Abstract

The invention discloses a method for producing selenium-rich ecological rice. The method comprises the following steps of: adding water into a selenium-rich organic fertilizer for diluting by 600 times to form selenium-rich organic fertilizer solution; soaking rice seeds by using a soaking medicament for 12-18 hours, soaking the seeds by using the selenium-rich organic fertilizer solution for one day, accelerating germination and sowing; during fertilizer application at the seedling stage of paddy rice, applying the selenium-rich organic fertilizer to a seedling bed in an amount of 20-50kg / 100m<2>; at the breaking stage and milk-ripe stage of the paddy rice, spraying a selenium-rich organic fertilizer which is diluted with water by 700 times onto the leaf surfaces of paddy rice once respectively; and harvesting ripened paddy rice. According to the selenium-rich rice prepared by the method, the content of selenium is 0.2mg / kg, and the content of zinc is 15mg / kg, so that the standard of superior selenium-rich rice is reached; and meanwhile, the self-made selenium-rich organic fertilizer is prepared by adopting a reasonable proportion and a reasonable preparation process, the synergetic effects of the element selenium and other elements such as zinc, silicon, ferrum, molybdenum, aluminum and the like are used fully, soil pollution can be prevented effectively, and the soil structure and quality are improved.

Description

technical field [0001] The invention relates to the field of selenium-enriched rice cultivation, in particular to a production method of selenium-enriched ecological rice. Background technique [0002] Selenium is one of the indispensable trace elements for human life. It can enhance the immune function of the human body, and has anti-cancer and anti-cancer effects. It can also prevent and treat diabetes and cardiovascular and cerebrovascular diseases. Selenium deficiency can also lead to the occurrence of various eye diseases. Selenium supplementation is the best measure to prevent cancer, but selenium is not easily absorbed by the human body when taken directly. The best selenium supplementation measure is to ingest selenium from food to achieve the purpose of selenium supplementation. It is a good solution to achieve the purpose of supplementing selenium by eating selenium-enriched rice. [0003] Rice is a non-selenium-accumulating plant, but it still has certain bioacc...
