1. Soil and Fertilizer Management Cherry fruit has a short development period and requires nutrient concentration. Pay attention to pre-flowering, fruit development, and post-harvest, post-harvest top dressing. The first time nitrogen fertilizer is combined with phosphorus and potassium fertilizer, and the second is phosphorus and potassium fertilizer. Mainly, after the fruit is harvested, the compound fertilizer is the main ingredient. It can also be used to treat human fecal urine, decomposed bean cake water, etc. (fertilizer is good for autumn). This fertilization is conducive to flower bud differentiation and increase the output in the coming year. After fertilization, water should be applied. After the flowers are cut off until the fruit matures, if the weather is dry, pay attention to irrigation to ensure adequate water supply. Pay special attention to drainage during the rainy season.

2. Summer pruning Cherry summer pruning main technical measures are topping, twisting tip, take branches, thinning branches, etc., the use of summer pruning to weaken the growing trend of branches, and promote the formation of short branches, with early results. 1 The thinning is mainly carried out after the fruit is picked, so as to eliminate the large branches and dense twigs that affect the ventilation and light transmission, and have no reservation value, and improve the ventilation and light transmission conditions. 2 Topping should start from mid-May, and leave 5 to 7 leaves topping for each 20 to 25 centimeters of length on the back branches, and 40 to 40 centimeters for every 50 to 60 centimeters of the main branch extending head and lateral branches. The long branches are opened at an angle of lychee and each head is 80-90 cm long and 60-70 cm long.
3. Diseases and Insect Pests Prevention Major cherry diseases include dry rot, gummy, root cancer, early defoliation, and root rot, and phytosanitary agents such as thiophanate-methyl, mancozeb, etc. Into the rainy season, Bordeaux's liquid control effect is good; root diseases should be promptly scraped off the lesions, tumors, and smeared with 10 to 20 times the sterilization superiority for disinfection. The main pests of cherries are caterpillars, moths, leafhoppers, and pear nets. They can be sprayed to prevent and treat insecticides such as juvenile urea, imidacloprid, and roll yiqing.
