摘    要:用室外盆栽方法,将土壤磁效应与生物磁效应相结合,研究磁处理土壤对油菜(Brassica napus)幼苗硝酸还原配活性、可溶性糖含量、根系活力以及生物量的影响.结果表明,200mT磁处理土壤可提高油菜幼苗硝酸还原配活性10.76%,300mT和100mT处理均使可溶性糖含量增加11.05%以上,根系活力增加26.40%.生物量增加,地上部鲜重以300mT处理最大,比对照增加13.28%,地下部的鲜重以200mT处理最大,比对照增加13.17%,根冠比降低10.00%,说明土壤健康质量得到了改善。

关 键 词:磁化土壤  油菜  生理生化指标  土壤健康质量

Abstract:Nitrate reductase, peroxidase, water soluble sugars, root vitality and total biomass of Brassica napus seedlings were investigated with soil after magnetization treatment. The results showed that nitrate reductase activity was increased by 10.76% after 200 mT treatment.The contents of water soluble sugars were increased by 11.05% and root vitality by 26.40 % for 300 and 100 mT treatments, respectively. Total biomass also showed a trend of increase as the magnetization increased. The highest biomass of the above ground parts was achieved at 300mT, which was 13.28% higher than that of control. In addition, total biomass of below ground parts was the highest at 200mT, which was 13.17% higher than that of control,and the ratio of below ground to above ground parts decreased by 10.00%, suggesting that the overall environmental quality of the soil was improved significantly.
Keywords:Magnetized soil    Brassica napus    Physiological and biochemical index  Soil  health quality
