Dehumidifier Knowledge:

How does the dehumidifier solve the problem of greenhouse dehumidification with high humidity and multiple hazards?

Closed greenhouses are often airtight. Excessive air humidity in plastic greenhouses will inhibit the normal transpiration of plants, slow down the normal water circulation of the soil, induce and aggravate the occurrence of pests and diseases, and easily cause flowers and fruits to fall. So how do you reduce indoor air humidity?

1. Choose no drip film. No drip film can reduce the surface area of water, which is beneficial to light transmission and temperature increase.

2. Spraying drops on the surface of ordinary film can reduce the surface area of the film.

3. Cover the plastic film. The membrane is impervious to water, which can reduce the evaporation and irrigation times of the surface water, and achieve the purpose of reducing the humidity of the air in the shed.

4. ridge cultivation. The high ridge has a large surface area, receives more light during the day, and absorbs more air heat, so the temperature rises quickly, the soil moisture evaporates quickly, and the humidity is not easily high.

5. Reasonable watering. In the winter, when pouring vegetables, it should be done “five irrigations and five irrigations, five irrigations and five irrigations, no irrigation”. That is to say, there is no sunshine, no cloudy, no irrigation before watering, no watering after (noon before noon, no), no small irrigation (small irrigation, small irrigation), no cooling (in winter, the water temperature is very low, It should be preheated in the canopy and then irrigated when the water temperature is close to the ground temperature. There is no darkness (irrigation darkness), water, no water. At the same time, vigorously promote new irrigation techniques such as drip irrigation and flood irrigation.

6. dehumidifier dehumidification method, can be timed, and set the humidity value of the automatic dehumidifier, very convenient and practical, but in the plant shed, the dehumidifier is easy to be affected by environmental problems, so if you buy a dehumidifier, it is recommended to add anti-corrosion. This will extend the life of the dehumidifier and maximize the benefits!

7. ventilation and dehumidification. Ventilation is the most basic method of dehumidification in plastic greenhouses. In one day, the best time for ventilation and dehumidification is noon, because during this period, the humidity inside and outside the shed varies greatly, and the humidity is easier to discharge. Ventilation time should be extended as much as possible while maintaining temperature requirements. In addition, 2-3 days after watering the greenhouse, 1-2 days after fertilization (drugs), and rainy (snow) before and after sunset should pay special attention to strengthen ventilation and dehumidification.

8. cultivating loose soil. After the ground is watered, the furrow should be plowed in time to destroy the capillary of the surface soil and prevent the water in the lower soil from moving to the surface soil.

9. artificial moisture absorption. If the humidity in the shed is too high, you can sprinkle some straw, wheat straw, straw ash or fine dry soil between the rows, and stack moisture-absorbing materials such as quicklime in the free position in the shed to absorb the water.
