Abstract

A sunken solar greenhouse has a good heat preservation environment. The influence of the general indoor temperature on the temperature of the roots was evaluated. A wireless sensor and U disk recorder were used to determine the indoor temperatures of a single section and multiple sections in a sunken solar greenhouse. Results showed that the rate of temperature change from in the vertical, horizontal and longitudinal sections in descending order at the opening moment and at the strong light moment. The temperatures in the single cross-section and multiple cross-sections were approximately equal during winter from 00:00 to 8:00 in the morning. These values can be used for calculating theoretically the heat loss in a greenhouse.

下沉式日光温室温室保温效果较好，室内温度会影响植物根区温度，利用无线传感器和U盘记录仪测定室内单截面和多截面的温度值，结果表明:在开启时刻和强光时刻，温度变化速率由大到小依次为垂直、水平和纵向；冬季00:00 ~ 8:00，单截面温度值与多截面温度值近似相等，可作为理论公式中计算温室热损失的依据。
