对我国普遍采用的各种类型单屋面温室的结构研究表明,从透明后屋面进入的光对温室的光温性能有很大的影响.本研究测定结果是,后屋面透明的温室,地面水平光强度比对照增加0.60—26.31%; 白天气温和地温分别提高3.25℃和2.24℃;夜间气温差异不大,而地温有不同程度的提高;温室内果菜类蔬菜生长前期的最适温度的延续时间,每天平均比对照长1.7小时.并求得了温度、光强度与高度、跨度的回归方程.
The research on the structure of various types of single-roof greenhouses commonly used in our country shows that the light entering from the transparent roof has a great influence on the light and temperature performance of the greenhouse.The result of this study is that the back-roofed transparent greenhouse, The intensity increased by 0.60-26.31% compared with the control; the daytime temperature and the ground temperature increased by 3.25 ℃ and 2.24 ℃ respectively; the nighttime temperature difference was not big, but the ground temperature increased to some extent; Average daily 1.7 hours longer than the control, and obtained the temperature, light intensity and height, span regression equation.
