Covering material for greenhouses and hothouses: the optimum microclimate for crops

Covering material for greenhouses and greenhouses - a modern way to protect plants from pests, the active sun and inclement weather. He not only has the properties of obstruction, but also helps to create the optimum climate to produce a good harvest. On the market there are several types of covering materials, each of which has its own advantages and features.

Covering materials for hothouses and greenhouses: the characteristics, the types and characteristics of the

Farmers and gardeners-fans know that planting indoors allows you to grow crops that are not always adapted to the local climate. Greenhouses of different designs are a common sight in the fields and suburban areas. However, their effectiveness could be much higher if we use modern covering material - agrovoloknom.

This non-woven synthetic material has such features:

• excellent pass moisture but has substantially zero hygroscopic;
• eco-friendly material, harmless to plants and humans;
• It protects plants from UV radiation;
• It protects against excessive precipitation and extreme weather conditions such as hail or hurricane;
• It provides protection from pests and birds;
• It retains heat inside the structure at low frost on the ground and levels the day and night temperature differences;
• without obstacles breathable;
• It does not contribute to the formation of condensation;
• easy to use and storage;
• It has strength and abrasion resistance;
• It does not rot and moldy during the operation;
• life - for several years.

Note! The non-woven covering material environmentally friendly. It consists of polypropylene fibers that are bonded together under high temperature.

The combination of these properties makes it possible to increase crop yields by 20% due to choose the right covering materials. Its price is comparable to the cost of a polyethylene film, that for many farmers will be a pleasant surprise. At the same time, if we take into account the excellent performance and long service life of the non-woven material, the acquisition of its more profitable. For example, under the cover material tomatoes can grow to their full maturity in the open field, while the film can not guarantee a successful outcome.

Types of coatings for greenhouses agrovoloknom

In specialty stores and on the Internet you can find a wide range of covering material for greenhouses and greenhouses. Its price fluctuates different limits and depends mainly on the producer, characteristics of application, method of packing density (or threaded rolls sheets).

For all types of covering materials of any manufacturer is characterized by the color classification:

• white covering material has a different density and is used for covering plants, forming hotbeds and greenhouses;
• Black - it's covering material of weeds, it is always very busy and fit only on the ground for mulching.

Important!Black and white covering materials are not interchangeable. Use each of them for their intended purpose: white - top, black - bottom.

The density of a covering fabric - it should be defined collation. To the consumer it easier to navigate in the modifications, manufacturers specify the density level in the product name. For example, Agrotex 30 has a density of 30 g / m² and Agrotex 60 - respectively 60 g / m². The higher the number next to the name, the higher the density of the material.

density value directly affects the use of agrovoloknom and its cost. At the same dimensions of leaf price covering material for greenhouses or greenhouses will always be higher for products that have density level greater than the cost of similar thin material, such as for shelters frameless cultures.

The most popular representatives of non-woven agrovoloknom in the domestic market are:

1. "Agrospan": Russian manufacturer, produced a 7-density versions and in two colors (black, white), UV-stabilizer.
2. "Agrotex": Russian manufacturer, performed a 5-density versions, there is an additional 5 colors other than the traditional black and white variants, UV stabilizer.
3. "Lutrasil": a manufacturer of Germany, produced a 5-density embodiments, a two-color (black, white), company name can be used as a common name for all kinds of name Agrotextile. Very broad canvas from all kinds of material - up to 16.9 m.
4. "Agril": producer, France, has four variants of density, UV stabilizer, 2 colors - black and white.

Let us consider that represents each of said materials, and receive their practical application for the cultivation of horticultural crops.

How to choose a covering material for greenhouses or greenhouses

As shown by the above characteristics of the covering materials, they have many common parameters. In deciding how best to choose a covering material should be guided not by the name and the manufacturer of fabric and its intended use. It is also worth to take into account the climatic conditions, the duration of the warm period, the frequency of sudden frost, wind, etc.

When using any type agrovoloknom first of all we need to pay attention to its density and color. For frame structures used white cloth. Some manufacturers have modifications in color and increased strength - reinforcement. These preferences are highly individual.

Optimal density covering material is defined by parameters:

• time of planting in the soil;
• height growth horticultural crops;
• climatic conditions;
• height and type of structure being built shelters.

What better covering material for greenhouses or greenhouses? In the first place, the density of which is greater than 30 g / m² and having a UV-stabilizer. For structures greenhouses always choose the most dense agrovoloknom - 50 g / m² and above. For greenhouses low arc designs will be enough fabric marked density 30-40.

UV stabilizer has an effect on the durability and safety of a covering material of its initial properties throughout the several seasons. Visually, the presence of a stabilizer in agrovoloknom can not be determined, therefore it is necessary to acquire products packed in the production, which has the appropriate marking of the manufacturer and protective signs.

Note!If the purchase agrovoloknom rolls, then at the shelter greenhouses or greenhouse you can save. The remaining unused portion of the roll is stored indefinitely.

How to use covering materials for hothouses and greenhouses

The nonwoven covering material in very low maintenance and easy to care application. However, when using it for the first time should know some important aspects that will help agrovoloknom save properties, to avoid financial loss and frustration in growing garden cultures. For example, it is necessary to take into account which side to put on a greenhouse covering material, whether it is possible to clean it, what to do if the web is not enough to fully cover the design, etc.

Let us examine the main aspects of the use of a covering cloth.

Methods of laying a covering material for greenhouses

Fabrics agrovoloknom never tailor prematurely. Originally set for greenhouse frame or arch, with covering materials begin to work only after the implementation of this phase. The cloth is placed on top of the arcs, creating allowances on all sides by at least 20 cm, and cut off only after all necessary measurements. The length of the blade is not calculated from the first edge of the arc to the latest, and taking into account the closed greenhouse ends. Work with the non-woven fabric similar to the process of the covering film arcs.

Covering material produced with different widths. However, it may happen that can not be fully covered all greenhouse agrovoloknom a cut of one. In this case the webs are interconnected overlapping joint space Melt adhesive glued or sewn thread. You can use a sewing machine.

Before finally fix the fabric on the edges, it is necessary to find out which side of the cover. Covering material for greenhouses has different properties of the upper and lower layers. It must be considered. Simply, when the two-color material: the manufacturer indicates on the package, how to distinguish between upper and lower sides. If the canvas is white, then it is determined visually and by touch: the smooth side is laid down, "rough" with holes - up.

You can check on the new cutting off of the packaging in which direction the web watertight. When buying a coil coating needs to know that the material wound up the top layer to the outside. When completely homogeneous (both sides), the material does not matter which side of his stack.

What and how to fix a covering material

When agrovoloknom successfully laid on the arc, it remains securely fixed. Covering material can be fixed on the arcs as a greenhouse specialized materials and the materials at hand. The garden tools shop sells special plastic clips or clamps to fix: they come for the film, and for agrovoloknom. Knowing the diameter of the arcs, you can pick the right size.

If you have an old hose into the economy, it is cut into lengths, cut them lengthwise and put a clamp on an arc with a cover material. However, if the hose is insufficient rigidity, when strong gusts of wind coverage will fly. Therefore, the hose should be replaced by a plastic tube which is cut along the length of the segment corresponding to approximately ¼ diameter. Sharp edges of the pipe sections is recommended to treat sandpaper.

Some gardeners use to fix agrovoloknom normal office binders large. Such mounting requires additional pads, for example, a piece of fabric to fabric not break over time.

The bottom of the covering material on greenhouse fixed pegs or special presses bricks, wooden beam and other weighting agents.

Note! When installing fixtures worth considering that for plants that require pollination, it shall be possible to open the greenhouse when they bloom.

The non-woven covering material allows you to sew a real cover for the greenhouse. Knowing the step of the installation of poles, cross sewn on canvas "pockets" in which are then inserted into the arc. In this case, the installation of a greenhouse design provides a change in the order of installation.

How to clean and store where the covering material

The duration of operation agrovoloknom always within the specified term of the manufacturer. Material can last much longer if you treat it with care. After removal from the greenhouse must be dried web is folded and put in storage in a dry, dark place. The most dense frost covering materials can remain on the site throughout the year.

If a covering product in the application period is dirty, it is recommended to clean sponge or soft brush. If particularly dirty cloth can be washed with soap or detergent.

Any amateur gardener or farmer wants to receive high yields every year, while spending a minimum of effort to care for the plants. The use of non-woven covering material - this is the right step towards achieving this goal.
