The impact of environmental protection policies on organic fertilizer equipment manufacturers is mainly reflected in the following aspects:

1. Technological innovation and development: The promotion of environmental protection policies has made the relevant technical level of organic fertilizer production lines continue to improve, and the number of effective patents is also growing, helping the innovation and development of the organic fertilizer industry.

2. Policy support and subsidies: The summary of policies at the provincial and municipal level shows that the policy direction of major provinces and cities in China mainly starts from two aspects: improving the utilization rate of fertilizer and improving the utilization rate of organic fertilizer. Beijing and Shanghai put forward the subsidy policy for the application of organic fertilizer.

3. Gradual improvement of industry standards: Driven by environmental protection policies, organic fertilizer industry standards have gradually improved, promoting organic fertilizer equipment manufacturers to produce in accordance with higher environmental standards.

4. Industrial upgrading: Environmental protection policies promote the industrial upgrading of organic fertilizers, and manufacturers need to constantly innovate and improve equipment to adapt to changes in policy requirements and market demand.

5. Environmental compensation policy: The policy explores the land compensation policy and environmental compensation policy focusing on straw returning to the field and organic fertilizer application, which provides market opportunities for organic fertilizer equipment manufacturers.

6. Low carbon compensation policy: The policy promotes low carbon compensation policy, encourages the reduction of fertilizer use, increases the application of organic fertilizer, and promotes the development of organic fertilizer equipment manufacturers.

To sum up, environmental protection policies have had a positive impact on organic fertilizer equipment manufacturers, not only promoting the growth of market demand, but also promoting technological innovation and the improvement of industry standards, providing manufacturers with a broad market space and development opportunities.
