ABSTRACT
<p><b>OBJECTIVE</b>To determine 5 phenolic acids in the soils around rhizosphere of Rehmannia glutinosa in the field under normal rotation and successive cropping.</p><p><b>METHOD</b>Phenolic acids related to allelopathy effect in the soils around rhizosphere of R. glutinosa were determined by HPLC.</p><p><b>RESULT</b>The growth of R. glutinosa under normal rotation was strong. During harvest, the dry weight of the root tube and the volume of the R. glutinosa under normal rotation were 6.02 and 7.71 times of the ones under successive cropping.</p><p><b>CONCLUSION</b>The seeding stage and elongating stage are the crucial periods for the autotoxic effect of the R. glutinosa under continuous cropping. During these periods, the content of coumaric acid, 4-hydroxybenzoic acid, syringic acid, and ferulic acid of R. glutinosa under successive cropping are notably negative correlation with the growth of the leaf and root tuber of R. glutinosa under successive cropping. Among them, ferulic acid plays a major role in the restriction effect on R. glutinosa under successive cropping.</p>
