I want a straw machine, a wheat packing machine, a paper bag for processing power plants and paper mills
And what kind of machine is suitable for processing?. I don't know your local straw variety, so I can't answer you directly.
Subsidies, manufacturers, models, they know more about the local straw
With subsidies, you have to go to the local, especially in the construction of biomass power plants to consult, they will actively tell you about the machine prices
