摘要
滴灌水源中的悬浮固体物质会在毛管中沉淀并引起滴头堵塞 ,从毛管水力特征、泥沙运移沉淀和能量平衡的观点出发 ,研究了悬浮固体物质在毛管中的迁移规律 ,分析了影响悬浮固体物质在毛管中运移和滴头堵塞的主要因素 。
Suspended solids in water used for trickle irrigation contribute to sedimentation in laterals and plugging of emitters. From lateral hydraulic, solids transportation and energy conservation′s point of view, the patterns of suspended solids transport and deposit in trickle irrigation laterals are studied, the factors of influencing the suspended solids transportation and emitters plugging are analyzed. This will result in improved design and management of trickle irrigation systems. [
