不同桐药套种模式对土壤理化性质的影响
Effects of different interplanting patterns on soil physical and chemical characters of Vernicia fordii
摘要
Abstract
In order to screen reasonable interplanting patterns in the Vernicia fordii plantation from the five medicinal plants including Polygonatum odoratum (PO),Polygonatum sibiricum (PS),Platycodon grandiflorus (PG),Ophiopogon japonicas (OJ),Lycoris radiata (LR),soil physical and chemical properties were mensured at different periods in this paper.The results showed that the physical and chemical properties were significant difference among different interplanting patterns and different soil layers with the same interplanting pattern while the overall change trend was similar among these treaments.The interplanting patterns V.fordii+PG and V.fordii+LR could significantly impact on soil physical properties that soil bulk density increased mostly by 33.14％,soil specific weight reduced mostly by 14.18％ and total porosity by 33.58％.The interplanting pattern V.fordii+PS and V.fordii+PG could significantly impact on N and P content that N content increased mostly by 62.83％,P content by 111.80％.The interplanting patterns V.fordii+OJ and V.fordii+LR could significantly reduce N,P and K content.The pattern V.fordii+PG,V.fordii+PS and V.fordii+PO could significantly increase soil organic matter content,mostly by 148.37％.关键词
