|Analysis of Temperature and Humidity in the Rain-shelter Cultivation in Southern China
Changde Agriculture and Forestry Science Academy
|This paper analyzed the temperature and humidity of the rain-shelter and the environmental change characteristics under typical weather using the ZigWSN internet of things information service platform equipment. The results showed that the average daily temperature difference in the rain-shelter cultivation could reach 21.1℃, and the average temperature was 6.4~9.4% higher than that in the open field. In typical weather, the change of temperature inside and outside the rain-shelter in the clear days was "V"-shaped, while the humidity in the clear days was "inverted V"-shaped. The temperature extreme inside the rain-shelter reached its peak value 2 hours earlier than outside the rain-shelter, which had a guiding function on agricultural production.
