Abstract:This research proved that a thermal analysis could be used to study the plant residue decaying.Variations in pyrolytic features of corn residues in the decaying process was investigated under field conditions.The results show that 280℃,330℃,and 450℃ peaks of DTA curve and the second peak of DTG curve could be regarded as the featured peak" and the ratio of h 330℃ / h 450℃ as \"the featured index".Energy parameters( ΔΗ,E )brought out such two stages as the fluctuating\|rolling stage and th...
