Regulating tree vigor and promoting development In August, the new shoots of apple trees entered the second prosperous period, and the fruit development entered the swelling period. Good tree vigor control played a key role in promoting the good development of young fruits. According to the tree age, tree vigor, results, etc., appropriate measures should be taken to regulate and control the tree vigor and healthy growth. To do a good job in summer pruning, the focus is to remove the upright and long branches, and useless branches that affect the light, so as to control the growth, improve the light conditions, and promote the development of fruit and the formation of flower buds. Another important aspect of fertilization, drainage and weeding to regulate tree vigor is to do a good job of fertilization. Topdressing is the first process to promote the formation of flower buds and fruit development. The amount of topdressing depends on the tree vigor. Phosphorus and potassium fertilizers can be applied once, and the focus is on potassium fertilizer. For example, early-maturing varieties can be fertilized in early July. Fuji apples are fattened once from mid-July to mid-August. Fertilizers such as phosphorus, potassium, calcium, and iron fertilizers play an important role in increasing the sugar content of fruits, promoting coloring, reducing physiological diseases of fruits, improving the photosynthetic performance of leaves and the quality of flower buds. Therefore, foliar spraying can promote Flower bud growth and fruit development are another key step. The commonly used fertilizers for foliar spraying are superphosphate, potassium dihydrogen phosphate, potassium sulfate, calcium chloride, calcium nitrate, plant ash and ferrous sulfate. In the actual management process, potassium dihydrogen phosphate and calcium chloride are mostly used. It is mainly used in combination. When spraying, the total salt concentration should be strictly controlled, generally not more than 0.5%. At the same time, we must also pay attention to the drainage and weeding of the orchard. In the rainy season, water should not accumulate in the orchard for a long time, otherwise it will affect the permeability of the orchard soil and the root growth of apple trees. Drain water in time after rainfall, keep the soil moisture in the orchard relatively stable, and hoe and plan after watering or rain to remove weeds in the garden.
