Urozhay agrofilm- increases a total productivity, doubles a content of C vitamin, forms stable root systems, stems

"Urozhay" agrofilm
- successful choice for hotbeds and hothouses

  • increases a total productivity of late vegetable crops by 15-45 %;
  • increases a productivity of early vegetable crops by a factor of 1.5-1.6;
  • makes it possible to harvest simultaneously during 1-1.5 months;
  • makes it possible to achieve two harvests of cauliflower and three harvests of garden radish and greens instead of one even in the middle zone;
  • doubles ( 2.10 - 2.25 % ) a content of C vitamin in peppers and lettuces;
  • forms stable root systems, stable stems, non-falling leaves .

     It has long been known that a spectral composition of light impinging a plant's green leaf affects its growth, and , as a result, its productivity. In this regard, visible lights are the most useful, whereas ultraviolet lights retard plants growth and excess of infrared light can cause burn and destruction of plants.
     In the result of many-years researches a way was found to derive maximum benefit from sun lights. Scientists proposed to use films with light-transforming properties as covering materials. In practice, such films proved them to be excellent ones.
     With time a technology was improved, generations of films changed.
     The "Urozhay" agrofilm is the last third generation of the light-transforming films. It differs significantly from previous analogues and is superior to them in strength , light-transforming properties , and ecological safety.
     Due to a special light-transforming additive in its composition , the "Urozhay" agrofilm absorbs ultraviolet lights in the range 0.28-0.4 mm, ( harmful for plants growth) and transforms them into useful radiation in the visual range of sun lights.
Positive results of the experiment      Besides, this film can reflect infrared light. As a consequence, under this film in day-time it is slightly colder and ,conversely, in night-time is warmer than under a standard film. This results in smoothing an average daily temperature profile, that ,in its turn, has a beneficial effect on plants growth.
     According to Norwegian Agricultural University's information , a rise of an average daily temperature from 15oC to 25oC in cultivating Farbiola cucumbers speeded up ripening by 1.6 day per every one degree and increased an average harvest in the first eight weeks after seeding transplanted by 0.54 kg/m per every one degree.
     In order that the effect of the use of the "Urozhay" agrofilm be maximum, it is recommended to cover plants at the earliest stages immediately after sowing. With this, an optimal microclimate for plants growth is created, which is very important for effective formation of plants' root system and hence for plants normal growth and fruiting.
     In other respects , agricultural practices do not differ from common ones.
     If the "Urozhay" agrofilm is applied inside glass hot-houses , a lighting with ultraviolet or luminescent lamps should be used because a standard glass almost entirely does not transmit solar ultraviolet lights. When ultraviolet lighting is not used, the "Urozhay" agrofilm will only work for heat conservation.

The light-transforming "Urozhay" agrofilm includes:
  • a top-grade polyethylene or its very stable co-polymers;

  • organic light-stabilizers and inorganic light-transformers and light-diffusers;

  • metal-film contact stabilizers;

  • infrared absorbers and reflectors.
