Legume special-purpose sheep manure fermented fertilizer and preparation method thereof

Abstract

The invention relates to legume special-purpose sheep manure fermented fertilizer and a preparation method thereof. The legume special-purpose sheep manure fermented fertilizer is prepared from 90 to120 parts by mass of sheep manure, 10 to 12 parts by mass of peanut seedlings, 8 to 20 parts by mass of sweet potato vines, 5 to 20 parts by mass of broussonetia papyrifera sawdust, 8 to 10 parts by mass of mushroom residues, 2 to 5 parts by mass of charcoal, 3 to 5 parts by mass of fermentation bacteria and 4 to 6 parts by mass of mixed additives. Through combination of sheep manure composting fermentation and the medium / trace amount of fertilizer, fast-acting nutrients are supplied, the soil physicochemical properties are improved, the soil structure is improved, the crop growth is promoted,nutritional and health effects are obtained, and the environmental pollution and ecological damage caused by a large amount of chemical fertilizer and pesticide are prevented. Through use of microelements needed by the legume in the sheep manure fermented fertilizer, the organic-inorganic fertilizer application is realized, the pressure caused by use of a large amount of chemical fertilizer on the environment is greatly relieved, the problem that the yield per unit area cannot be greatly improved because of single use of organic fertilizer is solved, and the crop yield per unit area and cropquality are significantly improved.

Description

technical field [0001] The invention relates to a fermented fertilizer and a preparation method thereof, in particular to a special sheep dung fermented fertilizer for leguminous herbage and a preparation method thereof, belonging to the technical field of fermented fertilizers. Background technique [0002] In recent years, with the development of planting and sheep raising, a large amount of organic waste such as crop straw and sheep manure and urine has been produced, and it has increased year by year. my country produces nearly 700 million tons of crop straw every year. Except for some of which are used for industrial raw materials, livestock feed, manure returning to fields, and gasification for energy, most of the rest are discarded or incinerated, which not only wastes biomass resources, but also pollutes the environment. The water content in sheep manure is 65%, organic matter is 24% to 27%, nitrogen (N) is 0.7% to 0.8%, phosphorus (P 2 o 5 ) 0.45% ~ 0.6%, potassiu...

Problems solved by technology

[0005] The purpose of the present invention is to solve the problem that the existing organic wastes such as crop stalks, sheep manure and urine are not fully utilized, pathogenic bacteria and parasites in sheep manure, and other toxic and harmful substances, direct application of sheep manure is likely to cause pollution and cause disease , and the defects and deficiencies of poor fertilizer efficiency, we now provide a reasonable production process, which widely selects crop stalks and sheep manure as raw materials, which promotes the rapid growth of beneficial bacteria and inhibits the existence of pathogenic and harmful bacteria. A kind of sheep dung fermented fertilizer specially used for leguminous herbage, which can realize resource utilization, will not produce pollution and cause diseases, and has improved fertilizer efficiency, and its preparation method
