Abstract

The invention discloses a preparation method of a fertilizer containing sisal residues, and belongs to the field of fertilizer preparation. The preparation method of the fertilizer comprises the following steps of (1) dewatering and crushing of sisal; (2) mixing and stirring; (3) secondary mixing and stirring; (4) fermenting and drying; (5) cooling and granulating. The fertilizer is prepared from the following raw materials of sisal residues, biogas, urea, sodium humate, potassium sulfate, citric acid, ammonium borate, a fermenting bacterial agent and water. The preparation method has the advantages that by reasonably selecting the components and proper proportional ratio of the fertilizer, the efficiency is high, the pollution is avoided, and the labor cost is reduced.

Description

technical field [0001] The invention belongs to the field of fertilizer preparation, in particular to a fertilizer containing sisal residue and a preparation method thereof. Background technique [0002] Sisal is the main economic crop for hard fiber production in Guangxi, Guangdong. Since the fiber content in sisal leaves only accounts for 3% to 5% of its own, a large amount of waste will be generated during the processing of sisal fibers, such as hemp dregs and hemp juice produced after the fibers are extracted; Hemp bran, hemp heads, etc. produced during processing. These wastes are rich in organic matter such as polysaccharides, pectin, chlorophyll, and cellulose. If they are directly discharged or piled up, it will not only cause a lot of waste of resources, but also cause serious pollution to the environment. The traditional sisal industry only uses sisal fiber, and a large amount of hemp dregs produced during the processing process are used as organic fertilizers. T...
