NOVELTY - Straw fermentation of organic fertilizer comprises drying crop straw (rice straw, Asparagus straw, rape straw, wheat straw and/or corn straw), adding into a reaction kettle, inoculating fermentative bacteria (e.g. Bacillus licheniformis, Bacillus megaterium, Bacillus macerans and/or Bifidobacteria), adding water and burying, isolating air, carrying out anaerobic fermentation, pumping the upper clear liquid into a material storage tank after fermentation, adding animal manure (chicken manure, pig manure and/or pigeon manure) and mixing.    USE - The method is useful for straw fermentation of organic fertilizer (claimed).    ADVANTAGE - The method: has short fermentation time; is suitable for large scale industrial production; ensures complete sterilization, eliminates bacteria and residual seed, which avoids crop pests and diseases; and improves the agricultural product purity and quality after crop seed germination and growth. The fertilizer ensures growth of agricultural and forest crops beneficial microorganisms; improves soil, increases soil fertility, increases immune of agricultural and forest crops, thus improving grain yield.    DETAILED DESCRIPTION - Straw fermentation of organic fertilizer comprises drying crop straw, adding into a reaction kettle, inoculating 2% fermentative bacteria, adding water and burying, isolating air, carrying out anaerobic fermentation at 30 degrees C at a pressure of 1.51-2.01 MPa for 7-9 days, pumping the upper clear liquid into a material storage tank after fermentation, adding 17% animal manure, mixing, where the fermentative bacteria is Bacillus circulans, Bacillus licheniformis, Bacillus megaterium, Bacillus subtilis, Bacillus macerans, Bifidobacteria, pressed yeast and/or Nocardia. The crop straw is rice straw, Asparagus straw, rape straw, wheat straw and/or corn straw. The animal manure is chicken manure, pig manure and/or pigeon manure. An INDEPENDENT CLAIM is also included for straw fertilizer composition, comprising 80-84% organic fertilizer as mentioned above, 2-7% calcium superphosphate, 2-3% ammonium sulfate, 1-6% zinc sulfate and 3-5% borax.
