Insulation and cold protection technology in greenhouses generally have the following:

Insulation and cold protection technology in greenhouses generally have the following:

1. Cover the endometrium

If the greenhouse is 8 meters wide, the gap between the inner and outer membranes should be more than 25 cm in order to achieve air insulation, thereby reducing air convection and heat loss.However, since a temperature difference is generated, water droplets are easily formed inside the inner membrane, which in turn causes an increase in humidity in the shed.

2. Cover non-woven fabric

Compared with the capping of the inner membrane, the humidity in the shed can be reduced, thereby reducing the occurrence of pests and diseases. In addition, its insulation effect is also very good, and easy to manage, but it should be noted that the non-woven fabric is best hung in the surrounding position of the shed.

3. Use some heating equipment

Such as heaters, etc., its power is 1000 watts, 1500 watts, 2000 watts and 2500 watts. Although it can effectively increase the temperature inside the shed, the price of the equipment is relatively high.

4. Smoked

For its raw materials, you can use red-burned briquettes and sawdust to avoid the appearance of open flames and other fires. In addition, it can be combined with a fumigant.

5. Spray warm water
The temperature of the water should be 25 °C - 28 °C, but it will increase the humidity of the air. Therefore, if the temperature is above a certain value after spraying warm water, then ventilation should be carried out so that the moisture can be removed.
