紫阳高硒土对不同品种辣椒含硒量的影响

Influence of Ziyang High Selenium Soil on Selenium Content of Different Pepper Varieties

以紫阳高硒土及当地栽培的4个辣椒品种为试材，研究了不同辣椒品种对硒的吸收、转化及硒对辣椒产量的影响。结果表明：4个辣椒品种硒的吸收能力为“巨无霸”〉“新丰”〉“洛-318”〉“超越清”，含硒量均表现为根〉叶〉茎〉果实；施硒对辣椒的增产幅度为29．7％～43．4％；4个辣椒品种的有机硒转化率均达到98％。

Taking four pepper varieties that cultivated in local and Ziyang lfigh selenium soil as materials,the absorption and transformation of different pepper varieties on selenium and selenium effect on pepper production were studied. The results showed that selenium absorption capacity of four pepper varieties was ＇Juwuba＇〉 ＇Xinfeng＇〉＇Luo-318＇〉 ＇Chaoyueqing＇ ,selenium content were characterized by the root〉leaf〉stem〉fruit. Selenium to pepper yield increased range of 29. 7%- 43. 4%. Four pepper varieties of organic selenium conversion rate achieved above 98%.
