摘　　要：用室外盆栽试验的方法,将土壤磁效应与生物磁效应相结合,以草甸土为供试土壤,油菜为供试作物,研究了盆栽条件下,磁处理土壤对油菜(BrassicanapusL.)油菜生物学产量和品质的影响,进一步探讨了磁场处理对土壤健康质量的改善作用。研究结果表明,磁场强度处理土壤不仅可提高盆栽条件下油菜的生物学产量,还促使其维生素C含量得以增加,而且油菜叶柄和叶片内的硝酸盐含量也降低,说明磁处理可以使土壤健康质量得到改善。200mT磁场强度是适于油菜生长的最佳磁处理参数。According to soil-magnetized and bio-magnetized effects, the improvement in the quality of rape (Brassica napus L.) and indication of soil-health quality by action of magnetization was testified using the pot-culture experiment. The result indicated that biological yield of rape was not only increased, but also vitamin C in rape plants was increased after the soil was treated by 200 mT of magnetization fields. However, the content of nitrate in rape tissues was decreased. It thus reflected that soil-health quality has been improved due to soil magnetization.
