- Abstract:
- Field experiments were conducted to investigate the influences of border dimensions and irrigation variables on the performance of water advance under straw mulch, irrigation efficiency and distribution uniformity (DU). The commercial software, namely SRFR406, was used to simulate the performance of water advance. The results showed that the code simulated the performance of water advance successfully. The border dimensions had influences to application efficiency, borders having 2～3 m wide, not more than 50 m long, inflow rate of unit width is from 6 L/ (m·s) to 8 L/ (m·s), and border slope is from 3‰ to 5‰ can get high application efficiency.
