Problems solved by technology

Second, the Chinese dietary structure results in limited selenium intake
More importantly, in the 4th to 11th examples in which the above-mentioned fertilizers were applied to make the rice produced meet the national standard for selenium-enriched rice, the amount of selenium in the fertilizers used throughout the growing season of rice reached 8000~ 54545 mg / mu, the amount of selenium is still relatively large, high concentration of selenium fertilizer increases the cost of fertilizer, and because selenium is toxic, excessive selenium pollutes the runoff water and soil in the field, and is a great waste

Abstract

The invention relates to a fertilizer formula and further relates to an application method of the fertilizer. A selenium-rich organic/inorganic fertilizer for producing selenium-rick rice is prepared by mixing selenites, nitrogenous fertilizers, phosphate fertilizers, potash fertilizers, rotten organic fertilizers and silicon fertilizers according to a certain ratio and pelletizing the mixture. The selenium-rich organic/inorganic fertilizer for producing the selenium-rick rice comprises the following components in parts by weight: 0.004-0.010 parts of the selenites, 15-33 parts of the nitrogenous fertilizers, 12-24 parts of the phosphate fertilizers, 10-17 parts of the potash fertilizers, 30-50 parts of the rotten organic fertilizers and 5-8 parts of the silicon fertilizers. The fertilizer not only includes selenium element but also includes other nutrition enhancing matters requested by crop growth. As the fertilizer can be used for supplying the selenium element and the other nutrition enhancing matters requested in growth for crops simultaneously, the application of the fertilizer is good for the crop growth, so that the absorption rate and the conversion rate of selenium are improved, and the selenium-rick rice reaching a selenium-rick rice standard can be produced by applying less selenium.

Description

Technical field [0001] The present invention involves a fertilizer, which specializes in a fertilizer for the production of selenium -rich rice, and the application method of the fertilizer. Background technique [0002] Selenium is a trace element necessary for humans and animals. It is a antioxidant, which has the effect of alleviating aging. It can eliminate a variety of harmful free radicals. The synergistic effect of vitamin E is called "golden partner" called antioxidant.As the only special trace nutrition in the genome of the human genome (selenium -agent cysteine, the 21st amino acid), its importance has been confirmed (Rayman, M P. 2002, The Argument for Increasing Selenium Intake. Proceeeding of theNurtrition society, 61: 203-215).Selenium deficiency can lead to a decline in human immunity, which will cause the occurrence of mountain diseases and bone bone ancestors. Severe selenium deficiency will cause more than 40 diseases, such as coronary heart disease, hemolytic a...
