Can you give blueberries foliar fertilizer at 26 to 27 degrees Celsius?

I think it's perfectly fine to apply foliar fertilizer to blueberries at this temperature, and as long as it doesn't rain on this day, I think it's okay to apply foliar fertilizer at this temperature.

If the temperature is between 26 and 27 degrees, you should not apply foliar fertilizer to blueberries. It is best to have a temperature of around 20 degrees Celsius in the morning or afternoon when the temperature is low.

This 26 27 can be used to liquid blueberries, and there is no problem with fattening.

If it is 26 to 27 degrees, it should be possible to fertilize the foliar surface of blueberries. This temperature is actually the most suitable.

Temperatures 26 to 27 can be applied to blueberries with foliar fertilizer. Be sure not to hit it when you're in the sun, preferably in the morning or evening.

You can hit it in moderation.

During the growing season, if you want to top the blueberries, you don't need to apply foliar fertilizer to them. If top dressing is not applied, some foliar fertilizer containing nitrogen can be applied to it. During the flowering and fruiting period, you can change to some foliar fertilizers containing phosphorus and potassium, such as potassium dihydrogen phosphate.

Before application, it needs to be diluted with water to avoid damage to the plant due to the thick fertilizer.

The temperature is 26 to 27 degrees, and you can fertilize the foliar surface of blueberries without any problems.

The temperature is a little higher, but this stage can still be controlled, as long as it is not above 29 30, you can apply fertilizer.

Temperature 26 to 27 Can you give blueberries foliar fertilizer? At this temperature, you should be able to fatten blueberries.

Temperature requirements for blueberry growth: absolute minimum temperature -15, average temperature of more than 500 hours in January and February.

Garden selection: The orchard should be selected in an area without air and water pollution, convenient transportation, convenient water source and electricity. It is required to stay away from cities and places where people are relatively concentrated, away from roads and railways, to prevent pollution from heavy metals (lead, mercury, etc.), sulfur dioxide, arsenic, fluoride, cyanide and so on.

Flat land and gentle slope land with a slope of less than 6° are directly dug and planted in planting holes; In mountainous and hilly areas with a slope of 6° 20°, high-level ladders should be built, and the width of the horizontal ladders should be more than 2 m. The size of the colonization hole is 60

cm (length) 60 cm (width) 40 cm (depth), mix the soil with well-rotted sawdust or humus under the pine forest or well-rotted manure, mix evenly and backfill into the hole.

Blueberry cultivation management:

For planting blueberries in pots, it is best to choose mud pots. The mud pot is breathable, cheap, and the disadvantage is that it 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.

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, and even the acidic soil of the flower and bird market** has a pH value of 6 at the lowest.

The above content reference:

1.Temperature. Rabbit eye blueberry requires an average annual temperature, and tall bush blueberries are cultivated in the range of average temperatures in the United States, Germany, and New Zealand, and rabbit eye blueberries are more suitable for cultivation in warm areas than tall bush blueberries.

Blueberry requirements for low temperature hours ( , generally the northern high bush blueberry requires 800 1200 hours of annual low temperature hours, the southern high bush blueberry requires 200 500 hours of annual low temperature hours, rabbit eye blueberry requires 400 600 hours of annual low temperature hours, and individual varieties only need 250 hours. If the low temperature hours cannot be satisfied, it is easy to prolong the germination period or the flower bud germination is less than the leaf bud, resulting in the imbalance of vegetative growth and reproductive growth. Blueberry cold tolerance is related to the development stage of varieties and flower buds.

Northern highbush blueberries are more resistant to cold than rabbit eye blueberries. The flower buds of the northern highbush blueberry cultivar were frozen and died at -29 and leaf buds at -34, and the flower buds at the base of the branches were more cold-resistant than those at the top. The late frost of the swelling flower bud-6 did not cause frost damage at low temperature, but when the scales had fallen off and small flowers were exposed in the flower room, it would die when it encountered low temperature of -4. When the florets in the flower room are not fully opened, frost damage will occur when encountering a low temperature of -2, and frost damage will occur when it is fully open and encountering 0. When the low temperature is -12 in winter, the new shoots of rabbit eye blueberry will die due to frost damage, and the minimum temperature in winter shall not be lower than -10 to avoid frost damage.

2.Moisture content. The growth period of blueberries in a year from April to October requires 700 to 1400 mm of precipitation, too little or too much requires intensive irrigation or drainage measures.

Among the several groups of blueberries, the rabbit-eyed blueberry was the most drought resistant, the semi-tall bush blueberry was stronger than the tall bush blueberry, and the dwarf bush blueberry was the weakest. The blueberry with high bush was the strongest waterlogging tolerant, followed by the semi-tall blueberry, and the weakest was the dwarf blueberry.

Suitable temperature for blueberry growth: Blueberries can tolerate 40 to 50 high temperatures in their surroundings during the growing season, and growth is stunted due to poor water absorption by the roots above this temperature range. Bush blueberries produce more rhizomes at 30 than at 18 and grow faster.

In blueberry producing areas, low summer temperatures are the main limiting factor for blueberry growth and development. When the soil temperature increased from 13 to 32, the growth of highbush blueberry increased proportionally.

Temperature has an effect on the light and action of blueberry leaves. The photosynthesis of bush blueberries varies with temperature to 13 to 29. 5c and increase. Lanfeng cultivar leaf CO2&

#40;Carbon dioxide &

#41;The absorption rate increases from 20 to 30 with increasing temperature.

The low temperature in early spring is not conducive to the growth of blueberries, and when the blueberry leaves are subjected to frost and cold in the Changbai Mountains, the leaves do not fall off, but turn into abnormal red, thus affecting photosynthesis.

After the leaves turn red, it takes about a month for them to turn green as the temperature increases.

Temperature also has an effect on flower bud formation and fruit development. The number of flower buds formed at the time of the bush blueberry is much greater than the number of flower buds formed under the conditions.

The fruit setting rate of blueberries was nearly 1 times higher than that of the cool temperature of 8 24 at 16 27. Moreover, when the temperature is high, the fruit develops quickly, the fruit is large, and the ripening period is 2 to 5 days earlier than the low temperature condition on average.

Therefore, controlling the temperature well is a key control factor for blueberry cultivation.

FYI.

<> blueberries enter the fruiting period, it is generally possible to apply low-concentration upshift potassium dihydrogen phosphate solution and other fertilizer shortage materials. Precautions: Do not apply chemical fertilizers with too high concentration, otherwise it may lead to fruit drop in noisy cherry trees; The frequency of fertilizer should not be too high, generally 1 time per month, because too frequent fertilizer is prone to fertilizer damage.

Summary. 1.Blueberries need a sour soil environment, and they generally grow better in a deep soil layer and loose texture.

2. Blueberry seedling selection is the basis for seedlings and fruits, and blueberry seedlings are recommended to be cultivated for more than 2-3 years, and robust seedlings with complete roots and 3-5 branches and leaves are selected for cultivation. 3. Blueberries prefer a warmer environment, and the planting time in China is often in March-April and September-November, and the relative survival rate will be higher. After planting in autumn, it is recommended to cover the pit seedling surface with sawdust or bark to regulate the low temperature and prevent water evaporation.

It is recommended to use organic fertilizer, peanut bran ten chaff brigade to make fertilizer, fill the bottom of the pot first, and then add some organic fertilizer to make the bottom fertilizer, add organic fertilizer to provide nutrients for the subsequent growth of blueberries, stir evenly and continue to fill the soil inside, to avoid direct contact between the roots of blueberry land town code and fertilizer, resulting in the situation of burning seedlings, fill to the appropriate height, put the blueberry plants in, and fill the surrounding soil.

Hello: Try to avoid fertilizing blueberry trees in high temperatures! After the summer enters, sufficient fertilizer to supplement, the surface of the potting soil is dry and water it in time, its fruit will quickly become a cover and mature early, and it will be picked after it is ripe, we will go to it to supplement it with some multi-element fertilizer, so that it can recover the nutrients consumed in the process of flowering and fruiting, and then we choose nitrogen-based fertilizer to supplement it in the hungry years, so as to promote its rapid growth of side buds, the longer the side buds, the more the new side buds gradually become older. Then we need to keep about 10 centimeters of branches, just top it, and then let it grow enough side buds.

In autumn, don't prune it, don't top it, let its branches slowly age, and in the second year, it will be able to bloom and bear more fruit. Thank you for the new trust, the above is my reply, I hope it can help you, I wish you a happy life

Potted blueberry fertilization is carried out in early spring before bud break and is applied in two installments. Also, apply once when the berries are ripe. The method of fertilization varies from variety to variety.

The low bush is sprinkled with the method of sowing, and the high bush and rabbit eye are applied by the furrow method. Also pay attention to the amount applied, once the excess, it is easy to cause damage to the tree.

First, the fertilization method.

The fertilization method of blueberries varies depending on the variety. After the bushes are established, they are usually connected into patches and should be sown by scattering. For tall bushes and rabbit's eye blueberries, a small ditch 10 to 15 cm deep should be dug and the fertilizer should be buried.

Second, the method of self-made fertilizer.

The fertilizer used to fertilize blueberries is generally made by yourself, and the method is very simple. Prepare an oil pot first, mash the rotten fruits into it, and then water it to ferment, and it will take about a week to make it. It is best to test it with pH paper before applying, and the pH value is around 5-6.

You can also choose a fertile leaf water-soluble fertilizer.

3. Fertilization time.

Soil fertilization is carried out before budding in early spring, preferably in two installments. In addition, applying it again when the berries are ripe will make the fruit more flavorful and more attractive.

Fourth, apply the dosage.

Pay attention to the amount of fertilizer application, once the excess is easy to damage the tree, and may even lead to the death of the whole tree. The specific dosage should be determined according to the fertility of the soil and the nutrients of the tree.

Fertilize potted blueberries, this 1 point should be kept in mind, otherwise there will be fertilizer damage, or even the whole plant will die.

Answer: We must avoid using fertilizers such as ammonium chloride and potassium chloride, and try to use potassium sulfate compound fertilizers. In addition, blueberries do not like nitrate nitrogen, and the use of nitrate nitrogen is easy to cause the death of blueberry trees, so the use of ammonium nitrate, potassium nitrate, calcium ammonium nitrate and other fertilizers should be avoided when planting blueberries.

Blueberries have the characteristics of too much fertilizer and too calcium, generally in the early stage of blueberry planting, you can use humus soil or add some rotten cow, sheep, rabbit manure, and then a small amount of top dressing is also needed in the planting process, but do not fatten. The general selection content is 1:1:

1 of nitrogen, phosphorus and potassium type Bika granule compound fertilizer or ammonium sulfate 1:2000 times solution is sufficient. Remember to stay away from calcium-containing things, for example, some flower lovers tend to place eggshells in flower pots, which is not conducive to the growth of blueberry plants.

Summary. Blueberry summer fertilization Hello, pro 1Top dressing is mainly fertilized by drip irrigation, which can be fertilized with watering in several periods such as germination, fruit expansion and fruit picking.

The fertilizer raw materials used in drip irrigation fertilizer must have high solubility and low impurity content. The products of the carbon replenishment series are on the line. When mixing fertilizers, pay attention to the matching of fertilizers to prevent precipitation, and the trace elements should be in chelated state.

2.Extra-root topdressing refers to spraying fertilizer on the tree body, specifically should pay attention to the two periods before defoliation and before germination, urea before defoliation, and zinc before germination. Nitrogen fertilizer and boron fertilizer were sprayed at the flowering stage, calcium was supplemented after fruit set, and phosphorus and potassium fertilizer were mainly sprayed at the fruit expansion stage.

Foliar fertilizer should be sprayed in the morning or afternoon on a cloudy or sunny day with a temperature of 18 to 25 years, with the leaves on the front and back.

Types of fertilizers used for blueberries in summer.

Types of fertilizers used for blueberries in summer Hello, pro "Compared with organic fertilizers, blueberries are more suitable for organic fertilizers with complete nutrients, rich microorganisms and low salinity. Such as: fermented chicken manure, pig manure, cow manure, all kinds of cake fertilizer, bone meal and other organic fertilizers. ”

Shouldn't blueberries be water-soluble fertilizers in summer?

Blueberries are more suitable for organic fertilizers that are nutritionally complete, rich in microorganisms, and low in salt.

Blueberries are fertilized during the summer nutrition growth period.

The use of water-soluble fertilizer on blueberries Strictly speaking, the fertilization of blueberry fruit trees depends on the blueberry tree variety, blueberries have high bush blueberries, rabbit eye blueberries and dwarf blueberries, among which high bush and rabbit eye varieties can be applied the same balanced water-soluble fertilizer, dwarf bush blueberries need to apply high nitrogen and potassium water-soluble fertilizer, as follows: (1) high bush, rabbit eye, the flower fruit general water-soluble fertilizer formula, the amount per mu is 5 kg, mixed with water 800-1000 kg, fully dissolved after the root is evenly applied. It is usually done every 10-15 days.

High bush, rabbit eye topdressing water-soluble fertilizer (2) dwarf bush, dwarf bush blueberry fertilization in the berry ripening period topdressing high nitrogen and potassium water-soluble fertilizer, the same is an acre of land 5 kg with water 1000kg fully dissolved and stirred, the root flushing.

Blueberry summer slightly nutritious growth period with fertilizer Hello, dear. Compared with chemical fertilizers, blueberries are more suitable for organic fertilizers with complete nutrients, rich microorganisms and low salinity, such as: fermented chicken manure, pig manure, cow manure, various cake fertilizers, bone meal and other organic fertilizers, which are milder and have a longer fertilizer effect.
