| 摘 要： | 研究不同施肥处理对农田黑土纤维素酶、过氧化物酶和多酚氧化物酶活性的影响。结果表明,不同施肥处理下0~20 cm土壤纤维素酶活性、过氧化物酶活性有机肥与化肥配施(NPK+M)休闲地(FW)单施化肥(NPK)不施肥(CK),21~40 cm土壤NPK+MNPKFWCK处理;多酚氧化酶的活性0~20 cm为FWNPKNPK+MCK处理,21~40 cm为CKFWNPKNPK+M处理。在玉米的生育期内,土壤纤维素酶和多酚氧化酶的活性在出苗后50 d(拔节期)达最大;过氧化物酶的活性在出苗后15 d(苗期)最大。施肥有利于提高土壤纤维素酶、过氧化物酶和多酚氧化酶的活性,有机无机肥配合施用效果最佳。

| Abstract: | The effects of different fertilizer treatments on soil cellulase, peroxidase and polyphenol oxidase activity in response were studied. The results showed that, in different fertilizations, the soil cellulase activity in different periods of maize growth showed the same rule in the 0-20 cm layer and 21-40 cm layer, that was NPK+M > FW > NPK > CK. The soil peroxidase activity showed the same rule, that was NPK+M > NPK > FW > CK. And in the 0-20 cm layer, the soil polyphenol oxidase activity showed as FW > NPK > NPK+M > CK, in the 21-40 cm layer, that was CK > FW > NPK > NPK+M. In crop reproductive period, cellulase and polyphenol oxidase were the most active in the elongation stage (50 days). Peroxidase was the most active in seedling stage (15 days). Fertilization was beneficial to improve the activity of soil cellulase, peroxidase and polyphenol oxidase. In different fertilizer treatments, it was good to coordinate organic fertilizers with inorganic fertilizers. |
