How big pot should you use for three year old blueberry seedlings

Depending on the blueberry root system you get! The root system is developed, and it is generally enough to use an ordinary flower pot of 30 caliber, which is too large and is not conducive to the maintenance of water and fertilizer.

Blueberries are potted with how deep the pot.

Answers. 1.If you want to grow blueberries in a pot, use a pot about 40 cm deep.

2.It is a shallow-rooted plant with a high locust flower, and if the pot is too deep, it will affect the root growth.

3.The best material for the flower pot is clay pot, because it has good air permeability, which is good for the breathing and growth of blueberry roots.

4.Second, you can also choose a silver purple sand basin or a plastic basin, and do not use a glazed porcelain basin.

Three-year seedlings are just right, because blueberries can flower and bear fruit normally in three years, and they can enter the full fruiting period in about five years. It is the best time for bonsai.

How to care for potted blueberries?

1.Potting soil selection.

2.Illumination. Light is essential for the growth of blueberries, if the long-term lack of light will lead to fewer flower buds on the plant, affecting the quality of the fruit, and at the same time, it can be combined with proper pruning, which is conducive to the photosynthesis of potted blueberries. For balcony potted blueberries, attention should also be paid to ventilation.

3.Temperature. Potted blueberries are a very important factor in ensuring fruitfulness, as they are subjected to the following low temperatures of dormancy in winter, with the lowest temperature varying from variety to variety. For example, as a flower ornament, low temperature restrictions cannot be used.

4.Watering. When watering potted blueberries, you need to pay attention to the water source and water quality, because the pH value of the deep well water is usually high, and the sodium and calcium it contains are high, and long-term use is not conducive to the growth of blueberries, so you can use sulfuric acid to adjust the pH value of the deep well water to about about 10 times and then water, generally should be irrigated about 3 times and then watered with acid water.

5.Fertilize. Blueberries can not be fertilized frequently, and a certain amount of Vosch Woye microbial agent can be added to the soil when planting. In the later stage, attention should be paid to the application of phosphorus fertilizer as little as possible, of which acid fertilizer is the main one.

It is best to choose 3-4 years old blueberry seedlings for planting blueberry seedlings. At this stage, blueberry seedlings have a gradual and stable mass production period, and their resistance to pests and diseases is relatively strong.

Planting: blueberry planting in spring, autumn and winter, blueberry planting plant row spacing is commonly used, rabbit eye blueberry self-flowering and the special structure of blueberry flowers are not conducive to full pollination, in order to improve the quality and yield of blueberries need to be configured with different varieties of mixed planting, if conditions permit, bees can also be stocked with insects to assist pollination.

1. Soil management: The root distribution of blueberries is shallow, and slender, without root hairs, so the soil is required to be loose and well aerated. Clearing the tillage.

Ploughing can be carried out from early spring to August, and it is not good for wintering after autumn. Highbush blueberries are cultivated on sandy loam soils, and clearing is commonly used. The depth of tillage is 5 10cm, and it is easy to damage the root system if it is too deep.

Grass method. Grass is grown between the rows. Compared with the clear tillage method, the grass method is also beneficial to increase yields, and has the advantages of maintaining soil moisture and facilitating mechanical work.

Soil cover. Soil mulching is widely used in blueberry production, which has many effects such as increasing soil organic matter, improving soil structure, regulating and maintaining soil moisture, reducing soil pH value, and controlling weeds.

2. Fertilization: It is recommended to use organic fertilizer. The excessive use of chemical fertilizers in China's farmland has caused serious pollution, and eventually the land yield has been reduced or even extinct.

Type of fertilization. The application of nitrogen, phosphorus and potassium compound fertilizer mixed organic fertilizer has a better effect than that of single fertilizer; The ratio of nitrogen, phosphorus and potassium fertilizer should be 1 1 1; It is better to apply ammonium nitrogen fertilizer such as ammonium sulfate, and nitrate nitrogen fertilizer should not be applied; Blueberries are sensitive to chlorine, so do not use chlorine-containing fertilizers such as ammonium chloride and potassium chloride.

Fertilization method and period. Tall bushes and rabbit eye blueberries can be cast in furrows, and the depth is 10 to 15 cm. Fertilization is done in early spring before bud break, but it can also be applied again once during the ripening of berries.

Amount of fertilizer. Excessive fertilization can easily cause damage to the blueberry tree or even the death of the whole plant, so the amount of fertilizer should be determined very carefully, and it must be determined according to the soil fertility and the nutritional status of the tree.

3. Irrigation: Blueberry root system is shallow and likes moisture, so timely irrigation is very necessary. Blueberry irrigation needs to pay attention to the water source and water quality, deep well water is generally high pH value, and high sodium and calcium content, long-term use will affect the growth and yield of blueberries, you can use sulfuric acid to adjust the pH value to about about 1 time and then irrigate, but should be about 3 times of irrigation and then irrigate acid water.

Summary. Hello, I'm glad to answer for you, the planting density of blueberries varies depending on the variety, topography and cultivation technology, generally speaking, the planting density of potted blueberries per square meter is 2-3 plants is more appropriate, and the height of three-year blueberry seedlings is generally about 60-80 cm, and the width is about 50-60 cm. Therefore, based on the minimum density of 2 square meters, 1200 square meters can grow 2400 potted blueberries.

Three-year-old blueberry seedlings are transplanted into the nutrient cup, and how many can be placed in 1200 square meters.

12 meters wide and 100 meters long.

Hello, I'm glad to answer for you, blueberry seedlings transplanted into the nutrition cup need a certain amount of growth space and nutrients** to grow healthy and rough. In general, each blueberry seedling needs to use a nutrient cup with a capacity of about 18 liters, and each nutrient cup needs to occupy a certain growth space, so in practice, it is necessary to plan the planting density according to the specific situation. Assuming you are using cups with a capacity of 18 liters and each cup occupies square meters, then 1200 square meters of planting area can be placed:

1,200 = 12,000 cups If you plant one blueberry seedling per cup, you can grow 12,000 blueberry seedlings. Of course, this is only a rough estimate, and the actual planting density needs to be reasonably planned according to various factors such as blueberry varieties, cultivation management and service technology. The above is my reply, I hope it can help you!

Use well-drained and breathable pots, and use humus, garden soil, and sand to prepare the base soil. 3. Planting: Soak the blueberry seeds for one day and then sow them in the soil.

4. Maintenance: After planting, water a piece of air search permeable water, and cover with plastic film to keep warm.

1. Planting time

There are many different varieties of blueberries, including varieties suitable for cool and cold environments, varieties suitable for warm environments, and the best time for planting different varieties is not the same, it is best to choose according to the variety, if you can't distinguish then you can plant in spring and autumn, these two time periods are more broad.

2. Preparation of potting soil

Blueberries are suitable for planting plants in acidic environments, and will grow and develop more rapidly and vigorously in suitable soil, so it is necessary to use humus, garden soil and sandy loam soil for uniform mixing and preparation to ensure that blueberries can be in a relatively loose and fertile environment, with a more suitable substrate for rooting.

3. Planting techniques

Prepare the ripe blueberry fruit, then take out the seeds from the fruit, brush off the pulp juice on the top, etc., to ensure that the surface of the seeds does not leave the pulp juice to avoid rotting, then soak it in clean water for a day, and then take it out and plant it in the prepared loose and fertile soil.

4. Maintenance work

After planting, it should be watered once, this time the watering should be fully watered, so that the soil is in a completely moist state, but be careful not to leave stagnant water, and then cover it with a thin layer of soil or plastic film, and put it in a place with sufficient scattered light to maintain, it only takes about 30 days to survive.

Hello, it is a pleasure to serve you and give you the following answer: how thick blueberry seedlings are in 8 years is a common problem, mainly due to the poor growth environment of blueberry plants. The solution to this problem is as follows:

1.First of all, make sure that the blueberry plant grows in a good environment, keep the soil moist, avoid over-drying the soil, and maintain the appropriate pH of the soil. 2.

Secondly, it is necessary to apply fertilizer regularly to provide the nutrients needed by the plants and promote the healthy growth of the plants. 3.Finally, blueberry plants should be pruned regularly to promote the growth of the plants and make them more compact.

The above are the methods and practices to solve the problem of blueberry 8-year-old seedlings, I hope to help you. Personal tip: Provide a good environment for your blueberry plants to grow, and apply regular fertilization and pruning to maintain healthy growth.

For planting blueberries in pots, it is best to choose mud pots. The mud pot is breathable, cheap, and the disadvantage is that the black gray color is not very beautiful. If you can't buy a clay pot, you can choose a clay pot, followed by a purple sand pot, a plastic pot, and don't use a glazed porcelain pot.

As for the size of the pot, 2 3 years old seedlings, choose a pot with a diameter of 25 to 30 cm, and avoid small seedlings and large pots. When you grow up, you can change the big pot. 4 5 years old mature plants, of course, the bigger the better.

Blueberries can only grow healthily in acidic media, and the pH value of the cultivation soil is between 4 and 5 for blueberry growth.

This problem bothers many blueberry lovers, because the pH value of pastoral soil is generally between 6 and 7, even if the acidic soil of the flower and bird market **, the pH value is the lowest.

Blueberries need to store cold energy. The so-called cold storage capacity is that blueberries generally need x hours to achieve normal flowering and fruiting, and the specific time varies depending on the variety, so China's Hainan is not suitable for planting blueberries. If the cold storage capacity is insufficient, the blueberries can also bloom normally, but do not bear fruit.

Therefore, if you grow blueberries on the balcony in the Gangnam area, you don't need to move back indoors in winter.

Blueberries do not have high requirements for fertilizer, and big fat will hurt it instead. There is a certain amount of humus in the medium, which can basically meet the growth needs of blueberries. Of course, if you want to eat your own blueberries, you still need an appropriate amount of top dressing.

It is recommended to apply "Hua Duoduo", 1 gram with 1000 grams of water, once every 7 to 10 days. This fertilizer is relatively warm, and even if it is used in excess, it will not burn the roots.

I raised 500 blueberries for four years, and this year it started to bear fruit. My blueberries are a Canadian variety – Midon. Every winter, the soil is kept warm by the soil cultivation method for winter, and the winter soil is removed in mid-February in spring, and the slender and weak branches are cut off in late February.

For fertilization, in March and April, use 20% farmhouse fertilizer + 40% peaty soil + appropriate amount of nitrogen fertilizer. It will bloom and bear fruit in May, so be careful about pollination.

The 4-year-old blueberry seedlings are mainly cut off the crown, but the consequences can be moderate. Here's how to prune:

Pruning at the young tree stage. In this period, the main focus is on flower bud removal, and the policy is to cut the canopy, increase the number of branches, and promote root development. In the spring of the second and third years after planting, the strong branches were thinned, and the crown was still cut in the first year, but the consequences were moderate.

1 Generally, the third year of blueberry plant production should be disciplined below 1 kg, with the main consequences of strong branches.

Mature tree pruning. At this time, the pruning master should discipline the height of the tree, improve the light conditions, mainly thin the branches, and remove the overly dense branches, thick branches, diseased branches and root tillers. The root potential of blueberry is relatively close, and the varieties are weak and strong when thinning branches; Stripped varieties remove the core stem, open the skylight, and leave medium branches.

The best consequence of large branches is 5 to 6 years old, beyond which it is necessary to retract and renew in time. Powerful branches erase the flower buds and make them stronger. Adult trees have a large number of flowers, so they should cut off 1 flower bud, and leave 2 or 3 flower buds for each strong branch.
