Drought prevention: After planting, the seedlings are prone to drought. In addition to the rooting water that is poured when the plants are planted, they should be watered once every 7-10 days to keep the soil moist but no water is accumulated. Thinly cover the surface to reduce moisture evaporation. Within 2-3 years after planting, straw can be used to prevent stem drying. After the saplings gradually adapt to the environment and grow new roots, they can be removed.
Management during the growth period: The cherry tree is fertilized twice a year. Acid fertilizers are preferred. Once it is winter fertilizer, organic fertilizer such as bean cake, chicken manure and composting fertilizer are applied in the early spring. Another time, after falling, ammonium sulfate, ferrous sulfate, superphosphate and other fast-acting fertilizers are used. Normal big cherry tree fertilization, can use acupuncture, that is, at the edge of the canopy projection line excavation of a 10 cm deep ring groove fertilizer will be applied, this method is simple and conducive to the absorption of the root system. Afterwards, as the trees grow, the diameter and depth of the ditch will increase. The root distribution of cherry blossoms is shallow, and it requires good drainage and air permeability. Therefore, in the area around the cherry trees, especially in the distribution range of the roots, rolling of the vehicle should be avoided, and humans and animals should step on compaction soil. Otherwise, it will weaken the tree, shorten its lifespan, and even kill the roots.
