Relatively cold-tolerant, it can grow at MINUS 30 degrees, so it mainly grows in cold regions. Blueberries like loose and breathable deep soil. In addition, blueberries need plenty of sunshine during their growth.
1, temperature: generally, blueberries need a low temperature of less than 7.2 degrees for 800- 1200 hours to blossom and bear fruit normally. Only when the low temperature exceeds 800 hours, the semi-high bush blueberry will grow better. The low temperature of 800 hours is semi-high bush blueberry, and the minimum cooling requirement of short bush blueberry is 1000 hours.
2. Illumination: Blueberries are good for growth in long sunshine, while flower bud differentiation needs to be carried out in short sunshine. The semi-high-dwarf blueberry promoted the vegetative growth by supplying light for more than 12 hours, and the vegetative growth increased from 8 hours to 16 hours, reaching the peak at 16 hours.
3. Soil: Blueberries have strict requirements on soil, and the most suitable soil is loose, breathable and moist strongly acidic sandy loam or peat soil with high organic matter content.
Blueberry habitat
The quality of blueberries in North America is world-famous. Semi-high cluster blueberries are suitable for planting in temperate cold regions, northern high cluster blueberries and some semi-high cluster blueberries are suitable for planting in warm temperate regions, and rabbit-eye blueberries and southern high cluster blueberries are suitable for planting in subtropical regions.
China is mainly in Liaoning, Heilongjiang, Jilin and other regions. Many wild species resources of blueberry plants, such as Vaccinium uliginosum, Vaccinium uliginosum and so on, naturally grow in Changbai Mountain and Daxinganling Mountains in the northeast.
