英文摘要	Based on the variations of total humus, humic acid (HA), and fulvic acid (FA) during the manure composting process, the transformation of substances in humus was analyzed, and the compost maturity indexes were constructed by using the TC-TN ratio (C/N), ratio of total humus and total organic carbon (TOC), and humification index (HI). The results showed that: (1) The total humus content in the compost heap decreased firstly and then increased. When compost finished, the total humus content of R1, R2, and R3 was 8.33 +/- 0.31, 7.56 +/- 0.21, and 7.14 +/- 0.35%, respectively; (2) The changes of humic acid (HA) and fulvic acid (FA) concentrations in the three kinds of manure were basically consistent with the changes in total humic acid, which decreased first and then increased; (3) When experiments finished, the ratio of total humus and TOC decreased firstly and then increased. At the end of day 30, HI index was 1.25, 1.15, and 1.01, respectively, increasing by 48.8, 45.56, and 31.16%, respectively.
