Abstract：According to common drip tape used low operating pressure of drip irrigation system, hydraulic performance of the different types of the emitters which are very popular on the market at present. The re-sults show that the relationship of emitter discharge and pressure under low operating pressure (2～8 m water) was different from that under conventional pressure(7～12 m water). Low operating pressure of the manufacturer's variation of emitters which compared with under operating pressure of the manufactur-er's variation of emitters trend to increase, because the manufacturer's variation of emitters which resul-ted from materials and manufacturing processes is more obvious.
