| 摘 要： | 给出了慢速渗滤土地处理条件下土壤系统中硼的非稳态与稳态定义;建立了硼在土壤-植物系统中分布与输送的数学模型。论述了土地处理系统水力负荷,硼污染负荷、土壤理化性质、淋失率等因素对硼累积与迁移的影响。通过讨论硼的土壤溶液浓度同植物摄取的关系,提出了减少污水土地处理系统中硼对植物危害的途径。该模型可用于土地处理系统或灌溉系统硼的预测。

| Abstract: | The distribution and transportation of boron in land treatment system under slow rate condition were studied. A mathematic model was developed for describing the transportation process from unsteady to steady-state in the soil-plant system.
The effects of hydrologic loading, boron loading, physical and chemical properties of the soil on the accumulation and transportation of boron were discussed. The measures for inhibiting the absorption of boron by plant were suggested. |
