NOVELTY - Zinc-iron-selenium-rich pollution-free organic fertilizer comprises agricultural waste, Stellera chamaejasme, hops, pepper, Ginkgo skin, common cnidium fruit, cortex Meliae, quisqualis, Chinese gall, pubescent holly root, matrine, soapberry seed coat, sodium selenite, ferrous sulfate, ammonium carbonate, diammonium phosphate, potassium chloride, zinc sulfate, boric acid, medical stone powder, jennite powder, bentonite, thiourea, kieselguhr, powdered rock phosphate, and sodium humate.    USE - Zinc-iron-selenium-rich pollution-free organic fertilizer used for treating cereal, fruit tree, vegetable, and crop i.e. cucumber (all claimed).    ADVANTAGE - The zinc-iron-selenium-rich pollution-free organic fertilizer has good weeding effect and is safe to environment and unlikely to generate weed drug resistance.    DETAILED DESCRIPTION - Zinc-iron-selenium-rich pollution-free organic fertilizer comprises 80-100 pts. wt. agricultural waste, 1-15 pts. wt. S. chamaejasme, 5-10 pts. wt. hops, 25-30 pts. wt. pepper, 25-30 pts. wt. Ginkgo skin, 26-30 pts. wt. common cnidium fruit, 17-30 pts. wt. cortex Meliae, 16-25 pts. wt. quisqualis, 1-15 pts. wt. Chinese gall, 5-15 pts. wt. pubescent holly root, 5-10 pts. wt. matrine, 55-60 pts. wt. soapberry seed coat, 55-60 pts. wt. sodium selenite, 45-55 pts. wt. ferrous sulfate, 35-45 pts. wt. ammonium carbonate, 20-30 pts. wt. diammonium phosphate, 5-10 pts. wt. potassium chloride, 1-2 pts. wt. zinc sulfate, 1-2 pts. wt. boric acid, 25-30 pts. wt. medical stone powder, 5-10 pts. wt. jennite powder, 20-25 pts. wt. bentonite, 5-15 pts. wt. thiourea, 10-20 pts. wt. kieselguhr, 10-20 pts. wt. powdered rock phosphate, and 5-15 pts. wt. sodium humate. An INDEPENDENT CLAIM is included for preparation of zinc-iron-selenium-rich pollution-free organic fertilizer comprising stacking agricultural waste at 50 degrees C, fermenting for 35-45 days, turning the stack for every 5-7 days, baking or drying until moisture content is 25-35 wt.%, adding 1-5 pts. wt. microbial fermentation liquor to 95-99 pts. wt. decomposed organic material, adjusting the water content to 60-70 wt.%, adjusting the pH at 6.5-7.5, fully and uniformly mixing, where pile height is 0.4-0.6 m, covering with sacks or mats to control the material temperature at 25-30 degrees C, turning the stack everyday, fermenting for 5-8 days, adjusting the water content at 20-22 wt.%, adding 5-10 wt.% mushroom residue, 6-10 wt.% straw ash, and 600-1000 g/ton arbuscular mycorrhizal fungi agent to obtain biological organic fertilizer, taking Chinese stellera root, hops, pepper, Ginkgo, common cnidium fruit, quisqualis, Chinese gall, pubescent holly root, radix Sophorae flavescentis, and soapberry peel, reflux extracting for 2 times, each for 3 hours and using 30 times of 70% ethanol, combining the extracts, decompressing and concentrating the filtrate at 65 degrees C to obtain an extract having relative density of 1.6, spray drying to obtain dry extract powder, dispersing the dry extract powder in distilled water to obtain extract solution, adding sodium selenite, ferrous sulfate, diammonium phosphate, potassium chloride, zinc sulfate, boric acid, medical stone powder, jennite powder, bentonite, thiourea, kieselguhr, powdered rock phosphate, and sodium humate to obtain inorganic fertilizer, adding with bio-organic fertilizer and extract solution, where mass ratio of bio-organic fertilizer and inorganic fertilizer is 3-4:1-2, and mixing uniformly to obtain the zinc-iron-selenium-rich pollution-free organic fertilizer.
