Vegetable sheds
1. Wind-for-air dehumidification
Ventilation is the most fundamental method of dehumidizing greenhouses. The vent must be carried out at low temperatures, otherwise the temperature in the shed will rise. Within one day, the best time for a ventilated humid outcome was at midnight, as the balconies varied widely and the humidity was more simple than intended. Other periods of time are to extend only through-the-wind time, subject to the containment temperature request. If the temperature drops too fast during venting, the vent is closed in real time to avoid the risk of sudden temperature landings for vegetables。
2. Acceptance of membrane cover
The membrane cover, which evaporates into the shed with additional surface water, is the main method of evaporating the atmosphere within the shed。
3. Wet control with dust and smoke
The admission of dust and fumes can avoid increased air moisture and control results due to spray。
4 - wetting in china
Sequestration of the soil plume avoids the rise of the mud plume to the surface and avoids small evaporation of the soil content。
5. Natural wetting
A layer of straw, wheat ... Straw, lime, or a layer of grass-wood ash shall be laid between rows, which shall not be validly adsorbed with water vapour or fog and reach the wet target。
6. Temperature/wetting
When temperature is lower, the temperature can be increased to lower relative humidity in the room and the demand for the temperature is satisfied with the vegetables。
7. Justice and water management
Watering is a secondary factor in increasing humidity in the shed. In winter and spring, clear ditches may be chosen or watered in separate strains, with sub-acceptable membranes covered. We need to keep a tight grip on the water. The water is properly ventilated and turpentine is applied in real time to reduce the humidity of the atmosphere。
8. Wetting with increased permeability
Increased permeability increases the temperature of the sheds, and the low temperature of the sheds increases the temperature of the atmosphere to a low level of relative humidity。
9. Accept the wetting screen
Antennas are set in the sheds, with the choice of warm materials that are wet and humid, such that the absence of swipes deters internal and external appearances and prevents dew from falling on the plant, thus reducing the humidity of the atmosphere。
During the summer season, vegetable pests and diseases in the sheds must be treated only with smoke or dust; if spray is administered, the number of treatments and the amount of fluids should be appropriately added to avoid excessive humidity in the sheds。
