Comparative studies on the seasonal dynamics of the soil enzymic activities of Leymus chinensis and Puccinellia tenuiflora communities in Songnen Leymus chinensis meadow



Comparative studies on the seasonal dynamics of the soil enzymic activities of Leymus chinensis and Puccinellia tenuiflora communities in Songnen Leymus chinensis meadow



Acta Prataculturae Sinica 11(4): 28-34



Seasonal and vertical (soil depth) variations in catalase, urease, invertase ( beta -fructofuranosidase) and polyphenol oxidase activities of Leymus chinensis and Puccinellia tenuiflora communities in Songnen Leymus chinensis meadow were investigated. Relationships between the four kinds of soil enzymatic activities and physico-chemical factors were determined by correlation analysis.
