The invention belongs to the microbiology technology, and more specifically relates to Hafnia sp. YYBIO-001, and a preparation method, applications, and a bacteria preparation thereof. The preservation number of the Hafnia sp. YYBIO-001 is CGMCC No.145028. The Hafnia sp. YYBIO-001 is capable of promoting plant growth obviously, and achieving antagonistic action with a plurality of plant pathogenicfungus. The Hafnia sp. YYBIO-001 is obtained via separation screening from sugarcane plant samples, possesses ecological safety, is capable of promoting plant growth through combined nitrogen fixation and secretion of auxin, can be used for producing nitrogen-fixing microorganism bacteria preparations and biological organic fertilizers which are capable of promoting growth, reducing using of chemical fertilizer and pesticide, possesses important meaning in ecological environment protection, and is promising in application prospect.

Hafnia sp. YYBIO-001, and preparation method, applications, and bacteria preparation thereof

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.

Sugarcane mud organic fertilizer with Bacillus subtilis and preparation method thereof

The invention discloses a sugarcane filtered mud fermentation agent and a sugarcane filtered mud fermentation method. The sugarcane filtered mud fermentation agent comprises bacillus subtilis, aspergillus oryzae, saccharomycetes and trichoderma longibrachiatum, wherein the mass ratio of the bacillus subtilis, the aspergillus oryzae, the saccharomycetes and the trichoderma longibrachiatum is (14-16):(9-11):(4-6):(4-6). According to the sugarcane filtered mud fermentation agent, a plurality of strains are combined at a proper ratio, so that the temperature is raised quickly, the high-temperature time is long, the fermentation time is short and fermentation is conducted completely.
