Organic selenium-rich fertilizer

Abstract

The invention provides an organic selenium-rich fertilizer. The organic selenium-rich fertilizer is obtained by adding water to animal wastes, residual vegetables, food residues and other wastes as well as rape seed cakes; fermenting the mixture; filtering the mixture by 120-200 meshes; adding the sodium selenate to the filtered mixture; and dissolving the mixture, wherein the concentration calculated by selenium element is 25-35 g/L. During the stable period of the rice, 150 ml selenium-rich fertilizer diluted by 550-700 times of water is sprayed to each acre of land. The application effect is that the selenium content of the agricultural product can be obviously increased and the percentage of the organic selenium in the total selenium of the agricultural product is obviously increased; moreover, the organic selenium-rich fertilizer provided by the invention is suitable for being used in domestic selenium deficient or low-selenium regions and has positive significance on increasing the selenium level of the crowd.

Description

Technical field: [0001] The invention belongs to the technical field of fertilizer production and relates to an organic selenium-enriched fertilizer. Background technique: [0002] Selenium is one of the essential trace elements for humans and animals. It has been recognized by the world for its important role in cancer prevention, anti-cancer, prevention and treatment of cardiovascular diseases, Keshan disease and Kaschin-Beck disease. Selenium can significantly reduce the risk of breast cancer. , skin cancer, colon cancer, liver cancer and other cancers, and has special physiological functions such as relieving heavy metal poisoning. The latest research by American scientists also proves that selenium deficiency in the body is a common feature of AIDS patients. "Selenium chemical protection" has become the focus of research by many scientists in the world. [0003] Strengthening the development of selenium-rich foods has important commercial and economic value, and it ca...
