交变电场在提高土壤水势中的作用

摘要:
电磁场对土壤作用的实验表明,交变电场不仅可以较大幅度的提高土壤水势,而且其作用对土壤结构没有明显影响,即土壤不会受到“破坏”或“污染”。这一发现对探索干旱半干旱地区作物用水问题,可能开辟了一个新途径。由实验还得出了土水势变化与外加交变电压的关系等实验规律。

Action of Alternative Electric Field to Increase Water Potential of Soil
Fu Zhidong Wei Qingfeng
Abstract:
Through experiments of the action of electromagnetic field to soil column, it is discovered that water potential of soil can be increased greatly by the action of alternative ' electric field, and some principles between outside electric field and the water potential of soil etc. are gained. The experiments also indicate that water potential of soil can return to its origenal value when the electric field is cancelled. These results show that the soil structure acted with alternative electric field has not been destroyed, and there is no'pollution'of soil to be found. And thus, this discovery presents a new way of using soil water in arid and semiarid areas.
Key words:  experiment of soil water, alternating current/alternative electric field,soil water potential
