Takai，Koyama，and Kamura（1，2，3，4，5，6），Koyama（7，8，9，10，11，12）等研究了淹水水稻土还原过程中的微生物代谢。结果表明，淹水土壤微生物代谢过程按以下步骤进行：（1）在培养初期，溶解氧消耗，氧化还原电位迅速下降; (2)NO2−和NO2−被还原为N2。(3)Mn 4+被还原成Mn 2+。(4)Fe 3+被还原为Fe 2+。(5)SO 4 2−被还原为S2−。(6)生成H2和CH 4。Takai和Chiang（13）报道，淹水水稻土中的NH 4+和PO 43+随着培养期的延长而增加。Chiang和Takai（14）指出，土壤溶液中的碳水化合物在整个孵育期间几乎保持不变，然而，有机酸的变化与之前报道的相似（5，6）。
Abstract Microbial metabolism in reduction process of waterlogged paddy soils has been studied by Takai, Koyama, and Kamura (1, 2, 3, 4, 5, 6), Koyama (7, 8, 9, 10, 11, 12), and others. The results indicated that microbial metabolism in waterlogged soils takes place according to the following steps: (1) In the early stage of the incubation period, dissolved O2, is consumed and the redox potential drops rapidly. (2) NO2− and NO2− are reduced to N2. (3) Mn4+ is reduced to Mn2+. (4) Fe3+ is reduced to Fe2+. (5) SO4 2− is reduced to S2−. (6) H2 and CH4 are produced. Takai and Chiang (13) reported that NH4+ and PO4 3+ in waterlogged paddy soils increase with the incubation period. Chiang and Takai (14) indicated that carbohydrates in the soil solutions almost remain constant throughout the incubation period, however, organic acids change similarly to those reported previously (5, 6).
