Many people find that their apple trees do not grow well in their own homes when planting them. Apple trees need to be fertilized multiple times a year, and the fertilizer used each time is also different. Below, I will provide you with a specific introduction to apple tree fertilization technology.
1、 Fertilization of apple trees with pre flowering and post flowering fertilizers
Apple trees need to be fertilized once a year in early April and mid May, which is known as pre flowering fertilizer and post flowering fertilizer. During these two fertilizations, nitrogen and potassium fertilizers should be the main fertilizers.
Under normal circumstances, each apple tree should be treated with one kilogram of urea and five hundred grams of potassium sulfate. After fertilization, record and water thoroughly.
2、 Apple Tree Base Fertilizer Fertilization
In the autumn of each year, it is necessary to timely apply sufficient base fertilizer to the apple tree. The base fertilizer should be phosphorus fertilizer and farmhouse fertilizer. In order to improve the absorption of fertilizer by the apple tree, the phosphorus fertilizer and farmhouse fertilizer can be stacked and fermented together before fertilization, and then directly applied to the apple tree after they mature.
3、 Spraying fertilizer on apple leaves
In addition to applying fertilizer to the roots of apple trees, foliar spraying is also important. It has been resolved that around 0.5% urea solution should be sprayed before July each year, and around 0.5% potassium dihydrogen should be sprayed after July.
In addition, during the growth period of the apple tree, if you want its flower buds to differentiate quickly, you can topdressing it in early June, using urea as the main fertilizer, which can quickly expand its young fruit and is suitable for high yield.
