“香稻米”产地宿州市夹沟土壤和水质的分析

用EDTA络合滴定法、分光光度法、原子吸收法分光光度法测定宿州市夹沟土壤中钙、镁、铁、铜、锌、铅、镉、铬、砷、汞10种离子的含量,用高效毛细管电泳法测定水稻灌溉用呵泉水中钾、钠、钙、镁、钡、锶、锂7种离子的含量,经分析结果表明,土壤中的铅、镉、铬、砷、汞含量远低于宿州市土壤背景值,钙、镁、铁、铜、锌含量高于土壤背景值,这说明夹沟土壤基质优良,有利于水稻的生长;呵泉水中,除钠、镁离子低于普通水水样外,钾、钙、钡、锶、锂离子均高于普通水水样,呵泉水无污染且富含微量元素锶,泉水用于灌溉水稻可以增加香稻米的品质。

Study on Soil and Water Quality of Aromatic Rice Habitat in Jiagou of Suzhou City

The EDTA complexometric titration,the spectrophotometric method,the atomic absorption spectrophotometric method were used to measure the ion conternt of the calcium,the magnesium,hard,copper,the zinc,the lead,the cadmium,the chromium,the arsenic,the mercury in the soil of Jiagou in Suzhou.It is indicated that in the soil lead,the cadmium,the chromium,the arsenic,the mercury content were much lower than the Suzhou soil background value,the calcium,the magnesium,the iron,the copper,the zinc content are higher...
