The phenomenon of soil sickness in the continuous cropping of ginseng is a: serious problem for the cultivation practices and is an unelucidated subject scientifically.
Present study is concerned mainly with ecochemical search on the cause of soft sickness in the continuous cropping of ginseng and the obtained results are summarized as follows:
The humic substances isolated from both cultivated and uncultivated soils with ginseng were compared with respect to its IR spectra but any difference which may be causative of soil sickness between them was not detected.
In contrast, some saponin-like substances extracted from the ginseng cultivated soil in root zone were detected but not from the uncultivated soil. Presumably, the saponin-like substances in the soils are originated from the ginseng radices and are accumulaetd in root zone year by year, while the interrelation between the root exudate of ginseng and soil sickness is still obscure.
According to a survey on the distributive pattern of microflora in rhizosphere of ginseng radices the number of fungi is relatively diminished with the cultivation . years, while the number of actinomycetes is increassed.
It is supposed that the soil sickness in the continuous cropping of ginseng has any correlation between the activities of microflora in rhizosphere and the root exudates.
