| Abstract: | Through irrigation experimental study on drip system with multiple minor-caliber pipe, relation on flow and pressure head is evaluated , and the comprehensive performance index of emitter is analyzed and evaluated. Data shows that emitter manufacture deviation is less than 5% and the level is superior under nominal working pressure. Irrigation uniformity of the emitters is more than 95% and the uniformity is good. Water head loss is 3% and the loss ratio is small. So multiple minor-caliber pipe is suitable for greenhouse irrigation. |
