Comparison study on the absorption ratios of molybdenum,boron and selenium by red soil

  • 摘要: 通过室内培育试验,研究了在室温和保湿条件下,红壤对施用不同浓度钼、硼、硒的吸附率随培育时间的动态变化.试验结果表明,红壤对钼的吸附率并不随施钼浓度(0、0.5、1.0、2.0、4.0 mg·kg-1)的提高而提高,以施钼1 mg·kg-1处理的吸附率最高;施用不同浓度钼后,红壤对钼的吸附率随培育时间的延长而表现出先降低后升高的趋势.红壤对硼的吸附率表现为随施硼浓度(0、1.0、3.0、5.0、7.0 mg·kg-1)的提高而逐步降低的趋势,以施硼1 mg·kg-1处理的吸附率最高;施用不同浓度硼后,红壤对硼的吸附率随培育时间的延长而表现出先升高后降低的趋势.施用不同浓度硒(0、0.5、1.0、1.5、2.0 mg·kg-1)后,红壤中有效态硒的含量随培育时间的延长而呈现出先降低后升高的趋势,而在整个培育期间,红壤对硒的吸附率始终保持在较高的水平上.
    Abstract: The dynamic change of absorption ratios of molybdenum,boron and selenium by red soil with culture time under indoor condition were studied. The results showed that the absorption ratio of molybdenum didn’t increase with the increasing concentration(0,0.5,1.0,2.0,4.0 mg·kg-1)of applied molybdenum. And the absorption ratio of molybdenum by red soil of applying 1 mg Mo·kg-1 soil reached the maximum. After applying different concentration of molybdenum, the absorption ratio of molybdenum decreased first and increased later with culture time. The absorption ratio of boron by red soil decrease gradually by the increasing concentration(0,1.0,3.0,5.0,7.0 mg·kg-1)of applied boron. And the absorption ratio of boron by red soil of applying 1 mg B·kg-1 soil reached the maximum. After applying different levels of boron, the absorption ratio of boron increased first and decreased later with culture time. After applying different concentration(0,0.5,1.0,1.5,2.0 mg·kg-1)of selenium, the available selenium content in red soil decreased first and increased later with culture time. The absorption ratio of selenium by red soil was keeping in a high level through the whole experiment period.
