The development of organic fertilizer production lines has gone through several key stages, mainly driven by the awareness of sustainable agricultural development and environmental protection:

1. Initial stage: In the context of increasing environmental awareness, people began to pay attention to the negative impact of chemical fertilizers on the soil and the environment, and also realized the potential of organic agriculture. Organic fertilizer production was initially small-scale and manual, relying mainly on traditional composting and fermentation techniques.

2. Technological improvement and automation: With the progress of science and technology and the needs of industrial production, organic fertilizer production has gradually introduced more advanced production processes and organic fertilizer equipment.

3. Large-scale production: With the popularity of organic agriculture and the increase in market demand, organic fertilizer production has begun to develop in the direction of large-scale and industrialization. The construction and optimization of production lines make it possible to produce on a large scale to meet the needs of different regions and different crops.

4. Standardization and quality control: The production of organic fertilizer has gradually introduced strict quality control and standardized management system to ensure that products meet the requirements of organic certification. This includes the audit of the source of raw materials, the monitoring of the production process, and the testing of product quality, which improves the market competitiveness and consumer trust.

5. Innovation and research and development: In recent years, with the development of agricultural science and technology, organic fertilizer production lines are also constantly innovating and developing. For example, the use of new technologies such as microbial fermentation technology and biodegradation technology has improved the benefits and environmental performance of organic fertilizers, providing new possibilities for future sustainable agricultural development.
