Effect of Fertilizer on Soil Enzymes Activity in Rhizosphere and Non-rhizosphere of Wine-making Sorghum

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.
