitrogen fertilizer to promote shoot growth and improve fruit rate. Strong fruit fertilizer: also known as summer fertilizer, carried out from May to July. Apply nitrogen fertilizer and potassium fertilizer, combined with extra-root topdressing, spray 1-2 potassium dihydrogen phosphate. This fertilizer is the most important fertilizer of the year. (2) the amount of fertilization: the amount of fertilization is directly related to tree age and annual yield. Generally, 56 1-year-old trees planted per mu apply 100g of urea, 125g of phosphate fertilizer and 345g of potash fertilizer per year, 300g of urea, 375g of phosphate fertilizer and 1035g of potassium fertilizer per 4-year-old tree, and 650g of urea, 835g of phosphate fertilizer and 2070 g of potash fertilizer per 8-year-old tree. At the same time, a certain amount of organic fertilizer should be buried every year to ensure an adequate source of fertilizer. Kiwifruit avoid chloride, when the concentration of chloride ion in the soil reaches 700 mg / kg, it will be toxic to the plant, so we should try to avoid the application of fertilizer containing chlorine (such as potassium chloride). (3) fertilization methods: ring ditch application, radial furrow application, strip application and sprinkling are commonly used.
