| 摘要: |
| 【目的】通过对温室内光照理论的分析，提出一种适用于高性能采光温室的可变采光倾角温室，并对其温光性能进行了研究。【方法】试验测定了位于西北农林科技大学园艺学院教学试验基地内的试验温室，并选取2010年冬季典型晴天和典型阴天的试验数据，分析研究了可变采光倾角日光温室与固定采光倾角日光温室内光照度与温度的差别。【结果】本试验条件下，与固定采光倾角日光温室相比，典型阴天时可变采光倾角日光温室内平均光照度提高了22.27%，平均温度提高了2.9 ℃；典型晴天时可变采光倾角日光温室内的平均光照度提高了29.00%，平均温度提高了4.3 ℃。【结论】与普通固定采光倾角温室相比，可变采光倾角温室内的平均光照度和平均温度均明显提高。 |

| Abstract: |
| 【Objective】A solar greenhouse with variable incidence angle was proposed based on experiment comparison and lighting analysis and its properties were investigated.【Method】The experiment was carried out at the experiment station of the College of Horticulture,Northwest A&F University during the winter of 2010.Technical performance of lighting and structure was discussed and compared theoretically.【Result】Under experimental condition of this study,the average lighting performance and mean indoor temperature in typical cloudy day increased by 22.27% and 2.9 ℃,respectively.The average lighting performance and mean indoor temperature in typical sunny day increased by 29.00% and 4.3 ℃,respectively.【Conclusion】The solar-greenhouse with variable incidence angle was more efficient in utilization of solar energy and raising temperature. |
