Abstract

The invention belongs to the technical field of fertilizers, and particularly relates to a method for producing a sugarcane carbon-based slow-release fertilizer by carbonization of filter mud in a sugar refinery, the sugarcane carbon-based slow-release fertilizer is mainly prepared from the following raw materials by weight: 40-50 parts of the filter mud, 45-55 parts of alcohol waste liquid, 15 to20 parts of urea, 10 to 15 parts of potassium sulfate, 8 to 12 parts of calcium superphosphate, 0.12 to 0.18 part of Azotobacter chroococcum, 0.15 to 0.35 part of Bacillus subtilis, 0.45-0.64 part ofbacillus mucilaginosus, 0.25-0.46 part of Bacillus lentus, 0.15-0.37 part of Pseudomonas caryophylli, 2-4 parts of lignin, 1-3 parts of vegetable oil, 0.2 to 0.5 part of sulfuric acid, 2 to 3 parts of Xanthomonas campestris pv. campestris gum and 1 to 3 parts of curdlan. The method comprises preparing of fertilizer core particles, preparing of a coating and coating. The method solves the problemsof low utilization rate of fertilizers in the prior art and difficulty in degradation of a coating agent material in slow release fertilizers.

Description

【Technical Field】 [0001] The invention belongs to the technical field of fertilizers, and specifically relates to a method for preparing sugarcane carbon-based slow-release fertilizer by peatization in a sugar factory. 【Background technique】 [0002] The nitrogen, phosphorus, and potassium fertilizers used in agricultural production are quick-acting fertilizers, which play a very important role in promoting crop growth and increasing crop yields. Various organic fertilizers play an important role in improving soil, increasing soil organic matter, increasing crop yield, and improving crop quality. Since the fertilizer effect of organic fertilizers is slowly released in the soil, it is beneficial to the balanced growth of crops. People add inorganic nitrogen, phosphorus, and potassium fertilizers to organic fertilizers to produce organic and inorganic mixed fertilizers. At present, there are many varieties of organic and inorganic fertilizers, and they are widely used. However, an...
