NOVELTY - A biological fertilizer includes 35-40 pts. wt. rapeseed cake, 18-20 pts. wt. tobacco waste, 10-20 pts. wt. corn straw, 10-20 pts. wt. wheat straw, 30-50 pts. wt. large garlic bulb and betel nut slag, 10-15 pts. wt. fungal biomass protein, 10-20 pts. wt. slow-release potassium chloride, 8-10 pts. wt. sawdust powder, 8-10 pts. wt. staff vine, 8-10 pts. wt. cinnamic aldehyde, 8-10 pts. wt. eugenol, 10-12 pts. wt. herba patriniae, 20-40 pts. wt. cattle and sheep excrement, 10-22 pts. wt. nitrogen-phosphorus-potassium fertilizer, 3-5 pts. wt. biological preparation, and 1.5 pts. wt. zinc sulfate.    USE - Biological fertilizer used for preventing and treating plant diseases and insect pests.    ADVANTAGE - The fertilizer can supplement needed nutrients to plants and can increase yield.    DETAILED DESCRIPTION - A biological fertilizer comprises 35-40 pts. wt. rapeseed cake, 18-20 pts. wt. tobacco waste, 10-20 pts. wt. corn straw, 10-20 pts. wt. wheat straw, 30-50 pts. wt. large garlic bulb and betel nut slag, 10-15 pts. wt. fungal biomass protein, 10-20 pts. wt. slow-release potassium chloride, 8-10 pts. wt. sawdust powder, 8-10 pts. wt. staff vine, 8-10 pts. wt. cinnamic aldehyde, 8-10 pts. wt. eugenol, 10-12 pts. wt. herba patriniae, 20-40 pts. wt. cattle and sheep excrement, 10-22 pts. wt. nitrogen-phosphorus-potassium (NPK) fertilizer, 3-5 pts. wt. biological preparation, 1.5 pts. wt. zinc sulfate, 1.5 pts. wt. magnesium sulfate, 1.5 pts. wt. sodium silicate, and 2.5 pts. wt. borax. The biological preparation comprises enzymes. Weight ratio of the large garlic stick and betel nut slag is 1:1.5-4. An INDEPENDENT CLAIM is included for preparation of the fertilizer, comprising:    (A) mixing and crushing rapeseed cake, tobacco waste, corn straw, wheat straw, and large garlic bulb and betel nut slag, then adding slow-release potassium chloride, sawdust powder, staff vine, cinnamic aldehyde, eugenol, herba patriniae, cattle and sheep excrement, NPK fertilizer, and biological preparation, and mixing;    (B) stacking the mixture and carrying out high temperature fermentation for 30-40 days, and turning stack within 5-10 days of fermentation process;    (C) when white hypha of the stack is generated, stopping fermentation to obtain organic fertilizer; and    (D) adding fermented organic fertilizer with zinc sulfate, magnesium sulfate, sodium silicate, borax, fungal biomass protein, and uniformly mixing to obtain the biological fertilizer.
