How to control the humidity in the greenhouse?

The air humidity in greenhouse has a great influence on the transpiration of plants in greenhouse. If the air humidity is relatively high, transpiration will be weakened, which will directly lead to the decline of plants' ability to absorb water and transport nutrients. If the temperature in the greenhouse is high and the transpiration is weak, the plant leaves can not be properly cooled, which is likely to cause plant leaves to burn. If the air humidity is too low for a long time, the water in the blade will be insufficient due to the great difference between the internal water pressure and the external water pressure, resulting in blade tip necrosis.

Temperature and humidity are very important for greenhouse planting. Master Jiu Chun briefly introduces the methods of reducing air humidity and increasing air humidity.

First, methods to reduce air humidity.

1. It is a common method to reduce the air humidity by strengthening the air circulation in the greenhouse so that dry air and wet air can circulate with each other through air circulation.

2. Increasing the greenhouse temperature properly can accelerate the evaporation of water, thus reducing the air humidity.

3. Increase the light, and the light will also evaporate the water in the air.

4. Changing the number of sprinkler irrigation and spraying is also an effective way to reduce air humidity.

5. When necessary, dehumidify the room with a dehumidifier.

6. Put desiccant in the corner for dehumidification.

Second, the method of increasing air humidity

1. Wet curtain method can not only reduce the temperature in the greenhouse, but also significantly improve the humidity.

2. Sprinkler irrigation method, which is a commonly used humidification method to increase soil or air humidity through sprinkler irrigation.

3. Keep a certain tightness, so that the indoor air circulation is not too fast, and keep the humidity in the greenhouse.

4. Using a humidifier is also a good choice.

The control of temperature and humidity in greenhouse is a thorny problem faced by greenhouse owners. Jiuchunjian greenhouse temperature and humidity monitoring system can help users to monitor the air humidity in the greenhouse in real time and find the environment where plants grow.

The greenhouse monitoring system built in September can collect environmental parameters such as temperature, humidity, light, soil temperature, soil humidity, CO2 concentration, temperature and so on 24 hours.
