NOVELTY - Aerobic fermentation comprises uniformly mixing crushed crop straw and livestock manure at weight ratio of 2:1, high-temperature fermenting, and aerobically fermenting. Fermentation is performed using an aerobic fermentation device comprising fermentation chamber(s) (1), drain holes (3) connected to a drainage ditch (4), horizontal ventilation pipes (5), vertical ventilation pipes (6), and blower (7).    USE - Method for aerobic fermentation (claimed).    ADVANTAGE - The method is suitable not only for small and medium-size farms, but also for large-scale farm operating cycle and continuous production cycle; has good fermentation speed and quality; and high overall efficiency.    DETAILED DESCRIPTION - Aerobic fermentation comprises uniformly mixing crushed crop straw and livestock manure at weight ratio of 2:1, high-temperature fermenting, and aerobically fermenting. Fermentation is performed using an aerobic fermentation device including fermentation chamber(s) (1) having three sidewalls with height of 200 cm, width of 100-300 cm and length of greater than or equal to 300 cm; and an open side provided with a plug-in board. Drain holes (3) are provided on lower left side of the sidewall and connected to a drainage ditch (4) which is 100 cm away from the drain holes. At least one group of ventilation pipes comprising horizontal ventilation pipes (5) and vertical ventilation pipes (6) is provided in the fermentation device. The horizontal ventilation pipes and sidewalls are arranged parallel on the ground. One end of horizontal pipes extends outside the fermentation device and is connected with a blower (7). Each horizontal ventilation pipe has length of 100 cm. One end of horizontal pipe is connected with vertical pipe through an elbow (8). A three-way connecting pipe (9) connects two horizontal pipes and one vertical pipe. Each vertical ventilation pipe has length of 200 cm. The horizontal and vertical ventilation pipes are provided with four rows of 0.5-cm holes. Each row adjacent hole center distance is 10 cm. Adjacent line hole position is 5 cm apart.
