Abstract

The invention discloses a cassava fermentation residue selenium-rich high-calcium organic fertilizer. The fertilizer is prepared from, by weight, 230-280 parts of cassava residues, 40-60 parts of sodium selenite, 15-20 parts of calcium glycinate, 12-18 parts of calcium nitrate, 10-16 parts of calcium sulfite, 30-50 parts of pig manure, 25-45 parts of chicken manure, 20-28 parts of duck manure, 18-30 parts of earthworm powder, 12-16 parts of compound bacteria, 2.2-3.4 parts of microelement, 2-4.5 parts of organic water-retaining agent, 1.2-2.4 parts of dispersing agent, 0.9-2 parts of organic conditioner, 0.8-1.8 parts of penetrating agent, 0.6-1 part of conditioning agent, 1-1.8 parts of tackifier and 0.4-0.8 part of synergist. The cassava fermentation residue selenium-rich high-calcium organic fertilizer can improve the water holding capacity of soil, improve the soil structure, improve the water utilization efficiency, promote the rapid and healthy growth of rice and improve the selenium content and the economic value of the rice.

Description

[0001] 【Technical field】 [0002] The invention belongs to the technical field of fertilizer preparation, and in particular relates to a selenium-enriched and high-calcium organic fertilizer of cassava fermented residue. [0003] 【Background technique】 [0004] Selenium is one of the 14 essential trace elements for the human body. It is known as "the fire of life", "the patron saint of the heart" and "the king of anti-cancer". Recognition ability, improve the synthesis of immune system cell antibodies, the proliferation of T cells, the level of antibodies in the blood, and double the phagocytosis and bactericidal ability of macrophages, thereby enhancing the immune function of the human body. Animal experiments have found that selenium can reduce the acute injury of aflatoxin Bl, reduce the degree of necrosis of the liver center lobule and the role of mortality. Selenium has a strong affinity with certain heavy metal elements, and combines with metals such as mercury and sulfu...
