Abstract
[ Objective] To research the selenium content and resource distribution of cultivated land in Lichuan City of Hubei Province, and to provide scientific references for the development of selenium enrichmentindustry and the selenium enrichment agricultural products. [ Meth-od] With natural plot of household responsible field as the sampling unit, we detected the total selenium content in 621 soil samples of cultivat-ed land in Lichuan City, and analyzed the resource distribution of selenium. [ Result] The total selenium content in cultivated soil of Lichuan City was 0. 011-6. 121 mg/kg;the mean value was 0. 439 mg/kg, which was at a level of selenium enrichment. Selenium content in cultivat-ed soil had certain correlation with the organic matter in soil and the correlation coefficient was 0. 287 8. But it had no significant correlation with soil pH. Selenium-enrichment cultivated soil showed a “y”-type distribution. Wendou, Zhonglu and Shaxi were sturdy “y” type, which extended from southwest to northeast and northwest. Sampling sites with more than 0. 900 mg/kg selenium content in cultivated land were mainly concentrated in Wendou and Zhonglu belt, Qiyue mountain range ( containing Fubao Mountain) , Hanchi mountain range and Mashan mountain range. Selenium content in cultivated land had close correlation with coal. The four regions having relatively high selenium content all had coal mineral resources. Areas lacking of selenium were mainly distributed in Boyang Town and Jiannan and Moudao Towns in west Qiyue Mountain. [ Conclusion] Selenium content and distribution law in Lichuan City are preliminarily found out.关键词
