The dynamic change of soil urease, invertase, phosphatase and catalase activities in rhizosphere and non-rhizosphere of wine-making sorghum fertilized with organic fertilizer or inorganic fertilizer in different growth period were studied by field experiment to know the effects of organic fertilizer and inorganic fertilizer on soil enzyme activities of wine-making sorghum and provide scientific basis for high quality and high yield cultivation of wine-making sorghum. The results showed that organic fertilizer was better than inorganic fertilizer on keeping soil enzyme activities, which went up in filling period. The soil enzyme activities were higher in rhizosphere than in non-rhizosphere during the whole growth period.%为了解不同肥料种类对酒用高粱根际土壤酶活性的影响,为贵州酒用高粱的优质高产种植提供科学依据,通过田间试验,对酒用高粱分别施用有机肥和无机肥,研究高粱根际与非根际土壤脲酶、转化酶、磷酸酶和过氧化氢酶活性在高粱不同生育期的动态变化.结果表明,施用有机肥对维持土壤酶活性的效果优于无机肥,且土壤酶活性在高粱灌浆期普遍升高.在高粱整个生育期内,根际土壤酶的活性高于非根际.
