The invention discloses a method for quickly producing a bio-organic fertilizer by using tobacco stalks and the bio-organic fertilizer. The raw materials for producing the bio-organic fertilizer in the method comprise the following substances in percentage by weight: 30 to 70 percent of tobacco stalks subjected to steam explosion treatment, 20 to 50 percent of mixed accessories, 5 to 15 percent of conditioning agent and 1 to 5 percent of microbial flora; and the bio-organic fertilizer is prepared through an aerobic composting process, wherein the stacking C/N ratio is adjusted to be 25 to 35/1, the water content is adjusted to be 50 to 65 percent, the pH is controlled to be 5.0 to 8.5, the strip stamping height is 1.0 to 1.5 m, and the tobacco stalks are crushed, screened and packaged after reaching a maturity index. The method has the characteristics of fast treatment, high efficiency and fast maturity, and has an important practical significance for fully using wasted tobacco stalk resources, improving the ecological environment of tobacco planting areas and reducing environmental pollution. The bio-organic fertilizer has high organic content, has the effects of improving the soil structure and improving the soil fertility, and can be widely used for planting economic crops of tobaccos, vegetables and the like.
