| 摘 要： | 抗旱灌水播种是一种解决春旱播种的有效形式，把此方式下的土壤水分运动看成是沿种沟方向垂直剖面上的二维水分运动，根据不同的初边值条件建立了数学模型，用数值计算方法得出了种沟深度、灌水量、土壤初始含水率等技术参数的取值范围。 |
| 关 键 词： | 数值计算 抗旱灌水播种 种沟深度 灌水量 土壤初始含水率 |

| Abstract: | Anti-drought irrigation sowing technology is an effective method to solve the problem of sowing under spring drought. The movement of soil water under this method was regarded as two-dimension movement on the vertical section along furrow, and the mathematic model was set up based on various initial and boundary conditions in this paper. Also, the value range of some technical parameters, such as furrow depth, irrigation quantity and initial soil moisture, was got through numerical calculation. |
| Keywords: | numerical calculation anti-drought irrigation and sowing furrow depth Irrigation quantity initial soil moisture |
