Problems solved by technology

These two kinds of organic selenium are also obtained by converting inorganic selenium through biotechnology, but the conversion rate is not high, and there are still residual inorganic selenium components in the product, which is still an unsafe selenium product

Abstract

The invention discloses a cultivation and planting method of selenium-enriched rice. The method includes the following steps that firstly, an inorganic selenium salt solution is prepared, wherein water and sodium selenite are weighed, the sodium selenite is fully dissolved in the water, and a sodium selenite diluent is obtained; secondly, a polysaccharide selenate substance rich in organic selenium is prepared, wherein seaweed in the sea serves as a carrier, the sodium selenite diluent is adsorbed by the seaweed, and by means of biological conversion of red algae, a polysaccharide substance in the seaweed and the sodium selenite are grafted into the polysaccharide selenate substance; thirdly, the polysaccharide selenate substance in the seaweed is purified, and the purified polysaccharide selenate substance is prepared into a polysaccharide selenate solution; fourthly, the prepared polysaccharide selenate solution is sprayed from the flowering stage of the rice to the filling stage. By means of the biological integration technology, the conversion rate of organic selenium in plants can be greatly increased; meanwhile, organic selenium polysaccharides in an organic selenium system are basically non-toxic organic selenium products, and the human body can not be harmed even after excessive eating.

Description

technical field [0001] The invention belongs to a method for cultivating and planting crops rich in certain trace elements, in particular to a method for cultivating and planting high-selenium-enriched rice. Background technique [0002] At present, there are many so-called high-selenium-enriched rices on the market. These rices all claim to have health benefits for many functions of the human body, such as: cardiovascular, liver, diabetes and anti-cancer effects. Moreover, the current selenium content of these rice is about 20ug-200ug / kg. The daily selenium supplement recommended by the Chinese National Center for Disease Control and Prevention and the Chinese Nutrition Society is 50-100ug / day. However, supplementing selenium through rice currently on the market cannot meet the daily needs of the human body. This is mainly due to the high price of selenium-enriched agricultural products and the low selenium content. However, the data set by the current national standard ...
