Lutrasil, plant protection covering material


Many regions are geographically located in the zone of risky farming and in order to obtain a harvest, plants need protection from adverse weather conditions and weeds. In the memory of many gardeners, there are still those times when garden and garden plantings were covered with improvised materials, such as boards, roofing felt, roofing felt, burlap. With the development of the chemical industry, the production of various materials for plant protection has been established.

They were distinguished by their strength, durability and other parameters.

One of the modern examples is lutrasil, a covering material for the garden and vegetable garden. It has certain properties and has several varieties. To understand what it is, it is worthwhile to familiarize yourself a little with modern technologies for the production of such materials and their main characteristics.

Nonwovens. Agrotextile

Everyone knows that any fabric material is created from threads that are intertwined with each other in a certain way and form a canvas. In modern chemical production, a technology has been mastered for producing threads from polymeric materials and connecting them with each other using:

  • temperature regime, that is, by thermal methods
  • using physical methods (needle-punched)
  • using chemical methods of combined techniques

Nonwovens got their name from various methods. connections that exclude the way of weaving. Nonwovens are made from the following natural raw materials:

  • linen
  • cotton
  • wool

From chemical fibers:

  • polyamide
  • viscose
  • polyester
  • polypropylene
  • polyacrylonitrile

Nonwovens made of chemical fibers are widely used, including in the professional and amateur growing of fruits, berries, vegetables, flowers. They are collectively called agrotestyle. The main purpose of agrotextile is to protect and shelter plants, as well as to mulch the soil under the plants and between plantings. The most famous agrotextile is called spandbond. It is produced by hot blowing polymers. The purpose of the spandbond depends on:

  • density
  • weather resistance
  • resistance to abrasion and crease
  • breaking load resistance

An important characteristic of spunbond for use in agriculture is its resistance to damage from sun damage. Special UV stabilizers are added to the polymer melt. It is worth saying that agrotextiles made from polypropylene using a technology called spandbond are called differently in different countries:

  • Ukraine - agrofibre, AGREEN
  • Germany - lutrasil, LUTRASIL
  • France - agril, novagril, agril / novagril

Given the fact that earlier agrotextiles were most often imported from Germany, its more familiar name in amateur plant cultivation is lutrasil.

Lutrasil, its types

One of the main characteristics when choosing lutrasil is its density. It is usually indicated by numbers next to the name, for example:

  • lutrasil thermoselect 17
  • lutrasil thermoselect 23
  • lutrasil frostselect 30
  • lutrasil frostselect 60

The lightest and thinnest with a density of 17 grams per square meter. It looks no denser than a cobweb. Able to protect from frost down to - 2 degrees. The material with a density of 30 g / m2 keeps frost up to -6 and serves as protection from heavy rain, wind and hail. Some of the densest options for lutrasil, with a density of 42 and 60 grams per square meter, are suitable for creating greenhouses and greenhouses. Separately, it should be said about Lutrasil 60 UV. It is dyed black by adding carbon black, elastic and impervious to the sun. If it is spread on the garden bed, then the weed vegetation under it does not develop. Thus, depending on the density, other characteristics, lutrasil has four main purposes:

  • protection against unfavorable temperatures protection against atmospheric agents
  • soil mulching
  • weed control

When choosing a lutrasil for a summer cottage or garden plot, a combination of price, quality and durability is important.

Mulching

It is customary to mulch paths, aisles and the plantings themselves with black lutrasil.

In the spring, the bed prepared for planting crops is covered with black lutrasil and cuts are made into which the plants will be planted:

  • strawberry
  • bow
  • tomato
  • cucumbers
  • other cultures

Watering them is carried out in the same holes. Condensation does not collect on lutrasil, excessive dampness does not form under it, mold does not appear and the earth remains loose. Nowadays, there is a two-color non-woven material for mulching beds. The top side is white to prevent excessive heating of the root system. When creating decorative paths, strips of lutrasil are laid under the main coating. This prevents weeds from growing on the paths. The average service life of a mulch coating is three years.

Protective cover with lutrasil of plantings

Lutrasil with a density of 17 g / m2 is used to shelter the seedlings of thermophilic plants from frost from late frosts not exceeding - 3 degrees of frost. From the denser version, tunnel shelters can be arranged. Lutrasil with a density of 40 - 60 g / m2 is used for the construction of greenhouses and greenhouses. It is important that under the non-woven coating there is an unhindered penetration of air. If pollination is necessary, it is very easy to remove it for a while. The denser the lutrasil, the longer it serves on the site. Plants grown under such shelter develop better and yield earlier crops. To see this, it may be worth making small experimental beds and greenhouses out of lutrasil.
