Do blueberries need to be fertilized when they bloom, and do blueberries need to be fertilized when

Blueberry flowering and fertilization can provide sufficient nutrients for blueberries and help blueberries bear fruit.

Potted blueberries precautions.

1. Time selection.

Potted blueberries can be planted all year round, and the best time is to buy them in the autumn to the next spring before budding, when the seedlings are easy to transport and simple to manage and plant. After planting in autumn, a small amount of flowering and fruiting can be done in the second year, and normal flowering and fruiting in the third year, and the peak fruiting period is after the fifth year, when blueberries are potted at home and managed properly, the fruiting period can be maintained for 35 years.

2. Soil requirements.

Blueberries, acidic, soft, loose and breathable, rich in organic matter soil, generally require the soil pH value, soil organic matter content is generally 8% 12%, family potted plants can buy common humus in the flower market, depending on their own conditions, add rotting moss or peat, sawdust, rotten pine bark and other organic matter, to add sulfur, once a month, until the leaves have a slight burn, fertilization should also pay attention to the application of acidic fertilizer, key tips: blueberry is a calcium-disgusting plant, do not add bone meal to the soil.

3. Containers. It is recommended to use a well-ventilated tile basin, followed by a sand basin, followed by a plastic basin, and it is not recommended to use a pottery or porcelain basin.

Because blueberries are fibrous roots, shallow root system, do not need to use large pots, avoid deep pots, small seedling pots are recommended to use 15cm pots, finished plants with 25cm pots, avoid small seedlings with large pots.

Fourth, climatic conditions.

A very important factor in ensuring the fruitfulness of potted blueberries is to ensure that the blueberries can withstand the following low temperature dormancy in winter, and the minimum temperature can vary depending on the variety.

5. Watering management.

The root distribution of blueberries is shallow, and they are more sensitive to water deficiency, so they should always keep the potting soil moist and not waterlogged, which is also different in different growing seasons of blueberries. In the vegetative growth stage, the most suitable water conditions can always be maintained to promote the plant to be strong, and the water must be appropriately reduced in the fruit development stage and before the fruit is ripe, so as to prevent too fast vegetative growth and fruit competition for nutrients, and after the fruit is harvested, the most suitable water ** is restored to promote vegetative growth. Mid-Autumn to late autumn to reduce moisture**, in order to facilitate timely entry into the dormant period, in order to maintain soil acidity, recommended dosage:

3 5 degrees of vinegar, apply 500 ml per month, to which add half a tablespoon of vinegar.

6. Fertilization. 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.

When blueberries are planted, the soil has been mixed with organic matter, so blueberry fertilization mainly refers to top dressing.

The suitable chemical fertilizers for potted blueberries are phosphorus pentoxide and ammonium sulfate. Excessive fertilization of blueberries can easily cause damage to the tree and even the death of the whole plant. Therefore, the amount of fertilizer should be cautious, depending on the soil fertility and the nutritional status of the tree.

In addition, blueberries should not be treated with nitrate fertilizers, such as ammonia nitrate, potassium nitrate, etc.

Blueberries bear small fruits, what fertilizer should be applied? to make it stronger.

Yes, blueberries must be fertilized during germination and flowering. Generally, sulfur-based compound fertilizer is used, the proportion is one thousandth, thin fertilizer.

Blueberry flowering does not need fertilization, so as not to make the plant fertilizer phenomenon, it is best before blueberry flowering, for it to apply a phosphorus and potassium fertilizer, so that the number of flowers Zheng potato increases, and after blueberry flowering, need to apply nitrogen, phosphorus and potassium compound fertilizer, is conducive to improve the fruit setting rate of the plant, and according to the soil moisture for blueberry watering.

Blueberries do not need to be fertilized when flowering, and it is better to fertilize before or after flowering when fertilizing, because fertilization during flowering is easy to cause blueberry flowering, so it is best to prepare nutrients for its top dressing before flowering.

Blueberry is a typical plant that likes to live in acidic soil, so if it lives in salinized land, there may be yellow leaves, to improve this phenomenon can be poured when the water is properly mixed with some ferrous sulfate solution, generally 30 days to add once, should not be over-applied.

When fertilizing, we should uphold the principle of thin cover fertilizer diligent application, can not be excessively applied or in order to pursue efficiency and speed and use thick fertilizer or raw fertilizer without ripening treatment, general fertilizer is mainly ammonium nitrogen fertilizer and organic fertilizer, appropriate use of nitrogen, phosphorus and potassium compound fertilizer, first fertilization and then watering to promote its absorption and utilization.

Blueberry is a typical light-loving plant, only in a more sunny environment its flowers can open enough and vigorous, its fruit can grow better, and after the top dressing should be properly watered, watering should be done thoroughly, so that blueberries can have enough nutrients to use, and finally produce high-quality fruits.

Blueberries do not need to be fertilized when they bloom.

It is better to fertilize blueberries before or after flowering, because fertilization during flowering is easy to cause blueberry flowering, so it is best to prepare nutrients for its top dressing before flowering.

Blueberry is a typical plant that likes to live in acidic soil, so if it lives in salinized land, there may be yellow leaves, to improve this phenomenon can be watered when properly mixed with some ferrous sulfate solution, generally 30 days to add once can, should not be over-applied.

When fertilizing, we should uphold the principle of thin fertilizer diligently, can not be excessively applied or in order to pursue efficiency and speed and use thick fertilizer or raw fertilizer that has not been matured, the general fertilizer is mainly ammonium nitrogen fertilizer and organic fertilizer, appropriate use of nitrogen, phosphorus and potassium compound fertilizer, first apply this rapid fertilizer and then watering to promote its absorption and utilization.

Blueberry cultivation method

1. Get seeds

Before planting blueberries, you must first obtain seeds, you can pick the fruit from the blueberry tree, and then use a knife to cut the blueberry, its center is the blueberry seed, take it out, wash it with water, and remove all the remaining pulp on the surface of the mess, so as to promote the seeds to take root and germinate better.

2. Soil preparation

After obtaining blueberry seeds, you need to choose a suitable soil for its growth, which can be mixed with humus, peat, and sand in the ratio of 5:3:2, this kind of mixed soil has strong permeability, and is rich in nutrients, which is more conducive to seed germination, and can make blueberries get sufficient nutrients.

3. Start sowing

After the blueberry seeds and soil are treated, you can sow seeds, prepare a tile pot and water moss with a breathable forest, then put the soil into the pot, sow the blueberry seeds on the surface, cover them with water moss, and finally wrap the pot mouth with plastic wrap and newspaper, leaving a few small holes on it for ventilation.

4. Seedling transplanting

Blueberry seeds can take root and germinate one month after sowing, at this time the seedlings should be dug out for transplanting, pay attention not to hurt the roots when digging, otherwise it will reduce the survival rate, choose the land that is sheltered from the wind and the sun when transplanting, replenish water once every 2-4 days after planting, and apply nitrogen fertilizer once a month during the growth period.

1. Fertilization principle: the requirements of various nutrients for blueberry growth and fruiting should be fully met, organic fertilizer should be applied, and the use of chlorine-containing fertilizers and chicken manure should be prohibited.

2. Fertilizer types: Commonly used fertilizer types include biogas slurry fertilizer, green manure, cake fertilizer, compost, manure and manure and other organic fertilizers.

3. Fertilization of young trees: apply fertilizer once in March and May after planting, apply 300 500g of organic fertilizer or 30 50g of potassium sulfate compound fertilizer, fertilize at 15 30cm from the roots of the tree in the first year after planting, and fertilize at 30 50cm from the roots of the tree in the second auspicious year after planting.

4. Fertilization of fruiting trees: apply basal fertilizer once a year to fruiting trees, and apply 5kg of well-rotted cow dung, manure and other organic fertilizers before germination from mid-September to February of the following year; If 1 top dressing is used, it can be applied within 1 to 2 weeks after flowering; If 2 times of top dressing are used, they can be applied at the end of the flowering and harvesting period, and the plant is applied potassium sulfate Shenlu compound fertilizer (nitrogen: phosphorus:

Potassium is 15:15:15) 150 300g.
