1 前言渗灌是一种新型的节水灌溉形式,具有节水、省工、投资少等优点,但却存在着容易堵塞等缺点,目前还没有成套的技术数据和完整的实践经验可以借鉴,尤其是关于渗灌管堵塞方面的研究和试验资料比较缺乏。笔者通过田间试验取得可靠的资料和经验,以此来研究分析渗灌管抗堵性能。2 试验区基本情况试验区位于三门峡市陕县宜村乡,属黄土台塬区,多年平
1 Introduction Infiltration irrigation is a new form of water-saving irrigation, with the advantages of saving water, labor, less investment, but there are shortcomings such as easy to plug, there is no complete set of technical data and complete practical experience can learn from, In particular, there is a paucity of research and experimental data on pipe plugging. The author obtains reliable data and experience through field experiments, in order to study and analyze the anti-blocking performance of the seepage irrigation pipe. 2 The basic situation of the pilot area The experimental area is located in Sanmenxia City, Shaanxi Province Yicun Township, is loess plateau area, many years of peace
