Sustainable agriculture aims to achieve the coordinated development of ecology, economy and society, emphasizing the protection of the ecological environment and the reduction of resource consumption and pollution emissions while ensuring food security and increasing farmers' income. In our country, sustainable development agriculture has been strongly supported by national policy and has obtained remarkable results. However, there are still problems such as excessive use of chemical fertilizer and soil pollution in agricultural production, and effective measures need to be taken to improve them.

Organic fertilizer production lines play an important role in the green revolution, which can improve agricultural production efficiency, reduce environmental pollution, and promote sustainable agricultural development. Organic fertilizer equipment converts agricultural waste into organic fertilizer, which is conducive to improving soil fertility, reducing fertilizer use, and reducing agricultural production costs. At the same time, the organic fertilizer production line can also reduce the pollution of agricultural waste to the environment and improve the ecological environment.

In short, organic fertilizer production lines play an important role in sustainable agriculture. China should continue to increase the policy support for organic fertilizer production lines and technological innovation, promote the green revolution, and achieve sustainable development of agriculture.
