【Abstract】 The nutrients, microorganisms and enzyme activities were studied in the woodlands of different mixed broadleaved stands.The nutrients were generally poor in all woodlands especially P content. Microorganism studies shaved that bacteria were found in highest numbers.Microorganism number and enzyme activity varied with different woodlands.更多还原
