Why does the ovary of cucumbers dry in the greenhouse?

Many gardeners who practice growing cucumbers sooner or later face this problem when the ovaries of cucumbers dry in the greenhouse and the fruit not formed. Accordingly, the question arises of how to deal with this and how not to lose the crop. To take action, you need to find out the reason that provoked such a process. There are several possible reasons.

The ovary of cucumbers in the greenhouse dries

Possible causes

The main factors that lead ovaries can become yellowing and drying;

• violation of the technology for growing greenhouse cucumbers;
• soil depletion, lack of minerals;
• violation of the water regime (drying out , waterlogging);
• inappropriate temperature conditions;
• poor pollination;
• the harmful effects of diseases and pests.

These are the main reasons that should be analyzed in detail in order to understand how to influence the situation. At the heart of any violations in the growth of cucumbers is a violation of agricultural technology and the main recommendations for growing this garden crop. We will analyze in more detail which particular causes lead to the fact that the inflorescences of cucumbers dry up.

Non-compliance with the temperature regime

Cucumber is a crop that is very sensitive to temperature fluctuations. Badly affects the vegetation of the plant as hypothermia and overheating. For cucumbers, maintaining an adequate temperature is important for growth and fruiting. With a sharp change in temperature, the plant falls into a stressful situation and all the forces go to maintain the general condition. Accordingly, there is not enough strength to form and support the development of a full-fledged ovary.

To stabilize the temperature in the event of significant drops, an additional shelter is recommended. Use agrofilm or agrofibre. In the opposite situation, in order to lower the temperature, a greenhouse is ventilated, which can lower the degree, also partially remove the shelter during the heatwave, but do not allow direct sunlight to reach the plants, covering it with non-woven material.

Lack of trace elements in the soil

Often in greenhouses the soil has been used for many years without replacement, compost and mineral fertilizers. Or the application of mineral fertilizers in insufficient quantities. The soil becomes depleted, poor in trace elements. Lack of nutrients will not allow cucumbers to grow in full force and at the time of fruit formation, the ovaries of cucumbers in the greenhouse dry.

An important role for the growth of the fruiting organs and the formation of the ovary is played by a sufficient amount of boron.To stimulate fruiting, you can perform additional processing with this element.

The logical way out in this situation is to apply fertilizers according to the norms and instructions. Bioactive agents have a good effect in this situation. As well as phytohormones, which will give a quick result and give time to activate microelements introduced into the soil.

And to prevent such an error in the next season, the soil is prepared in greenhouses before planting seedlings. Dig and fertilize 3 times. It can be organic together with mineral, or complex mineral fertilizers.

Incorrect planting

A common reason for yellowing the ovaries is incorrect planting of bushes. Unsaved spacing between rows and thickened crops leads to poor ventilation, lack of sufficient space for the full development of the root and general vegetative system, and as a result of yellowing of the ovaries at the beginning of fruiting with a gradual deterioration in the general condition of cucumbers. When planting, it is worth observing the schemes and requirements, especially for greenhouses. It is important to remember that no more than three bushes are permissible per square meter, with a row width of at least 50 cm.

To improve the situation with a thickened planting and stopping the formation of the ovary, pruning the extra stems and leaves is carried out, if necessary, remove weak bushes to allow other stronger bushes to develop.

Insufficient or excessive watering

Cucumbers as a crop of tropical origin are very sensitive to disturbance of the water regime. Requires regular watering. In this case, warm, settled water is used. Cold water or drying out the soil provokes the drying of the ovaries of the cucumbers in the greenhouse, and the fruits do not grow in the correct form.

The regulated watering regime is important both for the general condition and growth of cucumbers so directly for the formation of a quality crop.

Insufficient pollination

Most often in modern gardening, partenocarpic (self-pollinating) varieties of cucumbers are grown in greenhouses, in which case insufficient pollination is excluded from the possible cause of yellowing of the ovary. If the cultivated varieties are bee pollinated then this is the case. Lack of a sufficient number of pollinator insects or a completely closed greenhouse will cause flowers to fall. And the reduction of inflorescences that form the fruit.

A good solution to this situation is to treat the plants with means that stimulate fruit set (for example, the drug Bud). And in the new season, to avoid unnecessary trouble, you should pay attention to greenhouse self-pollinated varieties.

Defeat of fungal diseases

Often infection with fungal diseases occurs in parallel with the violation of agricultural technology.

And in the case of poor quality agricultural technology the situation can be easily corrected by taking proper care. Then, with the addition of fungal diseases, the situation becomes complicated, and without an appropriate and timely treatment it will not be possible to save the harvest.

The main fungal diseases:

• fusarium;
• powdery mildew;
• parenosporosis.

When infected with fungal diseases, not only inflorescences often suffer, but also other components of the stems, leaves, cucumbers grow poorly and can die. Recognizing a fungal disease is not difficult. Each of them has its own characteristics. If infected cultures are detected, the best solution is to remove diseased specimens from the greenhouse and treat the soil and plants with fungicides. The soil should be shed with Trichophyte solutions, spray the bushes with a suitable fungicide, depending on the type of disease. The next season should begin with a thorough preparation of the soil. Mandatory is the cleaning of plant debris and disinfection of the soil.

Pest damage

Causes yellowing and drying of the ovary and the presence of parasitic pests on plants. Aphids, whiteflies, mealy worms, spider mites are pests that can cause irreparable harm.Parasitizing on crops deplete them, which stops their growth and fruiting process. Pest control is not as difficult as with fungal diseases. In order for the pests to cause minimal harm, the bushes are processed immediately after detection.

The treatment is carried out with insecticides (aphids, whiteflies) or acaricides ( mite worm, powdery worm) in the afternoon, in accordance with the instructions.After extermination of the pests, it is important to carry out preventive treatments to prevent re-infection.

Conclusions

The main reasons drying the ovary in the greenhouse are violations of the cultivation technique, and such violations drag along a number of other consequences. Plants become weak, poorly developed, affected by diseases and pests. And as a result, the time spent and the lack of the expected harvest. It is important that preventing negative experience is not difficult, compliance with agricultural technology and preventive measures will give a good result.
