Green microbial biofertilizer

The invention discloses a green microbial fertilizer which comprises the following components in parts by weight: 80-120 parts of rice straw, 50-60 parts of corn straw, 30-40 parts of bean straw, 10-25 parts of potato straw, 15-28 parts of rape cake, 20-35 parts of chicken manure, 20-35 parts of pig manure, 8-10 parts of calcium biphosphate, 1-3 parts of trimetapyrophosphoric acid, 2-8 parts of potassium dihydrogen phosphate, 1-3 parts of ammonium monoacid phosphate, 1-3 parts of calcium biphosphate, 1-2 parts of calcium biphosphate and 1-2 parts of boric acid. The invention is non-toxic, harmless and pollution-free, can supply nitrogen, phosphorus and potassium fertilizers to crops, and can supply necessary microelements; after being applied, the fertilizer does not harden the soil, and can improve the soil structure; and the invention has strong water-holding capacity, especially has better effect for dry crops, and has longer fertilizer efficiency.
