摘  要：
为探索不同种植模式对晋北盐碱土水盐运移规律的影响,采用田间试验方法,设置空白对照、平作不覆膜、平作覆膜、起垄覆膜和全膜双垄沟5个处理,利用HYDRUS-1D/2D模型对不同种植模式下土壤水分和盐分运动规律进行数值模拟,分析了不同种植模式下水盐运动状态,并对比分析模拟结果与田间实测数据.结果表明,全膜双垄沟模式可有效提高土壤含水率,降低土壤电导率,缓解土壤盐分胁迫,为作物生长提供良好的水盐环境.HYDRUS-1D/2D模型对晋北盐碱土水盐运移规律的模拟结果可靠,能够为晋北地区盐碱土壤水盐管理提供科学依据.

摘  要：
To explore the effect of different cropping patterns on salt and water migration in saline alkali soil of northern Shanxi province, five treatments were set to simulate the movement of soil water and salt under different planting patterns by using HYDRUS-1D/2D model. The movement of water and salt under different planting patterns was analyzed, and simulated results were accordance with the measured data. The results showed that soil water content could be improved effectively and soil electrical conductivity was reduced by using double furrowwith mulching, high salt stress could be alleviated, a good water and salt environment for crop growth was provided. The HYDRUS-1D/2D model is reliable in simulating the water and salt transport law of saline-alkali soil in northern Shanxi, and the result can provide a scientific basis for water and salt management of saline-alkali soil.
