A huge amount of modern materials makes it possible to equip our everyday life as conveniently and functionally as possible. For example, there is such material as lutrasil. What is it, those who have to work in agriculture or on their personal plot know this. This is a synthetic material of non-woven structure, which is made of polypropylene, widely used in agriculture and homestead farming.
Types and Features
Lutrasil film there are two types of structure - fibrous and mesh, and in terms of color - white and black. The main purpose of this material is to protect plants from the effects of natural conditions, primarily from frost. Depending on the thickness, it can be used for the following purposes:
- to cover the early crops in the spring;
- protect plants from frost and fog;
- cover greenhouses and hotbeds;
- to shelter young coniferous trees, as well as rose bushes and rhododendrons in the country.
When choosing a covering material for lutrasil, you need to pay attention to its density. So, the numbers 18 g / m², 23 g / m² indicate that it can be used to protect plants and crops at temperatures up to -3 ° C. The beds need to be covered immediately after seeds have been sown or seedlings planted in the ground. The edges of the material can be fixed with stones.
A density of 30 g / m² and even 40 g / m² allows the use of lutrasil in freezing up to -7 ° C. Such a film can both cover plants and externally cover greenhouses. But the material with a density of 60 g / m² suggests that it will be used as wind protection in open areas, which is ensured by the strength of the film.
Where is lutrasil used?
what it is a very necessary material for a garden, many amateur gardeners know. For example, if it is necessary to mulch the soil, it is better to use black material , since it will help warm the earth. But most use the material specifically for sheltering plants for the winter, for example, many roses loved by many. This method of shelter has many advantages. Firstly, the material is quite inexpensive. Secondly, during storage it takes up very little space, and you can use it for quite a long time. However, lutrasil should also be used competently.
Lutrasil and roses
To begin with, it is worth remembering that roses can withstand temperatures up to - 8 degrees. But if frosts intensify, then already in November you can do sheltering plants. To do this, they are first cleaned of unnecessary leaves. It is necessary to use a film in two, and even three layers of the highest density. So you can be sure that the plants successfully wintered. Another important point is that the larger the area you cover, the warmer your plants will be. At least one square meter needs to be covered, but it is better to expand the area: in this case, the earth will give off more heat, and your roses will withstand even in severe frosts.
If the roses are climbing, then they must be carefully tied in bunches, and then bent to the ground. True, it is imperative to lay, for example, boards or logs on bare soil, so that during the thaw the branches do not get wet and do not deteriorate in a puddle. Some hybrids of roses do not bend, so they should be trimmed a little - up to 50 cm from the ground maximum. Ideally, lutrasil should be laid on arches or props so that under the yoke of snow your flooring does not bend and press on the plants.
The properties
Lutrasil (what this, we have already determined) is the optimal solution for use for covering purposes. It is light, soft and at the same time dense, and it was created in Germany just in order to cover various crops in agriculture in spring and summer. The properties of this film far exceed the quality of its analogues:
- It protects from frost from -2 ° C to -7 ° C, if covered in two layers.
- Promotes plant growth if so-called physiological soil drought is noted.
- It passes moisture and air well, providing plant growth.
- Plants are well protected from overheating.
- It has high light transmission.
- Serves as a reliable protection against birds, insect pests.
- It does not require the use of frames and arcs during installation.
How to use?
The beds are covered with lutrasil immediately after the seedlings are planted or sown. The edges of the material should be sprinkled or laid with stones so that the wind does not blow off the film. If the plants do not need to be pollinated, then it can be left on the ridge until the harvest. Only occasionally can the edges be raised to allow plants to grow. For the period of pollination, the film is removed. By the way, you can water the plants directly through lutrasil, without removing it.
It is possible to use the material for sheltering greenhouses, unheated stationary hotbeds, as well as as an additional coating of plants. This will protect the crops from frost and get an earlier crop. Using greenhouses, you can save on heating. Lutrasil black non-woven is perfect for heating the soil and growing crops that require careful care.
What to choose?
As already mentioned, today there is a huge amount of materials that can be used in agriculture. For example, many gardeners do not know what to choose - lutrasil or spanbond. Their doubts are understandable, since in most characteristics these materials are similar. But, for example, lutrasil is most often available in white and is used mainly for sheltering beds and crops. At the same time, spanbond is a black material that is often needed to mulch the earth immediately before planting plants in it.
In Europe, lutrasil film has been used for 20 years and it is popular just because of the ecological purity and naturalness of the fibers. Using it, you can create an enclosed space above the plants, which at the same time will provide them with everything necessary - light, air and water. Thanks to the creation of a favorable microclimate, vegetables, fruits and berries will grow much faster, providing their owners with an early harvest.
Spunbond Features
This is a reliable material that can protect plants from pests. Non-woven structure - the guarantee that covered plants will not be infected with various diseases. Due to the homogeneous composition of the fibers in the space under the shelter, a microclimate favorable for the growth of crops is created, while the precipitation is distributed evenly, and the air circulates constantly. Many gardeners note that by using black spunboards on strawberry beds, you can forget about a problem like weeds for a long time.
Where to buy lutrasil and spanbond?
As we already understood, both materials are great for using them as cover materials. You can buy such a film in specialized stores where various goods and materials for home and summer cottages are sold. In addition, you can always order delivery at the manufacturing company that manufactures lutrasil. That this is a very good and high-quality material, everyone already understood. In addition, it is an economical material, since you can buy it at a low cost. So, depending on the density of the fiber, lutrasil will cost an average of 2 to 24 rubles per linear meter.
Thus, both lutrasil and spanbond can be used as a covering film. Each of these materials has its own characteristics, and therefore, when choosing, it is worth considering for what purpose you are buying it.
