The invention discloses a method for producing composite fertilizer for sugarcanes through waste residues of sisal hemp. The composite fertilizer is produced from the following raw materials in parts by weight: 50-100 parts of the waste residues of the sisal hemp, 1-6 parts of strain, 8-10 parts of filtration mud, 30-50 parts of inorganic fertilizer, 1-3 parts of secondary elements, 0.3-0.5 part of micro elements and 10-12 parts of waste liquid of alcohol. The method comprises the following steps: firstly, filtering the waste residues of the sisal hemp, adding the strain and the filtration mud in parts by weight, and putting the mixture in a fermenting room for fermentation; controlling the temperature of the fermenting room to be 50-60 DEG C, and fermenting for 8-20 days to obtain a fermented feed; then drying the obtained fermented feed, adding the inorganic fertilizer, the secondary elements and the micro elements in parts by weight, crushing the mixture of the dried fermented feed, the inorganic fertilizer, the secondary elements and the micro elements through a crushing machine, adding the waste liquid of the alcohol in parts by weight as a binder for pelleting through a rotary drum pelleting method, and screening granules; and after the screened granules are inspected to be qualified, measuring and packaging the qualified granules. The composite fertilizer for the sugarcanes has the obvious effect of increasing production, and has the effects of reducing environmental pollution, improving soil, improving the quality of crops, reducing the using amount of chemical fertilizer.
