The invention discloses a highland barley biological control disease-resistant and growth promoting method. The highland barley biological control disease-resistant and growth promoting method comprises the steps that bacillus subtilis are made into high density bacterial suspension with the density ranging from 109cfu/mLto 1010cfu/mL; healthy highland barley straws are cut into small sections to compost, the bacillus subtilis high density bacterial suspension is sprayed in the composting process, a biological fertilizer capable of effectively restraining and killing highland barley pathology funguses is obtained after fermentation and is used on highland barley biological control disease-resistant and growth promotion. According to the highland barley biological control disease-resistant and growth promoting method, the bacillus subtilis producing beta dextranase are plant probiotics with a disease-resistant and growth promoting function, the biological fertilizer is added into the compost to effectively strengthening the biological control function on highland barley disease funguses, restraining and killing effects on sheath rot pathogenic bacteria are showed, and the highland barley yield is improved. According to the highland barley biological control disease-resistant and growth promoting method, treatment of the composting process is easy, no waste water is discharged, the investment is small, the energy consumption is low, the operation is easy, industrialized mass production is easy to achieve, the economic benefit is good, and the application prospect is wide.
