| 摘 要： | 为初步探明连作土壤中酚酸类物质与土壤主要因子的相互关系,以同一植烟区域不同种植年限土壤(1、6、8、14、16 a)为对象,分析不同连作年限植烟土壤酚酸类物质的种类、含量,以及土壤理化性状和酶活性的变化,在相关性分析的基础上,利用逐步回归模型,探讨酚酸类物质与土壤理化性状和酶活性的相互关系。结果表明,连作导致土壤中酚酸类物质积累、植烟土壤酸化和养分失衡。逐步回归分析表明:间苯三酚对pH存在抑制作用,肉桂酸对过氧化氢酶活性存在促进作用,阔马酸对脲酶活性存在抑制作用;间苯三酚、阔马酸和酚酸类物质总量均受到脲酶的抑制作用,对羟基苯甲酸和肉桂酸分别受过氧化氢酶的抑制和促进作用;阿魏酸受脲酶、过氧化氢酶的抑制作用和蔗糖酶的促进作用;间苯三酚、对羟基苯甲酸和酚酸类物质总含量均受土壤pH的抑制作用。 |

| Abstract: | In order to ascertain the interaction within soil phenolic acids and the main properties of soil, soils of different plantation years (1, 6, 8, 14, 16 a) in the same area were selected as study objects. The types and contents of phenolic acids, soil physicochemical properties and the characteristics of soil enzymes activities were analyzed. On the basis of correlation analysis, the gradual regression model was used to explore relationships within phenolic acids and soil properties in continuous cropping tobacco soil. It was shown that continuous cropping resulted in the accumulation of phenolic acids, decrease of soil pH and nutrient imbalance. Correlation and stepwise regression analysis showed that soil pH was inhibited by phloroglucinol. Catalase activity was increased by cinnamic acid. Urease activity was inhibited by carbamic acid. The contents of phloroglucinol, caramelic acid and total phenolic compounds were inhibited by urease activity. The contents of p-hydroxybenzoic acid and cinnamic acid were either inhibited or increased by catalase activity. Ferulic acid content was inhibited by catalase and urease, yet was increased by invertase. The contents of phloroglucinol, p-hydroxybenzoic acid and total phenolic acids were inhibited by soil pH. |
