摘  要：
在蔗地上设计不施肥(CK1)、施化肥(CK2)和4个直接喷施甘蔗酒精废液处理,研究不同用量废液施用对土壤理化性状及两种氧化还原酶活性的影响。结果表明:蔗地施用废液提高了土壤全氮、Cl-、有机质、腐殖质含量,使甘蔗苗期土壤过氧化氢酶和多酚氧化酶活性异常升高,随后迅速下降,成熟期下降到接近或小于CK2的土壤酶活性水平。甘蔗苗期土壤过氧化氢酶活性与全氮、有机质、腐殖质呈极显著正相关,与富里酸、胡敏酸、Cl-呈显著正相关(r0.05=0.811,r0.01=0.917,n=6);土壤多酚氧化酶活性与有机质、腐殖质、Cl-呈显著正相关。与不种植甘蔗的75tCK废液处理相比,种植甘蔗的75t废液处理甘蔗生长后期土壤全氮、有机质、Cl-含量和多酚氧化酶活性较低。说明与施用化肥或不施肥处理相比,蔗地施用废液有提高土壤肥力和有机质、腐殖质含量的作用,但也使施用初期过氧化氢酶和多酚氧化酶活性异常升高,施废液的土壤种植甘蔗对废液养分吸收和环境净化有一定作用。

摘  要：
An experiment was conducted in sugarcane field to study the effect of six treatments [vinasse application (four application rates), CK1 (non-fertilizer) and CK2 (chemical fertilizer)] on soil physicochemical properties, catalase and polyphenol oxidase activity. The results show that total N, Cl-, organic matter (OM), humic acid (HA) content of soil improves under vinasse treatments. Catalase and polyphenol oxidase activity increase abnormally at sugarcane settling stage and then sharply decrease to CK2 level at sugarcane maturity stage. Catalase activity has extremly significant positive correlations with total N, OM, HA, and significant positive correlations with fulvic acid fraction(FAF), humic acid fraction (HAF) and Cl-(r0.05=0.811, r0.01=0.917, n=6). An obvious significant correlation also exists between polyphenol oxidase activity and OM, HA and Cl-content. At the latter stage of sugarcane growth, total N, OM, Cl- and polyphenol oxidase activity in soils under 75 ton CK treatment in non-sugarcane fields are lower than in 75 ton treatment in sugarcane fields. Soil fertility, OM and HA content, and catalase and polyphenol oxidase activity are higher in the four vinasse treatments than in CK1 and CK2 treatments. Sugarcane plantation absorbs vinasse nutrient and purifies soil environment when treated with vinasse.
