introduction

fertilizer is of great significance for agricultural production, can improve the yield and quality of crops. With the continuous development of agricultural technology, the demand for fertilizers is also increasing. Therefore, it is of great significance to study the manufacturing method of fertilizer and improve the efficiency and quality of fertilizer production for promoting agricultural development. The basic concept and function of

1. fertilizer

fertilizer refers to the material that can supply plant nutrients, promote plant growth and improve soil properties. The main functions of fertilizers include increasing plant nutrient content, improving soil physical and chemical properties, promoting soil microbial activity, and improving soil fertility.

2. fertilizer manufacturing methods

1. physical method

physical method is mainly through the physical processing of raw materials into fertilizer. Common physical methods include grinding, sieving, mixing, etc. The physical method has the advantages of simple process, low cost and no pollution, but the product quality is low and the nutrient content is uneven.

2. Chemical method

Chemical method is the method of converting raw materials into fertilizer through chemical reaction. Common chemical methods include acidolysis, alkaline hydrolysis, redox, etc. Chemical method has the advantages of high product quality and uniform nutrient content, but the process is complex, high cost and easy to produce pollution.

3. biological method

biological method is a method of converting raw materials into fertilizer through microbial fermentation, enzymatic hydrolysis and other biological technologies. The biological method has the advantages of environmental protection, energy saving and high product quality, but the process requirements are high and specific equipment and conditions are required. The comparison and evaluation
of different manufacturing methods of

physical method, chemical method and biological method have their own advantages and disadvantages, and the suitable manufacturing method should be selected according to the specific situation. The physical method is suitable for situations where the quality of raw materials is good and the product quality is not high; the chemical method is suitable for situations where high-quality products are required, but factors such as environmental protection and cost need to be considered; the biological method has the advantages of environmental protection and energy saving, but requires specific The scope of application of equipment and conditions is relatively narrow.

4. research status and development trend

At present, the research of fertilizer manufacturing methods mainly focuses on improving product quality, reducing costs, reducing pollution and so on. In the future, with the improvement of environmental awareness and the continuous development of technology, biological and new physical and chemical methods will become research hotspots, and fertilizer manufacturing will develop in the direction of more efficient, environmentally friendly and energy saving.

conclusion The study of

fertilizer manufacturing methods is of great significance for improving fertilizer production efficiency and quality. Different manufacturing methods have their own advantages and disadvantages, and the appropriate method should be selected according to the specific situation. In the future, with the continuous development of technology, fertilizer manufacturing will be more efficient, environmentally friendly, energy-saving direction.
