Structure type greenhouse: the rapid development of greenhouses, now the country has to be thin-walled steel fabricated in greenhouses. It is a factory for the production of goods by the standard specifications, the use of matching supply units. Production shed-type specifications are 5.4 m, 6 m, 8 m, and 10 m span steel vegetable greenhouses, height 2.4 m, 2.6 m, 2.8 m and 3.0 m. This shed-type structure, with certain specifications, reasonable structure, durable, easy handling, easy to move off exchange. Features greenhouses: the greenhouse air component. In the low season, the price of vegetables, steel shed construction, greenhouse insulation often closed, it is easy to accumulate toxic gases, such as ammonia, nitrogen dioxide, sulfur dioxide, ethylene and other harm. When the ammonia reaches the greenhouse vegetable steel shed when 5PPM cost, plant leaf tip will produce soaked spots, then black dead; when nitrogen dioxide reached 2.5-3PPM when the green leaves of the occurrence of irregular white spots, serious In addition to the veins, the whole leaf were bleached.
