摘要：

The most serious problem in trickle irrigation is clogging of emitters or applicators. Recommendations and guidelines are presented for preventive maintenance which include water filtration, chemical treatment, pipeline flushing, and field inspection. A suitable type, size, and capacity of a filtration unit is required. Chemical treatment should be considered in terms of theory and field research on the reclamation and prevention of emitter clogging. Proper procedures for the flushing and field inspection of trickle irrigation systems are also essential. Because water quality is of primary importance in the design and operation of this maintenance program, a tentative water-classification system was developed to establish criteria by evaluating the clogging potential of a trickle irrigation water source. © 1979.
