【Objective】Sophora alopecuroides is a kind of leguminous plant with characteristics of drought toler- ance,saline-alkali tolerance and resistance against the erosion by wind and sand. It is a kind of quality plant resource for conservation of water and soil. In this paper,the effects of two kinds of interactive treatment methods on seed ger- mination and seedling growth of S. alopecuroides were studied,which provided scientific basis for the utilization of this plant resources.【Method】 Using two common methods of breaking the dormancy of S. alopecuroides seeds by soaking in sulfuric acid and soaking in hot water,an interactive experiment was designed to calculate the germination rate,germination potential,germination index,vitality index,fresh weight,dry weight,water content and related in- dexes of seedling growth.【Result】 In the 20 treatment combinations,the pretreatment methods of 65%×80 ℃ and 85%×20 ℃ showed good performance in all indicators. Among the 20 treatments,65%×80 ℃ combined treatment group had the highest germination percentage,germination energy,germination index and vigor index. The 85%× 20 ℃ combined treatment group had the second highest effect. In terms of seed germination rate and seedling growth, compared with other treatments,the above two treatment groups had a shorter time delay and faster germination speed,and the seedling growth was better than other groups,and the difference was significant with the 0×20 ℃ group. At the same time,this study also found that,grouped by sulfuric acid concentration,the overall trend was 85% >75%>65%>95%>0,and the treatment effect of 80 ℃ warm water soaking for 20 min was better than that of other three warm water soaking temperatures.【Conclusion】65%×80 ℃ and 85%×20 ℃ pretreatments had better effects on seed germination and seedling growth of S. alopecuroides. This study can provide scientific basis for seed germination,seedling establishment and production practice of S. alopecuroides.
