NOVELTY - Organic-inorganic compound fertilizer comprises sucking and releasing fertilizer matrix material, matrix material preserving fertility, hydrophilic matrix material, hydrophilic organic fertilizer, macroelement fertilizer and inorganic compound. Sucking and releasing fertilizer matrix material is prepared by mixing 1 part carbonized wood residue powder and 6-10 parts expand perlite at 60-65 degrees C for 10-15 minutes and cooled. Carbonized wood residue powder is obtained after passing by 400 items sieve and expand perlite is obtained by baking at 1000-1300 degrees C.    USE - Organic-inorganic compound fertilizer used for planting soybean (claimed).    ADVANTAGE - The organic-inorganic compound fertilizer is economic, increase soybean yield and quality by 14-19%, and dry substance accumulation quantity, reduces fertilizer loss, and promotes healthy grow.    DETAILED DESCRIPTION - Organic-inorganic compound fertilizer comprises sucking and releasing fertilizer matrix material, matrix material preserving fertility, hydrophilic matrix material, hydrophilic organic fertilizer, macroelement fertilizer and inorganic compound. Sucking and releasing fertilizer matrix material is prepared by mixing 1 part carbonized wood residue powder and 6-10 parts expand perlite at 60-65 degrees C for 10-15 minutes and cooled. Carbonized wood residue powder is obtained after passing by 400 items sieve and expand perlite is obtained by baking at 1000-1300 degrees C. Matrix material preserving fertility is prepared by mixing 1 part starch and 45-55 parts clay powder and stirred uniformly. Clay powder is obtained by drying and milling through 200 meshes sieve. Hydrophilic matrix material is prepared by mixing soybean plant straw, plant root and soil and grinding by 100 sieves, and then 1 pts. wt. fermentation powder, 9-11 pts. wt. soybean straw powder and 45-55 pts. wt. animal excrement. Mixture is placed in compost chamber and fermented and decomposed for 40-45 days. Fermented powder is prepared by mixing 10 parts water with 100 parts sucrose boundary at 60 degrees C, and then 50 parts rice bran, 50 parts tea oil and 39 parts bean and 1 part yeast powder. Organic-inorganic compound fertilizer is prepared by mixing 1 part matrix material preserving fertility and 1 part hydrophilic matrix material and maintain nitrogen, phosphorus and potassium elements by adding nitrogen fertilizer, phosphate fertilizer and potassium fertilizer. Inorganic fertilizer is mixed in the product, and then granulated.
