Planting techniques and management methods of blueberry planting conditions of blueberry

Blueberries are a little more expensive than ordinary fruits in the market. Even if some people have not eaten blueberries, they have often eaten other blueberry-flavored snacks. In fact, people eat the right amount of blueberries, not only can enhance immunity, but also can beauty, play a role in protecting eyes. Therefore, with the increasing market demand for blueberries, more and more people begin to grow blueberries.

Planting techniques and management methods of blueberry

1. Soil acidity (pH value) Blueberry likes acidic soil, which requires the lowest soil pH value among all fruit trees. Among them, the soil pH value of Beigaocong blueberry is about 4.3-4.8, and that of rabbit-eyed blueberry is 4.3-5.3. If the soil pH is too high, the application of sulfur powder and acid peat can be reduced to a more suitable range. In most of the areas where blueberries can be cultivated in China, the soil pH value is on the high side and soil improvement is needed.

2. The adjustment method of soil pH value if the soil pH is less than 5.5, it can be adjusted with the adjusted acid peat and other organic materials (every m3 of peat is evenly mixed with 1~1.5kg sulfur powder for more than 3 months, the pH value is about 3.5-4.0).

3. It can reduce the soil pH value by about 1.0. If the current soil pH value is between 5.5 and 7.0, it needs to be adjusted by applying sulfur powder and increase the soil organic matter at the same time. The adjustment of soil pH value with sulfur powder should be carried out 3-4 months before planting.

Planting conditions of blueberry

The main results are as follows: 1. The soil pH value of the garden site is 45.5, and the optimum soil pH value is 4.04.8. The content of soil organic matter is 8% to 12%, at least not less than 5%, the soil is loose, well ventilated, moist but without stagnant water. If the local rainfall is insufficient, an adequate source of water is needed. In order to solve the problem of stagnant water in summer, the strip platform field method can be used.

2. After selecting the garden plot, the green manure should be pressed and turned deeply one year before planting, and the suitable depth should be 20~25cm. If there are more weeds, you can spray herbicides one year in advance to kill weeds. The soil types that do not meet the requirements of blueberry should be improved before planting to facilitate the growth of blueberry.

3. The regulation of high soil pH value is an important factor limiting blueberry cultivation. Too high soil pH value often leads to iron deficiency and chlorosis, poor growth, low yield and even plant death. The effect of applying 130g sulfur powder can be maintained for more than 3 years, and other types of soil can refer to this amount.

How to raise blueberries

1. Tissue culture method was used to cultivate half-height blueberry and dwarf blueberry seedlings.

1. Start-up culture: using stem tip or stem segment, sterilizing 8min with 75% alcohol for 30s, then sterilizing 8min with 0.1% mercury, then rinsing it with sterile water for five times, then inoculating it into culture medium for 16 hours, light intensity 2000-3000 lux, temperature about 23 ℃.

2. Multiplication culture: wait for the seedlings to grow in full bottle, transfer repeatedly until the required quantity.

3. Examination: the bottle seedlings grow well, the color is normal, the infection rate is controlled within 5%, the quantity is moderate, and it is qualified.

2. Transplanting

1. After three days of seedling training, the bottle seedlings were cut into stem segments of about 3cm, soaked in 10min with 800x carbendazim and rooting powder, and transferred to a seedling plate filled with water moss. The temperature was controlled at 1528 ℃ and the humidity was 700.90%. Shade net was used to shade the stem until the stem took root. Spray 800 times carbendazim and rooting liquid every 15 days.

2. After rooting, it was moved into a nutrition bowl of 12 × 13 cm, and the ph value of seedling soil was controlled at about 4.5. at the same time, it was mixed with saw foam or pine needle.

3. Appropriate watering every day, observe the disease and insect situation, timely prevention, wait for the root system to grow full nutrition bowl can be moved into the field.

How to harvest blueberries

The ripening period of blueberry fruits is different between Rabbit Eye and Nangao Cong. Generally, the harvest lasts for 20 to 30 days, usually once a week. The fruits should be picked manually when they are fresh, and can be harvested by machinery for processing. The diseases of blueberry are caused by fungal diseases, bacterial diseases and nematodes. China is a new introduction and cultivation area, and the occurrence of diseases and insect pests is less.

In the above article, the editor also popularized some planting conditions and management techniques of blueberries for everyone. In fact, the commercial prospect of growing blueberries is relatively good. After all, blueberries, as a kind of fruit, are welcomed and loved by the majority of female friends.
