- Abstract:
- The rhizosphere and non-rhizosphere soils were sampled by peeling the adhering soil of the tree roots in two types of herbages,planted in the triploid of Populus tomentosa woodland,which was converted from cropland to forest.The results showed that C:N ratio and pH in non-rhizosphere were bigger than those in rhizosphere in the corresponding patterns.The C:N ratio of rhizosphere and non-rhizosphere in natural herb pattern was bigger than that in ryegrass(Lolium multiflorum L.) pattern,while the pH was reverse.The N:P ratio(the ratio of available nitrogen to available phosphorus) of rhizosphere and non-rhizosphere soils in two types approached the Red field ratio(14:1).And the available potassium was the lowest from April to May,while maximal from October to November.The correlation between C:N ratio and available potassium in ryegrass type,C:N and N:P ratio in natural herb type of rhizosphere soils of Populus tomentosa was positive significant,with the correlation coefficients 0.639 7 and 0.712 5 respectively.
