Temperature management. The main work is ventilation and cooling, but to prepare for cold and early frost prevention. Using the temperature cycle characteristics of pepper, the day's temperature management is divided into several periods. After the grass is uncovered in the morning, the temperature is increased rapidly, maintained at 25-30°C, and the temperature does not exceed 30°C. The photosynthesis intensity of the morning chili peppers high. After 13:00 in the afternoon, the respiration increased relatively. At this time, the focus was to suppress the respiration. By appropriate ventilation, the temperature was lowered and maintained at 20-23°C. The focus of the first half of the night was to promote the transport of photogenic compounds during the day. At this time the pepper plant respiration, and promote the appropriate temperature of the assimilate outbound is 18-20 °C. By the middle of the night, the management will focus on suppressing respiration and reducing nutrient consumption as much as possible, and the temperature will be around 15°C. For greenhouses with poor insulation in winter, the time for uncovering grasshoppers can be used to increase night and minimum temperatures. Humidity management. If the humidity is too high, “wet†phenomenon of the pepper leaves will occur and dehumidification must be performed. 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 cannot be long, and then it is closed. Vent outlet, repeat this operation again. After 2-3 times, the surface moisture can be basically eliminated.

It is the process of coating iron and steel with zinc, which alloys with the surface of the base metal when immersing the metal in a bath of molten zinc at a temperature of around 840 °F (449 °C). When exposed to the atmosphere, the pure zinc (Zn) reacts with oxygen (O2) to form zinc oxide (ZnO), which further reacts with carbon dioxide (CO2) to form zinc carbonate (ZnCO3), a usually dull grey, fairly strong material that protects the steel underneath from further corrosion in many circumstances. Galvanized steel is widely used in applications where corrosion resistance is needed without the cost of stainless steel, and is considered superior in terms of cost and life-cycle.
