Winter Fruit Management Technology

1, on the frozen before pouring enough water, frozen water, fertilization. This fertilizer is extremely beneficial for flowering and fruiting in the second year. 100 kg of organic fertilizer can be applied to each plant, and 0.5 kg of organic fertilizer is applied per 0.5 kg of fruit, depending on the size of the tree, and 1 to 2 kg of urea per plant.
2. Do a good job of whitening the trunk to prevent freezing damage. Trunk with 10% lime water, mixed with appropriate amount of loess, salt, vegetable oil, applied to the branches of fruit trees in the early autumn and early winter, can ease the temperature changes on the surface of branches, to prevent frost damage and rot.
3. 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.
4, do a good job in the spring old warp scraping. From the end of February to the beginning of April, the germs and pests hidden under the old skin can be eliminated, and the number of overwintering can be reduced. However, the skin scraping should not be excessive, and the old skin scraping must be burned.
5, do a good job of apple rot disease curettage. From October to November and from February to March in the following year, it was the peak of two apple rots. It was necessary to inspect and scratch the diseased skin regularly to protect the new rot.
6, do a good job in the early spring tree disinfection. In early March, the whole tree sprayed 1 to 2 times of 50 to 100 times of Formamide arsenic to eliminate bacteria. In early April, it sprayed 3 to 5 Baume degrees of lime sulfur to kill overwintering spider mites, aphids and pathogens. In the bud stage, spray 0.5 times of Baume degree lime sulfur.
7, pouring enough germination water, Shizu 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.
8, branches of fat. During the germination period of spring fruit trees, branches sprayed 1-2 times of 0.5% urea and 0.3% borax, which resulted in uniform flowering period, flower hypertrophy, increased fruit set rate, and neat fruits. Can also be sprayed twice in this period 200 ~ 300 times Hui Man Fung, so that budding in advance, improve the fruit set rate.
