1. At present, the main cultivated varieties in Chongqing are South Sorghum and Rabbit Eye, and the optional varieties are O 'Neill, Legacy, Tianhou, Emerald, Jewelry, Fog, Brilliant, Baldvin, Yu Anlan and V5. When building a garden, we should choose blueberry varieties according to local conditions, such as consumption patterns and soil conditions. At the same time, multi-varieties and different maturity are planted together, which prolongs the fruit picking period and reduces the planting risk of centralized listing or disastrous weather at flowering stage.

2. Blueberry, also known as Vaccinium uliginosum, is a perennial berry fruit tree of Vaccinium in Ericaceae. Blueberries are native to North America and have purple or blue fruits. A few varieties are red, nearly round, spherical or pear-shaped The diameter of a single fruit is 0.8 ~1.5cm, and the weight is 0.5 ~ 3.0g. Blueberry pulp is rich in anthocyanins, folic acid, ellagic acid, bacterial growth inhibitors, antioxidants, flavonoids and other compounds besides cellulose, fructose, vitamin A, vitamin C, and is known as "a functional healthy berry in 2 1 century".

3. The experimental research on blueberry introduction in China began in 1980s, and it was commercialized in 2000, and developed rapidly in 2006. By the end of 2020, the national blueberry planting area was 66,400 hm2. Chongqing is a suitable area for blueberry cultivation. According to incomplete statistics, by the end of 20021,the planting area of blueberries in Chongqing was about 1350hm2, and the total output was about 1050t. In this paper, the research results of high-yield and high-efficiency cultivation techniques and blueberry bee pollination experiments at home and abroad were summarized, and the high-efficiency cultivation techniques of blueberry in Chongqing including blueberry orchard establishment, tree pruning, fertilizer and water management, pest control and bird damage control were formed, which provided reference for blueberry planting in Chongqing.
