Abstract: At 15 typical sites in Casuarina plantations in southern China,49 soil samples were collected,and 26 mixed samples were analyzed for 12 indexes:pH,available P,N,K,Ca,Mg and B,total Cu,Zn,Mn,Co and Fe. Results showed that there were significant correlation(p =0.10~0.01)between soil Ca,Zn,Mn and annual average tree hight increment(m/year),between soil pH,Co,Mn and annual average tree diameter at 1.3 m high(cm/year),and between soil P,K,Mg,Fe,Mn and average seedling diameter at ground level,and between soil P,B,Cu,Fe and VAM infection.But there was no significant difference between N and the 5 indexes.Besides,the effect of soil types on VAM infection was discussed.
