Fog in the shed is generally caused by high temperature and high humidity in the shed. In winter, due to the low outdoor temperature, the temperature in the shed is also lowered. It is difficult for the water vapor to condense and fall down. This creates a fog.
To eliminate fog in the shed, there are generally the following methods
One. Use anti-drip anti-fog film
The non-drip anti-fog film has obvious no-drop effect and anti-fog function, and can reduce the air humidity in the shed. At the same time, it has the characteristics of high light transmittance and warm temperature, and can catch crops to increase production and early maturing. It can significantly reduce crop pests, reduce the amount of pesticides, and reduce pesticide contamination of crops. If the film for the greenhouse is film-free, the fog should be smaller or not even.
II. Changing cultivation methods
The cultivation method will also have an impact. Pay attention to the way of cultivation, ridge cultivation, mulch film coverage will be better.
Three. Reasonable watering
Reasonably watering, strictly control the amount of water, appropriate air release after each watering, timely soil loosening.
four. Timely ventilation
When the weather is good, it should be ventilated and ventilated. When it is ventilated, the temperature and humidity in the booth should be observed at any time to prevent the temperature from dropping and freezing the vegetables.
Fives. A common and very effective method for growers
The beans were beaten into bean juice and sprayed onto the shed film. A medium-sized shed used about a pound of beans and two sprayers of water to spray on the inside of the greenhouse membrane.
