The optimum soil moisture and air humidity for the growth of camphor are 70%. When the humidity is too small, the temperature is easy to rise, and the alfalfa sprouts are accelerated, which affects the yield and quality of axillary buds. The humidity is too high, the axillary buds are slow to germinate, the flavor is poor, and the disease is prone to occur. In order to keep warm, the shed room is often in a closed state. The indoor air humidity is large, generally 80% to 90%. When the temperature is low at night or in the rainy day, the relative humidity reaches 100%, which is saturated and needs to be dehumidified. When the outside temperature rises in the spring and the light is enhanced, the temperature and light intensity in the shed increase, the humidity of the air decreases, and the humidity is too low (relative humidity is less than 40%), so humidification is required.

Main measures for dehumidification:

(1) Ventilation and ventilation is the most economical and effective way to reduce the air humidity in the greenhouse. Ventilation at noon on sunny days can reduce the humidity in the greenhouse to 40%.

(2) Increasing the temperature Generally, for every 1 °C increase in the indoor temperature, the air humidity drops by about 5%. When the room temperature is 20 °C, the air humidity is 70%, and at 30 °C, it drops to 40%.

(3) The ground cover is to reduce the evaporation of surface water, and the mulch floor cover the mulch film, which can reduce the air humidity by 10% to 30%, cover wheat straw and straw, etc., and also have good dehumidification effect.

(4) The dehumidification device has devices such as dehumidification, moisture absorption, and heat exchange ventilation.

(5) Watering method The watering method such as drip irrigation can effectively control the watering amount, thereby reducing the air humidity in the shed.

The main humidification measures are:

(1) Spraying water and humidifying to replenish moisture in the indoor floor and air.

(2) Spray humidification is generally sprayed using a low pressure spray system.

(3) The use of the wet curtain device can reduce the temperature in the greenhouse and increase the indoor relative humidity to 75% to 80%.
