摘 要：
为明确白浆型土壤栽参后土壤酸化与铝形态分布变化的关系,调查了白浆土土壤剖面及栽参后的土壤理化性质,并采用连续提取法对土壤中不同形态铝进行浸提。结果表明:白浆土成土过程中能够向土体提供大量活性铝;白浆型土壤栽参后,随栽参年限的增加,土壤中交换态铝、单聚体羟基铝、酸溶无机铝以及腐殖酸铝均有不同程度的增加,而且表现出非活性铝形态向活性铝形态转化的趋势,造成土壤交换态铝、单聚体羟基铝等活性铝增加明显。

摘 要：
The ginsengs are mainly cultivated in albic soil that distributes in Fusong and Jingyu countries in the Changbai Mountainous area,which is the main production area of ginsengs.In order to identify the effects of ginsengs growth on chemical and physical properties of soil,we have investigated some characters of albic soil profiles and ginseng soil,and extracted different species of aluminum with continuous-extraction in soil.The result showed that there are amounts of active aluminum in ginseng cultivated albic soil.With the elongation of ginseng cultivation period,the contents of exchangeble aluminum,monomeric hydroxy aluminum,acidolysis inorganic aluminum and organically complexed aluminum increased differently in albic ginseng soil.Moreover,inactive aluminum was gradually converted into active aluminum,which caused that the contents of active aluminum significantly to increase,such as exchangeble aluminum and monomeric hydroxy aluminum.
