摘　　要：在能源危机的冲击下，节能已成为广大喷灌工作者共同关心的问题。降低喷灌系统工作压力是节能的主要方法之一，而喷头的工作压力与喷灌系统工作压力紧密相关。本文提出了固定式喷灌系统喷头经济压力的概念及其确定方法，并将此法运用到实例中。在选择经济、合理的喷头及其经济工作压力方面做了有意义的探讨。Enegy-saving is a Problem concerned by all sprinkler irrigation dcsigncrs beeause of the shock of energy crisis. Reducing the operating pressure of sprinkler system is one of the major energy -saving methods. And the operating Procure of sprinklcr head is concetncd with the operating prcourc of sprinkler system closely. This poper puts forward a concept of sprinkler economic pressure forpermanent system and its determination method. And the method has been used in an example. Ameaningful probe of selecting economic and rational sprinkler head and its economic Operating pressure hag been made.
