Apple Potassium Fertilizer High Quality at the Late Stage of Apple Growth

Potassium is one of the important elements needed for apple trees, especially for improving apple quality and improving apple quality. The timely and appropriate application of potash fertilizer can not only increase the number of apple fruit, increase the sugar content, and increase the degree of coloration, but also can make the fruit color brighter, the skin clean and smooth, the intrinsic quality of flavor and taste can also be improved, and the disease resistance ability can also be correspondingly improve. The timely application of potassium to apple trees has little effect on the absorption of potassium in the early stage of growth, and then gradually increases. The critical period of absorption peak is in the middle and late stages of apple growth, generally in July-August. Applying proper amount of potassium fertilizer to fruit trees during this time will have a multiplier effect. If an equal amount of potash is applied before the early spring or flowering period, it will have no obvious effect on the yield increase or the increase in the degree of coloring. Appropriate amount of potassium can be applied to 1 kg of pure potassium per 100 kilograms of apples. If applied excessively, the physiological function of the fruit tree will be destroyed, affecting the absorption and utilization of other elements by the apple tree. In addition, when potassium fertilizer is applied to apple trees, potassium sulfate with high absorption and utilization efficiency should be selected. It is also possible to use organic fertilizer with high potassium content, such as vegetation ash or decomposed chicken manure, to spread under the trees, and then put it in shallow water after application. With 0.3% ~ 0.5% potassium dihydrogen phosphate solution or amino acid potassium 300 ~ 500 times foliar spray supplement, you can also receive better results.
