The nature and use
of compound fertilizer
compound fertilizer is a kind of chemical fertilizer containing two or more nutrients (such as nitrogen, phosphorus, potassium, etc.), which plays an important role in promoting plant growth and improving crop yield and quality. In the field of raw materials for chemical production, the properties and uses of compound fertilizers have attracted much attention. This article will detail the properties of compound fertilizer, production methods and applications in different fields.

1. The properties of compound fertilizer

1. Physical properties: Compound fertilizer is usually granular or powdery, with various colors, hygroscopic, and soluble in water.
2. Chemical properties: The nutrient elements in the compound fertilizer exist in the form of compounds, which have high stability and are not easy to volatilize, lose or be fixed by the soil. The pH of compound fertilizer varies from product type to product type, generally neutral or slightly acidic.

2. compound fertilizer production methods

compound fertilizer production methods mainly include physical mixing method, chemical synthesis method and biological fermentation method. Among them, the physical mixing method is to mix the compounds of different nutrient elements according to a certain proportion; the chemical synthesis method is to combine different nutrient elements through chemical reactions; the biological fermentation method is to use microbial fermentation to produce compound fertilizer.

3. the use of compound fertilizer

compound fertilizer in agriculture, forestry, horticulture and other fields are widely used, the following are introduced its use:

1. agriculture: compound fertilizer can improve soil fertility, promote crop growth, improve yield and quality. Different types of compound fertilizers can be formulated according to the growth needs of crops to meet the needs of different crops for nutrients.
2. Forestry: Compound fertilizer can promote tree growth and improve wood quality and yield. At the same time, the rational application of compound fertilizer can also improve the forest soil environment and contribute to the ecological balance of the forest.
3. Horticultural field: compound fertilizer can promote the growth of flowers, fruit trees, vegetables, etc., improve the nutritional status of plants, and improve the ornamental value and edible quality. The development trend of

4. compound fertilizer

With the continuous progress of science and technology, the development of compound fertilizer shows the following trends:

1. high efficiency: the new compound fertilizer has higher nutrient content and better absorption and utilization rate, which can improve the yield and quality of crops.
2. Environmental protection: With the improvement of people's awareness of environmental protection, the production and use of compound fertilizers pay more attention to environmental protection and reduce environmental pollution.
3. multi-functional: compound fertilizer in addition to providing nutrients, but also improve the soil, improve plant resistance and other multi-functional role.

5. conclusion

compound fertilizer as an important raw material for chemical production has been widely used in agriculture, forestry, horticulture and other fields. Understanding the properties of compound fertilizer, production methods and its application in different fields is of great significance for improving crop yield and quality and promoting ecological balance. With the continuous progress of science and technology, compound fertilizer will develop in the direction of high efficiency, environmental protection and multi-function, and make greater contributions to the development and progress of human society.
