摘要/Abstract

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)幼苗硝酸还原酶活性、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酶活性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.

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 mTtreatment.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.
