本试验通过室内培养方法,研究了磁场处理后根瘤菌USDA110(慢生型)和USDA191(快生型)的数量和生长速度的变化.结果表明:磁场对根瘤菌菌落的生长有影响,所有处理均起正效应,但磁场强度和磁处理时间对其影响的效果不同.磁场强度表现为 300 mT效果最显著;磁处理时间以5 min效果最显著.经磁场处理后,根瘤菌的生长速度加快,世代时间缩短.

The effects of magnetic treatment on amount and growth rate of slow-growing rhizobium(USDA110)and fast-growing rhizobium(USDA191)by incubation experiments were studied. The results showed that magnetic field had the effects on the growth of rhizobium strains, and all the treatments had positive effects, but magnetic field intensity and treatment time had different effects. The effects of magnetic field intensity and exposure time were different. In magnetic field intensity ,300 mT treatments had the most significant effect. In exposure time, 5 min treatment had the most significant effect and the growth rate of rhizobium was accelerated and generation time was shortened under magnetic treatment after the magnetic treatment.
