Abstract

In order to investigate the soil organic carbon mineralization characteristics of different dominant herbaceous plant species in typical grasslands, Leymus chinensis(L) was selected as the experimental site, Stipa Krylovii Roshev(S), Artemisia frigida(A), and Agrophorn crispam Gaertn(C) communities were selected as dominant species in the soil, and organic carbon mineralization cultivation experiments were conducted using soil without aboveground plants as a control. The results showed that the larger the soil particle size, the more significant the promotion of soil organic carbon mineralization effect, The results indicate that (>2mm) (297.71mg·kg−1) > (1mm > soil particle size < 2mm) < (242.67mg · kg−1) > (0.25mm > soil particle size < 1mm) (208.36mg·kg−1) > (soil particle size < 0.25mm) (186.51mg·kg−1), Among all treatments, the excitation effect of S was 70.73%, L was 58.05%, A was 33.73%, and C was 7.68%. Among all the treatments, only the cD group had an excitation effect of -3.93%.
