There are three major categories of blueberry cultivation, namely high blueberry, blueberry blueberry and rabbit blueberry. Among them, the high-growth blueberry is divided into three categories: North high blueberry, South high blueberry and half high blueberry. Short bush blueberries and half high bush blueberries are suitable for planting in temperate cold regions. North high bush blueberries and some half high bush blueberries are suitable for planting in warm temperate regions. Rabbit eyes blueberry and Nangao blueberry are suitable for planting in subtropical regions.
Dwarf plexus blueberries are short and 30 to 50cm tall. Cold-resistant, can be cultivated in low temperature regions of -40°C. The technical requirements for cultivation and management are simple, and it is extremely suitable for large-scale commercial cultivation of alpine mountains in the northeast.
Half-high bush blueberries are obtained by crossing high bush blueberries and low bush blueberries. The fruit is large, the quality is good, the tree is relatively short, and the cold resistance is strong. Generally it can resist the low temperature of -35°C and adapt to the cultivation in the cold regions of the north. The tree height is 50-100cm.
The high-growth blueberries include the southern high-growth blueberry and the northern high-growth blueberry. The southern high-growth blueberry is moist and warm. It is suitable for the development of the south of the Yellow River, such as Central and South China, and the northern high-growth blueberry likes the cool climate. , Cold resistance is strong, some varieties can resist -30 °C low temperature, suitable for the development of humid areas and cold regions in the north of China. The fruit of this variety is large, with good quality and good taste. Can be used for fresh fruit market sales variety cultivation, can also be processed or garden cultivation.
Rabbit eyes blueberry tree tall, long life, resistance to hot and humid, strict requirements on soil conditions, and drought. However, poor cold resistance, -27 °C low temperature can make many varieties frozen. It is suitable for cultivation in the hilly areas of the south of the Yangtze River basin and southern China. When developing to the south, it is necessary to consider whether the cultivated area can meet the cold-warm demand of 450-850 hours<7.2°C; when developing northward, it is necessary to consider frost-warming and winter-freezing damage.
Blueberries are classified into southern types: rabbit eye blueberry varieties and southern highgrow blueberry varieties; northern types: dwarf plexus blueberry cultivars, semi-high plexus blueberry cultivars, and northern high plexus blueberry cultivars. The characteristics of the southern type are mainly: the winter needs less cold, generally less than 600 hours (accumulated temperature below 7.2 °C), the minimum temperature in winter is about -15 °C; the characteristics of the northern type are mainly: the winter needs more cold, It is generally 800-1000 hours, and it can withstand temperatures below -30°C in winter.
The selection of blueberry cultivars is very important. Nowadays, more cultivars are cultivated on rabbit eyes, southern high clumps and northern high clumps. Rabbit eyes are more likely to be distinguished from the southern high clumps and northern high clump cultivars. Rabbit eye cultivars have serrated edges, while two high clump cultivars do not.
2. Choose the right blueberry varieties There are many varieties in each blueberry variety group. After selecting a good variety, select the varieties that are suitable for planting in the local area. There are many varieties of blueberries on the domestic market, but there are not many correct and pure varieties. How to ensure that the purchased blueberry varieties are correct and pure, then you need to sign a contract with the seedling seller to ensure that the blueberry varieties you purchase are correct and pure. The garden blue of the rabbit eye is late-maturing, the fruit is relatively small, the fruit color is deep, the sugar content is high, and the fresh fruit is easily broken when sold; if it is mixed and harvested with other varieties of fruits, when the fresh fruit is sold, it firstly affects the appearance, and then is not tolerant. Storage.
3. Choose high quality blueberry seedlings after the first two points are done, we must choose high quality blueberry seedlings. High-quality seedlings mainly have the following characteristics: 1 The plant is of suitable age, preferably 2 or 3 years old. (The newly planted seedlings or young tissue culture seedlings need to be carefully managed; the loss is greater after poor management; the seedlings are too large to be transplanted. It will be very difficult to ease it later. If it is slow, it can easily become a 'little old tree'). 2 The roots are well developed and the pot seedlings are best checked. 3 On the ground part, it is best to have 1 to 3 root sticks. This kind of seedlings has strong growth potential and is easy to form an ideal plant shape (blueberries are shrubs, and some blueberries have become small trees).
