Abstract: We used generic number, individual density, biodiversity, and functional group index to analyze the effect of mowing practice on soil nematode community in alkalinized grasslands of Leymus chinensis in Songnen Plain, Northeast China. A total of 8,335 soil nematode individuals were collected, belonging to two classes, seven orders, 23 families, and 40 genera. The results indicated that the generic number and individual density of soil nematodes were significantly lower in the land under mowing practice (MP) treatment than that under fencing enclosure (FE) treatment, whereas the diversity index showed no significant difference between the two treatments. The results also suggested that PPI/MI was sensitive to mowing practice, which changed the composition of functional groups of soil nematodes, especially that of free-living soil nematodes.
