First of all, the name source

The name of blueberry comes from the literal translation of English "blueberry", which means blue berry. Vaccinium uliginosum (also known as persimmon and Vaccinium uliginosum) produced in northern China is often called blueberry.

Second, the cultivation history

The history of blueberry cultivation in the world is about 1 century, which first started in the United States. In 1906, Kerviel first started the selection of wild blueberries. In 1937, 15 varieties were selected for commercial cultivation.

By the 1980s, the United States had cultivated more than 100 fine varieties adapted to various climatic conditions, forming major economic producing areas in Maine, Georgia, Florida, New Jersey, Michigan, Minnesota and Oregon, with a total area of 1.9 million hectares. Blueberries have become the main fruit tree varieties in the United States.

After the United States, countries all over the world are scrambling to introduce and cultivate, and have carried out their own research and cultivation according to the climate characteristics and resource advantages. Holland, Canada, Germany, Austria, Denmark, Italy, Finland, Britain, Poland, Romania, Australia, Bulgaria, New Zealand and Japan have successively entered commercial cultivation.

According to statistics, by the end of 20 13, more than 30 countries and regions around the world had started industrialized cultivation of blueberries, with a total area of120,000 hectares and an output of over 300,000 tons.

Third, the morphological characteristics

1. Trunk

Shrubs are clustered, and the size and shape of trees are significantly different. The height of rabbit eye blueberry can reach 10 meter, and it is often controlled at about 3 meters in cultivation. The height of high-clumped blueberry trees is generally 1-3 meters; The height of the semi-high shrub blueberry tree is 20-100 cm; Shrub blueberry trees are 30-50 cm tall. The height of the rabbit eye blueberry tree can reach 10 m, the shorter red bean blueberry tree is 5-25 cm, and the shortest cranberry grows creeping, with the height of only 5- 15 cm.

Step 2 leave

Blueberries are evergreen deciduous plants. Leaf blade solitary, alternate, sparsely opposite or whorled, entire or serrate. High-bush, semi-high-bush and low-bush blueberries shed their leaves before winter, and the eyes of rabbits are evergreen, and the leaves can be preserved in trees for 2-3 years. The most common leaf shape is oval, without stipules.

The size of leaves varies with species. The leaf length of high cluster blueberry can reach 8 cm, short cluster blueberry is generally less than 1 cm, and the leaf length of rabbit eye blueberry is between high cluster blueberry and short cluster blueberry. Most blueberry varieties have fluff on the back of their leaves, and even some varieties have fluff on their flowers and fruits, while dwarf blueberries have almost no fluff on their leaves.
