摘    要:抗旱灌水播种是解决春旱播种的一种有效形式,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:Drought -defying sowing is a kind of effective form in which a kind of settlement spring drought seeds.The soil moisture movement under this way was regarded as the two-dimentional moisture movement on the cross section of ditch in the article. The mathematics model was set up according to difference between the beginning and boundary condition. The value range in technical parameters was drawn with the numerical eomputation method, including a kind of furrow depth, irrigating volume, initial moisture content of soil.
Keywords:Numerical computation  Drought-defying sowing  Furrow depth  lrrigating volume  Initial moisture content of soil
