NOVELTY - System comprises cutting unit, fermentation unit, intelligent control unit, waste heat recovery unit, press filtration unit, grinding and crushing unit, blending unit, granulation and drying unit and a finished product sub-packaging unit, where the fermentation unit comprises fermentation tank, biogas recovery unit, heating unit, heat exchange unit, sprinkling unit, automatic feeding unit and stirring unit. The control unit includes sensor and intelligent control chip. The fermentation tank has cavity straw for sensor.    USE - The system is useful for synthesizing quick-acting and slow-release integrated efficient ecological fertilizer through straw microbial fermentation (claimed).    ADVANTAGE - The system promotes biological degradation and decomposition of the straws, accelerates degradation of the straws and shortens fermentation period.    DETAILED DESCRIPTION - System comprises cutting unit, fermentation unit, intelligent control unit, waste heat recovery unit, press filtration unit, grinding and crushing unit, blending unit, granulation and drying unit and a finished product sub-packaging unit, where the fermentation unit comprises fermentation tank, biogas recovery unit, heating unit, heat exchange unit, sprinkling unit, automatic feeding unit and stirring unit. The control unit includes sensor and intelligent control chip. The fermentation tank has cavity straw for sensor. The stirring unit is provided in cavity of the tank. The heating unit is provided for heating cavity. The heating is controlled by the intelligent control unit. The heat exchange unit is provided for exchanging heat and collecting cavity of excess straw produced by fermentation. The fermentation tank is provided with feed inlet and methane collection port. The intake port is provided above the feed unit and automatic feeding spraying unit. The fermentation liquid discharge port is communicated collection tank. The pressure filtration unit is provided for fermented product after fermentation water filter press. The waste heat recovery unit is provided for collecting heat from heat exchange unit. An INDEPENDENT CLAIM is included for method for synthesizing quick-acting and slow-release integrated efficient ecological compound fertilizer through straw microbial fermentation, which involves performing sealed fermentation on straws and animal feces, performing water press filtration on a fermentation product, then performing high-temperature inactivation, adding inorganic quick-acting fertilizer and trace element fertilizer, rooting powder, a drought-resistant water retention agent and clay, mixing, and performing granulation and drying to obtain fertilizer.
