| Abstract: | A field experiment was carried out for combining control of irrigation and drainage in paddy rice in Taishan city, Guangdong province. Based on experiment data, a mathematical model is developed to describe flow rate changes for various water dischargers under given work pressure and pipeline diameter and different water discharger's open situation. The operation parameters of the different water dischargers under different pipeline diameters and under different work pressure also are calculated and simulated. The simulated values coincide well with the practically measured values. |
