In order to precisely formulate weed control strategies for soybean field under maize-soybean and wheat-soybean rotation modes, the species and quantities of weeds were investigated in these two rotation modes. The results showed that during the two-year experiment, the weed occurrence in the maize-soybean rotation mode was 1.89 and 1.49 times higher than that in the wheat-soybean rotation mode, respectively. In the maize-soybean rotation mode, a total of 11 weed species were consistently observed over the two years, including two gramineous weeds and nine broadleaf weeds. The dominant weed species were the gramineous Echinochloa crusgalli and the broadleaf Chenopodium album and Abutilon theophrasti. The subdominant species were the gramineous Eriochloa villosa and the broadleaf Amaranthus retroflexus and Solanum nigrum. For the wheat-soybean rotation mode, eight weed species were commonly observed over the two years, including two gramineous weeds and six broadleaf weeds. The dominant species included the gramineous E.crusgalli and the broadleaf C.album and A.theophrasti, while the subdominant species was the broadleaf Solanum nigrum. The maize-soybean rotation mode exhibited two weed occurrence peaks: one from late May to mid-June, and another from late June to early July, with the weed occurrence during the first peak period being greater than that during the second. Conversely, the wheat-soybean rotation mode showed only one weed occurrence peak, primarily concentrated in early to mid-June.
