黑龙江省松嫩平原南部土壤硒元素的有效性与生态效应
Effectiveness and Ecological Effects of Soil Selenium in Southern of Songnen Plain of Heilongjiang Province
摘要
Abstract
Based on the research project of comprehensive evaluation for agricultural geological survey in south‐ern of Songnen Plain in Heilongjiang Province ,taking 1∶250 000 target geochemical survey area for the study of southern of Songnen Plain as research object ,the area about 8 .29 km2 ,collecting surface soil ,deep soil ,typical crops (maize ,rice ,soybean) and the corresponding root zone soil samples ,selenium element test was analyzed to identify geochemical characteristics of selenium in study area ,its soil effectiveness was described ,the geo‐chemical and ecological effects of selenium were comprehensively evaluated .The results showed that the sele‐nium content of surface soils in southern of Songnen Plain was 0 .204 mg·kg‐1 ,reached a moderate level ,it was low selenium zonation .Average selenium content of soybean was higher ,reflecting its utilization degree was higher .Average selenium content of maize was the lowest ,reflecting its utilization degree was poor .The sele‐nium intake of resident in southern of Songnen Plain was very low level ,selenium intake of 93% of residents was in the following security level ,that of approximately 53 .5% were lack .关键词
