Generally, .5% urea can be sprayed 2-3 times after germination and before fruit coloring; Spraying .3% borax for 1-2 times during flowering period; .3% potassium dihydrogen phosphate can be sprayed 2-3 times during the fruit coloring period; Spraying .5% urea 1-2 times in time after fruit picking. Spraying time is usually carried out in the afternoon and evening every day.

fertilization period is divided into base fertilizer and topdressing. The period of basal fertilizer is from September to November, and it is better to apply it early. Topdressing is mainly two times, that is, topdressing before flowering and topdressing after harvest. Then according to the actual situation, spray fertilizer. Therefore, it is collectively referred to as "one base and two additional sprays".

Cherry trees have the characteristics of rapid growth, with branches and leaves growing, flowering and fruiting concentrated in the first half of the growing season. During this period, they need to grow and bear a lot of fruits, and the tree consumes a lot of nutrients, and flower bud differentiation is mostly completed in a short time after fruit picking. Therefore, fertilization of cherry trees has the following characteristics:

Before winter, base fertilizer should be applied in autumn from September to November, with high-quality ring fertilizer, soil miscellaneous fertilizer and rot.

Fertilizing cherry trees every year is to dig 4 to 5 centimeters away from the trees after thawing in the early spring. In order not to hurt the roots, apply some fermented farmyard manure or organic fertilizer, rapeseed cake, half a catty of urea and compound fertilizer, and apply fertilizer according to the size of the trees. After applying fertilizer, cover the upper layer with the original soil and water it in time, so that the cherry trees grow vigorously and bloom more.

All these nutrients must exist and be distributed in a balanced way during the flowering and fruiting period of cherry, so as to meet the needs of young fruit development. Meet the nutritional needs of young fruits. Without the interference of external environment, the growth and development will be basically consistent and the fruit size will be uniform.

organic fertilizer should be the main fertilizer for cherry. We know that the decomposed organic fertilizer is not only comprehensive and balanced in nutrition, but also long and mild in fertilizer effect, which can improve the resistance of cherry trees, and also improve the appearance and taste of cherries. Everyone who has planted the ground knows that fruits and melons taste sweetest when using organic fertilizer.
