Fermented fertilizer added with chitin and preparation method of fermented fertilizer

Abstract

The invention discloses a fermented fertilizer added with chitin and a preparation method of the fermented fertilizer. The fertilizer is characterized by being prepared from the following raw materials in parts by weight: 300-500 parts of sheep manure, 200-250 parts of straw powder, 60-80 parts of urea, 55-65 parts of a phosphatic fertilizer, 55-65 parts of potassium chloride, 10-25 parts of chitin, 10-15 parts of diluted phosphoric acid, 5-7 parts of quintozene, 35-45 parts of potassium sulfate, 30-35 parts of diammonium phosphate, 20-25 parts of magnesium sulfate and 7-9 parts of a soil activator. A soil improver contains a jade component which contains a lot of trace elements beneficial to a human body. Meanwhile, toxic heavy metal elements can be effectively adsorbed and solidified, the amount of heavy metal elements adsorbed by crops is reduced, and the crop yield can be improved. The chitin fertilizer, taking both consideration to insecticides and bactericides, is mixed with an organic fertilizer in use so as to fully exert the characteristics of biodegradability and compatibility, thereby playing a synergic role to pesticides and chemical fertilizers.

Description

technical field [0001] The invention relates to a fermented fertilizer, in particular to a fermented fertilizer added with chitin and a preparation method thereof. Background technique [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 severe problems of population increase and environmental degradation. As a country with a large population and a large agricultural country, this problem is particularly prominent. 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 cannot provide comprehensive and reasonable nutrients for crops; 2. After use, the soil will be acidified or salinized, which will reduce the soil quality; 3. ...

AI Technical Summary

Problems solved by technology

The deficiencies of this inorganic fertilizer are mainly manifested in the following aspects: 1. The nutrient is single and cannot provide comprehensive and reasonable nutrients for crops; 2. After use, the soil will be acidified or salinized, which will reduce the soil quality; 3. 1. Due to the decline of soil quality, the buffering capacity is greatly reduced, and the use of inorganic fertilizers is difficult to achieve results and is likely to cause fertilizer damage; 4. Due to the imbalance of nutrients, the disease resistance of the crops used is reduced; 5. During the production and use of inorganic fertilizers, there will be The environment causes a lot of pollution and wastes a lot of resources; 6. It makes agricultural production fall into a vicious circle and it is difficult to achieve sustainable development
