How to fertilize fruit trees in June?

How to fertilize fruit trees in June? Please give guidance on the method of topdressing in the first and middle of June with phosphorus as the main fertilizer, expanding young fruits and enriching flower buds; from July to August, topdressing is dominated by potassium, with obvious yield increase and bright fruit color. It is the best time to topdressing fruit trees in the critical period of nutrients and the period of fruit expansion. This year, the fruit is large and the yield is high. Next year, the flower buds are full and there are many fruits. The best time for topdressing in the critical period of nutrients: the critical period of nutrients from the first ten days of June to the end of June, that is, the critical period of topdressing after the spring shoot stops growing, during this period, flower buds begin to differentiate, young fruits expand rapidly, and scientific and reasonable topdressing is directly related to the number of flower bud differentiation and flower bud quality, which determines the yield of next year. What is needed most in this period is phosphorus, which can enrich branches, improve leaf function and increase the output of leaves to produce nutrients. The best time for topdressing in the fruit expansion period is from mid-late July to early August, that is, the highest nutrient efficiency period, during which the fruit trees have the strongest nutrient absorption capacity, the fastest absorption rate, the highest fertilizer use efficiency and the most obvious yield-increasing effect. According to the growth and development characteristics of fruit trees, this period should be based on phosphorus and potassium fertilizer, especially the supplement of potassium elements.
