Abstract: In order to efficiently use irrigation water and micro-spray irrigation facilities, the test was carried out on high efficient and saving cost micro-sprinkling irrigation method for the crop with narrow row spacing and close planting in Linfen of Shanxi Province. The method was as followed: The water diversion belts were perpendicular to the direction of crop planting; the water delivery pipes were erected perpendicular to the water diversion belts; the micro-spray irrigation facilities perpendicular to the water delivery pipes, which was fixed by the U type clip. After accomplishing current irrigation, the water diversion belts were moved from the field, the rest facilities were stored in the shelve area. The water diversion facilities were moved into the field to install after next crop sowed and the rest facilities were installed as the above method. The results showed that this method was more efficient in saving water and mid-late irrigation effect than the traditional method (micro-spray belt along the crop line) , and the cultivated land use efficiency increased by 16.5%, and the cost saved 525-600 Yuan per hectare for carrying, installing and dismantling each crop. The study provided the technical support for the large area application of this method.
