摘要
采用不同场强磁场处理草甸土,研究磁处理对油菜生长及磷素吸收的影响。结果表明:磁处理草甸土种植油菜,苗期的鲜重、干重以100 mT场强处理效果较好,成熟期以400 mT场强处理效果较好。油菜苗期植株磷素吸收以低场强处理效果较好,成熟期以高场强处理效果较好。磁处理引起磷素有效性的提高是油菜植株磷素含量增加的关键因素之一。
Effects of different magnetic treatment meadow soil on growth and phosphorus absorption of rape were discussed. The results showed growth and phosphorus absorption of rape seedling were better in low magnetic treatment soil, and in high magnetic treatment they were more evident in harvest period. One of the crucial factors in increasing phosphorus absorption of rape is the increase of phosphorus availability resulted from magnetic treatment.
