The latest distribution of blueberries

Blueberry is a blue berry, a perennial shrub and small berry tree of the genus Ericaceae. Its origin is North America. Because the fruit is blue, it is called blueberry. The fruit is rich in nutrients, which can prevent brain nerve aging, protect vision, strengthen heart, fight cancer, soften blood vessels, enhance human immunity and other functions. Let's take a look at the distribution of blueberries.

Distribution of blueberry producing area

Blueberries are distributed all over the world, mainly in cool and sunny climates, such as Korea, Japan, Mongolia, Russia, Europe, North America and Chinese mainland in Heilongjiang, Inner Mongolia and Changbai Mountain in Jilin Province. growing at 900m to 2300 m above sea level, blueberries are found in coniferous forests, peat bogs, mountain tundra and pastures, and are also an important part of heather shrubs.

Blueberries are mainly produced in Liaoning, Heilongjiang, Jilin and other areas in China. There are many wild blueberry varieties such as Benedictine blueberry (commonly known as Benedictine, persimmon) and blueberry in Changbai Mountain and Daxing'an Mountains in Northeast China.

The producing environment of blueberry

There are three types of blueberries, namely, alpine blueberries, dwarf blueberries and rabbit eye blueberries, among which high bushes blueberries can be divided into three categories: North high bushes blueberries, south high bushes blueberries and semi-high bushes blueberries. Dwarf blueberries and semi-high bushes blueberries are suitable to be planted in temperate cold zones, north high bushes blueberries and some semi-high bushes blueberries are suitable to be planted in warm temperate zones, rabbit-eyed blueberries and southern high bushes blueberries are suitable to be planted in subtropical regions.

Blueberry cultivation in China started relatively late, mainly from the north, semi-high bushes, dwarf bushes, and rabbit-eyed blueberries, geographically scattered, with a planting area of about 20000 mu by the spring of 2009. it is mainly distributed in Shandong, Jilin, Liaoning, Jiangsu, Guizhou, Yunnan and so on, of which Shandong Province has the largest industrial planting area.

The development of blueberry

1. The course of development: the cultivation of blueberry in China started relatively late, mainly from the north, half-height clump, dwarf clump, and rabbit-eyed blueberry. Geographical dispersion, the planting area as of the spring of 2009 is about 20000 mu, mainly distributed in Liaoning, Heilongjiang, Jilin, Jiangsu and so on. Among them, Liaoning Province has the largest industrial planting area.

2. Oceania: blueberries were not successfully introduced in 1950, seeds were introduced and varieties were selected in 1970, seedlings were introduced and cultivated in the late 1970s, and by 1990, the area reached 1700 hectares, mainly concentrated in the eastern coastal areas. the main cultivated varieties of alpine blueberries are "Lanfeng", followed by "Spartan" and "Sharp Blue". On the basis of introduction, Australia has made great achievements in cross breeding and bred excellent varieties adapted to its own climate, which gradually replace the introduced varieties. In production, the geographical location of the southern hemisphere is used for production, fresh fruit is supplied in winter in the northern hemisphere, and the fresh fruit is exported to North America and Europe.
