Second, water and fertilizer management The water content of big cherry plants is about 70%, so it is particularly sensitive to water demand. Under normal circumstances, when there are many branches and leaves and the temperature is high, it is necessary to water them frequently, otherwise the garden soil will be too dry, which will affect its growth, flowering and fruiting. It is necessary to master the principle of thin fertilizer and diligent application. It is suggested to spray a new type of high-fat film to improve the utilization rate of fertilizer efficiency.
Third, pruning and shaping In order to improve the economic value of big cherries, the plants should be appropriately pruned. When the plants survive, they should be cut off from the base 20 cm upwards, so that the trunk will sprout one after another, produce more new branches and bear more fruits. For fruiting plants, applying mother liquor of roasted flowers before flowering and spraying Zhuangguodiling solution in bud stage and fruit expansion stage can thicken fruit stems and improve nutrient transport. Prevent falling flowers, falling fruit, cracking fruit, hard fruit and deformed fruit, and make the fruit beautiful in color, shape and taste. At the same time, the medium and long branches should be appropriately cut short. It is suggested to stick an antibacterial film on the trimming mouth to promote wound healing.
Fourth, the big cherry with heat preservation and moisture preservation is cold-resistant, and it can be coated with protective trees in the north to prevent cold and winter.
