What do you need to grow blueberries and what conditions do you need to grow blueberries

The conditions required for blueberry cultivation are as follows:

1. Soil: The planting plot requires a deep soil layer, loose and fertile soil, an organic matter content above (a mass content of about 5-10% is appropriate), an active soil layer of more than 60cm, and a soil pH between.

2. Topography: The slope of the planting plot should not exceed 20°, and it is more suitable to flatland or mountainous land with a slope below 10°.

3. Climatic conditions: the absolute minimum temperature in the planting area should be above minus 15, and the average temperature should not exceed 500 hours during the period of January and February.

4. Irrigation water: The pH of the water used for irrigation should be below and the salt content in the water should not exceed 30mg kg.

Technical requirements for the cultivation of blueberries:

1. Seedling selection: When selecting seedlings, it is advisable to have 1-2 year old seedlings with a plant height of more than 30cm, a diameter of more than 5mm at the base of the main stem, and a developed root system, and at least 2 or more varieties need to be planted in the same plot (the ratio is 1:1, and the flowering period of the two varieties should be the same), and pollinate each other.

2. Planting hole: The size of the planting hole is 60 60 40cm (length, width and depth).

3. Planting: If it is a bare-root seedling, the planting time is from November to the end of February of the next year; If it is a container seed, it can be planted in any season, but it is better to plant in the dormant period; When planting, the seedlings are lifted upwards while covering the soil, and the soil is compacted to make the seedling roots in close contact with the soil, and the planting depth is slightly higher than the original soil marks of the seedlings in the nursery about 2-3cm.

1. Garden requirements.

The garden should be located on a flat terrain (slope 15). Blueberry is a strong light-loving plant, the garden should have sufficient light, there is no shade such as tall trees or buildings nearby, there is a need for irrigation water sources near the garden, drainage needs to be smooth, and the groundwater level is maintained at meters.

Second, the requirements of climatic conditions.

High-fill blueberries are generally resistant to low temperatures of -30 -25; Half-height blueberries can resist low temperatures of -38 -35; Dwarf blueberries can resist low temperatures above -40.

3. Soil condition requirements.

Before the establishment of the garden, it is important to do a comprehensive physical and chemical analysis of the soil to determine the content of various elements and nutrients in the soil and whether it is in a balanced state. In addition, it is a good idea to do regular leaf and soil analyses each year after planting to help determine the correct fertilization plan required for the orchard.

Precautions for blueberry planting:

1. Seedling quality: select 1 2-year-old seedlings with a plant height of more than 30 cm and a diameter of more than 5 mm at the base of the main stem, and advocate the use of container seedlings. The plant is required to be robust, the root system is developed, and there is no obvious damage.

2. Variety allocation: at least 2 varieties of the same type and consistent flowering period are planted in the same plot to facilitate mutual pollination, and the variety configuration ratio is generally 1:1 or 1:2 or 1:3.

The conditions for the cultivation of blueberries are as follows:

1. Climate. According to the climatic characteristics of China and the growth habits of different blueberry groups, the cultivation area can be roughly divided into four production areas: Changbai Mountain and Greater and Lesser Xing'an Mountains blueberry production areas, Liaodong Peninsula and Jiaodong Peninsula blueberry production areas, Yangtze River Basin blueberry production areas, and South China blueberry production areas.

2. Soil. Blueberry is suitable for sandy loam soil with loose drainage performance, soil pH value, the optimal soil pH value is, soil organic matter content is 8-12%, the optimal soil water level is 40-60 cm, and the soil is moist without water accumulation.

3. Moisture. Blueberry root distribution is shallow, sensitive to water deficiency, in most cases need to be irrigated on time according to soil conditions, river water, reservoir water or groundwater can be used as irrigation water sources, but to prevent the selection of high salt content and high pH water source irrigation.

4. Topography. Blueberries should be selected on flat or gently sloping land with relatively gentle terrain, although the mountainous land with a large slope is conducive to improving the quality of fruits, but it brings many inconveniences to field operations, and blueberries should be prevented from planting in valleys or low-lying plots to avoid frost damage during the flowering period.

Precautions for planting.

1. Fertilization method.

The fertilization method is generally furrow application, and the depth is 10 15cm. Fertilization can be done before budding in early spring, or once more at the ripening stage of the berries. The amount of fertilizer must be determined according to soil fertility and tree nutrition, and the principle is also less and not more.

2. Irrigation method.

Generally, when farmers grow blueberries, they will use their own deep well water as the main water source, but because blueberries are sensitive to water quality, and deep well water generally has a high pH value and high sodium and calcium content, the pH value can be adjusted to the left and right with sulfuric acid and then irrigated (the pH value can be measured with pH test paper).

How to grow blueberries:1. Prepare soil.

Blueberries like acidic soil, planting to choose humus, garden soil to prepare the cultivation base soil, and add vinegar residue or white vinegar to it, the pH of the soil is adjusted at about 5, if the nutrients in the soil are insufficient, you can also mix with well-rotted farm fertilizer to improve soil fertility.

2. Seedling selection and planting.

In the process of planting blueberries, it is necessary to choose seedlings with straight branches and good growth, and then use sterilized scissors to cut off the dry and damaged roots of the roots, put them in a cool place to dry the wounds, and then plant the seedlings in the prepared soil, compact the root soil and water it once to let the blueberries adapt to the environment.

3. Water and fertilizer management.

Blueberries avoid thick fertilizer, the demand for nutrients is small, during the breeding period, only need to fertilize blueberries during the fruit-hanging period and after fruit picking, mainly diluted nitrogen fertilizer, and blueberry roots are floating roots, avoid water accumulation, only need to moisten the surface soil when watering, to avoid water accumulation.

Blueberries were first popular abroad, and were often seen on the shelves as fruits in China, but it was not common to cultivate them as a family fruit tree. In recent years, with the increasing popularity of blueberries, many of our flower friends have begun to grow their own blueberry trees, and many of them have accumulated deep experience

About the amount of sunlight required for blueberries.

Blueberries are also slightly shade-tolerant, and generally speaking, blueberries can get full sunlight, unless the sun is really strong in summer, so they need proper shade. Therefore, if the sun is not good at home, it is not recommended to plant blueberries, because if you plant them, even if the fruit grows, the taste will not be very good.

About how to fertilize blueberries.

Blueberries are not a fertilizer-loving plant, but that doesn't mean they don't need fertilizer.

Before the blueberries are planted, I generally put down the bottom fertilizer, you can choose to use earthworm manure, rotten pigeon manure or chicken manure, the amount does not need to be much, put a good bottom fertilizer, and then cover the soil to ensure that the blueberry root system is more than 15 cm away from the bottom fertilizer, so that the roots find fertilizer, do not let the fertilizer find the roots.

Before germination in spring, when there are no leaves, I need to water liquid fertilizer once, and I mainly use liquid fertilizer or enzyme dilution in the compost box. Compost bin liquid manure and water 1:100 irrigation roots, 1:

200 spray branches. Enzymes and water are 1:50 irrigated roots, 1:

100 spray shoots.

After waiting for flowering, I won't fertilize. After the results, I will continue to water the liquid fertilizer mentioned above. Then the blueberry pot will be spread on the surface of the blueberry pot with a thickness of about 2 mm of earthworm manure or rotten pigeon manure, and there is no need to fertilize it in the future, the blueberry does not have high requirements for fertilizer, too high will hurt it, so that it is enough to give birth to high-quality blueberries.

1. * Soil selection.

The pH of blueberry cultivation soil should be between 4-5, which is not the acidity of most soils, and it is almost the lowest pH required in plants, so it is best to test the pH of the soil where you live beforehand, and you need to increase the acidity of the soil. In addition to being more organic*, use acidic fertilizers.

2. Buy seedlings.

A blueberry plant can be planted for more than 20 years, so it is best to go to a reputable store and buy healthy plants, about 2-3 years old, and do not buy leftover discounted plants at the end of the season.

3. Planting method.

When planting, it is necessary to dig a hole, preferably 66 cm deep, that is, a hole deeper than 50 cm and 60 cm wide. In this way, we can ensure that the soil will be well drained in the future. In addition, each plant is spaced 1 and a half meters apart.

If it is planted in rows, it is best to dig a ditch, just like planting a rose, and change them all* to ensure good drainage in the future. Because good drainage is very important for blueberries.

4. Watering matters.

Growing blueberries requires full sunshine and requires 3 6 cm of water per week, so if it doesn't rain, water it well every 4-6 days, preferably from the ground. Generally, a kind of seepage pipe is placed on the ground for watering.

5. Fertilization management.

Don't fertilize when you first plant it, and only once a year is enough, because blueberries are very sensitive to too much fertilizer and even have a counterproductive effect. Fertilize before germination begins in the spring (before the leaves grow), and if you are planting alkaline soil, make up with acidic fertilizer. Among the organic fertilizers, blood fertilizer, fish fertilizer, and animal manure* can all be supplemented with nitrogen fertilizer.

Bone fertilizer and seaweed fertilizer are supplemented with phosphate fertilizer and potassium fertilizer. These are supplementary fertilizers, and they are slow fertilizers, which will slowly decompose into the soil, if you want to top dress, you can use organic fertilizer at the end of the spring season.

6. Pruning management.

It is best not to let it bear fruit for the first two years of planting. Therefore, in the spring, when the flowers are almost gone, they are plucked first to avoid fruiting. In this way, the plant can concentrate nutrients to produce more robust branches (lay a good foundation), and in the future, the plant will be strong and the conditions for fruiting will be better.

For the first few years there is no need to prune, wait until about the first.

Pruning should begin in four or five years, preferably towards the end of winter (as with roses), before the new shoots begin to sprout in early spring. The principle of pruning is to prune all the branches that are older than six years to the ground, and at the same time cut off the excessive branches in the interior, or the branches that grow crosswise, so that the middle part can get sunlight. In addition, if there are branches that are too low, the branches that droop to the ground should also be cut off to prevent the fruits from touching the ground in the future, which is easy to attract insects and ants.
