A: Actually not! Only in certain operating environments and for special planting crops, it is necessary to build some large greenhouses. It is a wrong trend for farmers to blindly expand the shed area. Considering greenhouse environmental regulation, crop growth characteristics and economic benefits, the optimal scale for greenhouse construction is 7 to 9 meters span and 60 to 80 meters in length. ,
When the span of the greenhouse exceeds 9 meters, that is, when the width is too wide, the degree of arching of the shed is reduced, which can lead to excessive light in front and poor ventilation conditions, and crops are prone to pests and diseases. If it has been built, the front part can be properly pressed down during the film change to increase the degree of camber for ventilation; or a layer of mulch is attached to the front part of the third wire, and the shed is pressed to the front ground to avoid The front part is drastically warm. When the temperature is relatively high, you can increase the width of the vent to increase the amount of air.
When the greenhouse is too long, it is not conducive to ventilation and ventilation. Especially when there is strong wind, the temperature at the shed door is significantly lower than that at the shed, even after the vent is closed. At the same time, the length of the greenhouse will inevitably lead to inconvenient operation of the farming, and the distance between the front and the back is too large, which is easy to cause fatigue. If it has been built, use a new plastic film to make a partition in the middle of the greenhouse, which can be directly attached to the column, but it must be directly connected to the top of the greenhouse to reduce the air circulation on both sides.
