Dehumidification Measures In Greenhouse

Air humidity within the greenhouse is often larger than an open field, and in the wet state, therefore, management is dehumidifying air humidity within the greenhouse. During production the measures of dehumidification are summarized as follows:
   
Dehumidification Measures In Greenhouse

1.Ventilation is a good way for dehumidification.
Ventilation must be carried out at high temperatures, otherwise, it will cause the indoor temperature drops. If the air temperature drops too quickly, in time to close the vents to prevent temperature plummeted causing vegetables suffer damage. Greenhouse temperature and humidity meter will also be helpful.

2.Proper watering
Watering is the main factor causing indoor humidity increases. Production in winter and spring you can choose a sunny day, ditch watering, plant watering, or irrigation under the surface of plastic mulch film. Watering should strictly control the amount of water in order to prevent the indoor humidity too high. After each watering, in time for ventilation and hoe soil to reduce soil moisture, which can also reduce the air humidity.

3.Mulch film 
Plastic film mulching can reduce soil moisture evaporation, which is an important measure to reduce indoor air humidity. For example in sunlight the greenhouse in the size-and-long distance, way to cover double Ridge mulched with plastic film, under the water when the water film in a small ditch flows. Mulch film can prevent the evaporation of moisture, thus prevent the water inside air humidity after the substantial increase.

4.Warming to dehumidified   
By using this method can not only meet the needs of vegetables on the temperature and also lower air relative humidity. When the plants are grown with resistance, water closed-canopy temperature up to 30 degrees Celsius will continue 1 hour, and later ventilation and dehumidification. 3-4 hour later shed wet can be repeated when less than 25 degrees.

5.Use of hygroscopic
good curtain material moisture permeability and moisture absorption good curtain material, such as non-woven cloth can prevent surface condensation, and prevention of dew on the plants, thereby reducing the air humidity.

6.Natural moisture 
Can use straw, wheat straw, lime material spreading in rows so as of adsorption of water vapor or mist, and achieve the objective dehumidified.

7.Row dehumidification 
By cutting off the soil capillary can avoid soil capillary water rises to the surface, to avoid a lot of soil moisture evaporation.

8.Increase the amount of light 
Increase the amount of light can increase the room temperature, when room temperature rise, with frequent ventilation, to achieve the objective dehumidified.
