摘　　要：本试验以少花蒺藜草种子为研究材料,通过设定不同的温度、土壤湿度、土壤基质和光照等条件研究环境因子对少花蒺藜草种子萌发的影响。结果表明:少花蒺藜草种子萌发最适温度为25℃,萌发最低温度为20℃,萌发最高温度为30℃;光照对少花蒺藜草种子萌发有一定影响,光照促进种子萌发;土壤湿度对其萌发有影响,最适萌发湿度为20%,最低萌发湿度为6%;少花蒺藜草种子萌发对土壤基质要求不严格,于沙土及草炭土中均可萌发。With Cenchrus pauciflorus Benth.seed as material to study the effect of different emperature,soil moisture,soil substrate and illumination on seed germination.The result showed that temperature had great influence on seed germination of Cenchrus pauciflorus Benth,and the lowest germination at 20 ℃,and the highest germination rate at 30 ℃,and the best suitable germination temperature was 25 ℃.Light could improve seed germination.Soil moisture had great influence on seed germination,the best humidity was 20%,the minimum humidity was 6%.Soil substrate had little effect on seed germination,and seed could germination in sand and turfy soil.
