The orchid is more drought-resistant and resistant to damp and heat, but its cold resistance is poor. The low temperature below-15 ℃ is susceptible to freezing injury, so it is suitable for cultivation in warm areas. When it needs to develop to the north, it is necessary to consider the freezing injury in winter and non-seasonal temperature change, while in the south, it is necessary to consider whether the cultivation land meets the requirement of low temperature during the dormancy period of varieties, and the low temperature of less than 7.2 ℃ is generally required to be between 300 and 800 hours.

Its characteristic is that it requires less low temperature and is more suitable for planting in warm areas than high-clump blueberries in the north. It is better to be planted with O'Neill, with a spacing of 1.2 to 1.5 meters.

The sharp blue tree is 1 to 2.5 meters high, and the one who is as high as 3 meters. The tree is strong and takes shape quickly. The fruit is dark blue, the pedicel is very small, the fruit is medium size, and the storage and transportation resistance is poor. The cooling capacity is 150 to 300 hours. The pH value of soil suitable for growth is 4.3-5.5. Like humid and warm climate conditions, it is suitable for planting in Jiangsu, Zhejiang, Anhui and Jiangxi in southern China.

The fruit ripening period is more concentrated. The late-ripening fruit is small and thick-skinned. The pulp is compact, the storability is good, suitable for mechanical harvesting, suitable for fresh fruit sales. The elongation of branches is limited to relatively small areas, so re-cutting or cutting cuttings is disadvantageous to growth. It has strong adaptability to soil and is suitable to be planted in most areas of the Yangtze River basin in China, and the planting effect of pinnacle and garden blue is better.
