Abstract: 【 Objective 】To clarify the impact of Sophora alopecuroides L. extracts on allelopathy of Hami melon seed germination by investigating the interactive effects of soil extracts (continuous cropping for 2 years and 7 years) and different concentrations of Sophora alopecuroides L. (5, 25 and 50 g/L) on the seed germination of Hami melon.【 Methods 】The germination potential, germination rate, germination index, and allelopathy response index of the Hami melon seeds were determined using the filter paper method in Petri dishes.【 Results 】The continuous cropping soil extracts significantly inhibited the seed germination rate, with a decrement in germination rate of 30.56% and 41.67% respectively. Similarly, Hami melon seed germination rate decreased by 19.44%-61.11% after treatment of Sophora alopecuroides L. water extracts. However, further findings from the interaction effects of continuous cropping soil extracts and Sophora alopecuroides L. extracts on seed germination indicated that low concentration of Sophora alopecuroides L. extracts (5g/L) could clearly reduce the long-term continuous cropping barrier effect of Hami melon (7 years) compared to 2 years. 【 Conclusion 】Low concentration of Sophora alopecuroides L. (5 g/L) might mitigate the seed germination allelopathy caused by long-term continuous cropping of Hami melon.
