温室大棚内地层与微环境温度是影响农作物出产率的重要因素,为解决温室大棚由于太阳辐射导致的温度不平衡问题,提出太阳能辐射阵列管在温室大棚中的应用。通过在阵列管中添加水或相变材料,研究阵列管对地层与微环境温度变化的影响。通过对地层与微环境温度试验结果分析可知,通过布置阵列管可对温室大棚内微环境与地层深度10 cm处起到恒温作用,且可一定程度提升地层深度为30、50 cm处的温度,对构建良好的植被生长环境起到积极作用。
Abstract
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.
