1. Seedlings The northern regions are generally planted in the spring. In the autumn, improper management of winter crops is prone to frost damage. Planting in spring usually takes place in March-April, and sprouts are planted before germination.
Generally used 2 to 3 years old seedlings, such a high survival rate of seedlings. Seedling height is generally more than 30cm, but varies by species. The indicators for judging the superiority and inferiority of seedlings are not only heights, but also depend on the degree of robustness of roots and branches. The roots of high-quality seedlings are well developed, and the roots of the seedlings are basically covered with lotus roots, and the shoots on the ground are thick and well developed, with basal branches appearing.
In addition, in addition to the main cultivars, but also to use more than 1 or 2 species of seedlings do pollination trees to increase production.
Seedling method When planting, remove the seedlings from the pods and observe the condition of the roots. If the root system is densely networked at the bottom, you need to use a knife to gently cut the bottom into a cross shape, remove the soil from the center part by hand, and remove the roots. Shun. If it is a bare root seedling, it needs to be rooted and then planted. When planting seedlings, it is necessary to dig a pit with a depth of 10 to 15 cm and a width of 20 to 30 cm in a planting bed or planting bed prepared in advance. Fill some small pits with wet acid peat soil or pre-prepared planting soil. Then, plant the seedlings and spread the roots to allow the added peat soil to surround the roots and raise the seedlings upwards. Once, in order to fully integrate the root system with the planting soil, the final covering of the earth to level with the ground.
2. After the land surface is covered and planted, the surface of the planting hole is covered with a layer of straw, humus, bark, sawdust and other organic materials. Ground cover has the effect of regulating ground temperature, preventing evaporation of surface moisture, maintaining soil moisture, and promoting root growth. Cover thickness is about 10cm, not less than 5cm.
3. Soil Improvement (1) Soil Acidity (pH)
Blueberry prefers acidic soils. It is the type that requires the lowest soil pH in all fruit trees. Among them, North Highland Blueberry requires a pH of about 4.3 to 4.8 in the soil, and rabbit eyes blueberries require a pH of about 4.3 to 5.3 to grow best. . If the soil pH is too high, the application of sulfur powder and acid peat can be reduced to a more suitable range. Most regions in China where blueberries can be cultivated have high soil pH and require soil improvement.

A boilersuit is a one-piece garment with full-length sleeves and legs like a jumpsuit, but usually less tight-fitting. Its main feature is that it has no gap between jacket and trousers or between lapels, and no loose jacket tails. It often has a long thin pocket down the outside of the right thigh to hold long tools. It usually has a front fastening extending the whole length of the front of the body up to the throat, with no lapels. It may be fastened with buttons, a zip, velcro, or snap fasteners. Boilersuits with an attached hood are available.
