Method for preparing fertilizer

Abstract

The invention discloses a method for preparing a fertilizer. Cow dung serves as a raw material, the specific preparation processes comprise the following steps that (1) the cow dung is placed in a stirrer, solution is added, then stirring, smashing and dry-wet splitting are carried out to obtain a granular fertilizer and a waste liquid; (2) bran shells, fungi residues and vinasse are mixed into the granular fertilizer for fermentation to obtain a fruit tree fertilizer; (3) lime water is mixed in the water liquid for sterilization; earthworm, chicken or fish feed is obtained; according to the method for preparing the fertilizer, the cow dung is utilized as the raw material to prepare the multipurpose original-ecology fertilizer with no feed additives, good quality and low cost.

Description

technical field [0001] The invention belongs to the technical field of mixtures of one or more fertilizers and components without special fertilizer effects, and in particular relates to a preparation method of fertilizers.

[0002] Agriculture is the foundation of other industries such as industry and service industry. The rise and fall of agriculture is a major event that directly affects the national economy and people's livelihood. At present, the world is facing serious problems of population increase and environmental degradation. As a country with a large population and a large agricultural country, this problem is especially One of the main reasons for this situation is the extensive use of inorganic fertilizers. The deficiencies of this inorganic fertilizer are mainly manifested in the following aspects: 1. The nutrient is single, and it cannot provide comprehensive and reasonable nutrients for crops;

[0003] 2. After use, the soil will become acid-alkali or salinized, which will reduce the soil quality; 3. Due to the decline in soil quality, the buffer capacity will be greatly reduced, and the use of inorganic fertilizers will be difficult to achieve results and easily cause fertilizer damage; 5. The production and use of inorganic fertilizers will cause a lot of pollution to the environment and waste a lot of resources;

[0004] 6. Make agricultural production fall into a vicious circle, making it difficult to achieve sustainable development
