Covering nonwovens: types and selection criteria
Many gardeners are trying to plant and sow more quickly. In this case, they come to the rescue non-woven covering materials of foreign and domestic production. It can be different types of agrospan, spunbond, agrotex. They provide reliable protection from frost and create an optimal microclimate for the active growth of plants.
What are the types of paintings
The modern summer resident today has a huge selection of products to protect plants from the weather. Covering non-woven materials are presented in a very wide range, and among the most popular types should be highlighted:
Each of these types of materials has its own specific features that must be taken into account when choosing them.
What is the difference between covering fabrics?
Covering nonwovens look quite similar in appearance, but they are nonetheless different from each other.When selecting them, be sure to take into account the marking of the product, which is denoted by numbers. The higher it is, the denser the material. It will also be much better to keep warm.
The thinnest and lightest covering materials are well suited for frameless shelter. In addition, they have a very excellent light transmission, help to create favorable conditions for growing plants. And similar products can protect plants from pests and birds.
Covering non-woven materials with marking No. 23 have the same qualities as thinner products, but they are much stronger. To provide protection against severe frosts, products with markings No. 30 and No. 42 are ideal, as they help to ensure the best possible conditions.
It should be noted that without a frame, you can only use a lightweight non-woven covering material, and for more dense and durable products you need a reliable and stable frame. The most durable products are models with markings №60 and №80.
Quality of covering materials
The quality of covering non-woven material can be judged by several criteria.First of all, you need to take into account the presence of UV stabilizers, and also pay attention to the uniformity of density. It is best to select products of well-known manufacturers who have already established themselves in the market.
It is worth remembering that shelter is required not only for garden crops, but also for heat-loving young trees and shrubs. In addition, such material may be required roses. In this case it is worth picking up agrotex or agrospan.
Density of covering material
If you have a greenhouse, covering nonwoven fabric should be selected very carefully. In particular, this product varies in density. There are the following options:
Lightweight products are available only in white. They can be used without supports and laid directly on the seedlings immediately after its landing in the soil. Under this shelter a comfortable microclimate is formed. The material is particularly easy, it does not damage the stems, and the plants will independently lift the canvas from the ground as it grows. Such a shelter will help protect the planting from the sun, severe frosts and insects.
Medium density products are also white. They have a density of 28-42 g / m2. This material is ideal for covering greenhouses and greenhouses. They are covered with berries, shrubs, and crops for the winter.
Black nonwoven covering material is characterized by high density. This fiber is ideal for carrying out soil mulching. It prevents the germination of weeds. Not getting enough sunlight, they can not develop normally and just die. Seedlings need to be planted in a special slot. In addition, it is worth noting that the nonwoven covering material from the weeds is very well heated and provides the seedlings with the required heat.
White durable material is used for the equipment of greenhouses, it is stretched on the supports, as well as on the frame for the protection of plants. A modern innovative material is considered a two-layer canvas, the lower layer of which is black and the upper one is white. The black side of this canvas is laid on the soil to avoid the appearance of weeds. The white side will reflect light. In this case, the harvest will grow much faster.
The appointment of covering material
Nonwoven covering material for greenhouses enjoys great demand among summer residents, as it maintains a comfortable temperature and humidity necessary for growing a rich harvest. Taking into account the use of modern innovative technologies, covering materials allow:
- increase yields;
- protect plants from frost;
- retain moisture in the soil;
- reduce the effort involved in processing beds.
In order for such a product to be useful, you need to choose the right non-woven covering material for the beds. When buying the desired option, you need to take into account many different parameters.
Lutrasil is a nonwoven covering material for beds, which looks like a spider web. Its advantage lies in the fact that no condensate forms under it. If necessary, it can be left on the soil for a long time.
The density of lutrasil may be different. The lightest option is considered to be a thermoselective that can withstand frosts up to -2 degrees. A more dense option is frostselekt, which helps protect seedlings from hail, pests, birds and frost.
Non-woven covering material in black color provides the greatest degree of protection, so it is most often used when planting plants in the soil, having previously made holes in the canvas. It helps to create the most favorable thermal conditions at the roots.
In the past few years, non-woven covering material spunbond began to be in great demand.
As a result of a special method of manufacture, a wear-resistant, durable and durable material is obtained, which has found wide application in various fields of agriculture. Depending on the density of the canvas, it can be used in open or protected ground. There are main areas where this product can be used. It is used for:
- accelerating the warming of the soil;
- getting the most early shoots;
- protection of the surface layer of soil from drying out;
- protect plants from severe frosts.
Before applying the sanbond to protect plants from bad weather conditions, you need to consider its main technical characteristics:
- good breathability;
- low weight;
- homogeneous structure;
- resistance to adverse factors;
- not subject to putrefactive changes and bacteria.
Spunbond can be used at any time of year. In the spring, it contributes to a better warming of the soil for early sowing. In addition, a high density spunbond can be covered with greenhouse and greenhouse frames.
Agril is a covering material with a high degree of light permeability, but it also dispels ultraviolet light well. That is why in the hot season the plants will not bathe, and during frosts they will not overcool. The cloth well passes air and moisture. In addition, it is durable and convenient to use.
Agril helps protect the soil from erosion, the formation of crusts on the soil, compaction, shorten the period of ripening plants. Black agril does not transmit light and eliminates the need for frequent weeding.
Covering material agrospan suitable for use at any time of year. This canvas brings together the best qualities of other products. In the cold season, it helps protect seeds, seedlings and seedlings from frost.In the summer, it provides protection against excessive ultraviolet radiation.
Agrospan is a synthetic fiber that looks like flizelin. Manufacturers produce canvases in black and white. White material is ideal for hiding seedlings in a greenhouse or greenhouse. The black material is used for soil mulching. It provides protection from weeds and pests.
With the help of new technologies used in the production process, get a strong and durable fabric. It has the following advantages:
- creation of the required microclimate;
- protection against overheating and excessive cooling of the soil;
- reduced watering;
- protection from pests and diseases;
However, this fiber has certain disadvantages. The main disadvantage is the low level of insulation, which is very bad for the growth of heat-loving plants.
Lumitex is a transparent material of various colors that helps to increase the flow of light. At the same time, the web retains and reflects part of the infrared radiation, thereby protecting the plants from overheating.It very well passes moisture and carbon dioxide.
This material looks quite unusual, as it is presented in various colors and has a fluted texture. This product is very convenient to use and is suitable for hiding strawberries and cucumbers. It can last for a long time.
Mulch covering material
Mulching material for the shelter of plants is very often used in gardening. It can be organic and inorganic. Organic canvas can gradually rot. The soil covered by it is enriched with useful substances. Thus, the characteristics of the soil and its acidity gradually change. Given this fact, it is necessary to apply organic mulch very carefully.
Inorganic covering material performs an additional decorative function. As mulch, you can use color and black film, which can be easily combined with decorative plantings.
Polycarbonate coating is the best alternative film for greenhouses. It is a reliable material that is able to protect plants from rain, bacteria, wind, while creating the best conditions for optimal growth and development of garden crops.
Polycarbonate, in essence, is a plastic sheet, having inside the cavity, which are somewhat like honeycomb. Such sheets differ in the high durability and ease.
Cover materials reviews
According to customer reviews, nonwovens for plant protection and greenhouse cover are characterized by high quality and reliability. Many prefer to use polycarbonate as a cover for the greenhouse, as this canvas provides protection from adverse weather conditions, and also supports the full growth of plants.
In addition, many say that non-woven material is ideal for growing strawberries, as spunbond helps provide protection from weeds and helps to create the most optimal conditions for growing garden and garden crops.
