Chicken manure and rice straw were composted together in windrow to study the effect of C/N on humus in composting. The results showed that C/N of the substrate had no significant influence on production of fulvic acid. C/N between 20～35 was in favor of production of total humus and soluble humus. C/N between 20～30 was in favor of production of free humus and humo acid. At C/N of 30, the most amount of total humus was produced.%以鸡粪、稻草为原料,采用条垛式高温堆肥,研究C/N对堆肥腐殖酸的影响.结果表明,C/N对富里酸生成无显著影响;C/N在20～35间有利于总腐殖酸和水溶性腐殖酸的形成;C/N在20～30间有利于游离腐殖酸和胡敏酸的生成;C/N为30,堆肥腐熟后总腐殖酸生成量最多.
