The advantages of micro-sprinkling irrigation method are moving easily , low investment, simple structure and extensive adaptability. After irrigating 200～400m³/ha, soil water content will be increased quickly. The suitable irrigation times are heading stage, jointing stage and turning greenstage. Between irrigation 200～400m³/ha, wheat yield increasement depends on the increasement of irrigation. Under film mulching , after irrigating ,wheat yield increased by 25.0%～90.4% compared with no irrigating. It is 22.5%～50.2% higher than no-irrigating under wheat farmland of no-film mulching. Micro-sprinkling irrigating method is practical and worth being extended.
