Abstract

The invention belongs to the fertilizer and the production method thereof, which relates to organic controlled-release fertilizer produced by the propylhomoserin method. The organic controlled-release fertilizer is composed of waste residue of sodium glutamate, crop stalk, inorganic NPK raw material fertilizer, composite microbial agent, sulfuric acid and liquid ammonia. The composite microbial agent comprises 15 percent of photosynthetic bacteria, 5 percent of ray fungi, 10 percent of saccharomycete, 20 percent of P-releasing bacteria, 20 percent of K-releasing bacteria and 30 percent of azotobacteria. The waste residue of sodium glutamate, the crop stalk and nutshell in the proportion are mixed, and composted and fermented by adding the composite microbial agent, the inorganic NPK raw material fertilizer is added, then the liquid ammonia and the sulfuric acid are added, and the organic controlled-release fertilizer is produced through granulation, drying, cooling and screening. The organic controlled-release fertilizer has the advantages that the nitrogen, the phosphorus and the potassium can be released slowly; the content of the organic matter is high; the content of the nitrogen, the phosphorus and the potassium can be regulated according to the need; the production cost of the fertilizer can be reduced.

Description

technical field [0001] The invention belongs to a fertilizer for agricultural production, in particular to an organic controlled-release fertilizer produced by an acid method capable of slowly releasing nitrogen, phosphorus and potassium in the fertilizer. Background technique [0002] 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 yield. 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, which is conducive 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 kinds of various organic and inorganic mixed fe...
