Study on Soil Temperature Characteristics and Its Variation in Double-roof Greenhouse
To clarify the characteristics and variation patterns of soil temperature in a double roof greenhouse,the soil temperature of the 5cm,10cm,and 15cm deep soil layers inside and outside the double roof greenhouse was measured,and the soil temperature under different weather conditions was compared and analyzed.The results show that there is a positive correlation between the changes in soil temperature inside the greenhouse and the changes in external temperature.The temperature changes of soil at different depths are different,and the temperature of each layer of soil is lower in rainy weather conditions than in non rainy weather conditions(sunny,cloudy,and hazy).The temperature changes of each layer of soil are basically the same in different weather conditions,and there are obvious seasonal changes in soil temperature inside the greenhouse.The temperature changes of soil in different directions inside the greenhouse are basically the same.
