| 摘 要： | 为探索外遮阳网材料对温室内光环境的影响，借助热辐射的相关理论，在详细分析太阳辐射在温室内传播过程的基础上，建立了在外遮阳覆盖条件下连栋塑料温室内光环境的预测模型。通过对相同透射率、不同反射率外遮阳材料覆盖下模型温室内光照度的测试显示：模拟结果和实测值吻合较好，且遮阳网的反射率越高，温室内光照环境越好。

| Abstract: | In order to clarify how the physical properties of an outer-shading screen effect the solar radiation environment inside a greenhouse, a study, based on heat radiation theory, was undertaken. After making a detailed analysis of the transfer pathways of solar radiation inside the greenhouse, a model was developed for the multi-span plastic greenhouse equipped with outer shading screens. The experiment, which was conducted in a small-scale greenhouse, showed that when using different screen materials with the same transmittance but different reflectance, a greenhouse shaded with higher reflectance material has better illumination inside. The measured results are in close agreement with the simulated results. |
