Abstract

The invention relates to a formula of a fertilizer, and a using method for the fertilizer. A selenium and ferrum-enriched organic inorganic fertilizer used for producing selenium and ferrum-enriched rice is prepared by mixing selenite, ferrite, a nitrogen fertilizer, a phosphate fertilizer, a potash fertilizer, a decomposed organic fertilizer and a silicon fertilizer in a ratio, and granulating. The selenium and ferrum-enriched organic inorganic fertilizer is prepared from the following components in part by weight: 0.004 to 0.010 part of selenite, 1 to 5 parts of ferrite, 15 to 33 parts of nitrogen fertilizer, 12 to 24 parts of phosphate fertilizer, 10 to 17 parts of potash fertilizer, 0.02 to 0.08 part of sodium of polyaspartic acid or salt thereof, 30 to 50 parts of decomposed organic fertilizer and 5 to 8 parts of silicon fertilizer. The fertilizer contains selenium and ferrum, also contains other nutritional fortification substances required by growth of crops, can simultaneously provide selenium, ferrum and nutritional fortification substances required by the growth for the crops, contributes to the growth of the crops, improves the absorption rate and conversion rate of the selenium and the ferrum, and achieves an effect of producing the selenium and ferrum-enriched rice reaching the selenium and ferrum-enriched rice standard by applying a small amount of selenium and ferrum.

Description

technical field [0001] The invention relates to a fertilizer, in particular to a fertilizer for producing selenium-enriched iron rice, and also relates to an application method of the fertilizer. Background technique [0002] Selenium is an essential trace element for humans and animals. It is an antioxidant that can relieve aging and eliminate a variety of harmful free radicals. Its synergistic effect with vitamin E is called the "golden partner" of anti-oxidation. As the only specific micronutrient (selenocysteine, the 21st amino acid) in the human genome, its importance has been demonstrated (Rayman, M P. 2002, The argument for increasing selenium intake. Proceeding of the Nutrition Society, 61: 203-215). Selenium deficiency will lead to the decline of human immunity, which will lead to the occurrence of Keshan disease and Kaschin-Beck disease. Severe selenium deficiency will lead to more than 40 kinds of diseases, such as coronary heart disease, hemolytic anemia and liv...
