For the growth of cucumbers and getting a good harvest requires a complex feeding. Its composition includes minerals of various ratios. In the greenhouse for cucumbers complex fertilizers are applied sequentially. At each stage of plant development requires a certain set of mineral substances.

Especially useful dressings before flowering and during the fruiting of cucumbers. Before planting, attention is paid to soil preparation. At observance of the established proportions cucumbers will receive feed for active growth, emergence of inflorescences and tasty fruits.

Signs of fertilizer shortages

With a lack of nutrients, cucumbers develop more slowly, the leaves turn yellow and the inflorescences fall on them. By the nature of the negative changes, it is possible to determine which substances the complex feeding should include.

Nitrogen deficiency is expressed by certain symptoms:

  • yellow leaves on leaf streaks;
  • growth of main stems and shoots stops;
  • fruits become lighter;
  • cucumbers thicken at the stem.

Potassium deficiency also has a number of manifestations:

  • increased foliage growth;
  • on the lower leaves there is a yellow border;
  • cucumbers become pear-shaped.

The following signs are characteristic of the lack of phosphorus:

  • side shoots grow slower;
  • new leaves are darker and smaller in size.

Calcium deficiency can be determined by a number of symptoms:

  • flowers fall;
  • the taste and quality of cucumbers deteriorates;
  • leaves roll up.
Important! Excess fertilizer also does not benefit cucumbers.

When saturated with nitrogen, the flowering of cucumbers slows down, a thick stalk and dark green leaves grow. Excess phosphorus leads to yellowing of cucumber leaves. Excess potassium inhibits nitrogen absorption, thereby slowing plant growth. An excessive amount of calcium provokes the appearance of spots on the leaves of cucumbers.

Useful trace elements for cucumbers

For the full development of cucumbers need to provide high-quality feeding. It is best to make complex fertilizers that contain various trace elements.

The most effective for cucumbers nitrogen, potassium and calcium. Comprehensive dressing will help in cases where it is difficult to determine by what external signs what substances are not enough for cucumbers.

Nitrogen

The main trace element that ensures the development of cucumbers is nitrogen. On its basis, a sapling is formed, so nitrogen is first introduced into the greenhouse.

Nitrogen is a component of proteins that are involved in the formation of the nucleus and cytoplasm of cells. Also, this element forms organic compounds, vital for plants.

Important! When nitrogen is introduced into the soil, it is necessary to take into account that this substance is contained in manure, peat and compost.

To saturate the soil with nitrogen requires a complex fertilizer, which additionally contains molybdenum and iron. Thus, nitrogen is transformed into a harmless form and does not accumulate in cucumbers.

Potassium

Potassium is responsible for the taste and appearance of cucumbers. With a deficiency of this element, the fetus becomes irregular in shape, since the substance spreads unevenly through the tissues.

Plants send potassium from the soil to the fruit, so its lack immediately reflects on the state of the foliage.

Complex fertilizer for cucumbers includes potassium sulfate, which increases crop yield. Another of his actions is to increase immunity in plants. The substance is completely soluble in water and applied to root feeding.

Calcium

Calcium forms walls and membranes of cells. With its deficiency, the ovary dies, and the fruits lose their taste.

Calcium is present in wood ash, therefore fertilizer based on it is considered one of the most effective for cucumbers.

The ash contains calcium carbonate, which affects the metabolic processes of the plant. Due to it, the speed of movement of substances increases, biochemical processes are normalized.

Calcium sulfate is used for complex fertilizers. It is also part of the superphosphate - a common mineral fertilizer.

Phosphorus

Cucumbers require a small amount of phosphorus, however, it must be supplied continuously. The element is necessary for the growth of cucumbers, the formation of the root system, the setting and ripening of fruits.

Phosphorus is especially important with the appearance of inflorescences. Therefore, it is added to the mineral fertilizer after planting cucumbers in the greenhouse.

Sulfur

Sulfur is often used for complex fertilizers, as it helps cucumbers absorb nitrogen. Sulfur is completely absorbed by plants, does not accumulate in the soil and does not oxidize it.

Types of complex fertilizers

Complex fertilizer can be obtained independently by mixing the components in the required proportions. All components can be purchased at a gardening shop.

Various types of mineral fertilizers are supplied as a complex of substances, ready for use. For cucumbers, it is recommended to use a nitrogen-based feed.

Diammofoska

Diammofoska has the form of granules, which are chemically neutral. Substances dissolve in water and are well absorbed by cucumbers.

This complex fertilizer is applied to the soil to a depth of 10 cm. The components are scattered on the surface of the soil between the cucumbers. Diammofosku usually used after planting before flowering.

Tip! On 1 square. m requires up to 15 g of fertilizer.

Diammofoska begins the action immediately after entering the soil. Due to nitrogen, the growth of cucumbers is activated, after which the phosphates help them to get stronger. Then potassium promotes the absorption of phosphorus and increases the yield of cucumbers.

Ammofoska

Ammophoska is a complex type fertilizer containing nitrogen, phosphorus, potassium, sulfur. This is a universal substance that can be made regardless of the season, except for autumn.

Important! If you use nitrogen-containing substances in the fall, then this will trigger the active growth of cucumber foliage.

Ammofoska suitable for all types of soil. This fertilizer is especially necessary for regions with arid climate, where the need for nitrogen in cucumbers is particularly high.

When using ammofoski apply protective equipment for the eyes, hands and respiratory system. In case of contact with the skin, thoroughly wash the area with water and soap.

Nitrofoska

Nitrophoska is an improved form of ammofoski. The content of nitrogen, phosphorus and potassium, there are various options nitrophoska.

The substance is available in granular form. For feeding cucumbers apply sulfate nitrophoska. Its composition also contains sulfur. Due to this, it turns out not only high-quality feeding, but also a substance that can repel pests.

If nitrophosphate granules are used, they are introduced into the soil to a depth of 8 cm. To obtain a solution for irrigation, 40 g of a substance per 10 liters of water are required. For each seedling you need up to 0.5 liters of this solution.

Stages feeding cucumbers

Feeding cucumbers includes several stages. Between each stage should take up to 10 days. Additionally, you need to prepare a soil for cucumbers in the autumn and spring.

Integrated recharge required cucumbers in the following steps:

  • after planting seedlings on a permanent place;
  • before flowering;
  • during the fruiting period.

If necessary, additional feeding can be carried out if the plant is experiencing nutrient deficiencies.

Autumn tillage

Cucumbers are not recommended to be grown several times in one place. In the greenhouse, this rule is much more difficult to follow. If you need to choose the location of the greenhouse, then preference is given to flat areas without obscuration.

Important! After the harvest of cucumbers, which usually occurs in August-September, the ground needs to be dug up.

Be sure to remove a layer of earth up to 10 cm thick, where harmful bacteria and disease spores accumulate. The greenhouse is disinfected with a solution of blue vitriol or other substances.

In the autumn in the greenhouse you can plant mustard, which grows in about a month. This plant will continue to be a good fertilizer for the soil. Additionally, mustard serves as a protection against pests.

Soil for greenhouses need to form in the fall. This requires equal proportions of the following components:

  • peat;
  • humus;
  • turf ground or black earth.

Complex fertilizer is added to the received soil per 1 square meter:

  • ash - 200 g;
  • superphosphate - 1 tbsp.

After making these components, the soil is dug up. The soil must have high fertility, pass air and absorb moisture.

Spring tillage

Planting cucumbers can be done early - from early to mid-May. This option is suitable for regions with a warm climate. Late landing starts from the end of May and lasts until the beginning of June.

Before planting cucumbers in the greenhouse you need to prepare the soil and make a set of fertilizers. Works are carried out a week before planting cucumbers.

Pre-soil carefully digs. Complex fertilizer is added to 1 square meter of soil:

  • ammonium nitrate - 10 g;
  • superphosphate -30 g;
  • potassium sulphate - 10 g

A solution of potassium permanganate (2 g per 10 liters of water) is used to disinfect the soil. This solution is watered the ground, received a complex fertilizer. Then the surface of the beds covered with film and left for a week. After that, they start planting cucumbers.

Tip! For new greenhouses you need to prepare a mixture of turf soil and manure.

First, manure is laid, which is dug up to a depth of 20 cm. Fresh manure is added to the mixture with the addition of sawdust. This forms an effective drainage layer.

The top layer of soil for cucumbers is compost up to 25 cm thick. After this preparation, the soil is enriched with complex fertilizer.

Fertilizers for seedlings

First, seedlings of cucumbers are grown, which are then transferred to a greenhouse. Pre-seeds are disinfected, then dried and planted in boxes. For seedlings preparing the soil consisting of peat, garden soil and humus.

Additionally, the soil is treated with potassium permanganate solution to eliminate harmful microorganisms. Then the soil is watered with warm water and dried.

In the resulting soil planted cucumber seeds. The first shoots appear after 3-5 days. Several cucumbers are planted in each container, then the strongest shoots are left.

Tip! Planting in the greenhouse is performed after the appearance of the second or third leaf of the seedlings.

The transfer of plants is carried out in warm weather. It is best to choose a cloudy day, morning or evening. Pre-ground in boxes and greenhouse need to be watered.

Ammofosc is placed in the finished well. Its composition does not contain chlorine and sodium, which have an aggressive effect.

Important! On 1 square. m of soil is enough to 30 g of ammofoski.

Then the cucumbers are carefully planted, covered with earth and poured over with warm water.

Top dressing at flowering

In the period of growth of cucumbers to make complex fertilizer is not necessary before flowering. If seedlings grow well, then use additional substances is not necessary.

Attention! Before flowering for cucumbers, fertilizer containing nitrogen is selected.

When cucumbers develop slowly, you definitely need to feed them. The first feeding is done 2 weeks after transplantation.

The composition of the first feeding includes the following fertilizers:

  • urea - 1 tbsp. l .;
  • superphosphate - 60 g;
  • water - 10 l.

Another option complex fertilizer contains the following components:

  • ammonium nitrate - 10 g;
  • superphosphate - 10 g;
  • potassium salt - 10 g;
  • water - 10 l.

On the surface of the beds need to scatter diammofosku or ammofosku, after which - loosen the soil. So, cucumbers will receive the nitrogen necessary for full development.

Additionally, organic fertilizers are used: slurry, chicken or cow manure. Superphosphate can be added to the solution of mullein.

The second feeding is made before the flowering of cucumbers. This is a mandatory stage of plant care, even if the first feeding was not performed.

The composition of the second feed includes:

  • potassium nitrate - 20 g;
  • ammonium nitrate - 30 g;
  • superphosphate - 40 g;
  • water - 10 l.
Tip! For cucumbers useful mixture consisting of ash and superphosphate. Fertilizer must be applied to the soil by loosening.

Watering complex fertilizer is performed under the root of cucumbers. Per 1 sq. M of land requires up to 3 liters of mortar. Organic fertilizer (infusion of green grass) is used for complete feeding.

Fertilizing during fruiting

During the period of fruiting cucumbers require an influx of nutrients. Comprehensive fertilizer, including potassium and magnesium, will help provide it. The nitrogen concentration for such feeding is minimal.

Nitrophoska is introduced after the appearance of the first fruits. Fertilizer is obtained by dissolving 1 tbsp. substances in 10 liters of water.

If nitrogen acts after fertilization, the phosphorus compounds are activated after a few weeks. Potassium affects the taste of cucumbers, as it helps the production of vegetable sugar.

It is possible to provide cucumbers with potassium by adding potassium nitrate. 10 liters of water requires up to 30 g of this substance. Potassium make-up is produced with the help of fertilizer obtained by mixing a glass of ash and a bucket of water.

Important! The following feeding is carried out every week.

During the period of fruit formation, additional mineral supplements are often required. Its purpose is to prolong the fruiting and increase the number of ovaries. A useful effect for cucumbers has a solution of food water. It is diluted in an amount of up to 30 g per bucket of water.

Conclusion

Complex fertilizers for cucumbers include nitrogen, potassium, phosphorus, calcium. Cucumbers require additional feeding throughout the entire life cycle. Fertilizers are allowed at the stage of soil preparation. In the future, cucumbers need to receive nutrients during flowering and fruiting. The frequency of dressings depends on the state of the plants.

To obtain a fertilizer with a complex effect, it is possible by mixing the necessary components. A simpler way is to purchase ready-made substances. They contain useful ingredients in the required proportions and are fully ready for use. When working with complex fertilizers, personal protective equipment is required.
