Daily Management Of Greenhouse

The management of greenhouses has the following contents, regular ventilation and ventilation: as we said earlier, wetter greenhouses are mainly caused by their sealing, so proper ventilation and ventilation is a good way to reduce humidity. However, ventilation is not always possible and must be performed when the outdoor temperature is relatively high, otherwise the indoor temperature will drop. When ventilating, the temperature drops too fast, close the vent in time to prevent the sudden drop in temperature from causing harm to crops

Improve light transmittance: Increasing light transmittance can increase room temperature. After the room temperature rises, ventilation is often carried out to achieve the purpose of dehumidification. It can not only meet the temperature requirements of vegetables, but also reduce the relative humidity of the air. When the plant growth resistance, the temperature rise of the nozzle closed shed is about 30 ℃, and then the ventilation is affected with damp. After 3~4h, when the humidity of the shed is less than 25 ℃, the humidity in the shed can be repeated. Water is the main factor leading to the increase of indoor humidity. How to sprinkle water has become an important measure to control humidity. In winter and spring, sunny ditch water or water distributor can be used for production, and undercover irrigation can be selected for mulching. Sprinkling should be strictly controlled to prevent excessive indoor humidity. After each sprinkling, appropriate air release and timely loosening of the hoe can not only reduce soil moisture, but also reduce air humidity.

By cutting off the soil capillary, prevent the capillary moisture from rising to the surface layer, prevent the transpiration of a large amount of soil moisture. Data such as straw, wheat straw, quicklime, etc. can be used to adsorb steam or mist between rows to achieve the purpose of dehumidification.
