What are the blueberry brands? How to grow blueberries?

I believe everyone is familiar with blueberries, but how much do you know about blueberry cultivation? Here is some information for you.

Blueberry growth habits

There are three major types of cultivated blueberries, namely highbush blueberries, lowbush blueberries and rabbiteye blueberries. Among them, highbush blueberries are divided into three categories: northern highbush blueberries, southern highbush blueberries and semi-highbush blueberries. Lowbush blueberries and semi-highbush blueberries are suitable for planting in temperate cold regions, northern highbush blueberries and some semi-highbush blueberries are suitable for planting in warm temperate regions, and rabbiteye blueberries and southern highbush blueberries are suitable for planting in subtropical regions.

Lowbush Blueberry

The tree is short, 30 to 50 cm tall. It is cold-resistant and can be cultivated in low-temperature areas of -40℃. It has simple requirements for cultivation and management techniques and is very suitable for large-scale commercial cultivation in the high-altitude and cold mountainous areas of Northeast China. The yield per mu is about 500 kg. 1. Blomidon Canadian variety, medium-ripening. It matures in mid-July in the Changbai Mountain area. The fruit is round, light blue, covered with thick fruit powder, has a good flavor, and has a light and refreshing aroma. The tree grows strong and produces well. It has strong cold resistance. It is the first choice variety for the development of blueberries in high-altitude and cold mountainous areas. This variety has been confirmed as a designated variety for supplying processed frozen fruits to the Japanese market. Blueberry 2. Fundy Canadian variety, medium-ripening. The fruit size is slightly larger than that of Blomidon, light blue, and covered with fruit powder. It has high yield and early production.

Half-highbush blueberry

Obtained by hybridization of highbush blueberry and lowbush blueberry. The fruit is large, the quality is good, the tree is relatively short, the cold resistance is strong, it can generally withstand low temperatures of -35℃, and it is suitable for cultivation in cold northern regions. The tree height is 50-100cm. 1. Northland American variety, medium-early maturity. The tree grows robustly, moderately open, and the tree height can reach 1.2m. Cold-resistant, extremely high yield. The fruit is medium-large, round, medium-blue, medium-hard in texture, with small and dry fruit stem scars, relatively concentrated maturity period, and good flavor. 2. Northblue American variety, late maturity. The tree grows robustly, the tree height is about 1m, cold-resistant, and high-yield. The fruit is large, dark blue, hard in flesh, good flavor, and storable. 3. Northcountry American variety, medium-early maturity. The tree is medium-strong, the tree height is 70cm, cold-resistant, early, high-yield, and continuous high-yield. The fruit is medium-large, bright sky blue, sweet and sour, and has a good flavor.

Highbush Blueberry

There are two categories: southern highbush blueberries and northern highbush blueberries. Southern highbush blueberries prefer humid and warm climate conditions and are suitable for the areas south of the Yellow River in my country, such as central and southern China. Northern highbush blueberries prefer cool climates and have strong cold resistance. Some varieties can withstand temperatures as low as -30°C and are suitable for the humid coastal areas and cold regions in northern my country. This variety group has large fruits, good quality, and a good taste when eaten fresh. It can be cultivated as a variety for sale in the fresh fruit market, or it can be processed or cultivated for home use.

Varieties of blueberries

1. Coville: American variety, medium-ripening variety. Strong growth, high yield, large fruit, medium blue color, excellent quality for fresh eating and processing. One of the outstanding features of this variety is that the fruit matures for a long time. In Changchun, it takes 45 days from the first batch of fruit to the last batch of fruit. It is an excellent variety for the local fresh fruit market.

2. Darrow Blueberry is an American variety that matures late. The tree grows robustly and upright, and produces high yields continuously. The fruit is large, light blue, hard, with a medium pedicle scar and good flavor.

3. Bluecrop: American variety, medium maturity. The tree grows robustly, blooms, and is extremely drought resistant. It is extremely productive and has a strong ability to produce high yields continuously. The fruit is large, light blue, with thick fruit powder, hard flesh, dry fruit stem marks, light aroma, and good flavor. Rabbiteye blueberry trees are tall, long-lived, resistant to humidity and heat, not demanding on soil conditions, and drought resistant. However, they have poor cold resistance, and many varieties can be frozen at -27°C. It is suitable for cultivation in hilly areas south of the Yangtze River Basin and South my country. When developing to the south, it is necessary to consider whether the cultivation area can meet the cold temperature requirement of 450~850 hours <7.2°C; when developing to the north, it is necessary to consider frost damage during flowering and freezing damage in winter. The main excellent varieties are:

1. Baldwin is an American variety that matures late. The plant grows robustly and upright, with a large crown and strong continuous high-yield capacity. It requires 450 to 500 hours of cold temperature. It has strong disease resistance. The fruit ripens for 6 to 7 weeks. The fruit is large and dark blue, with a dry and small pedicle mark. The fruit is hard and has a good flavor.

2. Gardenblue: American variety, late-maturing. The plant grows robustly. The fruit is large, light blue, hard, with a dry pedicle. It has a good flavor when fully ripe.
