Peach tree management measures after the beginning of spring

Fertilization peach branches grow rapidly and the fruit development period is short, so fertilization should be timely and reasonable. Fertilization in spring should not exceed late February, and it is better to apply early. The fertilizer types are ammonium bicarbonate, phosphate fertilizer, potash fertilizer and organic fertilizer. For a peach tree that produces 35-50 kilograms of fruits, 40 kilograms of decomposed human and livestock manure, 0.25 kilograms of urea, 0.15 kilograms of superphosphate, and 0.4 kilograms of potassium chloride per plant are applied. Fertilization method: Dig 2 to 3 fertilization pits under the tree canopy and close to the root distribution area, mix the organic fertilizer and nitrogen, phosphorus, and potassium fertilizers thoroughly before applying, and cover the soil in time after application. In case of drought and rain before germination, light manure water should be irrigated to resist drought and drainage to prevent stains.

Disease and insect control Before the flower buds germinate in March, the disease and insect control cannot be relaxed. During this period, there are mainly gum disease, leaf disease, scale insects, and peach perforation disease. Spray stone-sulfur mixture before germination, and spray two or three times of fluoperic acid (or 1500 times Jingguojing) + Beitianda silicone mixture (one week interval) after the flowers are decayed, which can effectively control perforation. The occurrence of disease; spraying Albit plant growth estrogen can play a role in accelerating germination and preventing freezing damage from cold spring.
