| Abstract: | To provide a theoretical basis for research on meadow balance of carbon budget,the effects of 4 different mowing types on soil respiration and soil microorganism are studied by detecting Hulunbeier meadow characters of soil respiration and soil microorganism.Results indicate that mowing influenced the soil respiration,carbon and nitrogen content of microorganism.In the four different mowing years of natural meadows,the highest soil respiration rate appears from noon to 14 p.m.For control areas,the highest v... |
