ORGANIC COMPOSITE FERTILIZER FOR AQUATIC RICE USING NATURAL MINERALS AND MICROBES AND MANUFACTURE THEREOF

摘要

PURPOSE: Provided is an organic fertilizer which improves the yield of rice and reduces the use of chemical fertilizer by mixing oil cake mixture, siliceous powder and liquid byproduct from molasses fermentation, and soil microbes. CONSTITUTION: The organic fertilizer is manufactured by mixing 10-20wt.% of solid culture microbes with 80-90wt.% of organic mixture composition comprising 65-75wt.% of oil cake mixture, 10-20wt.% of mineral coating powder and 5-15wt.% of langbeinite. The oil cake mixture contains 35-40wt.% of caster oil cake, 15-20wt.% of soybean oil cake, 10-15wt.% of rice bran oil cake and 30-35wt.% of seed oil cake. The mineral coating powder with 15wt.% of moisture content is obtained by 50wt.% of siliceous powder and 50wt.% of liquid byproduct from molasses fermentation, and drying. The solid culture microbes are obtained by mixing soil microbes with 50-60wt.% of rice bran, 5-15wt.% of zeolite, 15-25wt.% of soybean meal, 20-30wt.% of wheat residue and 5-15wt.% of fish powder, and culturing.
