Planting methods and key points of cultivation and Management of potted Blueberry

Blueberries, also known as blueberries, benedicts, persimmons, etc., are low shrubs of the blueberry genus of the rhododendron family. They are mainly potted in increasingly compact cities with an inch of land, and almost all blueberries are suitable for potted plants. But balcony potted plants should pay attention to choosing the right varieties of height to facilitate the movement of flowerpots. Let's take a look at the planting methods of potted blueberries.

Basin soil allocation

Blueberry can grow healthily in acidic medium, and the pH of cultivated soil is between 4.5 and 5.5, which is the most suitable for blueberry growth. The pH value of garden soil is generally between 6 and 7, and the lowest pH value of acidic soil sold in flower and bird market is between 5.5 and 6. In general, sulfur powder is used to adjust acid in the planting base, adding one gram of sulfur powder per liter of soil can reduce the soil PH value by 1, and some varieties do not require much acidity, but they are not as good as those planted in acidic soil.

adequate manuring

Blueberries disrelish fat and calcium, generally in the initial stage of planting with mature cattle, sheep, rabbit dung or rotten leaf soil can be, disrelish fat but not topdressing, so in the future planting a small amount of topdressing is still necessary, avoid big fat. Nitrogen, phosphorus and potassium compound fertilizer or ammonium sulfate solution with a content of 1:1:1 is generally used. Also pay attention to stay away from things that contain calcium, such as some people often put eggshells in flowerpots.

Timely watering

Blueberry root distribution is shallow, like wetting, timely watering is very necessary. The water source and water quality of blueberry watering should be paid attention to. Deep well water generally has high pH value and high contents of sodium and calcium, and long-term use will affect the growth of blueberry. PH value can be adjusted to 4.5-5.5 with sulfuric acid during irrigation, but acid water should be irrigated again at intervals of 3 times. Proper watering can make blueberries resistant to high temperature and safely spend the summer.

Illumination control

The demand for light of blueberry is the same as that of other plants. Compared with the same variety, if the light intensity is not enough, there will be fewer flower buds and lower fruit quality. For orchards with high cultivation density, proper pruning is conducive to photosynthesis. For the balcony terrace family, the light management of blueberries is simpler than the orchard, but should pay attention to ventilation.

Cold prevention management

Blueberry dwarf bushes and half-height bushes have strong cold resistance, but due to different low temperatures in different places, freezing injury still occurs in extreme weather, the most important of which is frost injury at the ends of branches and flower buds overwintering in the open air, or even the whole plant is frozen to death. Therefore, blueberry cultivation and overwintering protection are also important measures to increase yield in cold areas.

Key points for planting potted blueberry seedlings (practical information)

Many fruit friends are using the method of cultivating fruit trees to cultivate blueberries, which eventually leads to the death of blueberries. There are three main points for planting potted blueberry seedlings, namely, the permeability of cultivated soil, the ph of cultivated soil, and the organic matter of cultivated soil.

1. The root system of blueberry is fibrous, its penetration is weak, it is not tolerant to fertilizer, waterlogging and drought. Therefore, the soil needs to be loose and permeable. Just the soil to keep it damp.

two。 Blueberry requires the cultivated soil to be acidic, PH 4.2-5.8, so the soil requires the addition of pine needles, broken pine bark, moss, weeds, rotten leaves, broken crop straw and so on. These organic matter can produce organic acids when they rot, which can maintain the acidity of the soil.

3. Organic matter is necessary for the growth of blueberries. Although the yield of blueberries is not positively correlated with the content of soil organic matter, blueberries grow poorly when the content of organic matter in the soil is less than 8%. When the organic matter in the cultivated soil is more than 8%, there is no need to apply fertilizer to cultivate blueberry.

The ratio of organic matter to soil in cultivated soil is 2:1 or 3:2

The above three items can be satisfied when 2:1 or 3:2 organic compounds such as pine needles, broken pine bark, moss, weeds, rotten leaves and chopped crop straw are added to the cultivated soil. In this way, blueberries generally do not cause problems in cultivation.

Physiological acid fertilizer is better for blueberry fertilization: ammonium sulfate, potassium sulfate, diammonium, potassium sulfate ternary compound fertilizer can be used. Fertilization requires sparse, thin, light, less application, not diligent application.

Key points of seedling selection of blueberry potted plant

Potted blueberry has gradually become a plant planted by many flower friends on the balcony, not only can be used for ornamental, its fruit also has a certain health effect, very suitable for planting in their own balcony or courtyard. Before raising potted blueberries, it is very important to choose a good seedling.

Blueberry potted plant

However, there are some difficulties in blueberry maintenance, so there are several requirements that should be paid attention to when choosing blueberry seedlings:

1. In the selection and purchase of seedlings, we must first choose the right variety. One variety is the key to the fruit of the fruit tree. When cultivating blueberries, we must choose and buy large fruit varieties, that is, blueberry varieties suitable for local cultivation.

2. It is best to choose large seedlings for more than two or three years, with 3 to 5 branches, more than 30 cm without diseases and insect pests, complete roots, no mechanical damage, and strong seedlings.

3. It is best to choose the variety that buys nutrition bowl to raise seedlings, this kind of seedling has a high survival rate, and can be cultivated at any time in spring, summer and autumn, which is not limited by the season.

4. Before the seedlings are bought back, the cultivation soil must be prepared in advance and the acidity and alkalinity must be adjusted. Because blueberry is a perennial fruit tree, it can grow for several decades at one time, so it is necessary to adjust the soil for the first time when planting, so as not to hinder the growth in the future.
