Greenhouse insulation was used in accordance with the family bedding made gradual improvement, the main role is to cover greenhouses around, play the role of wind and thermal insulation. Well known for the production of various crops have a very strict temperature requirements, and they are very strong for temperature sensing, not like us, once to twice the temperature difference is not much feeling. The crop is different, sometimes the difference would be suppressed once thriving agricultural crops are holding, so that the insulation must be in place. Now almost every greenhouse has a temperature gauge, they measure 24 hours of uninterrupted indoor temperature. Today small for you about some principles greenhouse construction, I hope we can pay more attention: an election open terrain, flat, or local greenhouse construction gentle sun, so where lighting is good insulation, ground temperature is high, convenient uniform irrigation. Second, should not be on the air in greenhouse construction, to reduce heat loss and wind damage to the greenhouse. Three, you can not nest downwind greenhouse construction, nest where the wind hit the plenum should build greenhouses and then, otherwise electric insulation was due to poor ventilation, can cause serious crop diseases, while too much snow in winter also has damaging effects on the greenhouse. Fourth, greenhouse construction in sandy loam best, so soil ground temperature is high, the growth of beneficial crop roots. If the soil is too sticky, add the right amount of sand should be wholesale insulation, and more organic fertilizer to be improved. Alkaline soil is too large, acidic fertilizer must be applied before the greenhouse construction to be improved in order to build after the improvements. Greenhouse insulation is widely St. agricultural machinery, Hunan insulation was provided by Shouguang City, Canton St. Agricultural Machinery Limited.
