When apples are fertilized in spring, for orchards that have not been fertilized in autumn and winter, they should be applied immediately after thawing. After fertilization, if the garden is irrigated, it should be watered once, and should be lightly hoeed to protect moisture. In dry land orchards, topping harrows should be used to protect moisture, and then fertilization should be used, and then the orchard should be quickly leveled and patted to protect moisture. Young and weak trees are sprayed with new high-fat film and covered with the film to increase the temperature and protect the moisture, and promote the healthy growth of the tree. ****** Cooperate with spraying photosynthetic nutrient film fertilizer to help absorb more light fertilizer and conventional fertilizer.
