The need to maintain the temperature inside the greenhouse, the first should keep grass thatch or dry is a greenhouse insulation. Secondly, it is time once the temperature inside the greenhouse below 6 degrees Celsius, it is necessary to use burning stove for heating. Need to effectively reduce the humidity inside the greenhouse, sudden cold weather in winter, the growth rate of plants usually relatively slow power plant root activity is relatively small, so small plants need water, so farmers should try not watering, if Watering should be in the film, then watering, do not pour the flood, but also chasing instant dressing fertilizer, and the concentration is lower. 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 should hit the air duct after construction greenhouses, cold insulation otherwise be due to poor ventilation, can cause serious crop diseases, while too much snow in winter also has damaging effects on the greenhouse. Fourth, the construction of greenhouses dedicated to the best insulation is sandy loam, so soil ground temperature is high, the growth of beneficial crop roots. If the soil is too sticky site insulation should be added 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.
