中文摘要：

为探讨蔬菜不同区域和种植模式对土壤质量的影响,对贵州省高、中、低不同海拔区域的蔬菜高效种植模式的土壤进行取样,分析测定了土壤微生物区系和酶活性的变化。结果表明,不同区域蔬菜高效种植模式下微生物总数和细菌总数均明显高于传统种植模式,微生物多样性指数也有一定程度提高;磷酸酶、过氧化氢酶和脲酶活性不同程度地高于传统模式,过氧化氢酶和脲酶活性比传统模式分别提高1.37~1.44和1.51~2.80倍。不同区域蔬菜高效种植模式的应用,一定时期内有利于改善土壤环境质量。

英文摘要：

To investigate the effects of different vegetable growing regions and planting modes on soil quality,soils in high,medium and low altitude areas of Guizhou were respectively sampled under different vegetable efficient planting modes,and the variations of soil microbial flora and enzyme activities were analyzed. The soil microbial count and total bacteria of the vegetable efficient cultivation mode were significantly higher than that of the control （traditional planting mode） in each planting area,and the microbial diversity index was also improved to varying de- grees.The soil phosphatase,catalase and urease activities of the vegetable efficient planting mode were higher than that of the control.The soil catalase and urease activities were higher than that of the control by 1.37-1.44 and 1.51-2.80 times. Application of vegetable efficient planting mode in different regions will help to im- prove the soil quality in a given period.
