文章通过对关中地区8种主要农作物及对应根系土进行硒含量调查,8种农作物可分为四类,即籽粒类、茎叶类、块茎类和果实类。结果表明,土壤硒含量在0.5264~0.6614 mg/kg之间,具体表现为籽粒类 >块根类 > 茎叶类 > 果实类,且均为富硒土壤;农作物硒含量相差较大,最高硒含量为小麦0.4290 mg/kg,最低硒含量为0.0106 mg/kg,总体呈现为小麦 > 大蒜 > 玉米 > 芹菜 > 菠菜 > 红薯 > 甜椒 > 圣女果。根据《富硒含量食品与相关产品硒含量标准》(DB61/T 556-2018)规定可知,小麦、大蒜、玉米、芹菜、菠菜、红薯均为富硒作物,而甜椒和圣女果则为含硒作物;农作物样品硒含量与对应土壤硒含量呈显著正相关关系。
The article investigates the selenium content of 8 main crops and corresponding root soils in Guan-zhong area. The 8 crops can be divided into four categories, namely grains, stems and leaves, tubers and fruits. The results showed that the soil selenium content was between 0.5264~0.6614 mg/kg, belonging to selenium-rich soils, and the specific manifestations were grains > roots > stems and leaves > fruits; the selenium content of crops varied greatly, and the highest selenium content was wheat 0.4290 mg/kg, the lowest selenium content is 0.0106 mg/kg, the overall appearance is wheat > garlic > corn > celery > spinach > sweet potato > sweet pepper > cherry tomatoes. According to the “Standard for Selenium Content in Foods and Related Products with Selenium Content” (DB61/T 556-2018), wheat, garlic, corn, celery, spinach, and sweet potatoes are all selenium-rich crops, while sweet peppers and cherry tomatoes are Selenium-containing crops; the selenium content of crop samples has a significant positive correlation with the corresponding soil selenium content.
