Based on the long-term fixed position experimental data from Qianyanzhou Ecological Experiment Station, Chinese Academy of Sciences in 1998, this paper analyzed the effects of applying different kind fertilizers (straw, ST; pig manure, OM; and chemical fertilizer, NPK) on the nutrients (C, N, and P) status and the activities of related enzymes (β-1,4-glucosidase, βG; β-1,4- N-acetylglucosaminidase, NAG; L-leucine aminopeptidase, LAP; and acid phosphatase, AP) in reddish paddy soil. With the application of OM, the activities of soil βG, NAG, and LAP increased significantly, as compared with other treatments, and were 1. 4, 2. 6, and 1. 9 times higher than the control (CK), respectively. Applying OM also improved the ratio of soil organic carbon to total nitrogen (C/ N), but decreased the soil βG/ (NAG+LAP) ratio, suggesting that pig manure could benefit the degradation of soil cellulose and the accumulation of soil organic carbon. Applying NPK increased the activities of soil βG, NAG, and LAP, but decreased the AP activity, with a decrement of 34% as compared with CK. Under the application of NPK, the soil βG/ AP and (NAG+ LAP) / AP ratios increased, but the ratios of soil organic carbon to total phosphorus (C/ P) and of soil total nitrogen to total phosphorus (N/ P) decreased, indicating that chemical fertilizers could induce the accumulation of soil inorganic phosphorus, and inhibit the microbial functions of degrading polysaccharides and phosphate phospholipids.
