Abstract Emitter clogging is one of the most important limiting factors affecting the promotion of drip irrigation. To examine the impact of the irrigation time on the lateral environment and to develop an optimal way to mitigate the emitter clogging risk, 4 different irrigation times (3, 7, 10 and 30 times) were examined with each irrigation period lasting 2 daily hours. Then, the lateral inner environment was studied from the perspectives of the mass, particle size composition, mineral composition, microbial content of the sediment in the lateral (includes sediment deposited in and adhered to the lateral, DS and AS, respectively). The index of the emitter clogging risk was used to indicate the emitter clogging level of the drip irrigation system. The results indicated that emitter clogging risk (Rec) was significantly correlated with the DS mass, AS mass, rate of change of the AS mass and fractal dimension (p

不同灌溉时间的横向内部环境变化及其对滴头堵塞风险的影响

摘要 滴头堵塞是影响滴灌推广的重要限制因素之一。为了检查灌溉时间对横向环境的影响并制定减轻排放器堵塞风险的最佳方法，检查了 4 种不同的灌溉时间（3、7、10 和 30 次），每个灌溉周期持续每天 2 小时。然后，从侧向沉积物的质量、粒度组成、矿物组成、微生物含量（包括沉积和附着在侧向的沉积物，DS和AS）等角度研究了侧向内部环境。滴头堵塞风险指数用于指示滴灌系统滴头堵塞程度。结果表明，发射器堵塞风险 (Rec) 与 DS 质量显着相关，
