Abstract
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.
