NOVELTY - A special fertilizer for late rice base is prepared by using raw materials (parts by weight) e.g. traditional Chinese medicine slag, dregs (30-40 parts), weathered coal (20-30 parts), attapulgite (5-10 parts), biological bacterium (5-10 parts), urea (4-8 parts), calcium superphosphate (8-10 parts), potassium chloride (25-30 parts), feathers (10-15 parts), carboxymethyl cellulose (20-25 parts), 30% sulfuric acid (6-8 parts), lime (25-30 parts), zinc sulfate (1-2 parts), copper sulfate (1-2 parts), boric acid (1-2 parts), patrinia powder (2-5 parts), glutin (2-5 parts).    USE - For preparation of special fertilizer for late rice base (claimed).    ADVANTAGE - The special fertilizer for late rice base prepared by the method is rational formulation, comprehensive and balanced nutrition, has good use effect, can improve the fertilizer utilization rate, has high yield, improves quality of the late rice, so as to improve the economic benefit of the late rice. The rice base fertilizer efficiently prevents plant diseases and insect pests, has balanced nutrition, which can promote better crop grow, and improves the soil environment and crop yield.    DETAILED DESCRIPTION - A special fertilizer for late rice base is prepared by using raw materials (parts by weight): traditional Chinese medicine slag, dregs (30-40 parts), weathered coal (20-30 parts), attapulgite (5-10 parts), biological bacterium (5-10 parts), urea (4-8 parts), calcium superphosphate (8-10 parts), potassium chloride (25-30 parts), feathers (10-15 parts), carboxymethyl cellulose (20-25 parts), 30% sulfuric acid (6-8 parts), lime (25-30 parts), zinc sulfate (1-2 parts), copper sulfate (1-2 parts), boric acid (1-2 parts), patrinia powder (2-5 parts), glutin (2-5 parts), nanometer calcium carbonate powder (2-5 parts), and wintergreen oil (3-4). The method involves firstly, adding goose feather in 30% sulfuric acid, at 100-110 degrees C to hydrolyze for 1-2 hours, generating amino acid, adding lime to neutralize to pH value to 6.0-6.8, adding carboxymethyl cellulose, at last adding zinc sulfate, copper sulfate, boric acid to dissolve, at 90-105 degrees C to react for 5-6 hours, generating amino acid chelate as a fertilizer solution; compost fermentation: taking the dregs, traditional Chinese medicine dregs, adding water, mixing uniformly, piling and fermenting, 5-10 days turning stack a sequence, and the fermentation time is 30-40 days, lots of white hypha in the stack to obtain completely fermenting the organic fertilizer; taking urea, calcium superphosphate, potassium chloride, and inorganic slow release composition, soil composition of weathered coal, smashing, passing by 100-200 items sieve to obtain nitrogen-phosphorus-potassium fertilizer; completely fermenting the organic fertilizer and mixing nitrogen phosphorus-potassium fertilizer and heterophylla powder, glutin, and nanometer calcium carbonate powder, then spraying amino acid chelate, a fertilizer solution to granulate, at last spraying holly oil to obtain a late rice base special fertilizer.
