巴东县野三关镇土壤及大蒜硒含量调查

Investigation of selenium content in soil and garlic in Yesanguan town,Badong county

对巴东县野三关镇12个采样点进行调查,研究大蒜(Allium sativum L.)样品的土壤及其大蒜各部位的富硒性。结果表明,12个采样点的土壤、蒜瓣、蒜薹、蒜叶的硒含量分别为0.083~2.676 mg/kg、0.054~0.589 mg/kg、0.038~0.257 mg/kg、0.033~0.152 mg/kg;不同土壤采样点,大蒜的蒜瓣、蒜薹、蒜叶硒含量均有差异;每个处理的蒜瓣对硒的富集性最强,大蒜各部位对硒的富集性强弱表现为蒜瓣>蒜薹>蒜叶。

The selenium enrichment of soil and garlic(Allium sativum L.)samples were investigated at 12 sampling sites in Yesanguan town,Badong county.The results showed that the selenium content of soil,garlic clove,garlic bolt and garlic leaf at the 12 sampling sites was 0.083~2.676,0.054~0.589,0.038~0.257 and 0.033~0.152 mg/kg,respectively.The selenium content of garlic cloves,bolls and leaves was different in different soil sampling points.The enrichment of selenium in each garlic clove was the strongest,and the enrichment of selenium in each part of garlic was shown as the garlic clove>garlic bolt>garlic leaf.
