NOVELTY - Fertilizer comprises e.g. 60-80 pts. wt. livestock manure, 20-50 pts. wt. biogas residue, 5-15 pts. wt. rapeseed meal, 3-7 pts. wt. vermiculite powder, 5-10 pts. wt. silkworm excrete, 3-8 pts. wt. weathered coal, 5-10 pts. wt. egg shell powder, 20-40 pts. wt. tea leaves residue, 3-8 pts. wt. composite leavening agent and 2-10 pts. wt. The composite leavening agent is e.g. Bacillus subtilis, silicate bacteria, Lactococcus lactis, Actinomycetes, circular brown Azotobacter, Bacillus megaterium and/or gelatinous Bacillus sp..    USE - The fertilizer is useful for cultivating mulberry (claimed).    ADVANTAGE - The fertilizer meets the nutrient requirements of plant at various stages, and improves fruit and yield.    DETAILED DESCRIPTION - Fertilizer, comprises 60-80 pts. wt. livestock manure, 20-50 pts. wt. biogas residue, 5-15 pts. wt. rapeseed meal, 3-7 pts. wt. vermiculite powder, 5-10 pts. wt. silkworm excrete, 3-8 pts. wt. weathered coal, 5-10 pts. wt. egg shell powder, 20-40 pts. wt. tea leaves residue, 8-16 pts. wt. bamboo charcoal, 2-9 pts. wt. furfural residue, 10-20 pts. wt. boron, 1-5 pts. wt. ferrous sulfate, 1-5 pts. wt. manganese sulfate, 2-6 pts. wt. ammonium molybdate, 1-4 pts. wt. copper sulfate, 4-8 pts. wt. humic acid, 4-9 pts. wt. Chinese wood oil, 3-8 pts. wt. composite leavening agent and 2-10 pts. wt. Arbuscular mycorrhiza. The composite leavening agent is Bacillus subtilis, silicate bacteria, Lactococcus lactis, Actinomycetes, circular brown Azotobacter, Bacillus megaterium, gelatinous Bacillus sp. Escherichia coli, cellulase, phosphorylase and/or protease. Preparation of fertilizer comprises: (i) crushing livestock manure, biogas residue, rapeseed meal, vermiculite powder and silkworm excrete, mixing uniformly to obtain material (A); (ii) adding weathered coal, egg shell powder, tea leaves residue, bamboo charcoal and furfural residue to material (A) and mixing uniformly to obtain material (B); (iii) adding boron, ferrous sulfate, manganese sulfate, ammonium molybdate, copper sulfate and humic acid to material (B), stirring uniformly, fermenting to obtain fermented material (C), where the fermentation conditions are temperature is 21-26 degrees C and time is 3-5 days; (iv) adding composite leavening agent to fermented material (C), fermenting for second time to obtain material (D), where fermentation conditions are temperature is 22-28 degrees C and time is 2-5 days; and (v) adding Chinese wood oil and Arbuscular mycorrhiza to material (D), stirring, drying and granulating.
