摘　　要：本文首次研究了六年生床土根际与主根上、下土壤营养状况和化学性质。结果表明，土壤有机质的分布趋势是根上＞根下＞根际；全量养分变化不大；根区有效氮磷钾根上层＞根下层；床上ｐＨ值有根际＞根上＞根下的变化规律；盐基离子组成与ＰＨ的变化规律相同。The state of soil nutrition and chemical character of bed soil root zone of 6 -year-old were carried out.results showed that soil organic matter were upper levels soil of root>root>root zone. N,P,K of root regio were upper levels soil of root>lower levels soil of root.Change law of bed soil pH and salt-group were root>upper levels soil of root>lower levels soil of root.
