微咸水滴灌条件下水肥一体化过程可能加剧灌水器堵塞的发生。【目的】评估氮磷肥协同施入对微咸水滴灌系统灌水器堵塞的影响。【方法】以灌水器类型、灌溉水电导率和氮磷肥协同施入模式为研究对象，灌水器类型选取内镶贴片式灌水器（E1）和单翼迷宫式灌水器（E2）；灌溉水质按照电导率设置3个水平，分别为2（S2）、4（S4）和6 dS/m（S6），另外设置地下水（G）（电导率约0.5 dS/m）作为对照（CK）；氮磷协同施入模式设置磷酸一铵-尿素（MU）、磷酸一铵-硫酸铵（MA）、磷酸二铵-尿素（DU）、磷酸二铵-硫酸铵（DA）4种，测定了灌水器流量、灌水器堵塞物质干质量及堵塞物质成分。【结果】滴灌氮磷协同施入条件，系统运行96 h时内镶贴片式灌水器平均相对流量均值较单翼迷宫式灌水器高19%，内镶贴片式灌水器...
