Scope

Main Technical Content: Blueberries, also known as cranberries, belong to the Vaccinium genus of the Ericaceae family and are perennial deciduous or evergreen shrubs or small trees. Based on their tree characteristics, ecological features, and fruit characteristics, blueberries are divided into three categories: low-bush blueberries, rabbit-eye blueberries, and high-bush blueberries. There are four cultivar groups: southern high-bush blueberries, northern high-bush blueberries, semi-highbush blueberries, and dwarf blueberries. (1) Southern High-Bush Blueberries: This cultivar group is distributed in areas with a long growing season, warm winters, and high summer temperatures, with an average annual temperature of 18 to 20 degrees Celsius and a growing season of 256 to 285 days. The average January temperature is close to 10 degrees Celsius or above, with an absolute minimum temperature of -16 degrees Celsius or higher, making it suitable for cultivation in subtropical regions. The cold temperature requirement is less than 600 hours (temperatures below 7.2 degrees Celsius), but its cold resistance is poor, making it suitable for development in East China and South China. (2) Northern High-Bush Blueberries: This cultivar group is distributed in climatic conditions between the southern high-bush and dwarf blueberry groups. The average annual temperature is 10 to 12 degrees Celsius, with a growing season of 150 to 250 days. Winter monthly temperatures can reach below zero, and the absolute minimum temperature is below -20 degrees Celsius but not less than -3 degrees Celsius. (3) Semi-High-Bush Blueberries: This cultivar group has relatively short trees and strong cold resistance, making it suitable for cultivation in northern cold regions. The tree height of this group is 50 to 100 centimeters. (4) Dwarf Blueberries: This cultivar group is characterized by small trees, typically 30 to 50 centimeters in height. It has strong cold resistance and can be cultiva
