Greenhouse construction ultimate natural ventilation system also includes a greenhouse roof design, you can make the maximum air circulation, greenhouse construction so that the indoor temperature close to the outdoor temperature. Greenhouse construction and mechanical ventilation is not possible to make such a large amount of air flow to achieve the same effect. When the installation Insect greenhouse ventilatory efficiency in this layer must take into account factors as insect nets often than the inlet area should be large, intelligent greenhouse construction, prevent a lot of the incoming air. Greenhouse construction Irrespective of the ventilation inside the greenhouse building greenhouse smooth air flow is very important, because the only way the plant is similar to the surrounding environment, high density greenhouse construction, plant growing to neat line. So in order to facilitate the flow of air level, also need to install the fan. The new greenhouse construction of cold-rolled rectangular steel arch, compressive strength, modern greenhouse construction, single arch net pressure can reach 250--350 kg. As a result of flow line design, wind resistance greenhouse building strong, can withstand 29 m / s wind speed (10 wind). Greenhouse building addition, as is the use of rectangular steel tube, is improved arch support force and compressive strength, especially for larger snow in Northeast and Northwest Territories. Greenhouse construction budget, high density greenhouse construction, Guang-sheng agriculture provided by Shouguang City Agricultural Machinery Co., Ltd. Guang-sheng.
