AI Technical Summary
Technical Problem
Existing methods to reduce methane generation in paddy fields by extending the mid-drying period have adverse effects on rice growth and yield, necessitating a more efficient methane reduction method that does not extend this period.
Method used
A methane emission reduction device comprising a boat body with a propulsion system, soil working unit, and oxygen supply unit that operates unmanned on the water surface, agitates the soil, and supplies oxygen to reduce methane generation through anaerobic fermentation.
Benefits of technology
The device effectively reduces methane generation without extending the mid-drying period, minimizing labor and rice yield impact while efficiently covering large areas.
