Production method of organic selenium-iron-zinc-rich nutrition enhanced rice

Abstract

The invention relates to a production method of selenium-iron-zinc-rich rice, in particular to a production method of preparing the selenium-iron-zinc-rich rice through applying selenium-iron-zinc-rich organic and inorganic special fertilizers. The production method of organic selenium-iron-zinc-rich nutrition enhanced rice sequentially comprises the following steps of: seed selection, seedling culturing, field cultivation, rice seedling transplanting, field management, harvesting and processing, wherein the field management comprises fertilization, the applied fertilizers are the selenium-iron-zinc-rich organic and inorganic special fertilizers, the number of fertilization times is 1 to 4, and the selenium-iron-zinc-rich organic and inorganic special fertilizers comprise selenite, ferrite, zinc salts, nitrogenous fertilizers, phosphatic fertilizers, potash fertilizers, polyaspartic acid, polyaspartate, decomposed organic fertilizers and silicon fertilizers. Through the application of the selenium-iron-zinc-rich fertilizers, selenium, iron and zinc elements and other nutrition enhanced substances required by growth are simultaneously provided for crops, the application of the fertilizers is favorable for the crop growth, the absorption rate and the conversion rate of selenium, iron and zinc are improved, and the selenium-iron-zinc-rich rice conforming to the food standard is produced.

[0001] The invention relates to a production method of selenium-rich iron-zinc rice, in particular to a production method for preparing selenium-rich iron-zinc rice by applying selenium-rich iron-zinc organic and inorganic fertilizers in the field. 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 ...
