摘要
为明确山西黄芩田杂草的种类组成及群落结构,采用倒置“W”9点取样法对山西黄芩主产地临汾地区的黄芩田杂草进行调查。结果表明,山西省临汾市黄芩田杂草有67种,隶属于25科55属,其中,优势杂草有茵陈蒿、播娘蒿、狗尾草、猪毛菜和鹅绒藤等5种,区域性优势杂草有9种,常见杂草有11种,一般杂草有41种。洪洞山地地区黄芩的优势杂草为:出苗前茵陈蒿、播娘蒿,出苗期麦家公、茵陈蒿、鹅绒藤、米口袋,生长期茵陈蒿,花蕾期狗尾草、猪毛菜,种子成熟期狗尾草;襄汾平原地区为:出苗前小花糖芥、荠菜、播娘蒿、夏至草,出苗期夏至草、田旋花、播娘蒿,生长期夏至草、鹅绒藤、小花糖芥、荠菜,花蕾期藜、狗尾草、马齿苋、猪毛菜,种子成熟期薄蒴草、鹅绒藤、茵陈蒿。洪洞县黄芩生长期田间杂草群落的物种丰富度、多样性及均匀度较襄汾县和其他生长时期高,而优势度较低。
To clarify the species composition and community structure of weeds in the field of Scutellaria baicalensis in Shanxi province,the inverted"W"9-point sampling method was used to investigate the weeds in the field of Scutellaria baicalensis in Linfen,the main producing area of Scutellaria baicalensis in Shanxi province.The results showed that 67 weed species belonging to 25 families and 55 genera were found.Among them,5 species were considered as dominant weeds,including Artemisia capillaries,Descurainia sophia(L.)Webb.ex Prantl,Setaria viridis(L.)Beauv.,Salsola collina Pall.and Cynanchum chinense R.Br..There were 9 regional dominant weeds,11 common weeds and 41 normal weeds.The dominant weeds of Scutellaria baicalensis from pre emergence to seed maturity in Hongdong mountainous area were Artemisia capillaris and Descurainia sophia(L.)Webb.ex Prantl at pre emergence,Lithospermum arvense L.,Artemisia capillaris,Cynanchum chinense R.Br.and Gueldenstaedtia multiflora Bunge at emergence stage,Artemisia capillaris at growth stage,Setaria viridis(L.)Beauv.and Salsola collina Pall.at flower bud stage and Setaria viridis(L.)Beauv.at seed maturity stage.The dominant weeds of Scutellaria baicalensis in Xiangfen plain area were Erysimum cheiranthoides L.,Capsella bursa-pastoris(L.)Medic.,Descurainia sophia(L.)Webb.ex Prantl and Lagopsis supina(Stephan ex Willd.)Ikonn.-Gal.ex Knorring at pre emergence,Lagopsis supina(Stephan ex Willd.)Ikonn.-Gal.ex Knorring,Convolvulus arvensis L.and Descurainia sophia(L.)Webb.ex Prantl at emergence stage,Lagopsis supina(Stephan ex Willd.)Ikonn.-Gal.ex Knorring,Cynanchum chinense R.Br.,Erysimum cheiranthoides L.and Capsella bursa-pastoris(L.)Medic.at growth stage,Chenopodium album L.,Setaria viridis(L.)Beauv.,Portulaca oleracea L.and Salsola collina Pall.at flower bud stage,Lepyrodiclis holosteoides(C.A.Mey.)Fisch.et Mey.,Cynanchum chinense R.Br.and Artemisia capillaries at seed maturity stage.The species richness,diversity and evenness of weed community in Hongdong were higher than those in Xiangfen,but the dominance was lower.
