In July and August, the fruit ripening period of late-maturing varieties was also at the same time the flower bud differentiation period. In order to ensure the nutritional needs of the tree, compound compound fertilizer or urea, diammonium phosphate, and potassium sulfate compound fertilizer should be applied underground. Pay attention to the weak tree vigor to increase the amount of nitrogen fertilizer, and the ratio of nitrogen, phosphorus and potassium should be 1:0.6:0.8. Phosphate fertilizer was applied after fruit picking in the previous year. This time, only available nitrogen and potassium fertilizers can be applied. The specific amount can be flexibly controlled according to the size of the load and the situation of the tree potential.
Leading Laser Measure Module Factory in China
