Shading net for greenhouses: artificial imitation of shade for plants (58 photos)


Artificial fabrics are in demand in agriculture, they are actively purchased for suburban areas and private territories. Durable and at the same time light products perfectly protect plants from wind, insect pests, sunlight and negative external factors. The shading grid for greenhouses is mainly produced from synthetic yarns. Increasingly, polyethylene fiber is used for the manufacture of materials, which is characterized by environmental friendliness, resistance to various natural phenomena, wear resistance and other advantages. During production, foils may be added to the raw materials to improve the performance characteristics of the finished product.

Why do shading fabrics push out the film market?

Modern material is created with cells of different lengths and widths. Small cells let in less sunlight. Depending on the type of product, they are able to delay from 40% to 85% of the light. The most dense canvases best obscure the space.

The greenhouse netting grid confidently replaces wear-resistant polycarbonate, polyethylene and polyvinyl chloride films from the Russian market, which almost do not protect plants from ultraviolet radiation. After all, they miss up to 90% of the sun's rays. As a result, shrubs, trees, seedlings are prone to overheating during the daytime. At night, the ambient air temperature drops, which can cause slower plant growth. Due to temperature changes, seedlings are prone to disease. Because of the heat, they quickly evaporate moisture, which is necessary for the normal ripening of fruits.

Shading nets for greenhouses perfectly protect from the sun, so it is possible to create a favorable microclimate for the development of saplings, fruit trees and shrubs. They effectively protect against heat and any other atmospheric effects.

Important performance advantages and features of polyethylene mesh

The material is characterized by such important advantages:

  • Artificial fabrics are able to trap not only the sun's rays, but also moisture. As a rule, products are mounted on the outside of artificial structures or stretched on a frame made of metal wire or wood.
  • Cloths are able to evenly distribute the sun's rays and dissipate heat over space. As a result, excellent conditions are created for the development of plants, because they will not overheat. Saplings, shrubs or trees will evaporate less moisture, so water consumption is reduced for watering in hot weather.
  • The greenhouse shading net is UV resistant and retains its original performance under its influence. For example, polycarbonate gradually collapses under the influence of UV rays: it loses transparency, its mechanical strength decreases.
  • The material makes it possible to create a uniform illumination inside the building or around a certain space. As a result, the owners of a private plot harvest at the same time from most plants.
  • No harmful fungus forms on the surface of the products. At the same time, the material prevents the reproduction of various microorganisms.

As practice shows, pritenyayuschaya grid is ideal for greenhouses, where grow a variety of vegetable crops. According to numerous studies, the material allows to increase the yield. After all, the leaves absorb the scattered light better, so photosynthesis is enhanced. For example, the yield of tomatoes increases by 5-10% in buildings that are covered with artificial fabrics.

Why is polyethylene used for production?

Polyethylene from which products are created, is characterized by high strength. At the same time artificial fabric differs in ease and simplicity of installation. It is incredibly resistant to stretching in all directions, so it does not tear during installation and use. Interestingly, the coating material created by technology, which is actively used in the production of body armor.

Shading nets for greenhouses, even at elevated loads, will serve the owner for 7-10 years. They are used both inside buildings and in open areas. They stand out for low weight, so they are easy to stack, and if necessary they are easy to remove. As a result, it is possible to effectively control the illumination inside the space in both sunny and bad weather.

Polyethylene retains its initial operational properties at a temperature that varies from -65 ° C to + 115 ° C. The material withstands constant heating and cooling. During storage and transportation of cloth does not break.

The greenhouse grid is also produced from other materials. For example, for the manufacture of products used fabric:

  • Products stand out low cost, well protect plants from the sun. Because of their operational properties, they are not able to disperse the sun's rays.
  • Cloths do not protect from precipitation. At the same time, due to the increased humidity, the tissues begin to rot.

What color is better to buy plastic mesh?

At the moment, many manufacturers produce products in dark green. First of all, the production of such a shade evenly distributes heat and sun rays over a sheltered space.

Interestingly, with the help of a prism, you can find out that the light from the sun is divided into a spectrum of certain shades. This range includes green, blue, yellow and other colors.

Dark green shading nets for greenhouses best refract, reflect and absorb rays. They heat up in hot weather, but perfectly protect from heat. At the same time do not release heat from the sheltered space.

As various specialized studies have shown, the materials increase the yield up to 25-30%. At the same time, the size of the fruit increases, and the time for their full ripening decreases.

Important features of the use of products

Inside the artificial structures, the canvas is stretched under the roof. As a rule, products are laid in the form of a canopy on the surface of structures. At the same time, the material additionally protects coatings (for example, polycarbonate, glass, polyethylene film) from mechanical effects, wind, hail.

The shading grids get and for compact greenhouses, and for large farms. With a decrease in the temperature of the ambient air inside the artificial structures, up to 25% of the received heat is saved. As practice shows, the material laid on top of the structures is not removed in the fall and winter. After all, the canvas retains the original operational properties in the cold. At the same time, snow and ice melt faster on the material, reducing the load on the buildings.

Due to their low weight, the fabrics are easy to fit inside and outside. At the same time, products are often used outdoors for arranging a protected space where shrubs and fruit trees grow.

Additional scopes of modern material

As already mentioned, the canvases are actively used to darken a variety of greenhouses, greenhouses and other buildings in which there are shrubs, fruit trees, seedlings, vegetables. The shading nets are suitable not only for greenhouses, but also for arranging a cozy space for summer holidays and eating. For example, with the help of artificial fabrics, you can ennoble a gazebo or a veranda, because the canvases will effectively protect both from the sun's rays, and from the wind, and from annoying insects.

In commercial activities, materials are used to create summer venues for various restaurants and cafes. Sometimes products are used as decorative fences.

In city apartments and private houses, materials can be used to protect balconies and rooms from the environment. Artificial fabrics are used to create carports for vehicles - they also perfectly protect cars from foliage, dust, and twigs.

During the reconstruction of building exteriors and carrying out various repair work, the grids are suitable for creating inexpensive fencing for scaffolding. They can cover reconstructed facades and other surfaces. That is why shadow nets for greenhouses, gazebos, car parks, construction sites are selected, taking into account such characteristics:

  • cell sizes - the smaller the holes, the worse they let in sunlight,
  • appearance - mostly large manufacturers produce materials of a dark green color, but artificial red and blue-green fabrics are also on the market,
  • density - the denser the material, the stronger, more stable, heavier it is.

As practice shows, before buying it is better to get advice from a specialist who will help you select products specifically for specific operating conditions.

Shadow Product Differences

Regardless of the manufacturer, domestic or foreign, the networks differ among themselves in:

Power blackout. This figure varies from 45 to 90 percent. Light-loving plants such as tomatoes, cucumbers, pumpkins, melons, suitable material with a dispersion of 45%. In case of strong heat, such a grid will not save the residents of the greenhouse.

They are usually placed inside greenhouses. From the burning rays will need a network with a degree of shading from 60% to 70%.

For the shelter of the enclosing surfaces, for example, a fence, are products with a dispersion of 80 to 90%. Networks from 60 to 90% are usually used on the outside of greenhouses and buildings.

Material manufacturing. Raw materials for pritenyayushchy grids can be the following: - polycarbonate. It is considered the most expensive and durable for mesh shelter. It does not spoil and will last for several seasons.

The structure does not deteriorate under the influence of adverse factors.

  • polymer. The material is cheaper than polycarbonate. It has a lower density, but is perfect as a shelter from wind, rain, insects and the sun.
  • the cloth. This is the most budget option. The structure of such a mesh consists of foiled and synthetic yarn. The sun's rays are not only scattered, but also reflected from it. The net has one minus - it lets moisture through and rots afterwards. Such a network will not last long.
  • By color. The owner of the garden plot can get a grid for the greenhouse of any color. Color affects the yield and speed of fruit ripening.

Consider several colors in more detail.

Red. Promotes rapid flowering and ripening of fruits.

Blue. It has a retarding effect on growth and ripening. Suitable for growing greens (parsley, dill, lettuce, basil, etc.).

Gray. Protects against night frosts. It is used for flower crops.

Gray-green. Accelerates the process of ripening and increasing fruit.

Blue green Grids with a similar color are designed for year-round use. Protect from mold and sun.

Basic grid selection rules

Before you buy a shading grid for the greenhouse, you should remember a few characteristics that you need to pay attention to when buying:

The density of the material (cell size). For each type of plant fits its own grid. So for plants with large leaves and greenery is best to choose a grid with a dense structure. And for light-loving plants - the grid with a degree of darkening of 45%.

Environment of operation. If sunlight will constantly affect the fabric mesh, it will soon burn out. Under these conditions, it is best to use a polycarbonate or polymer mesh for the greenhouse.

Apply trellis nets to cucumbers. Their structure allows cultures to cling to antennae. Thus, the need to tie up the plants disappears by itself. Fruits hang before your eyes and do not need to look for them among the tops on the ground.

Appearance. If the future network will play a protective role from the sun in the house or on the street, its external qualities should be aesthetic.

Mounting grid for greenhouses

The material for shading begins to attach the bottom - from the base of the greenhouse. If there are no special fasteners, wire or rope is used for fastening. The network is lightweight, making it manageable by several people. In case of accidental fall on plants, the material does not break and does not press them.

As a backup, some gardeners use parallel bars made of wood or metal pipes. This method allows a more durable fixation of the product. Often used in conjunction with greenhouses that have an opening top.

Summarizing a certain result, I would like to say that scientists do not for nothing consider the grid for greenhouses an indispensable thing for growing crops.

Use a grid cape everywhere, both in large greenhouses and small greenhouses. Therefore, the grid for greenhouses are very popular among fans of the harvest of his garden.

Purpose of the shading grid for the greenhouse

A large assortment of nets shading the sun's rays is produced by domestic and foreign manufacturers. They are made of synthetic yarn with the addition of foil. Mostly the grids are green, but they are white, gray, etc. The grids differ in the degree of protection from sunlight. This indicator depends on the size of the cell. The larger it is, the less the mesh protects the plant.

The rate of solar blackout grids ranges from 45% to 90%. The synthetic material from which they are made is resistant to external influences and ultraviolet radiation. The principle of the grid is to reflect part of the sunlight and scatter the remaining radiation with a decrease in heat exposure. This creates favorable conditions for the development of plants.

Classification by use of shading grid

The shading grid can be used for various purposes. For example, to create protection from prying eyes of annoying neighbors, it is used to create a fence. Any mesh density is suitable for this, but high is preferred. She looks great in a duet with a grid as a sabbath. Fastening is best done with plastic clamps to the elements of the main fence. The grid shading for greenhouses can also cover arbors and canopies, scaffolding and facades of buildings. She will allow to hide from insects in summer days. There are various types of grids used for shading in crop production, which can be classified as shading grids for tomatoes, cucumbers, etc. The grid for cucumbers has a shading degree of 45%, for tomatoes –60%. More dense types of grids can be used for masking. For greenhouses using different grids, based on the cultivated plants and method of installation. 45% is suitable for intraclastic shading, and 70-80% is suitable for outdoor.

The main types of shading nets for density

Considering the climatic conditions and the characteristics of the cultivated plants, it is necessary to choose a shading net for the garden, on the basis of its density.

According to the degree of shading of the grid are distinguished:

  • 45% - intended for light-loving crops,
  • 60% - intended for shading from extreme heat. Used in the cultivation of lettuce, greens, tomatoes, eggplant, cabbage,
  • 70% - intended for outdoor shelter greenhouses,
  • 80% - designed for fences, fences. Creates a good shadow for car shelter,
  • 90% - is not used for plants, because it practically does not transmit light. Used for gazebos.

How do the grid for greenhouses are divided by color

New technologies that help regulate the ripening process and improve yields include the use of blackout nets that can change the spectrum of plant lighting. Depending on the color of the mesh, it is possible to speed up or delay maturation by 10-15 days. Also, scientists have found that by acting on various light waves, it is possible to regulate the main functions of the plant life cycle.

Previously controlled the amount of illumination of plants, depending on their characteristics, and now is the control of the wavelength of light and its impact on plant growth.

For example, red can accelerate, and blue, gray, or black can delay the flowering and ripening process.

Also, the color of the mesh affects different cultures in different ways. For example, for salad it is necessary to use nets of blue or gray. They contribute to the process of increasing green mass. For apple and peach orchards, a red mesh is better suited. Beneath it the fruits will be bigger and sweeter.

In order to achieve higher yields in greenhouses, thermal control and the provision of optimal lighting are necessary. To achieve these goals, manufacturers offer thermal screens that raise the temperature of plants at night and prevent its rise on hot days. With their help, photosynthesis is improved by increasing the amount of diffused light. These are gray shading grids.

Covering greenhouses with such nets, you protect crops from wind and frost, hail and sun, as well as reduce water consumption for irrigation and the amount of fertilizer.

This type of shading nets for greenhouses has a shading percentage of 69-72%, the conductivity of diffused light is 44% and is durable in use in different climatic conditions.

Рассмотрим, какую функцию выполняют сетки для затенения растений разных цветов.

  • Red - contributes to enhanced growth of the upper part of the plant, increases yield, accelerates flowering and ripening processes, increases the size of fruits. If we compare the total growth of a single plant under the grids of various colors, then the plant above the red grid will be higher.
  • Blue - has a retarding effect on the growth of plants, thus regulating the maturation of the crop according to the market demand. Dill, lettuce, parsley, greens contribute to the growth of green mass.
  • Gray - contributes to a small branching of the central branch of the plant, increases the area of ​​the leaf surface, protects against frost.
  • Pearl - positively affects the development of the plant, increasing the growth rate, the development of additional branches and the size of the fruit.

How to choose a shading grid for greenhouses

Based on a large range of shading nets, we will consider how to choose the right one. For a pritenyayuschaya grid to properly perform its function, it is necessary to select it based on the directions of its classification. The grid can be used both in large greenhouses and in small ones with any type of coating. It is valuable that at night temperature differences it retains up to 15-20% of heat. This is due to the reflection of heat fluxes. To lower the temperature in the greenhouse, it is necessary to use a complex shading grid with equipment for artificial fog and internal ventilation.

Installation of grid for greenhouses

Before you tighten the shading grid, you need to decide what method of ditching will be carried out, what materials and in what quantity should be purchased. To attach the sun protection net for plants, supports and clips are necessary. The mesh is very light, so a small number of people can handle it. In addition, holes for tension fasteners are located along the edge of the mesh. In the absence of fasteners, they can be replaced with wire or thread. The mesh has great strength, so breaking it is not easy. If you still have this situation, then worry about breaking further along the length is not worth it. When mounting it is necessary to fix the supports well, since they can damage the plants when they fall. The shade net for greenhouses is so light that it cannot harm them when falling on plants.

Wooden or metal structures can be used as supports. Due to its structure, the grid does not inflate and does not disrupt the wind, so it can be mounted in a greenhouse with an opening top. On hot days, the temperature difference under the net and outside is 15 degrees. In addition, it allows water to pass through and protects the crop from wind and hail.

Features of the use of shading grid in the greenhouse

The grid for shading is effectively used in greenhouses to control the temperature in the structure and protect the plants from the harmful effects of the scorching sun and frosts. It creates an ideal microclimate in the greenhouse, which contributes to the favorable development of seedlings. Scientists have shown that the use of the grid when growing tomatoes increases the yield by 20%. It is used both inside the greenhouse and covered outside. If the greenhouse is covered with a film, the net will protect it from wind breakage and hail destruction. If the greenhouse is large, it is advisable to use automatic shading control.

A wide range of nets and their low cost lead to their mass use for growing plants. They will not have to be convinced of their effectiveness and expediency of use for a long time.

The main types of materials for sunscreen mesh

Experts believe that the following materials are optimal for the manufacture of shading mesh:

The highest quality and expensive mesh for shading plants, made of polycarbonate. It is very durable and can withstand various aggressive external factors. And also such grid for a kitchen garden does not spoil and does not decay for many years. During operation, the properties of polycarbonate are not lost.

The following type is the shading grid for greenhouses from various polymers. These materials are quite durable, however, due to their low density and low cost, they are very cheap. Shade net of this type can keep in direct sunlight and pests, and also protects plants from strong wind and precipitation.

The most simple and cheap is the mesh of fabric from the sun. Such material can afford any gardener. The shading net for plants from fabric has the small term of operation because because of a large amount of moisture material quickly decays. However, this product can be used for other purposes on the plot, and not just to create a shade in the greenhouse.

How to choose a grid color for shading

Now on the market there are many varieties of grids for blackout, which differ not only in material but also in color. This parameter can also be considered very important, because color can influence many factors that relate to growing plants in a greenhouse.

Experts advise buying a shading net of such colors:

  • blue green
  • gray green
  • gray
  • red.

Blue-green shading nets are the best option for greenhouses, in which vegetables are grown throughout the year. This color will be able to optimize the internal microclimate and will maintain it at the required level. And also the grid of this color rather well protects crops from sunburn and mold when large amounts of water get on the leaves in the daytime.

It has been experimentally proven that the use of gray-green products in greenhouses can accelerate the ripening of fruits and increase their size. Similar effect is obtained due to optimization of the microclimate and the receipt of the greatest amount of sunlight in the greenhouse.

The gray color of the material is optimal for high-quality protection of ornamental plants and flowers. Scientists argue that such a shade of shading mesh will help the rapid growth of foliage, the development of stems and the appearance of buds. However when it comes to fruitingthen this color has no effect on this process.

It is worth noting that the gray garden net is able to protect crops from the slight frost that is possible at night. That is why it should be applied in late autumn and in areas with a non-permanent climate, where even in summer there may be slight frosts.

Red shading grid It is considered a good option for high-quality protection of garden and garden plants during the fruiting period, because it is capable of activating the process of forming a large number of flowers, the ovary and the rapid ripening of fruits. When red material is applied, the plants bloom much faster. As a result, a gardener will be able to harvest in a greenhouse much earlier than in an open area of ​​soil, which is exposed to harmful sunlight.

Red shading mesh able to increase the number of fruitsas well as their size. However, you need to remember that this shade can provoke a rapid growth of shoots. In other words, it will be necessary to cut vegetables and horticultural crops much more often.

Material Advisory Tips

To choose a quality product for shading, you should pay attention to simple and useful recommendations from experienced professionals, because when choosing such a device you need to take into account many factors, for example, the purposes for which the material is purchased, types of vegetables and garden crops, as well as some features climate in the region.

Great influence on plant growth may have cell size of the product. When they are quite large, then the amount of transmitted sunlight and thermal energy will be rather big. For example, to grow cabbage, lettuce and other plants with large leaves, it is worth buying a shading net with small cells that can provide a good shade. Because these cultures are rather shade-tolerant and in the shadows grow much fasterthan in the open sun.

It must be remembered that the more solar energy will fall on the device for shading over time, the better the product you need to buy. Colored fabric nets can quickly burn out in the sun, so after a short time they will lose their useful characteristics. For permanent use in an open, sunny place, preference should be given to polycarbonate or various polymers.

To protect the veranda well and balconies from the sun's rays, it is worth buying a fixture that will most suit the interior of an apartment or a country house. In this case, it is necessary to give preference to products that are able to protect the room from direct sunlight and various precipitation. In other words, the net from the sun is a good and cheap device that will be useful not only in the garden, but also on vacation.

Choosing a covering sunscreen is a very responsible business. That is why it is worth spending a small amount of time and learn all the useful properties of materials and their characteristics, as well as listen to the useful advice of very experienced gardeners. In this case, the person will not regret that the product for shading and sun protection does not fulfill its intended purpose. After selecting the material, it is imperative to familiarize yourself with the rules for its use and installation. Otherwise, the device can be spoiled during installation or operation.

Shading net becomes indispensable when growing plants in greenhouses and open ground. In addition, this modern material allows you to accelerate the melting of the snow mass, which greatly reduces the snow load on the greenhouse design and prolongs the life of the snow. Excellent strength indicators make the shading net durable, and its average cost in our country is quite affordable for most gardeners and gardeners.
