In greenhouse construction, when insulation was some construction is permanent in nature, such as pillars and so on. However, some products require from time to time to promote the re-laying insulation should be, for example, the greenhouse film products are often subject to the sun and rain, easily damaged, and through a lot of market research, the product's useful life is generally two to three years So we should always replace the greenhouse film. Replacing the time to pay attention to some issues where these matters are introduced. 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, the 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 should hit the air duct insulation is then built greenhouses electric Otherwise, 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, you should add the right amount of sand, 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.
