【摘要】 对玉米植株残体腐解过程中元素和物质组成的变化进行了化学分析。结果表明 :玉米植株各部分残体元素含量和化学组成及其在腐解中的变化是有差异的。但大部分的碳水化合物和脂肪族化合物氧化为CO2 和H2 O而损失掉。N肥的加入促进了有机残体的腐解过程更多还原

【Abstract】 The chemical elements and constitutes of corn plant residues (CPR) were analysed during its decomposing process. Differences were found among different parts of corn plant in the contents of elements, chemical constitutes and their changes during decomposition. With the progress of CPR, most carbohydrates and aliphatic compounds were oxidized into CO 2 and H 2O. The addition of N fertilizer promoted the decomposition process of CPR.更多还原
