Any, even an experienced gardener or vegetable grower is not able to influence the weather. Sudden spring frost on the soil can greatly damage plants. Therefore, for their protection, it has long been customary to use covering material for beds.
It is difficult to say which of the types of protective covering products is better. Summer residents quite successfully use both the proven traditional burlap or plastic film, as well as new materials. These include materials made of polypropylene fiber, obtained by the technology of "spunbond", which are environmentally friendly light non-woven materials.
If the plastic film is absolutely air- and moisture-proof, then the spanbond creates a minimal barrier for the penetration of the necessary light, water and air through its pores.
The plants under it develop in a favorable microclimate, and you can water them directly through it.
Technology and application features
Spunbond technology is a method for the production of small diameter chemical fibers. They are resistant to acids, alkalis, microorganisms and have a small specific gravity. Here, chemical fibers are usually obtained by extruding (forcing) a polypropylene melt through a plurality of thin capillaries in a spinneret. Being laid on the canvas in a softened state, the threads (fibers) are glued together, and you get a finished non-woven fabric, often called spanbond, as well as the technology of its production.
Usually spanbond for beds is sold under such brands:
- Agrospan 17 or Agrospan 30
- AgroSUF 17 or AgroSUF 30
- Lumitex 17 or Lumitex 30
- Lutrasil 17 or Lutrasil 30
Apply spanbond in this way. Immediately, as soon as seedlings are planted or seeds sown, a roll of a covering sheet is unfolded on the bed and sprinkled with earth in several places along the edges. To prevent plants from being pressed down as they grow, the canvas is periodically lifted. Watering the beds and make water-soluble fertilizers directly through agroprotection.
This includes canvases with a density of 13 to 30 g / m2.
- They are covered with beds both by farmers in large areas, as well as gardeners or summer residents, since the canvases have low prices and their service life can be several seasons.
- They are the thinnest of all available analogues and serve as a good protection for young plants from heat or cold, including a short-term decrease in temperature to -2 ° С.
- They serve as an excellent protection of crops and seedlings from birds and insects.
- The structure of the nonwoven fabric is capable of transmitting light, air and moisture, while creating the required microconditions for the confident growth of plants.
- The agricultural cover will provide an abundant crop of vegetables, ripening two weeks earlier than usual.
Shelter of arc greenhouses and greenhouses
- For covering arc greenhouses and frame greenhouses, a non-woven fabric with a density of 35 to 60 g / m2 is used.
- They can also shelter seedlings of shrubs and trees from freezing in the winter.
- This cover passes air and water, and also protects plants from lowering temperatures to -3-4 ° C and exposure to cold mists.
- Under such protection, a microclimate favorable for the development of crops is created in the greenhouse (greenhouse), which leads to an increase in the period of their vegetation.
- The canvas has high strength; It is produced with the addition of a UV stabilizer, which extends its service life up to three seasons.
Available under the following brands:
- Agrospan 42 or Agrospan 60
- AgroSUF 42 or AgroSUF 60
- Lumitex 42 or Lumitex 60
- Lutrasil 42 or Lutrasil 60
How to protect plants from wind and frost
- The black covering spanbond material prevents the growth of weeds in the beds, and also protects the lawns from erosion by rains or drying out in the summer.
- Its use inhibits weeds, evenly distributes moisture in the soil under the canvas and contributes to the fact that the earth warms up faster.
- Gardeners use artificial mulch to prevent contact between berries and fruits on the ground.
- Agroprotection of this type can ensure successful overwintering of plants during a snowy winter. Tree trunks for winter are also covered with mulch.
The material has the highest density of all existing non-woven agricultural cloths - 40-60 g / m2.
It is usually sold under the brands:
- Agrospan 60
- Agril 60
- Lumitex 60
- Lutrasil 60
The covering sheet is used throughout the entire phase of the growing season. Rolls of bedspreads are rolled out before planting on previously prepared soil and sprinkled with earth in several places along the edges.
In those places where plants are planted, cruciform incisions or round cuts are made.
The use of agromulch
- reduces the amount of watering and evaporation of soil moisture;
- provides quick heating of the soil and constant maintenance of the required temperature;
- prevents soil contamination of fruits and berries, prevents decay and moldiness of soil and plants;
- limits weed growth, including perennial;
- reduces the application of herbicides and pesticides.
The soil covered with mulch does not undergo compaction, remains loose until the fruiting vegetation continues without any additional cultivation. Being left on the soil in winter, mulch serves as a reliable protection for plant roots from freezing. Its black color contributes to the absorption of thermal radiation. For the cultivation of heat-loving melons, this is very important.
As you can understand, all the numerous trademarks of covering non-woven spunbod materials have approximately the same properties, but different purposes, determined by their density.
Therefore, choosing a similar protection for a specific purpose (sheltering beds, greenhouses or mulching), pay attention to the two-digit number in the designation of his brand, which represents its "conditional" density.
