| 摘 要： | 土壤入渗参数是地面灌溉中制定灌溉制度、评价灌水质量的重要指标。针对现有估算方法存在计算工作量较大、精度不高的现状，根据田间实测资料，利用SIRMOD模型，对小麦畦灌条件下田间土壤入渗参数进行了估算。与用Maheshwari法计算结果较为接近，差异均在2.0%以内。根据估算的土壤入渗参数，应用SIRMOD模型进行了多组合灌溉模拟，在保证灌水质量较高的条件下，得出了在不同亏缺水量时的适宜灌水量和灌水流量，通过田间实例验证表明模拟效果较好。 |

| Abstract: | Infiltration parameter is one of the most important indexes in both irrigation schedule design and irrigation efficiency evaluation for surface irrigation. Most methods used currently to estimate the parameters have the disadvantages in low efficiency and precision. SIRMOD method was employed to estimate the infiltration parameters for border irrigation under the condition of wheat planting. The results showed that the errors of the infiltration rates were less than 2.0% calculated by Maheshwari and SIRMOD methods, respectively. Multi-irrigation alternatives were modeled by SIRMOD and the optimum irrigation quota and irrigation flow with high irrigation efficiency different water deficient conditions. The field experiments were carried out using the modeled results. The observed data from the field experiments verified the agreement with the modeled results. |
