| 摘 要： | The paper compared the effects of application of farm manure with chemical fertilizers on nitrification and denitrification in black soil, the result showed that the numbers of nitrobacterias and denitrobacterias in farm manure treatment were both higher than that of other treatments. The intensity of denitrification in chemical treatment was higher than that of manure treatment. The content of organic matter in soil was correlated with the intensity of nitrification and denitrification, and the coefficients were resnectively 0.9981 and 0.8693.
