- Abstract
We studied the effects of RSD (Reductive Soil Disinfestation) on the soil sickness problem of ginseng (Panax ginseng C.A. Mey.). We also determined its effects on soil allelopathic substances, development of soil sickness, its ameliorating properties and effects on the growth of ginseng. We found that RSD treatment effectively reduced the contents of 7-phenolic acids (Gallic acid, dihydroxybenzoic acid, chlorogenic acid, syringic acid, p-Coumaric acid, ferulic acid, trans-Cinnamic acid) in ginseng soil, and ferulic acid was completely eliminated. The RSD treatment also promoted the growth of ginseng plants and reduced the incidence of ginseng soil sickness. There was a significant negative correlation between the growth and the contents of phenolic acids in soil. Thus, RSD treatment proved an effective method to reduce the allelopathy of ginseng and soil sickness.
