Abstracts:In this paper,in order to understand the effect of the five interplanting patterns (Vernicia fordii+Polygonatum odoratum,V.fordii+P.sibiricum,V.fordii+Lycoris radiata,V.fordii+Ophiopogon japonicas,V.fordii+Platycodon grandiflorus),the experiment is to measure soil chemical properties(total N,total P,total K,hydrolysable N,available P,available K).The results showed that the physical and chemical properties were significant difference among different interplanting patterns,it was different the physical and chemical properties among different soil layers of the same interplanting pattern,the overall change trend was alike,but the difference was existence in different growth period.The interplanting pattern“V.fordii+ P.sibiricum Red”and“V.fordii+Platycodon grandiflorus (Jacq.) A. DC.”could impact significantly on N and P content, that N content increased mostly by 62.83%,P content by 111.80%.The interplanting patterns “V.fordii+ Lycoris radiata (L’Her.)Herb”and“V.fordii+ Ophiopogon japonicas （Thunb.) Ker Gawl.”could reduce significantly N P and K content.The pattern “V.fordii+ Platycodon grandiflorus”,“V.fordii+P.sibiricum”and“V.fordii+P.odoratum”could increase significantly soil organic matter content, mostly by 148.37%.The soil pH value was increased by all interplanting patterns.
