1. Seedling planting: Generally, it is planted in spring and autumn in northern areas, and it is prone to freezing injury due to improper management in winter. When planting seedlings, fill some wet acidic peat soil or pre-prepared planting soil in the pit, then plant seedlings and lay roots, so that the added mixed peat soil surrounds the roots of seedlings, and finally cover the soil until it is flush with the ground.

2. Surface covering: after planting, take local materials and cover the surface of the planting hole with a layer of straw, humus, bark, sawdust, etc. Or spray a new layer of high-fat film, which can adjust the ground temperature, prevent surface water from evaporating, maintain soil moisture and promote root growth.

3. Fertilization: Blueberries are plants sensitive to fertilizers. Because of the high alkali concentration in soil, excessive fertilization will damage the root system and lead to plant death. Pollution-free cationic surfactant Wang Cuihua No.2 can be used to promote flowering genes and make fruit trees blossom and bear more fruits. Spray Zhuangguodiling in time to thicken the pedicel of fruit and increase nutrient transport in young fruit stage.

4. Overwintering protection: Although dwarf blueberries and semi-tall blueberries have strong cold resistance, freezing injury still occurs from time to time. The main manifestations are bolting and flower bud freezing injury in winter, and all the aboveground parts can be frozen to death in special years. Therefore, wintering protection is also an important measure to ensure the yield in blueberry cultivation in cold regions. For example, piling snow to prevent cold, coloring trees to protect them and so on.
