The Response of the Free-Living Nematodes Species and Quantity to Grazing Intensity of Meadow Grassland

Abstract. To study of meadow grassland soil free lifing nematodes types and quantities under the grazing intensity, the results show that we captured 13 species free lifing nematodes in different grazing area.With the increase of the grazing intensity the total number of Free life nematodes gradually reduce, among them Bacterial feeding nematode and Omnivorous predator nematode gradually reduced with the increase of nematode grazing intensity and the Fungal-feeding nematodes quantities gradually increased . the number of the Bacterial feeding nematode and Fungal-feeding nematodes gradually decrease with the deepening of the soil layer under the different grazing intensity and Omnivorous predator nematodegradually increased
