Pour enough frozen water and fertilize before freezing. This fertilizer is extremely beneficial for flowering and fruiting in the second year. 100 kg of organic fertilizer can be applied to each plant, 0.5 kg of organic fertilizer is applied per 0.5 kg of fruit, and 1 to 2 kg of urea per plant is used depending on the size of the tree. Do a good job of whitening the trunk to prevent freezing of the trunk. Use 10% lime water, mix appropriate amount of loess, salt, and vegetable oil, and apply it on the stems of fruit trees in the early winter and early autumn to ease the temperature changes on the stem surface and prevent frost damage and rot. Do a good job of winter trimming. Can be carried out after falling leaves, do not injure the bark, to protect the larger cut rot to be rot and to protect against rot. Do a good job of scraping the old skin in spring.

Pouring enough germination water to apply base fertilizer. After the soil is thawed, a fertilizer is applied, and urea is used as the main compound with some nitrogen, phosphorus, and potassium multi-element compound fertilizers, and the water is poured. Branches make up fat. During the germination period of spring fruit trees, branches sprayed once or twice with 0.5% urea and 0.3% borax, which resulted in uniform flowering period, flower hypertrophy, increased fruit setting rate, and neat fruits. Can also be sprayed twice in this period 200 to 300 times Huimanfeng, so that budding in advance, improve the fruit setting rate. China Agricultural Network Editor
