Why do the processing

Novice gardeners often do not attach importance to the prevention of polycarbonate products used in their area. But, for example, in greenhouses from such material spores and parasites winter. They settle in the soil, frame details and greenhouse inventory. For this reason, it is very important to carry out all agricultural activities in the form of processing greenhouses in the fall from pests and diseases.

Of course, not all inhabitants harm plants. Soil is considered a living organism, where many bacteria live. They are constantly engaged in the processing of organics into chemical compounds necessary for the normal growth and development of crops. Various insects live in the ground, but not all of them are dangerous for vegetables and berries.

The greenhouse microclimate favorably affects the development of pathogenic flora.

Important!

High humidity and temperature conditions contribute to the active growth of plants, as well as the spread of pathogens. In the spring, after sowing or planting, they affect vegetables and other crops.

The fight against them must begin immediately after harvest. The event will be successful only if you know how to handle the polycarbonate greenhouse in the fall. This is very important if it is not planned to replace the soil. Sometimes such work is carried out in the springbut it’s better to do it in the fall. The measures taken will improve the preservation of future fruits and reduce the risk of crop damage by diseases and pests.

Main steps

If disinfection of the polycarbonate greenhouse is neglected, then harmful bacteria will again infect the planted crops in the new season. It is known that many pathogenic pathogens do not lose their activity for a long time. This applies to phytophthora spores that destroy tomatoes. Autumn processing of a polycarbonate greenhouse can effectively eliminate whiteflies, aphids, spider mites, nematodes and other parasites.

It is recommended that all work be performed in the following order:

collect and remove all plant residues from the greenhouse;
wash, clean the walls and roof of the greenhouse;
perform processing and soil preparation;
disinfect;
if necessary, make minor repairs to the structure.

Advice!

The best time for disinfection work when the air temperature is at the level of 10-15^about with a plus. From the greenhouse, it is necessary to take out all the pegs and garter material, as well as tools, racks. If polycarbonate is removed in the structure, then it is better to remove the coating.

Soil disinfection

The soil is freed from plant debris. Roots, stems and fallen seeds should not remain on its surface. If the plants were treated with drugs due to illness, then they should be completely destroyed. Healthy can be used in a compost pit.In the future, such compost is not recommended for growing the same species.

Inventory and other items must be taken out and sanitized. It is recommended to remove the top layer of greenhouse soil by 7–9 cm. After this, a new healthy composition should be introduced. Now you can add organic fertilizers and start digging the entire soil, capturing the lower part. When such work is carried out in the spring, the use of fresh organics is omitted.

If there was no massive plant disease and pest attacks in the current season, then the soil can be left behind. However, it must be disinfected after being dug up. For this usually one of the means in the form of a solution is used:

copper sulfate;
lime and chlorine;
3% iron sulfate.

Greenhouse soil is also often treated with boiling water, which is very important for the spring season. But after such procedures, earthworms will be affected, which improve the composition of the earth. They enrich it with humus and improve the structure. Chemicals are best used only in the fall.

Scaffold and coating

The polycarbonate coating should be carefully inspected so that it does not have rust and various damage. If so, they must be removed or repainted. Frame elements are recommended to be washed with a warm soapy solution.

Every spring or autumn, you must remember to wash the greenhouse inside and out. After processing, the polycarbonate must be wiped with a damp cloth. It is undesirable that the composition hit the ground. Detergent for disinfection is usually selected non-abrasive. In order not to damage the polycarbonate, you can use soft sponges instead of rags.

Methods and Tools

Processing a greenhouse in the spring is different from autumn disinfection. This is due to the use of certain means. It is believed that in the spring sometimes only biological compounds can be used. For fall, the following methods are suitable:

fumigation with a sulfur saber or cuttings sulfur;
vitriol irrigation;
spraying with bleach.

However, the sulfur product is not suitable for processing if the greenhouse frame is made of galvanized steel. For wood or painted surfaces, it is suitable. With such a disinfection, protective objects must be used, since sulfur emits toxic substances.

Advice!

For disinfection of 10 m³ 600 g of sulfur will be needed. Ready checkers must be placed throughout the territory, then set on fire and immediately exit. With this treatment, the door should be tightly closed so that there is a maximum concentration of the substance in the greenhouse.

According to this principle, processing by cuttings of sulfur is done, only the funds are taken at the rate of 1 kg per 10 m³laying everything on metal baking sheets. The main substance is ground, then mixed with charcoal in equal proportions, and then set on fire. After such work, the greenhouse should be kept closed for 5-7 days. Then it is aired for about 2 weeks.

For many gardeners, the topic of how to process a greenhouse in the fall is relevant, since such measures will affect the yield in the next season. For example, bleach is suitable for spring and autumn season.

To do this, take:

1 liter of water;
400 g of bleach.

The diluted composition is placed in a container with a spray and insist 4 hours. After that, it can be used to spray the greenhouse and soil. The building is closed for 2 days and after that it is well ventilated. With this composition, you can disinfect greenhouse equipment.

Useful!

Processing a greenhouse with copper sulfate in the fall or spring is considered a good tool. To prepare it, take from 10-150 g of substance per 10 l of water, depending on the degree of crop damage in the current season.The dissolved composition is poured into a container and then the whole structure is sprayed with it.

Winter preparations

If it is not planned to grow crops in the greenhouse in the winter season, then it is best to leave it open. Freezing the soil does not take time and money. To do this, fix the doors and windows in the ajar position. The method of freezing the earth allows you to effectively get rid of most pests wintering in greenhouse soil.

This method will help to equalize the temperature inside the building. After this, condensation and ice will not form on the walls of the greenhouse. The collected snow will become easier to remove, and most often it leaves under its own weight.

It is advisable to throw snow into the greenhouse at the end of winter, which will moisten the soil well. From this, all soil microorganisms living in the structure will wake up earlier and take care together with moisture to increase productivity.
