Blueberry, native to the three northeastern provinces and Changbai Mountain, is rich in nutrients, has a strong food value, and has a very high economic value! Blueberry originated in the three northeastern provinces, but it has been greatly developed in the Yunnan-Guizhou region, because the climate in the Yunnan-Guizhou region is more suitable for the growth of blueberries than the north. For blueberries, there are more than three years of seedlings here. I can’t talk about proficiency. I can only talk about the points learned from the older generation of blueberry technicians.
First, the transplanting time of blueberries
Blueberries can be grown all year round, but the best time, like most seedlings, has the highest survival rate after the fall to the spring! That is almost the time now. Now planting, a small number of results in the second year.
Second, the soil
The most critical, the soil! Blueberries grow in acidic soils with a pH between 4.5 and 5.5, but the average soil pH is about 6 or so. Therefore, pine needles, moss moss, sulfur powder, etc. need to be added to the soil. Most blueberry growers nowadays Acidic soil made from pine needles, or a layer of humus covered directly under the fallen pine trees, because pine leaves are acidic.
Third, the need for cooling
Potted blueberries, in order to get results, must have a certain amount of cold demand, that is, in the winter, to ensure that blueberries sleep at a low temperature below 7 degrees Celsius. The lowest temperature varieties that blueberries can tolerate are different. As long as the cooling capacity is enough, they can be moved indoors.
Fourth, water and fertilizer management
Blueberries are afraid of drought, but they can't be watered too much. Because the roots are shallow, so keep the soil moist, pay attention to drainage and prevent rotten roots. Reduce watering during fruit development and rapid maturity to prevent blueberry long leaves from growing. The fertilizer is generally phosphorus pentoxide and ammonium sulfate, and it is not possible to apply a nitrate fertilizer, such as ammonium nitrate.
