摘要
根据膜孔灌溉大田灌水试验资料 ,分析了膜孔灌溉特点和灌水技术要素对膜孔灌灌水定额的影响 ,研究了单宽流量与开孔率与膜孔灌灌水定额的关系。
Characteristics of film hole irrigation and effects of irrigation technological parameters on irrigating quota are analyzed, and the relationships among discharge per unit width, hole spacing and irrigation quota are studied in this paper, based on field experimental data. These results lay a foundation for further research on film hole irrigation.
