The first top dressing should be before the flowering. The fruit tree buds and flowers need to consume a lot of nutrients. If the nutrient supply is not available, the flowering period will be prolonged and the fruit setting rate will be reduced. Therefore, it is necessary to apply the quick-acting fertilizer in an appropriate amount.
The second time is the post-flowering fertilizer. This top dressing should be carried out immediately after the falling flower to reduce the physiological drop, promote the growth of new shoots and enlarge the leaf area. The first and second topdressing should be closely combined with the application of quick-acting nitrogen fertilizer. The mature manure of each plant is 100 kg of manure or 1 kg of urea.
The third time is the fruit swelling and flower bud differentiation during the topdressing. At this time, the fruit is rapidly expanding, the flower buds begin to differentiate, and the reproductive growth and nutrient growth are sharply contradictory. Applying proper amount of nitrogen, phosphorus and potassium fertilizers in time can improve the photosynthesis effect of the leaves and promote Nutrient accumulation, to meet the nutritional needs of fruit expansion and flower bud differentiation.
The fourth time is to stop the growth of the autumn shoots. The main role is to improve the photosynthetic function of the leaves, increase the accumulation of nutrients in the late stage of the tree, and promote the continued differentiation and fullness of the flower buds. For the third and fourth top dressings, the adult trees were given 50 kg of excrement, 1 kg of superphosphate and 0.5 kg of potassium sulfate. The fourth fertilization time: early maturing and medium maturity varieties can be carried out after harvesting, and late maturing varieties are carried out before harvesting.

The numbers on the Tape Measure are divided into two rows. One row of numbers is in centimeters/CM, and the other row is in inches. 1CM is about 0.3937 inches, and 1 inch is about 2.54CM. Therefore, the short distance between the two numbers is in centimeters. The longer one is inches, and the number fonts in centimeters are also smaller than those in inches, 100 cm = 1 meter. In use, the unit is generally in centimeters.
