1. Fertilization management After the cherry fruit is picked, the flower buds enter a period of large differentiation. At this time, the new shoots are close to the stop growth period. Fertilizer (confinement fertilizer) should be applied immediately after harvesting. Reasonable fertilization can enable the tree to receive nutrients as soon as possible. Compared with autumn fertilization, there is more time for tree nutrient accumulation, which is conducive to the growth of flower buds. Fertilizer types: The types of fertilizers are quick-acting fertilizers that contain a variety of nutrients. Such as decomposed sheep manure, rabbit manure, decomposed bean cake water, compound fertilizer and other organic fertilizers and inorganic fertilizers containing multiple elements. When fertilizing, pay attention to the use of high-nitrogen and high-potassium compound fertilizers, which must be fully mixed with the soil to avoid root burning. Fertilization method: 1. Radial fertilization (strip); 2. Circular and semi-circular fertilization; 3. Furrow fertilization. Be sure to focus on fertilization. Young trees should be half a meter away from the trunk, and fruit trees should be one meter away from the trunk, and the vertical projection should be less than half a meter. 2. Pest management After protecting the leaves of the big cherry, it will soon enter the hot and humid season, which is prone to pests and diseases. Therefore, the cherry orchard after fruit picking should be sprayed with drugs in time to prevent diseases and insects and protect the leaves. 3. Pruning and thinning out dense branches in summer to solve the scenery conditions in the canopy Attention should be paid to grasp the favorable opportunity after fruit picking, and adjust the structure of the tree to improve the wind and light conditions in the crown. The erect strong branches that seriously affect the wind and light conditions in the crown should be thinned out from the base; the backbone branches and perennial branches on the periphery of the canopy should also be thinned out from the base. When thinning big branches, don't rush, and don't thin too many branches a year to prevent the tree from turning back. Generally, it is advisable to complete the treatment within 2-3 years.
