摘　　要：以唐古特红景天为试材,采用田间试验法,对人工栽培样地不同除草措施下杂草群落的物种组成、数量、高度以及生物量进行调查,研究了人工及覆黑膜除草方式对唐古特红景天样地药材品质、生物量和产量的影响。结果表明:CK处理下杂草种类最多有19种;人工除草处理下杂草种类次之,有15种;覆黑膜处理杂草种类最少,有10种。从杂草的数量、高度以及地上生物量来看,杂草的总密度、平均高度以及地上总生物大小依次均为CK处理>人工除草处理>覆黑膜处理,处理间差异极显著(P<0.01);药材产量和品质均为覆黑膜处理>人工除草处理>CK处理。综上,覆黑膜处理除草效果最佳,人工除草次之。Taking Rhodiola tangutica as material,field test was conducted. The density, height and above-ground biomass of different weeding methods under artificial cultivation were measured. Meanwhile, the effect of manual weeding treatment and mulching black film treatment on yield and materials quality and biomass values were studied. The results showed that CK recorded the most number of species which was 19 and that of manual weeding was followed which was 15. And that of mulching black film treatment was the smallest which was 10. The magnitude of weed density, mean height and total above-ground biomass, in turn, were CK treatment〉manual weeding treatment〉mulching black film treatment,showed significant difference （P〈0.01）; yield and medicine quality in turn, were mulching black film treatment〉manual weeding treatment〉CK treatment. In conclusion, the best weed control effect was mulching black film treatment and the manual weeding treatment took second place.
