Problems solved by technology

[0003] The production of inorganic compound fertilizers by the amino acid method is a new fertilizer production process that has emerged in recent years. Compared with the general compound fertilizer production process, it has many advantages, but at present there are only relevant reports on the production of inorganic compound fertilizers by the acid method
After extensively consulting domestic and foreign publications and retrieving domestic and foreign patent documents, there is no report on the production of organic-inorganic compound fertilizers using the amino acid process; and the technical practice of using the amino acid process to produce organic-inorganic compound fertilizers is also rare in the fertilizer industry.

Abstract

The invention disclose a lignin-containing organic-inorganic compound fertilizer prepared by an ammonia-acid method as well as the ammonia-acid production method. According to the invention, the organic-inorganic compound fertilizer is prepared by using the following components in parts by weight through an ammonia-acid process: 20-30 parts of lignin, 50-60 parts of nitrogen-phosphorus-potassium fertilizer, 0.2-0.5 parts of compound inoculant, 3-5 part of concentrated sulfuric acid, 2.5-3.5 parts of liquid ammonia and 5-15 parts of binding agent; and the raw materials also include 2-4 parts of chelated trace element fertilizer. The organic-inorganic compound fertilizer prepared by the ammonia-acid method uses the lignin as the source of organic material, has a large amount of organic active materials and a large amount of nitrogen, phosphorus and potassium elements, and can satisfy the growth needs of the farm corps completely.

Description

technical field [0001] The invention relates to the technical field of fertilizers for agricultural production, in particular to an organic-inorganic compound fertilizer containing lignin produced by an amino acid method and a method for producing amino acid. Background technique [0002] At present, fertilizers commonly used in agricultural production are divided into inorganic compound fertilizers and organic fertilizers. Inorganic compound fertilizers are quick-acting fertilizers, which play a very important role in promoting crop growth and increasing crop yields. However, the extensive use of inorganic compound fertilizers will destroy the soil structure, lead to secondary salinization, and shorten soil tillage. The life of the layer and the quality of agricultural products are reduced; while organic fertilizers play an important role in improving soil, increasing soil organic matter, and improving crop quality. Since the fertilizer effect of organic fertilizers is rele...
