摘要

在富硒潮土中施加磷酸二氢钙和硫磺

进行室内模拟试验

分析了土壤中水溶态硒和交换态硒含量的变化。结果表明

在潮土中施加磷酸二氢钙和硫磺对土壤中的水溶态硒含量变化影响不显著

适量施加磷酸二氢钙可提高土壤中交换态硒含量

施加硫磺的提高作用稍弱;施加0.12%的磷酸二氢钙

或者施加0.12%磷酸二氢钙加0.011%硫磺的方式

能有效地提高潮土中交换态硒的含量。试验结果对合理利用含硒土壤资源

科学施肥

开发富硒农产品具有指导意义。

Abstract

Changes in the contents of aqueous and exchangeable selenium in Fluvo-aquic soil were studied by indoor simulated experiment.Calcium dihydrogen phosphate and sulphur were added to the soil.Experimental results showed that the variation of aqueous selenium content was not significant in the soil with the addition of calcium dihydrogen phosphate and sulphur.The proper addition of calcium dihydrogen phosphate increased exchangeable selenium content

but the addition of sulphur showed a weaker effect.The content of exchangeable selenium in soil increased effectively if 0.12% calcium dihydrogen phosphate was added

or 0.12% calcium dihydrogen phosphate and 0.011% sulphur were added.The results were significant of the utilization of selenium-rich soil resources and the development of selenium-rich food.
