1、 Basic introduction

Blueberry mainly grows in Europe, Russia, North America and other places. At present, there are about 90 kinds of blueberry in China. Studies have confirmed that the anthocyanin contained in it has a relatively good antioxidant effect. Human long-term use can play a certain protective effect on the eyes, improve the night vision ability, improve the ability of the eyes to adapt to the changes of strong and weak light, and also play a certain role in the protection of vision. In addition, it can strengthen capillaries, improve blood circulation, weaken the viscosity of platelets, prevent the production of blood clots and enhance heart and brain function

2、 Breeding method

1. Selection of planting land: the planting land needs to have sufficient water, with an annual rainfall of more than 800 mm and a leeward and sunny place. It is better to plant on flat land or gentle slope with loose soil, rich organic matter, excellent drainage and irrigation conditions and sufficient sunshine. It should be noted that it is best not to be sheltered by trees near the planting area in case there is not enough light. If you choose slope planting, do not plant it in the place where the cold air at the bottom of the slope stagnates, so as to avoid freezing injury

2. Soil: suitable for living in acidic soil and rich in organic humus. Bilberry is planted on the soil with high fertility, loose and deep soil and rich organic humus, which is of great help to improve the yield. Special attention should be paid to the timely removal of the roots of previous crops in the soil after selecting the land to reduce bacteria

3. Planting time: generally, the best planting time is around the beginning of spring every year. If sufficient water can be ensured in winter, planting can also be carried out in autumn and winter. At this time, it is necessary to improve the fertility of the soil. An appropriate amount of bark, sawdust and other substances can be added to the soil to improve its fertility. And pay attention to improving the acidity of the soil. If it is insufficient, it is necessary to add a small amount of sulfur acid into the soil

4. Fertilization: blueberry does not need much fertilizer. Excessive fertilization is harmful and unhelpful. It can be moderate. Excessive fertilizer will not promote its growth, but may also cause adverse effects. In the first year of planting, fertilization should be reduced as much as possible, or even not when the base fertilizer is sufficient. It should be noted that no matter when you apply fertilizer, you can't apply fertilizer directly to the root of bilberry to prevent burning

3、 Maintenance skills

1. Shaping and pruning: shaping and pruning is a necessary step to make blueberry grow well. After two years of growth, all the flower buds should be removed. From the third year, flowers and fruits can be reserved appropriately, but pay attention to the number of fruits, which can not be too much, otherwise the tree can not bear it, resulting in fruit loss. In addition, useless branches such as long branches, dead branches and old branches should be cut off in time to avoid consuming too much nutrition

2. Insect pests: in autumn and winter, all the cut branches and early fallen sick and disabled branches and leaves shall be cleaned out of the plantation and burned in a centralized manner, so as to reduce overwintering bacteria and insect sources. Combined with deep turning in winter, turn the soil 20 cm deep to eliminate overwintering pests in the soil

3. Bird damage: pay attention to prevent bird damage. At the fruit ripening stage, birds are driven away by bird proof nets or scarecrows, electric bird repellents, firecrackers and other means
