摘要：[Objectives]To screen out the selenium-enriched Pueraria lobata varieties suitable for cultivation in Guangxi according to the natural selenium-enriching ability of 7 main cultivars.[Methods]Taking 7 main cultivars of P.lobata in different places as experimental materials,field cultivation was carried out on the selenium-enriched yellow soil in Shanglin County,Nanning City of Guangxi,to study the difference in selenium-enriching ability of different main cultivars and the comparison of selenium content in different parts,as well as the transport mechanism.[Results]Under the condition of soil selenium content of 0.78 mg/kg,the selenium content of the root tubers of the 7 main cultivars all reached the selenium-enrichment standard.The selenium content of a single root tuber of Heping Variety in Teng County,Guangxi was the highest,at 0.061 mg/kg;Guifenge No.1 was the second at 0.055 mg/kg,and the total selenium accumulation per unit area was the largest.The ranking of selenium content in different parts of the same variety was:leaf>vine>head>root tuber.[Conclusions]Guifenge No.1 has the highest yield and the largest total selenium accumulation,so it is the most suitable natural selenium-enriched variety for cultivation.
