Production method of green selenium-rich nutritional rice

Abstract

The invention provides a production method of green selenium-rich nutritional rice, and relates to the technical field of rice production, and the production method comprises the following steps: S1, selecting a land parcel which is flat in terrain, has irrigation and drainage openings, is convenient for irrigation and drainage, and has no garbage pollution as a seedbed; s2, performing comprehensive weeding on the seedbed, ploughing the land, making furrows in the north-south direction, performing grass sealing treatment on furrow surfaces and drainage ditches, and uniformly spraying on the earth surface; s3, preparing a biomass selenium-containing fertilizer, and adjusting the acidity of seedbed soil; according to the method, a means of combining multiple selenium increasing is included, a biomass environment-friendly recycled material is adopted for increasing selenium and fertility of soil, a drying and selenium-containing soaking means is adopted, seeds are subjected to activated adaptation and partial absorption on selenium elements, seed germination is promoted, then in three stages of rice growth, selenium fertilizer is sprayed for three times, and the selenium fertilizer is sprayed for three times; the selenium can be fully absorbed by stems, leaves, flowers and fruits, and verification shows that the selenium content of the rice produced by the method is 150-185 mu g / kg.

Description

technical field [0001] The invention relates to the technical field of rice production, in particular to a production method of green selenium-enriched nutritional rice. Background technique [0002] Selenium was discovered in 1817, and was recognized by the World Health Organization in 1973 as "an essential trace element for human and animal life and vitality". More than 40 countries and regions in the world are deficient in selenium or low in selenium. In my country, 72% of the regions have a third of them. The second population lives in areas with low selenium or selenium deficiency. Selenium is closely related to human vitality. Selenium deficiency can lead to a high incidence of various diseases in the human body, such as cardiovascular and cerebrovascular diseases, hypertension, diabetes, Kashin-Beck disease, Parkinson's disease, There are more than 40 kinds of diseases such as cancer. Therefore, the World Health Organization recommends that the human body is supplemente...

Problems solved by technology

[0003] People mainly rely on planting rice to produce rice to supplement selenium, but the selenium content in the soil is very low, which cannot meet the needs of human health. In the prior art, from the process flow, technical operation to implementation, generally the means of applying selenium fertilizer on the surface , but the absorption efficiency of crops is not high, so that the selenium content of rice is insufficient, and the breeding mode is single. Therefore, the present invention proposes a production method of green selenium-enriched nutritional rice to solve the problems existing in the prior art
