Cellular polycarbonate for greenhouses is produced various coloring today. Consumers can choose material not just transparent, but yellow, green, orange, all shades red from tomato to ruby. First, color polycarbonate – it is simply beautiful. But matter not only in beauty.
It is a little physics
At installation of the greenhouse with covering from polycarbonate units think of how to enter it in landscape of the site. Why then producers release panels, and not just transparent. Here it is appropriate to remember physics. From school course in this subject: sunlight consists of visible and invisible range of electromagnetic waves. These waves of various frequency smoothly pass each other. During rain if at this moment the sun looks out, it is possible to observe all range in the form of the phenomenon which is called rainbow. Every color has certain designation and wavelength which is measured in nanometers. These waves differently influence all live on the earth, in particular, on plants.
It is a little biology
From school course of biology: process of photosynthesis of plants is impossible without day sunlight is impossible. Radiation of electromagnetic waves influences growth of plants. And, various image. Each site of range, both visible, and invisible, carries out strictly certain role in photosynthesis of plants.
Ultra-violet radiation up to 280 nanometers is considered rather harmful to plants. It is called rigid ultraviolet. From influence of ultra-violet waves leaves turn yellow and dry up, growth points perish. Cellular polycarbonate has property to detain short UF of wave and to block their radiation for 100%.
Plants and range
Ultraviolet rays in the range of 280-315 nanometers are considered as useful to plants. They promote hardening of all cultures which are grown up in the greenhouse, increasing their stability to Holodov to factors. Ultraviolet rays in the range of 315-380 nanometers are necessary to plants too. They actively influence their growth and metabolism in fabrics. Panels from polycarbonate pass beams of this range. Further, since 400 nanometers, all violet-blue part of range promote forming at plants of fleshy leaves and fleshy which allow fully, all surface to absorb all range of range of sunlight. This range of range from 400 to 500 nanometers affects intensity of process of photosynthesis. In this range it is maximum. There is further green range of range which is not absorbed by plants. Receiving radiation from this part of range, they become sickly, are extended, photosynthesis in fabrics at influence of beams in the range of 500-550 nanometers strongly slows down. And the most valuable and useful to plants is the range of orange and red beams. All waves having length more than 600 nanometers promote the active growth of plants. The chlorophyll completely absorbs this range, forming large amount of carbohydrates. Vegetable cultures at influence of flowers of orange-red range grow quicker, develop better and considerably increase productivity.
