Generally, it is planted in spring in northern areas, and improper management in autumn and winter is prone to freezing injury. Spring planting is usually in March-April. Generally, 2 ~ 3-year-old seedlings are selected. On the one hand, saplings are cheap; on the other hand, they are adaptable and easy to plant.
It is best to choose clay pots for planting blueberries. Pottery pots are breathable and cheap, but the disadvantage is that black ash is not very beautiful. If you can't buy pottery pots, you can choose pottery pots, followed by purple sand pots and plastic pots. Never use glazed porcelain pots. As for the size of the pot, for 2-3-year-old seedlings, choose a pot with a diameter of 25-30 cm, and avoid large pots for small seedlings. When you grow up, change a big basin. Mature plants of 4 ~ 5 years, of course, the bigger the better.
Blueberries can grow healthily in acidic medium, and the pH value of cultivated soil is between 4 and 5, which is most suitable for blueberry growth. This problem has troubled many blueberry lovers, because the pH value of pastoral soil is generally between 6 and 7, and even the acid soil sold in the flower and bird market has a minimum pH value of between 5.5 and 6.
After planting blueberry seedlings in a pot, put them in a ventilated place indoors to avoid light for a week. This process is called slow seedling. You can move outside the balcony for normal maintenance after one week.
Blueberries like humidity, especially in summer, so they need to be given enough water every day. But be careful not to accumulate water, otherwise the roots will rot. Blueberries don't have to go indoors on rainy days in Shanghai. No matter how big the rain is, as long as the flowerpot has good water permeability, there is no problem. You can find that in the growing season, when it rains for several days in a row, the leaves of blueberries are bright green and full of vitality, and new leaves sprout soon.
Blueberries are sunny, and the 40-degree sun won't kill them in summer. In the growing season, as long as they are given enough water in the morning, they can tolerate the high temperature of 40℃ ~ 50℃ in the surrounding environment. If there is insufficient sunshine, the growth of blueberries will stagnate, and even if they bloom, they will not bear fruit.
Blueberries need refrigeration. The so-called cold storage means that blueberries usually take x hours to achieve normal flowering and fruiting. Question 2: When is the best time to grow blueberries? Haha, I planted eight. I know autumn and winter are the best, and the average temperature is 18 degrees. If the sun is not too big, spring is fine. I think it's Shanghai. It's usually like February.
Question 3: How to plant blueberry trees? Balcony planting:
Planting is not difficult. Blueberries like acidic soil, with little fertilizer, sunny and humid, and need to store cold energy. Below I will introduce the planting method in detail and explain several characteristics of blueberries in detail.
To buy blueberry seedlings, it is best to choose 2 ~ 3 years old seedlings. On the one hand, saplings are cheap; on the other hand, they are adaptable and easy to plant.
It is best to choose clay pots for planting blueberries. Pottery pots are breathable and cheap, but the disadvantage is that black ash is not very beautiful.

Question 4: Do blueberry trees have thorns? In what month is it usually planted and bears fruit? Blueberries have no thorns. Plant in June+February-March, 5438, and the variety will be in the morning and evening. Generally, fruits are picked from late May to July.
Introduce a group of special fruit tree treasures
1. Hongxiangguo is a perennial vine fruit tree of Cucurbitaceae. The fruit of that year was bright red, with the sweetness of sesame and walnut. Single fruit 10-30g, yield per mu 1500kg. The benefit is more than 50 thousand, and it has been harvested for several years. It is easy to grow pipes and loofahs, and the places where watermelons and gourds can be planted are suitable for planting in all seasons, and flowers and fruits are constantly in greenhouses.
2. The white kiwifruit cultivated by the Provincial Academy of Agricultural Sciences has pink flowers, white fruit, green flesh, sweet and delicious taste, single fruit of 80- 130g, and the VC content exceeds that of any kiwifruit variety, which has anti-cancer effect. In the second year after planting, the fruit set is 15-30kg, planting 1 10 plants per mu, and picking the fruit.
Third, Sanhong pear pear trees generally have white flowers, while Sanhong pear trees have red flowers. Not only flowers and leaves are red, but also young fruits to mature fruits are red. Therefore, it is called Sanhong pear, with an average fruit of 260 grams, thin skin, sugar content 12.2% and good quality. Strong adaptability, resistance to leaf rust, easy management, planting for 2-3 years, maturing in June-July as early as possible, with a yield of 5000 kg per mu.

Planting technique
It is best to choose clay pots for planting blueberries. Pottery pots are breathable and cheap, but the disadvantage is that black ash is not very beautiful. If you can't buy pottery pots, you can choose pottery pots, followed by purple sand pots and plastic pots. Never use glazed porcelain pots. As for the size of the pot, for 2-3-year-old seedlings, choose a pot with a diameter of 25-30 cm, and avoid large pots for small seedlings. When you grow up, change a big basin. Mature plants of 4 ~ 5 years, of course, the bigger the better.
Blueberries can grow healthily in acidic medium, and the pH value of cultivated soil is between 4 and 5, which is most suitable for blueberry growth.
This problem has troubled many blueberry lovers, because the pH value of pastoral soil is generally between 6 and 7, and even the acid soil sold in the flower and bird market has a minimum pH value of between 5.5 and 6.
Blueberries need refrigeration. The so-called cold storage capacity means that blueberries usually take x hours to blossom and bear fruit normally, or when the calcium content is too high, the pH value needs to be lowered. A large number of studies show that sulfur application is an effective measure to reduce soil pH value. Sulfur powder is commonly used at home and abroad to reduce pH value. The specific sulfur application amount should be determined according to different soil conditions and pH values. Soil pH is too low (>
Question 6: How to plant blueberry trees The planting method of blueberry trees is as follows:
1, planting seedlings:
Generally, it is planted in spring in northern areas, and improper management in autumn and winter is prone to freezing injury. When planting seedlings, fill some wet acidic peat soil or pre-prepared planting soil in the pit, then plant seedlings and lay roots, so that the added mixed peat soil surrounds the roots of seedlings, and finally cover the soil until it is flush with the ground.
2. Surface coverage:
After planting, cover the surface of the planting hole with a layer of straw, humus, bark, sawdust, etc. Or spray a new high-fat film, which can adjust the ground temperature, prevent surface water from evaporating, keep soil moisture and promote root growth.
3, fertilization:
Blueberry is a plant sensitive to fertilizer. In excessive fertilization, the high concentration of soil alkali will damage the roots and cause plant death. Pollution-free cationic surfactant Wang Cuihua No.2 can be used to promote flowering genes and make fruit trees blossom and bear more fruits. Spray Zhuangguodiling in time to thicken the pedicel of fruit and increase nutrient transport in young fruit stage.
4. Overwintering protection:
Although dwarf blueberries and semi-tall blueberries have strong cold resistance, freezing injury still occurs from time to time. The main manifestations are bolting and flower bud freezing injury in winter, and all the aboveground parts can be frozen to death in special years. Therefore, wintering protection is also an important measure to ensure the yield in blueberry cultivation in cold regions. For example, piling snow to prevent cold, coloring trees to protect them and so on.
Question 7: How do blueberry saplings grow blueberries as shrubs? Each cluster has 25-30 fruiting branches, which blossom and bear fruit in the second year, but the yield is small. In the third year, there is an appropriate rate of return, and in the fifth year, it enters a high-yield period. Its life span is 50 years, the average yield per plant is 3-6 kg, and the average fruit weight is 2 grams. Generally, about 300 plants are planted per mu, and the average yield is 1500-2000. First, choose garden planting 1. The pH value of the soil at the site of garden selection and land preparation is 4 ~ 5.5, and the optimum pH value of the soil is 4.0 ~ 4.8. The content of soil organic matter is 8% ~ 12%, at least not less than 5%. The soil is loose, well ventilated and moist, but there is no water accumulation. If the local rainfall is insufficient, there needs to be enough water. In order to solve the problem of water accumulation in summer, strip terraces can be used for cultivation. After garden selection, deep ploughing should be combined with pressing green manure 1 year before planting, and the depth should be 20 ~ 25 cm, and deep ploughing should be done well. If there are many weeds, herbicide can be sprayed 1 year in advance to eliminate weeds. For soil types that do not meet the requirements of blueberries, soil improvement should be carried out before planting to facilitate the growth of blueberries. Adjusting the soil pH value to be too high is an important factor limiting blueberry planting. Too high pH value often leads to iron deficiency, poor growth, reduced yield and even plant death. When the pH value is greater than 5.5, it is necessary to apply sulfur powder or aluminum sulfate to reduce the pH value. Sulfur powder should be applied before planting 1 year or at least in the same year after planting, but it generally does not work in that year. For example, in dark brown forest soil, the effect of reducing pH value 1 cm requirement 1 g sulfur powder per square meter of soil layer can last for more than 3 years. Other types of soil can use this amount. Scatter sulfur powder evenly into the whole garden soil according to the calculated application amount, and dig deeply 15cm and mix evenly. If aluminum sulfate is used, the dosage is 6 times that of sulfur powder. In addition, adding acid peat to soil and applying acid fertilizer to cover sawdust and rotten bark can reduce pH value. If sulfur powder and peat are used together, the effect is better. When the soil pH value is lower than 4, blueberries will be poisoned due to excessive heavy metal elements, leading to poor growth and even death. At this time, it is necessary to raise the pH value and often adjust it with lime. When the soil pH value is 3.3, the application of 8t lime per hectare can increase the pH value to above 4 and increase the yield by 20%. Improve soil structure and increase organic matter When the organic matter content of soil is less than 5%, blueberry is fibrous root because the soil is hard and sticky, which is not conducive to root development, so it is necessary to apply more organic matter or river sand to improve the structure. Commonly used sawdust, peat, rotten bark or rotten moss, mixed with soil when planting. 2. Fixed planting date (1): Spring planting and autumn planting can be used, among which autumn planting has a high survival rate and spring planting is earlier. (2) Plant spacing: 2m×2m or1.5 m× 3 m is commonly used for rabbit eye blueberry; High clump blueberry1.2m× 2m; ; Dwarf blueberry (0.5 ~1) m×1m. (3) Pollination tree configuration: Rabbit-eye blueberry is not self-flowering, so pollination trees must be configured, and high-bush blueberry varieties can be selected. High-bush blueberry and short-bush blueberry have higher self-pollination rate, but pollination trees can also improve fruit quality and yield. The ratio of main cultivated varieties to pollinated varieties is 1∶ 1 or 1∶2. Second, soil, fertilizer and water management technology 1. Soil management Blueberry root system is shallow and slender, without root hair, which requires loose and well-ventilated soil conditions. (1) Clear tillage is usually used to plant high clumps of blueberries on sandy loam. The suitable cleaning depth is 5 ~ 10 cm. The dark brown forest soil below 23 ~ 30cm in Changbai Mountain area is often a cohesive loess layer. If ploughing is too deep, the loess will turn to the upper layer, which is not conducive to root development. Therefore, the height of blueberry cultivation tools is generally less than 15cm. The cleaning time can be carried out from early spring to August, and it is not conducive to wintering after autumn. (2) Planting grass between rows and using herbicides between rows. Compared with clear tillage method, green grass method is beneficial to increase production, and has the advantages of obviously maintaining soil moisture and facilitating mechanized operation. The disadvantage is that it is not conducive to controlling blueberry fruit rot. 2. Fertilization (1) Common nutrient deficiency ① Iron deficiency chlorosis is a common nutritional disorder in blueberries. The main symptom is green veins, even green veins in severe cases, and the symptoms of upper leaves of new shoots are more serious. The main causes of iron deficiency chlorosis are high soil pH value, calcareous soil and insufficient organic matter content. The most effective method is to apply acid fertilizer ammonium sulfate, and if acid peat is mixed with soil, the improvement effect will be better. Spraying 0. 1% ~ 0.3% integrated iron on the leaves is better. ② When magnesium-deficient berries mature, the leaf edges and veins lose their green color, mainly appearing on the old leaves with fast growth of new shoots, then the green part turns yellow and finally turns red.

Question 8: When do you plant blueberries? What cultivation techniques are introduced? Blueberry field seedlings are suitable for planting in spring and autumn, and it is best to plant them in spring in northern China. If they are planted in autumn and not properly managed in winter, they are vulnerable to freezing injury. Spring sowing should be done before spring sowing germinates. Southern China can be planted in autumn, usually during the period of11~ 65438+February when the growth stops and enters the dormant period. If it is a container seedling, it can be planted all year round, but care should be taken not to hurt the roots when planting.
In addition, the planting time should also consider the problem of blueberry varieties. It is best to start planting high-irrigation blueberry and rabbit-eye blueberry varieties before the plants germinate in early spring. Some evergreen varieties can be planted at any time, but late winter and early spring are also ideal planting time. This is helpful for the development and growth of roots and buds.
In order to obtain higher yield and economic benefits, blueberry varieties with high irrigation are replanted every 6-8 years after planting. However, the rabbit eye blueberry varieties are replanted every 10 ~ 12 years after planting.
Question 9: Blueberry seedlings took more than two years to bear fruit, but the yield was small.
Question 10: How often do families plant blueberry trees and water them? Blueberries like light and are drought-tolerant. It is best to put it in a bright and ventilated place on the balcony. When the soil is dry, it can be watered thoroughly. If the soil is not dry, it is better to add some nutrient solution when watering with fat water. You can also bury several compound fertilizers in the pot. How much time is hard to say, depending on the size of the basin and the speed of soil drying.
