Nutrition fortification rice rich in organic selenium, zinc and chromium and production method thereof

Abstract

The invention discloses a fortified rice which is rich in organic selenium, zinc and chromium and a production method thereof; the fortified rice is produced by mixing and matching of selenium-rich rice which contains 0.3 to 0.5 mg / kg of selenium, zinc-rich rice which contains 8 to 10mg / kg of zinc and chromium-rich rice which contains 1 to 2mg / kg of chromium; the production method comprises the following steps: in the grain-filling stage of the paddy rice, selenium solution, zinc solution, and chromium solution are sprayed in different fields respectively so that nutrients and trace elements enter into the body of paddy rice directly to be involved in the metabolism and organic synthesis of the paddy rice, enhance the intensity of grain filling, promote the prematurity of the rice and enrich the content of selenium, zinc and chromium in the grains, wherein, the selenium solution is prepared by the following ingredients by weight: 1 percent of selenium dioxide, 1.5 percent of methionine, 5 percent of fulvic acid and 92.5 percent of water, which are stirred and dissolved; the zinc solution is prepared by the following ingredients by weight: 20 percent of zinc sulfate with 7 water of crystallization, 1.5 percent of methionine, 5 percent of fulvic acid and 73.5 percent of water, which are stirred and dissolved; and the chromium solution is prepared by the following ingredients by weight: 15 percent of organic trivalent chromium, 3 percent of fulvic acid and 82 percent of water, which are stirred and dissolved. The paddy rice obtained by the method matures 5 to 7 days averagely and the yield of the paddy rice is increased by 7 to 10 percent per mu, or per 667 square meters.

Description

technical field [0001] The invention relates to a nutritional rice rich in various trace elements such as selenium, zinc and chromium and a production method thereof. Background technique [0002] Selenium, zinc, and chromium are essential trace elements for the human body. The lack of it will cause functional or organic changes, and various diseases will occur. Sufficient intake of three elements of selenium, zinc and chromium every day can improve human immunity and delay aging. At present, there are only reports on selenium-enriched and zinc-enriched rice, but no report on chromium-enriched rice. [0003] The production methods of nutrient-enhanced rice rich in selenium and zinc trace elements mainly include "external addition method", "internal holding method" and "crop leaf spraying method". "External addition method" means adding trace element solvent or powder during rice processing. For the fortified rice produced by this method, most of the elements will be lost...

Problems solved by technology

[0004] The difference between these two inventions and the present application is that the present application also contains chromium, and the shortcoming that also exists in these two inventions is: two kinds of trace elements are mixed together and sprayed to rice, and the elements will cancel each other or Due to excessive heavy metals deposited on the plant to form dead knots and unable to reach the grain, the content of selenium and zinc in the harvested rice is low

And it is sprayed during the three periods of tillering stage, booting stage and filling stage to increase labor intensity and labor cost
