NOVELTY - An enzyme-containing bio-organic fertilizer (A) comprises raw materials consisting of 10-50 pts. wt. potassium fulvate, 1-5 pts. wt. biological complex enzyme, 10-50 pts. wt. livestock manure, 0-5 pts. wt. amino acid, 1-5 pts. wt. biological bacteria, and 10-50 pts. wt. tobacco waste.    USE - Enzyme-containing bio-organic fertilizer (A) used for crop production.    ADVANTAGE - The enzyme-containing bio-organic fertilizer (A) has combined inorganic and organic fertilizer effects. It can effectively provide an improved soil organic matter-generating microorganism source; regulate soil acidity and alkalinity; produce active substances which can stimulate the growth of crops, fix nitrogen in air, facilitate nutrient conversion, promote crop nutrient absorption, and enable secretion of elements necessary for stimulating the growth and development of plant roots; inhibit the activity of harmful microorganisms; increase soil buffer property; and facilitate ecological waste reduction. Further, it is configured with reasonable formulation suitable for different types of soil, and can effectively improve and fertilize soil, prevent soil depletion, increase crop production yield, and turn waste into treasure, thus providing large economic value.    DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for preparation of enzyme-containing bio-organic fertilizer (A), comprising:    (1) preprocessing raw materials by (a) crushing tobacco waste into 50-mesh powder, adjusting the carbon-to-nitrogen ratio to 25:1 using grass-derived carbon, regulating the pH to 6.5-7.5 using calcium hydroxide (Ca(OH)2), and then regulating the moisture content to 45 wt.% to obtain preprocessed tobacco waste; and (b) fermenting livestock manure for 7-10 days at 60-80 degrees C, and repeating the fermentation process for 3-4 times to obtain preprocessed livestock manure;    (2) uniformly mixing 35 pts. wt. preprocessed livestock manure, 31 pts. wt. preprocessed tobacco waste, 25 pts. wt. potassium fulvate, 3 pts. wt. biological complex enzyme, 3 pts. wt. amino acid, and 3 pts. wt. biological bacteria; subjecting into stacking fermentation process for 3-4 times; and    (3) drying the fermented material, and then sieving to obtain the fertilizer (A).
