通过对江汉平原富硒土壤分布范围内小麦、水稻等农作物和根系土壤调查取样分析,进一步证实了江汉平原富硒土壤的存在,并发现由富硒土壤种植生长的小麦、水稻为硒含量适宜的富硒农产品。农产品累积效应研究表明,江汉平原小麦、水稻对土壤中硒元素具有高富集性,有利于种植开发富硒小麦、水稻等优质农产品。江汉平原富硒土壤可生产富硒农产品的发现,对江汉平原富硒土壤资源开发利用具有重要的现实意义。
Through the investigation and analysis of the soils and soils of wheat and rice within the distribution range of the selenium-rich soil in the Jianghan Plain, the existence of the selenium-enriched soil in the Jianghan Plain was further confirmed. It was found that the wheat and rice grown from the selenium-enriched soil were suitable for selenium content Se-rich agricultural products. Accumulation effects of agricultural products showed that the Jianghan Plain wheat and rice have high enrichment of selenium in the soil, which is good for planting and developing high-quality selenium-enriched wheat and rice. The discovery of selenium-enriched soil in Jianghan Plain for production of selenium-enriched agricultural products is of great practical significance for the exploitation and utilization of selenium-rich soil resources in Jianghan Plain.
