| 摘 要： | 通过试验研究沟灌的二维入渗特性,研究结果表明:灌水沟断面尺寸、土壤初始含水率及土壤导水率对沟灌的入渗特性均有不同影响。灌水沟中水深小、沟底导水率的减小、土壤初始含水率增大都有利于灌水沟的水平侧向入渗,同时可相应减小垂向入渗,而灌水沟底宽不影响沟的侧向入渗,只影响垂向入渗,底宽减小时,垂向入渗减小。

| Abstract: | A series of experiments about two-dimensional infiltration characteristics for furrow irrigation were carried out in laboratory. The experiment results showed that low water level, reducing hydraulic conductivity in a furrow, increasing initial soil moisture content can increase lateral infiltration depth of irrigation furrow while decrease vertical infiltration depth. But furrow's bottom width can effect vertical infiltration only. When the bottom width is reduced, the vertical infiltration depth decreased. |
