technical field

[0001] The invention relates to a crop fertilizer, in particular to a refined bio-organic fertilizer produced by using livestock manure and monosodium glutamate residue and a preparation method thereof. Background technique

[0002] With the continuous improvement of people's living standards, the demand for safe food such as pollution-free, green and organic food is also increasing. According to the forecast of authoritative experts, the global organic food market sales will increase from the current 10 billion US dollars to 100 billion US dollars in the next ten years. Organic food will become the leading food in the 21st century. However, the types of special fertilizers for producing organic food are still limited, which cannot meet the needs of the vigorous development of organic agricultural products. Therefore, the use of waste such as livestock and poultry manure to produce high-quality organic fertilizer is of great significance to promote the deve...
