Features greenhouses: the greenhouse air component. In the low season, often confined greenhouse insulation, it is easy to accumulate toxic gases greenhouses monomer costs, such as ammonia, nitrogen dioxide, sulfur dioxide, ethylene and other harm. When the canopy up 5PPM when ammonia monomer greenhouses built plant will produce water-soaked spots on leaf tip, then blackened dead; when nitrogen dioxide reached 2.5-3PPM, the green leaves of the occurrence of irregular white spots, serious In addition to the veins, the whole leaf were bleached. Features greenhouses: the greenhouse air component. In order to prevent the accumulation of harmful greenhouse gases, you can not use fresh manure as basal, nor can not yet decomposed manure for fertilizer; prohibited the use of ammonium carbonate monomer greenhouses as fertilizer, urea or ammonium sulfate when used as fertilizer to be watered water facilities promptly after casing or fertilizing; fertilizer dosage should not be administered properly overdose; low season monomer must be properly ventilated greenhouses construction company, in order to remove harmful gases. In addition, the coal quality is better, to fully burn. Conditional use hot air or hot water heating pipe, the exhaust gas after combustion exhaust Pengwai.
