摘  要:
提出了一种新的物理研究土壤及杀灭地下害虫的方法—高压脉冲电场杀虫,避免了常规大面积毒土对环境的污染。同时,介绍了一种易于实现频率、占空比、电流、电压等参数可调的高压脉冲发生及处理实验装置。通过此高压装置对实验样品土壤和害虫在实验处理室放电,研究高压脉冲电在土壤中的传播特性,并确定在什么样的条件下,高压脉冲电场对土壤中的地下害虫杀伤效果最好,同时又避免对益虫和植物的损伤。

摘  要:
This paper brings forward one physical method to kill underground pests and to study soil property---using high voltage pulse electric field generator, it avoids large scale of poisoned soil pollution. One high voltage pulse electric field generator experimental device is showed, it can adjust frequency, the rate of raise-time and fall-time, electrical current, electrical voltage etc. We could know the soil property by measuring these parameters while the current is getting across the soil. Moreover, we could find out the best conditions, the best parameters’ value after a lot of experiments, and it can not hurt beneficial insects and plants in these conditions.
