2. Improper operation of workers. In the production process, the worker's operational proficiency and accuracy have a great impact on the production efficiency. Due to the lack of relevant experience, some workers are not skilled in operation, resulting in frequent errors in the production process, which affects the production schedule.

3. Raw material supply problem. The supply of raw materials required for organic fertilizer production lines is insufficient, and the quality of pig manure supplied is unstable, which will also affect production efficiency. The dry humidity, size, cleanliness of pig manure will affect the operation of the equipment, if these factors are not effectively controlled, it will affect the production line capacity.

4, the production plan is not reasonable. In the production process, if the production plan is not reasonable, it will cause the production line to work too much or too little in a certain period of time, and then affect the production efficiency.

In summary, the main reasons for the decline in the efficiency of the pig manure organic fertilizer production line are aging equipment, improper operation of workers, raw material supply problems and unreasonable production plans. In response to these problems, we need to take timely measures to improve the production environment, improve workers' skills, strengthen raw material management, and optimize production plans to improve production efficiency.
