The focus of temperature management is to work well for cold protection and to control the temperature at a suitable growth temperature for peppers. The day's temperature management is divided into several periods. After the grass is uncovered in the morning, the temperature is rapidly increased and maintained at 25°C to 30°C. The temperature does not exceed 30°C without releasing the air. In the morning, the photosynthesis intensity of the pepper is high. After 1 pm, the respiration increased relatively. At this time, the emphasis was on the inhibition of respiration. With proper ventilation, the temperature was lowered and maintained at 20°C-23°C. The focus of the previous night's management was to promote the transport of photocontracts during the day. At this time, the pepper plants performed respiration and the suitable temperature for promoting the assimilate outflow was 18°C-20°C. By the middle of the night, the management will focus on suppressing respiration as much as possible, reducing the consumption of nutrients and controlling the temperature at around 15°C.
Humidity management Humidity is too high, which can cause various diseases of pepper to be high and must be dehumidified. The best way to dehumidify is by watering under the membrane. The time of watering is selected in the morning, which is conducive to the temperature rise and humidity removal. The method of dehumidification is that after watering, it does not release air, so that the temperature in the room rises rapidly, the water on the surface evaporates, the humidity of the air increases, and the air is quickly released after 1 hour for 10 minutes. The air outlet is large, the time is not long, and then it is closed. Vent outlet, repeat this operation again. After 2-3 times, the surface moisture can be basically eliminated.
