With the sustainable development of China's agriculture, organic fertilizer production line plays a more and more important role in modern agriculture. At present, organic fertilizer production lines have made significant progress in terms of technology, automation, policy support and social and environmental benefits, providing a strong guarantee for the green growth of China's agriculture.

The present situation and development of organic fertilizer production line show the characteristics of diversification and high efficiency. On the basis of traditional organic fertilizer production, researchers continue to develop new organic fertilizer production lines, such as biological organic fertilizer production lines, decomposed organic fertilizer production lines, etc., to meet the needs of different regions and crops. In addition, organic fertilizer equipment is also constantly upgrading, from the original simple equipment to large-scale, continuous, intelligent direction, improving production efficiency and product quality.

The social and environmental benefits of organic fertilizer production line are remarkable. First of all, the operationalization of organic fertilizer production lines is conducive to improving the comprehensive production capacity of agriculture and promoting the adjustment of agricultural industrial structure. Secondly, the wide application of organic fertilizers helps to improve soil quality, improve crop yield and quality, and ensure national food security. Finally, the development of organic fertilizer production lines is conducive to reducing the use of chemical fertilizers, reducing agricultural production costs, and protecting the agricultural ecological environment.

In short, the development of organic fertilizer production line operability has provided strong support for the green growth of China's agriculture. Under the new historical conditions, organic fertilizer production lines will continue to play an important role in contributing to the realization of sustainable agricultural development.
