? Greenhouse farming chickens, ducks, pigs, cattle and other livestock, the summer hot season prone to heat stress, resulting in the production of performance degradation, or even heat stroke, shock and death, for chickens, ducks, pigs, cattle breeding great harm Summer How to effectively control greenhouse temperature and humidity to chickens, ducks, pigs, cattle provide a comfortable environment for the growth that is the real problem faced by domestic farmers, to solve this problem the most effective and economical way is to change the traditional chicken, duck, pig, cow shed "transparent longevity Wu Dimo ??+ grass gate or insulation cotton + black plastic sheeting or shade net" covering structure dedicated to breeding black and white film! "The breeding special black and white film, the outer white and black, used Summer and autumn when the white side up, with a strong ability of reflected light, and black inward prevent light penetration through, play a role in cooling shade, greenhouse temperature than other sheeting and mulch should be reduced. winter use black face outward, white face, the black surface can dissipate heat above the cynicism, it can block in the white face and reflection shed most of infrared light (heat) to Pengwai radiation, and thus play a role in thermal insulation. farmed special black and white film with high thermal effect ensures that the surface temperature at night and in winter with good insulation effect, reducing the temperature difference. This versatile black and white film, inherited the leadership of Europe in five co-extrusion technology and 100% of technology transfer, fully mastered the five co-extruded technology, in each layer using different materials, the combination of these different material properties (advantage) is reflected in the final product, an intermediate layer is a thin film layer of dimming, and its function is to crops or animals without general light into useful light general types of farming to increase efficiency, while the intermediate layer may also play a role in thermal protection of the shed cool summer night in winter and heat.
