The invention belongs to the technical field of agricultural microbe and also relates to the technical field of tobacco leaf ageing. The invention discloses a microbial highland bacillus altitudinis D2 strain which is preserved in China Center for Type Culture Collection, the preserving number is CCTCCNO: m2011056, the invention further discloses the application of the highland bacillus altitudinis D2 strain in artificial ageing of tobacco leaves at the upper part of flue-cured tobacco. The highland bacillus altitudinis is fragtant adding and upgrading dominant bacteria separated from the surfaces of tobacco leaves, can ensure artificial ageing to tobacco leaves at the upper part of flue-cured tobaccom, shortens the aging time of the tobacco leaves at the upper part, improves the sucking quality of tobacco leaves at the upper part of flue-cured tobaccom, increases aroma quality and concentration of aroma, and reduces excitant.

The invention discloses a preparation method of a composite bacterial agent for sludge composting and application thereof. The preparation method comprises the following steps: separately culturing bacillus altitudinis, purple streptomyces variabilis, bacillus stearothermophilus, bacillus subtilis and bacillus licheniformis, then mixing according to a volume ratio of bacterial liquid to obtain mixed bacterial liquid, then inoculating a fermentation medium with the mixed bacterial liquid, and performing enlargement culture to obtain the composite bacterial agent for sludge composting. The composite bacterial agent is mainly applied to high-temperature sludge composting, raises the fermentation temperature fast, maintains high temperature for a long time, can shorten the composting time, reduces the moisture content of a composted material, is low in production cost, environmentally friendly, pollution-free, excellent in performance and high in efficiency, and has relatively good economic benefits and social benefits.

The invention belongs to the technical field of plant disease biocontrol, and discloses a strain of bacillus altitudinis XJGS-4 and an application thereof in prevention and treatment of peronophythoralitchii.
