富硒蚯蚓的培养及其硒富集作用研究
The Cultivation and Selenium Enrichment of Selenium Enriched Earthworm
摘要
Abstract
As a bio-carrier, Eisenia fetida was fed with cow dung that added with sodium selenite in order to transfer inorganic selenium(Se) into organic selenium. Targeting on survival rate and selenium content, the effects of five Se concentrations(0, 20, 40, 60, 80, 100 mg·kg-1) and four cultivation periods(15, 30, 45, 60 d)on earthworm growth and Se contents were investigated. The cultivation method with high sur-vival rate, high Se content of earthworm and short breeding time would be screened out. The experimental results showed that the earthworm survival rate decreased and the Se content in earthworm increased with the increase of Se application and the extension of breeding time. The most optimum method was screened out when the Se concentration was 80 mg·kg-1 and the cultivation period was 45 days, Se content in earth-worm was up to 33.25 mg·kg-1.关键词
