Germination rate of Chinese cabbage after 3d sowing. M, R, and W represent monocultural soils mixed with undecomposed maize, rice, and wheat straw, respectively. DM, DR, and DW represent monocultural soils mixed with decomposed maize, rice, and wheat straws, respectively. CK is monocultural soil with no straw applied. Different letters are significantly different; the results are for the statistical analysis (p < 0.05, Tukey’s HSD test).
