What are the autumn apple tree management techniques?
top dressing. In the first ten days of September, a quick-acting phosphorus-potassium fertilizer was applied to the late-maturing varieties. At the same time, potassium dihydrogen phosphate was sprayed once every 10 days from now on, and it was sprayed three times in a row to promote the ripening of new shoots, promote fruit coloring and increase the content. After harvesting the fruits of the mid-late mature varieties, the urea solution is sprayed once every 10 days, and sprayed three times to prevent the leaves from falling off prematurely.
Early application of base fertilizer. From the end of September to the beginning of October, before the harvest of apples, the method of ring ditch or deep digging is applied to apply the farmer's fertilizer. When fertilizing, replace the position of fertilization in the previous year and combine it with irrigation.
Trim the branches. The currently extracted erect new shoots are softened and made horizontal, and the dense branches, erect branches, overlapping branches, and competition branches are removed to improve the light conditions; the two-year-old growth branches are worn at the junction of one or two years of life. The live hat is trimmed to promote the formation of flower buds in the two-year-old branches; in the middle of September, the prolonged branches of all the vegetative shoots are cut off to the younger part of the autumn shoots to reduce nutrient consumption.
Deep watering. Deeply turn when the new shoots of the fruit tree stop growing, and the depth should be 20 cm to 40 cm. Before the winter, the winter water is poured, and it is necessary to fill the water.
Scratch the old skin to prevent disease. After the tree enters the dormant period, the tree is scraped off, and the general manager of the tree can spray the wintering pests such as the small leaf moth larvae and the red spider mites, which are hidden in the skin, and can be disinfected and disinfected to reduce the growth of the ice soul. The scraped belt was burned out of the garden.
