Abstract:
Objective To investigate the cause of continuous cropping obstacle of Rehmannia glutinosa and screen beneficial bacteria.Methods In vitro cultured plantlets and potted plants were inoculated with different isolated soil bacteria. The plants were harvested and weighted in 30 and 60 d,respectively.Results In the in vitro culture experiment,11 out of 48 strains displayed promoting action on the growth of plantlets,and 11 other strains showed inhibitory or lethal action.In the potted test,16 strains showed promoting action and 13 strains showed suppressing or lethal action.Conclusion Soil bacteria influence the growth of R.glutinosa significantly.The flora of rhizosphere bacteria may be disturbed by the cultivation of R.glutinosa and inoculation of beneficial bacteria might be effective on the resolution of continuous cropping obstacle of R.glutinosa.
