The cherry tree grows rapidly and is clearly and centrally developed. The growth of branches and leaves and flowering and fruit setting are concentrated in the first half of the growing season. The flower bud differentiation is mostly completed within a short time after fruit picking. Chinese cherries range from flowering to harvesting for approximately 50 days and sweet (large) cherries for approximately 60 days. To this end, early fertilization should be based on the characteristics of the cherries, grasping the basal fat, flower fertilization and fruit fat. In general, the amount of nitrogen fertilizer should be less, the proportion of phosphorus and potassium fertilizer should be large, and organic fertilizer should be more.
Early application of base fertilizer in autumn, no later than in November, ring fertilizer, human and animal urine, soil miscellaneous fertilizer can be applied. In general, young trees and early fruit trees are fed with 30-60 kg of human excrement or 100 kg of circulated manure, and mature trees are used to produce 60-80 kg of livestock excrement or 200 kg of manure.
Fertilizing time before flowering or the first time of fruit speed, mainly available nitrogen fertilizer, can increase the fruit setting rate, promote shoot growth and leaf hypertrophy, lay a good foundation for flower bud differentiation. If spraying 0.5% urea 1 or 2 times in the early stage of flowering, adding 0.5% boron or 600 times potassium dihydrogen phosphate can increase the fruit setting rate.
Supplementing the fertilizer after picking up the fertilizer can increase nutrient storage in the tree and promote flower bud differentiation. After fruit picking, the fruit trees are transferred from the stage of flowering, the stage of nutrient depletion of leaves, to the stage of nutrient accumulation and begin to enter the qualitative stage of flower bud differentiation. Therefore, the main types of supplement fertilizers are quick-acting fertilizers such as decomposed human excreta, bean cakes and chemical fertilizers. The amount of fertilizer can be determined according to the age of the tree and the size of the canopy and how much the result will be. The general strain will be used to treat 60 to 80 kg of human excrement, 2.5 to 3 kg of cooked bean cake, 1.5 kg of ammonium sulfate, or 0.5 to 5 kg of urea. 1 kg. Can also be sprayed.
