| Abstract: |
| Irrigation on film hole is a water saving method in both agronomic and irrigating aspects,but it is still imperfect in the technical factors.Based on the technique applying actuality,the orthogonal test project with four factors(including film hole diameter,film hole rate,flux per unit width and ground slope) and three levels was conducted.The results indicated that the optimal technical combination for the moderate infiltration soil area being suitable to film mulch on ridges was: hole diameter 5cm,film hole rate 3%,flux per unit width 3 L/(s.m) and ground slope 2‰. |
