The organic fertilizer production line plays a significant role in improving the quality of agricultural products, mainly reflected in the following aspects:

Improving soil structure and fertility: The fertilizers produced by organic fertilizer equipment are rich in organic matter and various microorganisms, which can significantly improve the physical, chemical and biological properties of the soil. Organic fertilizers can also enhance the availability of nutrients in the soil, reduce nutrient loss and increase the utilization rate of chemical fertilizers.

2. Enhance the nutritional quality of agricultural products: Organic fertilizers can provide comprehensive and balanced nutrients, promoting the healthy growth of crops and thereby increasing the nutritional content of agricultural products. Organic fertilizers can also improve the taste and flavor of agricultural products.

3. Reduce the residue of harmful substances: Compared with chemical fertilizers, the use of organic fertilizers reduces the input of chemically synthesized substances. The microorganisms in organic fertilizers can decompose harmful substances in the soil, enhance the self-detoxification ability of crops, and further reduce the accumulation of harmful substances in agricultural products.

4. Promoting crop growth and disease resistance: The microorganisms and organic substances in organic fertilizers can promote the growth and development of crop roots, enhancing the crops' disease resistance, drought resistance and waterlogging tolerance.

5. Enhance the market competitiveness of agricultural products: Agricultural products produced with organic fertilizers not only have higher quality but also better meet consumers' demands for green and organic food, thus having greater market competitiveness and added value.

In conclusion, organic fertilizer equipment has significantly enhanced the overall quality of agricultural products through multiple functions such as improving soil structure, enhancing the nutritional quality of agricultural products, reducing the residue of harmful substances, and promoting crop growth, providing strong support for the sustainable development of agriculture.
