结合地质调查报告,通过典型样地调查及取样,对不同区域土壤、农作物含硒量进行测定分析。结果表明:青海省乐都县瞿昙镇、平安县小峡镇及平安县三合镇部分村镇土壤硒含量达到富硒标准,其中乐都县瞿昙镇洪庄村土壤硒含量最高,为0.724 mg/kg;乐都县瞿昙镇、碾伯镇、峰堆乡、雨润镇、高店镇部分村镇土壤硒含量达到足硒标准;平安县洪水泉乡、小峡镇、三合镇部分村镇土壤硒含量达到足硒标准,其中平安县三合镇西村土壤硒含量最高,为0.449 mg/kg;土壤含硒量最高的土壤类型为红土,土壤含硒量最高的土壤质地为壤土;部分村镇大蒜、娃娃菜、甘蓝、春小麦、青稞达到富硒标准;部分村镇马铃薯、玉米、马铃薯、胡萝卜、小麦、燕麦、油菜籽达到足硒标准;项目区接近60%的人群毛发硒含量处于足硒或富硒水平。
Based on the geological survey report, the selenium content of soils and crops in different regions was measured and analyzed through typical sample surveys and samplings. The results showed that selenium content in soil of Qu Tan town, Xiaoping town of Ping’an county and Sanhe town of Ping’an county reached a selenium-enriched standard. The selenium content of Hongzhuang village was highest in Qutan town of Ledu county, which was 0.724 mg / kg; Seduluo Town Qu Town, grind town, Fengdui Township, Yurun, Gaodian part of the town of soil selenium content of the soil to meet selenium standards; Ping County flood Springs, Xiaoxia, Sanhe Town, part of the village The selenium content of the soil reached the selenium standard. The selenium content of the soil in the west of Sanhe Town, Ping’an County was 0.449 mg / kg. The soil type with the highest selenium content was laterite. The soil with the highest selenium content was loam soil. Garlic, baby food, cabbage, spring wheat and barley reached the standard of selenium enrichment. Potatoes, corn, potatoes, carrots, wheat, oats and rapeseed reached the standard of selenium in some villages and towns. Selenium content in hair of nearly 60% Selenium level.
