NOVELTY - Rape base fertilizer comprises e.g. biogas residue (30-40 parts by weight (pts.wt.), rape seed cake cypress (20-30 pts.wt.), weathered coal (5-10 pts.wt.), gelatin (5-10 pts.wt.), biological bacterium (4-8 pts.wt.), ammonium hydrogen carbonate (20-25 pts.wt.), monoammonium phosphate (20-25 pts.wt.), potassium sulfate (5-8 pts.wt.), tea seed phellodendron (15-20 pts.wt.), carboxymethyl cellulose (4-6 pts.wt.), sulfuric acid (30%), lime (20-25 pts.wt.), ferrous sulfate (1-2 pts.wt.), ammonium sulfate (1-2 pts.wt.), and manganese sulfate (1-2 pts.wt.).    USE - As a rape base fertilizer (claimed), for treating plant disease; and killing insect.    ADVANTAGE - The fertilizer is capable of improving soil, which is good for effective release fertilizer effect; is safe, without having pollution to the environment and crop; and improves yield and the quality of the rape, thus improves the economic benefit of the rape.    DETAILED DESCRIPTION - Rape base fertilizer comprises biogas residue (30-40 parts by weight (pts.wt.), rape seed cake cypress (20-30 pts.wt.), weathered coal (5-10 pts.wt.), gelatin (5-10 pts.wt.), biological bacterium (4-8 pts.wt.), ammonium hydrogen carbonate (20-25 pts.wt.), monoammonium phosphate (20-25 pts.wt.), potassium sulfate (5-8 pts.wt.), tea seed phellodendron (15-20 pts.wt.), carboxymethyl cellulose (4-6 pts.wt.), sulfuric acid (30%), lime (20-25 pts.wt.), ferrous sulfate (1-2 pts.wt.), ammonium sulfate (1-2 pts.wt.), manganese sulfate (1-2 pts.wt.), carbon nano (2-5 pts.wt.), nano-phosphate powder (2-5), chinaberry bark leaf extract (2-5), and liquid paraffin (3-4). An INDEPENDENT CLAIM is included for preparation of the rape base fertilizer involving firstly taking tea seed, adding phellodendron into 30% sulfuric acid, at 100-110 degrees C to hydrolyze for 1-2 hours, generating amino acid, then adding lime to neutralize to pH value of 6, then adding carboxymethyl cellulose, at last adding ferrous sulfate, ammonium molybdate, manganese sulfate to dissolve, at 90-105 degrees C to react for 5-6 hours, generating amino acid chelate, and fertilizer solution, carrying out compost fermentation, taking biogas residue, rape seed cake cypress adding biological bacteria, after mixing evenly, piling and fermenting for 5-10 days, again fermenting for 30-40 days, to obtain the organic fertilizer; mixing ammonium bicarbonate, monoammonium phosphate, and potassium sulfate, and crushing, adding glutin and inorganic slow release agent, soil composition of weathered coal, smashing, passing by 100-200 items sieve to obtain nitrogen-phosphorus-potassium fertilizer; mixing the nitrogen-phosphorus-potassium fertilizer with nanometer carbon nanometer phosphate powder, chinaberry bark, and leaf extract, uniformly, then spraying amino acid chelate, adding fertilizer solution to granulate, and then spraying coating liquid to obtain the rape base fertilizer.
