Sugarcane mud organic fertilizer with Bacillus subtilis and preparation method thereof

Abstract

The invention discloses a sugarcane mud organic fertilizer with Bacillus subtilis and a preparation method thereof. industrial sugarcane mud is used as a main material; a biological bacterial agent, rice bran, animal waste, straws, tea cake, quick lime and a micro fertilizer are used as auxiliary materials. Bacillus subtilis used herein has a great ability to produce cellulase and lignin peroxidase and can decompose cellulose, lignin and other organics in the organic wastes, such as sugarcane mud, rice bran, straws, and tea cake; the sugarcane mud organic fertilizer with Bacillus subtilis andthe preparation method thereof have the advantages of high organics-decomposing ability, high decomposition degree, secondary aging, zero need for floor area, high automation level, and zero secondaryenvironmental pollution; fermenting equipment can run in enclosed manner, and materials under different fermenting dates are fully separated, so that fermenting speed of the organic fertilizer can beevidently increased and fermenting cycle can be shortened; no foul odor occurs, so that the quality of compost products is improved.

Description

technical field [0001] The invention relates to an organic fertilizer, in particular to a sugarcane filter mud organic fertilizer containing Bacillus subtilis and a preparation method thereof. Background technique [0002] Many scientific research institutes in my country have extensive research on aerobic fermentation strains and processes, and more and more industrially produced strains are transformed into products by production enterprises, but their disadvantages are gradually becoming more and more serious with the tightening of environmental protection policies. The more typical examples are the biological treatment of livestock and poultry manure and the restoration of soil degradation. [0003] Bacillus subtilis ( Bacillus subtiles ) is a kind of Gram-positive bacteria with aerobic endophytic spores. It exists widely in nature, not only in soil, plant rhizosphere, body surface and other external environments, but also is a common endophytic bacteria in plants. It i...

Problems solved by technology

[0004] In recent years, under the supervision of China's environmental protection and animal production management departments, some large-scale farms with strong funds have successively carried out livestock and poultry manure treatment, but there are great differences in the selection of treatment methods, process design, and treatment scale. There are many problems The current composting production process mainly has the following problems: First, some small and medium-sized farms and chicken manure processing plants use simple open stacking or static ventilation fermentation methods to process animal manure, which is backward in technology, low in mechanization, and occupies a large area , the compost smell and sewage have a great impact on the surrounding environment, it is difficult to control the breeding of mosquitoes and flies, and the weather and environment are greatly affected. The compost field often becomes a pollution source for the farm and the surrounding areas, and the quality of the compost produced is even more difficult to guarantee; the second is Some large-scale farms mostly use tank-type turning fermentation to process animal manure. In order to facilitate mechanical operation and water vapor volatilization, open type is generally used, and it occupies a large area. Ventilation and oxygenation are not easy to operate, water volatilization is slow, and the fermentation cycle is generally long. 25-30 days, the energy consumption is large, and it is easily affected by the climate; third, although some large-scale farms use self-propelled compost turning and throwing machines imported from Germany and Finland, the mechanical maintenance is complicated and expensive, and it is only suitable for open, Stack fermentation in dry and rainless area

[0005] At present, the fermentation of organic fertilizers often adopts the common drying method, composting method and feed method. The conventional composting method is slow in decomposition, takes a long time, and causes serious environmental pollution; while the drying method and feed method produce a large amount of extreme Smelly ammonia gas, with the increase of pH value and the volatilization of ammonia gas, will cause the loss of nitrogen, and the effect of organic fertilizer will not be achieved if the decomposition is not complete

The process of producing organic fertilizer in the prior art has many disadvantages, such as long production cycle of fermentation production mode, large production area, high production cost, slow fermentation of organic fertilizer, long cycle, and incomplete decomposition of organic fertilizer
