Abstract

The invention belongs to the technical field of agricultural fertilizer and particularly relates to a preparation method of selenium-rich organic fertilizer by waste recycling. The preparation methodcomprises the following steps: mixing selenium-rich crop leaves and stems with animal waste and corn straw, adding compound microorganisms, performing fermentation under a closed environment, pulverizing fermented products, and then adding humate and linoleic acid to obtain selenium-rich organic fertilizer powder; and uniformly mixing the selenium-rich organic fertilizer powder with nitrogen fertilizer, phosphate fertilizer, potassium fertilizer, a urease inhibitor, an ammonia stabilizing agent and a granulating agent, and performing granulation to obtain selenium-rich biological controlled-release organic fertilizer. The preparation method of the selenium-rich organic fertilizer by waste recycling, provided by the invention, is used for preparing the selenium-rich organic fertilizer by utilizing agricultural waste, the selenium-rich organic fertilizer can be absorbed by crops and converted into biological organic selenium to be enriched in the crops, the selenium content of seeds andfruits of the crops can be increased by 5-20 times, and common people can eat the selenium-rich agricultural products to supplement selenium required for human bodies, thereby achieving the purposes of preventing diseases, enhancing physique, keeping healthy and prolonging life. The organic fertilizer is scientific and reasonable in formula, simple and convenient in production and use methods, lowin cost and safe and effective.

Description

technical field [0001] The invention belongs to the technical field of agricultural fertilizers, in particular to a method for preparing selenium-enriched organic fertilizers which are reused from waste. Background technique [0002] Selenium is an indispensable trace element in the human body. It has anti-cancer and anti-oxidation effects, can antagonize harmful heavy metals, can regulate the absorption and utilization of vitamin A, vitamin C, vitamin E, and vitamin K, and can regulate the synthesis of proteins. There is no long-term selenium storage organ in the human body. The selenium needed by the body should be continuously obtained from the diet in sufficient amount. The balance of selenium concentration plays an important role in protecting and promoting the physiological functions of many organs and tissues. [0003] There are many ways to supplement selenium, but practice has proved that medicine supplement is not as good as food supplement, and food supplement has...
