Amino acid guniting compound fertilizer and preparation method thereof

Abstract

The invention belongs to the field of agricultural fertilizer, and discloses an amino acid guniting compound fertilizer. A preparation method thereof comprises the following steps of: preparation of slurry, mixing of diluted acid, amino acid guniting and granulation, and the like. The invention also discloses a preparation method for the amino acid guniting compound fertilizer. Amino acid is adopted for reaction so as to release a large amount of heat, so that the energy consumption can be effectively lowered. The output of the crops can be effectively improved by utilizing the compound fertilizer, and the compound fertilizer has good nitrogen fixation and water conservation effects.

Description

technical field [0001] The invention belongs to the technical field of agricultural fertilizers, and in particular relates to an amino acid spraying compound fertilizer and a preparation method thereof. Background technique [0002] my country is a large agricultural country. At present, the amount of chemical fertilizer used is as high as 50 million tons per year, accounting for more than a quarter of the global fertilizer use, ranking first in the world. However, because people blindly use a large amount of nitrogen, phosphorus and potassium fertilizers in traditional fertilizers, the nutrients in the soil accumulate, resulting in waste of fertilizers and serious environmental problems. According to reports, the utilization rate of nitrogen fertilizer in my country is less than 50%, the utilization rate of phosphorus fertilizer is less than 20%, and the utilization rate of potassium fertilizer is less than 60%. The release of nutrients from the soil and the absorption of n...
