Cherry tree planting: how to fertilize cherries in autumn?

How to fertilize cherries in autumn? Please introduce the methods of cherry fertilization. Cherry trees with less than 3 years old can refer to the following methods: young cherry trees under 3 years old are in the crown expansion stage, with exuberant vegetative growth, need more nitrogen, should be mainly nitrogen fertilizer, and should be supplemented with appropriate amount of phosphate fertilizer, in order to promote crown formation. For the young trees in the early fruiting stage of 3-5 years old, the number of flower buds increases with the change from vegetative growth to reproductive growth, so we should pay attention to controlling nitrogen, increasing phosphorus and supplying potassium; when the trees of more than 6 years old enter the full fruiting stage, we should increase the amount of fertilizer and supplement more potash fertilizer. 1. Cherry trees should apply base fertilizer in autumn. 1. The best time to apply base fertilizer in autumn is from September to October, and early application is better. 2. Selection of fertilization types: organic fertilizers such as high-quality rotten farm manure, pigs and cattle manure can be added with appropriate amount of compound fertilizer or phosphate fertilizer. 3. The method of fertilization for cherry trees: fill the bottom of the ditch with 20 cm thick crop straw and cover it with 20 cm soil, then mix the fertilizer and soil evenly and apply it into the ditch. The application layer of organic fertilizer is generally in the soil layer of 15-40 cm. 4, the amount of fertilizer applied in autumn is generally combined with hole expansion, farm manure or pig and cow manure: 50 grams per young tree, 100 kilograms per tree in full fruit; pure chicken manure: 10 grams per young tree, 30 kilograms per tree in full fruit; cake fertilizer: 15 grams per young tree, 30 kilograms per tree in full fruit. 2. Spraying foliar fertilizer during the defoliation period of cherry trees 1. The best spraying time: the cherry should be sprayed with foliar fertilizer one week before the defoliation in late autumn. Spraying time can not be too early or too late, early spraying urea will cause shoot germination or scorch leaves due to high urea concentration; too late spraying, nitrogen has not been absorbed by the leaves, but not transported to the tree. 2. The best spraying concentration: in order to increase the accumulation and concentration of nutrients in cherry trees, 0.5% urea should be sprayed on the leaves.
