There are several techniques for blueberry cultivation in black soil

Blueberry cultivation requires a suitable sandy loam soil with good drainage and loose drainage, and it is not easy to accumulate water if the soil is moist.

I think it's better to mix it. The moisture of the sand soil is lost too quickly, so it is better to mix some loess.

According to the planting experience in many places, the external conditions for blueberry growth demand are summarized:

First, blueberries like to grow in highly acidic soils. Rabbit eye blueberry requires the soil pH value to be between, and the maximum is not exceeded, otherwise it will affect its growth.

Second, the soil for planting blueberries requires an organic matter content of more than 5%, and the groundwater level is below the meter. The soil is clayey and high in calcium, which is not conducive to its growth.

Third, winter requires a certain amount of cold temperature, but not too cold. Generally, it is required that the freezing day in winter is about 20 days; Too hot or too cold for it to grow.

Fourth, it is a shallow-rooted plant, and newly planted seedlings are not drought tolerant. Productive planting requires good irrigation conditions.

How to grow blue plums:

1. First of all, buy blueberry seedlings, it is best to choose 2-3 year old seedlings.

2. Choose a blueberry orchard.

3. Familiar with the environment required for blueberry growth: blueberries can grow healthily in acidic media, and blueberries like humidity and sun.

Blueberry's requirements for soil: Blueberries like acidic and coarse positive soil, which is the lowest type of soil pH among all fruit trees, among them, the northern high-bush blueberry requires the soil pH value to be around the right, and the rabbit's eye blueberry requires the pH value to grow best around the left. If the soil pH is too high, the application of sulfur powder and acidic peat, can be reduced to a more appropriate range.

Blueberry Cultivation Techniques:

1. To buy blueberry seedlings, it is best to choose 2-3 year old seedlings. Small seedlings are cheap, adaptable, easy to transport and cultivate, and easy to grow.

2. Garden selection: the slope of the selected garden should be small, not more than 10 degrees; soil pH, optimal range; The content of soil organic matter shall not be less than 5%; The soil is loose and loose, well aerated and moist but not waterlogged.

3. Blueberry growth environment: blueberries can grow healthily in acidic media, blueberry growth for plots with soil pH value greater than that, and an appropriate amount of sulfur powder needs to be added to adjust soil acidity when deep turning. For plots with soil pH less than that, add an appropriate amount of lime.

Note that the amount of sulfur powder or lime should be added in an appropriate amount according to the soil structure and the actual pH value.

4. Blueberry likes moisture: water management is the most important factor to improve the survival rate and promote the growth of blueberry seedlings. Soil relative humidity is around 60% as well.

5. Blueberry sun-loving grip: the sun at 40 degrees in summer can not kill it, and it can tolerate 40 50 high temperatures in the surrounding environment during the growing season, as long as you give enough water in the morning. Without sufficient sunlight, blueberries will not be able to photosynthesize, and will grow stagnation, and even if they bloom, they will not bear fruit.

6. Weeding: Weeding is a very important part of blueberry orchard management, which can increase the yield by more than 1 time. In blueberry production, chemical herbicides are widely used.

This is because manual weeding is expensive and easy to damage the root system, especially in the cultivation of dwarf bush blueberries, due to the rhizome walking in tandem, after a few years, the whole orchard is connected, and manual weeding is not possible at all. Herbicides commonly used in blueberry orchards include diuron, simazine, chlorbenzine, 2,6 dichlorobenzene, glyphosate, paraquat, etc.

1. Soil: The optimal soil pH value is. The soil organic matter content is 8% to 12%, at least not less than 5%, the soil is loose, well aerated, moist but not waterlogged. For soil types that do not meet the requirements of blueberries, soil improvement should be carried out before planting to facilitate blueberry growth.

2. Management: 1Both spring planting and autumn planting can be used, among which autumn planting has a high survival rate, and spring planting should be early.

2.Fertilization (1) Common nutrient deficiency Iron deficiency and green deficiency: It is a common nutritional disorder in blueberries.

The main symptom is the loss of green between the leaf veins, and in severe cases, the leaf veins also lose green, and the symptoms of the upper leaves of the new shoots are more severe. The main causes of iron deficiency and green loss are high soil pH value, calcareous soil, and insufficient organic matter content. The most effective method is to apply the acidic fertilizer ammonium sulfate, which is even more effective if it is mixed with soil improvement.

Foliar sprays of integrated iron are more effective. Magnesium deficiency: the berry loses green between the leaf margins and leaf veins during the ripening stage, mainly on the new shoots and old leaves that grow rapidly, and then the green parts turn yellow and finally turn red.

Magnesium deficiency can be corrected by applying magnesium oxide to the soil. Boron deficiency: The symptoms are abnormal bud blooming, the apical bud withers, turns dark brown a few weeks after germination, and finally dies at the apex.

The main cause of boron deficiency is insufficient soil moisture. Adequate irrigation and foliar spraying of borax solution can be corrected. (2) Blueberry is a typical calcium-disgusting plant, which often leads to iron deficiency and green loss induced by excessive calcium when cultivated on calcareous soil.

Blueberries are oligotrophic plants with low levels of nitrogen, phosphorus, potassium, calcium, and magnesium compared to other fruit trees. Due to this characteristic, it is especially necessary to prevent excessive fertilizer in blueberry fertilization to avoid fertilizer damage. Another characteristic of blueberries is that they belong to ammonium-loving nitrogen fruit trees, which have a stronger absorption capacity for ammonium nitrogen in the soil than nitrate nitrogen.

When blueberries are planted, the soil has been mixed with organic matter or covered with organic matter, so blueberry fertilization mainly refers to top dressing. Farm manure is rarely applied in blueberry cultivation. It is mainly based on nitrogen, phosphorus and potassium fertilizers.

3.Watered blueberries belong to the fibrous root system, without the thick root system of the taproot, and its absorbent roots are like our hair strands, and the distribution is very shallow, generally distributed in the soil layer of 5-20cm. Therefore, it is also the fruit tree species with the worst drought resistance of all fruit tree species, and it is necessary to do not dry and water, and water thoroughly.

4.Pest control: leaf spot, canker, wilt and grubs (leeches), mole crickets and other pests and diseases may occur during the growth period of blueberries.

5.Overwintering protection Despite the strong cold resistance of bush blueberries and semi-tall bush blueberries, frost damage still occurs from time to time. The most important manifestations are overwintering strips and flower bud frost damage, which can freeze all the aboveground parts to death in special years.

Therefore, in the cultivation of blueberries in cold regions, overwintering protection is also an important measure to ensure yield. Tree covering: straw, leaves, sack sheets, straw woven bags, etc., can play a role in overwintering protection.

Blueberry is a small berry tree, which is distributed in Northeast China and North China, and requires acidic soil, which can be acidified to meet the local planting conditions.

Soil organic matter content and pH value are important factors for the survival of blueberry cultivation. Generally, it is required that the soil with an organic matter content of 5% and a pH value should be improved. When the organic matter content is less than 5%, river sand or sawdust, peat, rotten bark, etc. are mixed into the soil before planting.

When the pH of the soil (> or calcium content is too high, the pH value needs to be reduced. A large number of studies have shown that sulfur application is an effective measure to reduce soil pH. Sulfur powder is mostly used at home and abroad to lower the pH value.

The specific amount of sulfur should be determined according to different soil conditions and pH value. If the pH of the soil is too low (<, lime is often used to increase the pH.

English name: blueberry, meaning blue berry, belongs to the rhododendron family, bilberry plant. Originated in North America, perennial shrub small berry fruit tree. Because of the blue color of the fruit, it is called blueberry.

Blueberry fruit is rich in nutrients, which has the functions of preventing cranial nerve aging, protecting eyesight, strengthening the heart, anti-cancer, softening blood vessels, and enhancing human immunity, with high nutrients.

Among them, blueberries are rich in anthocyanins, which have the effect of activating the retina, strengthening vision, and preventing eye fatigue. It is also one of the top five healthy fruits recommended by the World Food and Agriculture Organization. And according to the research of scientists in the United States, Japan and Europe, regular consumption of blueberry products can also significantly enhance eyesight and eliminate eye fatigue.

Medical clinical reports have also shown that the anthocyanins in blueberries can promote the regeneration of rhodopsin in retinal cells, prevent myopia, and improve vision.

No, sawdust is usually added to the soil, which is very helpful for the growth of blueberries!

Potted blueberry seedlings After the blueberry seedlings are planted in pots, they are placed indoors in a ventilated place without sunlight for a week. After a week, it can be moved outside the balcony for normal maintenance. Watering management of potted blueberry seedlings Blueberries like moisture, especially in summer, and need to be given enough water every day.

But also pay attention to not stagnant water, otherwise the roots will rot. On rainy days in Shanghai, blueberries don't have to go indoors, no matter how heavy the rain is, as long as the flower pot has good water permeability, there is no problem. You can find that during the growing season, after several days of rain, the blueberry leaves are green and vibrant, and the new leaves are growing quickly.

When watering, add some edible white vinegar (recommended dosage: 3-5 degrees of vinegar, apply 500 ml every month, including half a tablespoon of vinegar), and fertilize should also pay attention to the application of acid fertilizer (ammonium sulfate).

1. Humus and pine needles: Blueberries select humus, pine needles, peat and grass peat, according to 10:5:

2. Pine phosphorus rot and peat: Blueberry soil formula can also use 3 parts of sandy soil, 3 parts of pine scale rot and 2 parts of peat to stir evenly, add some original soil to the soil, so that blueberries can adapt to the surrounding growth environment in a short period of time, and the prepared soil is extremely rich in nutrients and nutrients for the roots.

3. Perlite and sulfur powder: The appropriate amount of perlite and sulfur powder can be prepared according to 75% pine needle soil, 20% nutrient soil, 3% perlite and 2% sulfur powder, which will be more conducive to the absorption of blueberries.
