Embodiment Construction

[0008] On the basis of the conventional cultivation and management of hawthorn, use biological bacteria organic fertilizer mixed with trace elements and potassium sulfate compound fertilizer as the base fertilizer in autumn; apply potassium sulfate compound fertilizer once a year after fruit setting; in spring and summer, manure, dead grass, fallen leaves, Straw and other materials are laid flat in the tree tray; before germination and after fruit picking, the medicine is irrigated once, and the systemic fungicide Fuxing mixed rooting agent is selected. The amount of irrigation liquid is the centimeter of the circumference of the trunk multiplied by 2.6. Protect leaves and prevent diseases 3-5 times; carry out slightly heavy pruning in late winter.
