SELENIUM-RICH VEGETABLE SEEDLING, CULTIVATING METHOD THEREOF AND ORGANIC-SELENIUM-RICH VEGETABLE YIELDED WITH THE SAME

摘要

A selenium-rich vegetable seedling, cultivating method thereof and organic-selenium-rich vegetable yielded with the same are provided. The selenium-rich vegetable seedling has a total selenium content of 18～1620µg per plant when transplanted. The method includes a step that nano-selenium plant nutrient is added into the soil or field during raising vegetable seedling to cultivate the selenium-rich vegetable seedling according to a vegetable raising seedling method. The organic-selenium-rich vegetable has a selenium content of 10～300µg/kg, wherein the content of organic selenium is no less than 80％. The vegetable is rich in selenium and the whole vegetable content is unified. The method increases the proportion of organic selenium, solves the stability problem of the selenium content of vegetables growing in different batches in the prior art and realizes standardization and scale production.
