针对温棚膜面集雨回用的水文及技术条件作了阐述,重点分析了回用中集雨量和温棚作物需水量的数据,通过建立集雨量与需水量耦合模型和相关分析,表明温棚膜面集水量与作物需水量耦合程度高。提出了发展温棚膜面集雨回用研究的关键技术问题和研究展望。
Based on the analysis of the hydrological and technical conditions of rainwater harvesting on the surface of greenhouse, this paper mainly analyzes the data of the rainfall collected and the water demand of greenhouse crops. By establishing the coupled model of rainfall and water demand and the correlation analysis, The membrane surface water harvesting and crop water demand coupling degree is high. The key technical issues and research prospects of the research on the development of greenhouse film rainwater reuse were put forward.
