Greenhouse film svetamaksimova POLYSVETAN.
Greenhouse film POLYSVETAN converts the energy of solar radiation (reduces the proportion of the ultraviolet and increases the proportion of red component of the solar spectrum) and increases the yield of agricultural crops: cucumbers, lettuce, spinach 20-50 %, cabbage, tomatoes 20-40% shade-loving plants: ginseng, lemongrass, raisins by 20-60%, strawberries by 50-100 %, water 64 %.
Used in agriculture by domestic and foreign photo-stabilized film with fillers have a number of shortcomings: passage of sunlight lose up to 30-40% of the photosynthetic active radiation (400-700 nm), used in international practice, the fillers are unstable to sunlight. POLYSVETAN – svetamaksimova (policecanada) greenhouse film based on polyethylene and luminescent fillers that convert ultraviolet and blue-green components of solar radiation radiation in the red region of the spectrum for the purpose of additional energy “pumping” chlorophyll green sheet and provide significant crop growth.
Fotobrauzera greenhouse film POLYSVETAN – optical Converter of light, thanks to special additives, converts the energy of solar radiation (reduces the proportion of the ultraviolet and increases the proportion of red component of the solar spectrum).
Greenhouse film polysvetan converts the ultraviolet radiation with a wavelength of 290-380 nm is useful for plants in visible light 450-750 nm. The result of such a transformation is equivalent to increasing light intensity in the field is most useful for plants photosynthetic active radiation.
When illuminated with UV light greenhouse film POLYSVETAN painted in uniform red and transmits the red color, while the other is a simple film when illuminated with a UV lamp flow blue-violet light.
However, the use of film materials are currently limited to the private sector, because for the industrial production of agricultural covering material is the traditional silicate glass, and the most important task of greenhouses is to reduce energy costs, especially the cost of heat. Based on this developed methods the introduction of this additive in silicate glass and polycarbonate, which allows to obtain the above effect, including to raise the temperature of the indoor air by 3-4 degrees, improve working conditions, efficiency and staff well-being, due to the known beneficial effects of red light.
– environmentally friendly method of increasing the yield of agricultural crops:
– cucumbers (20–50 %),
– cabbage (20–40 %),
– tomatoes (20–40 %),
– lettuce, spinach (20-50 %),
– shade-loving plants: ginseng, schisandra, sultanas (20–60%),
– strawberries (50–100 %),
– watermelons (64 %),
– ripening of plants is reduced by 3-15 days, and rose – 20–30 days
– ensures optimum temperature in greenhouses, hotbeds and greenhouses with less energy consumption,
– reduction of heat losses and protection of plants from frosts down to -5°C,
– high profitability,
– resistance to sunlight.
