In order to explore the effects of rape straw on peanuts and provide reference for the demonstration and promotion of new rape lines PW-1B and the rotation of rape and peanuts, in this study, five peanut varieties such as Yuhua 22, Yuhua 37, Yuhua 65, Yuanza 9102, and Pukehua 9 were taken as the receptor materials, the effects of different mass concentrations of aqueous extract of rape straw on peanut seed germination, seedling growth, and physiological characteristics were studied. The results showed that the rape straw aqueous extract had an inhibitory effect on the germination potential of peanut seeds but had no significant impact on the germination rate. The low concentration of rape straw aqueous treatment increased the lateral branch length of Yuhua 22 and Pukehua 9 and the main stem height of Yuhua 65 and Pukehua 9, and the promoting effect was not significant with increasing concentration, and the 0.1 g/mL of rape straw aqueous treatment significantly inhibited the root length of Yuhua 37 and the fresh weight of Yuhua 65 seedling. The three treatments with rape straw aqueous extract significantly increased the root length of Yuanza 9102 seedlings. Within the concentration range, the synthesis effect of the aqueous extract was promoted on Yuanza 9102, in contrast, the aqueous extract showed the allelopathic effect of promotion by low concentration and inhibition by high concentration on the other four varieties. The soluble protein content of Yuhua 22, Yuhua 65, and Yuanza 9102 was significantly higher than that of the control at different concentration treatments. The soluble protein of Yuhua 37 and Pukehua 9 was significantly higher than that of the control at 0.03 g/mL. The antioxidant enzyme activities of Yuhua 22 and Yuhua 65 were reduced after aqueous treatment with rape straw, and the POD activities of Yuhua 37 were reduced. In conclusion, the allelopathic effects of rape straw aqueous extract on peanut varieties varied among the varieties tested. All the aqueous extract treatments showed promoting effects on Yuanza 9102, indicating that Yuanza 9102 was more suitable for crop rotation with the new rape lines PW-1B.
