The ground layer and microenvironment temperature of greenhouses are important factors affecting the crop yield. In order to solve the temperature imbalance problem caused by solar radiation in greenhouses
the application of solar radiation array tubes in greenhouses was put forward. By adding water or phase change material into the array tubes
the influence of the array tubes on the temperature change of the formation and microenvironment is studied. The experimental group and the control group were established. In order to monitor the test results
the ground was divided into six areas
and temperature measuring points with different depths were arranged in each area
and temperature measuring points with different heights were arranged in the center of the greenhouse. Through the analysis of the test results of stratum and microenvironment temperature
it is known that by arranging array tubes
the temperature of the microenvironment in greenhouse and the stratum depth of 10 cm can be maintained
and the temperature of the stratum depth of 30 cm and 50 cm can be increased to some extent
which plays a positive role in creating a good vegetation growth environment.
