Cherry trees have the characteristics of rapid tree growth. The growth of branches and leaves and flowering results are concentrated in the first half of the growing season. This period requires both growth and a large number of results. The trees consume more nutrients, and the flower buds differentiate more often after fruit harvesting. Completed in a short time, according to this cherry tree fertilization has the following characteristics:
1, pay attention to early fertilizer. It takes only 40 to 60 days for the cherry to ripen to fruit, and it requires nutrient concentration. Therefore, in addition to the autumn base fertilizer, the top dressing of the fruit should be performed before germination and at the early stage of fruit development. For the first time, quick-acting nitrogen fertilizer is the main ingredient. Apply NPK fertilizer or fruit tree fertilizer.
2, pay attention to fertilization after harvest. After fruit harvesting, in order to enhance the tree nutrient accumulation and promote flower bud differentiation, nitrogen, phosphorus, and potassium compound fertilizers may be topdressed.
3, Shizu base fertilizer. It is advisable to apply early in the fall, generally from 9 to 10 pounds per year in combination with ploughing. Each 667 m 2 of the plant is fermented with organic fertilizer (circle fertilizer, soil miscellaneous fertilizer, and human and livestock manure) from 2000 to 5000 kg.
4, top dressing outside the root. Spraying 0.3% urea, 0.1-0.2% borax, and 0.2-0.4% potassium dihydrogen phosphate mixture during blooming period have a good effect on the yield increase.
5, fertilization method. The cherry tree is not well developed in its vertical roots, and its roots are distributed shallowly in the soil, but its horizontal roots are well developed. During the growth period, fertilization, in order to reduce the root injury, can be focused on the application of radioactive rays.
