摘 要:通过田间试验,研究了栽参对土壤化学性质的影响。结果表明,随栽参年限的增加,土壤有机质、全氮、有效硅、交换性盐基离子含量、pH值和C/N比下降;活性铁、铝、锰和酸性阳离子(H+、Al3+)含量增加。This paper deals with the effect of Ginseng cultivation on chemical properties of soils in the field experiment. The results showed that the contents of organic matter, total nitrogen, available silicon, base exchangeable ions and the values of pH and C/N of soil were decreased; whereas the contents of activative Fe, Al and Mn and exchange able H + and Al 3+ were increased with the time of Ginseng cultivation. The above changes were more obvious in root region (5~10 cm) than upper (0~5 cm) and underlying (10~15 cm) region soils.
