Evaluating the technical strength of organic fertilizer production line enterprises can be carried out from the following aspects:

1. Conformity of production technical standards: Check whether enterprises follow the national standards for organic fertilizer production, covering key technical requirements such as technical indicators and limit indicators of organic fertilizer.

2. Mastery of key technologies: Evaluate whether the enterprise has mastered key technologies such as fermentation and granulation, which are the core of the organic fertilizer manufacturing process. In particular, the ability to vaccinate microorganisms, optimize fermentation efficiency and improve product quality.

3. Raw material safety evaluation: whether the enterprise can conduct safety evaluation on the evaluated raw materials. The technical strength of the enterprise is also reflected in its ability to evaluate the risk of raw material safety.

4. Product quality control: Evaluate whether the enterprise has a strict product quality control system, including the control and detection ability of key indicators such as organic matter content, total nutrient content, moisture content, pH value, seed germination index, mechanical impurity content, etc.

5. Technological innovation ability: investigate the investment and achievements of enterprises in the technological innovation of organic fertilizer equipment, including the research and development of new technologies, the optimization of process flow, and the development of new products.

6. Environmental protection and sustainable development practices: Evaluate the performance of enterprises in environmental protection and sustainable development, such as waste treatment, energy consumption, carbon footprint, etc.

7. Professional qualification and certification: Whether the enterprise has relevant professional qualification and certification, such as ISO quality management system certification, environmental protection certification, etc.

Through the comprehensive evaluation of the above aspects, we can fully understand the technical strength of organic fertilizer production line enterprises, and provide references for the technological development of enterprises.
