摘　　要：为提高温室中太阳光的利用率,笔者通过对日光温室结构、外界环境条件和室内植物对日光温室光环境的影响相关的文献资料进行归纳总结,明确了日光温室光照环境问题的复杂性。首先,温室本身的结构对温室内光辐射影响较大,需因地制宜合理设计;其次,外界的自然环境对温室内光辐射亦有较大影响,雾霾阴天等自然环境会减弱温室内的光辐射,不利于温室植物的生长;此外,室内植物增加了温室内光分布的复杂性,植株垂直高度上,由上及下,光辐射呈现下降趋势。因此,日光温室建造者和经营者应充分考虑上述多重影响因素,科学规划、合理利用、巧妙规避风险,以提高收益。In order to improve the utilization rate of sunlight in greenhouse,the author summarized the literature about the structure of greenhouse,the external environmental conditions and the impact of indoor plants on the light environment of solar greenhouse,and made clear the complexity of the sunlight environment in the greenhouse.Firstly,the structure of the greenhouse itself has a great impact on the light radiation in the greenhouse,so it needs to be designed reasonably according to local conditions.Secondly,the external environment should be considered.In addition,indoor plants increase the complexity of light distribution in greenhouse,and the light radiation presents a downward trend from top to bottom in vertical height of plants.Therefore,solar greenhouse builders and operators should fully consider the above multiple factors,scientific planning,rational use,clever risk aversion,in order to improve the income.
