Temporal and spatial characteristics of soil C∶N∶P ecological stoichiometry under Phoebe zhennan plantation of Huitong
In conjunction with Machilus plantation of Huitong as study object.Study on soil organic C,total N,total P content and its temporal and spatialdynamic stoichiometry.Theresults indicated that there were obvious differences in soil nutrient contents and their stoichiometry under different layer and slope position.Soil nutrientcontents of surface were higher than the sub-layer soil.The Chad larger variability than the P had smaller variability in same layer.The soil nutrient was different in different slope position present:lower-slope ＞ middle-slope ＞ upper-slope.The effects of soil nutrient content was affected by season,shows winter ＞ autumn ＞ spring ＞ summer.The C∶N,C∶P,N:P value in different seasons showed significant difference.The N and N:P into a very significant positive correlation.So N∶P is mainly controlled by the total N content.The average value of soil N∶P is 1.59,and lower than other studies show that N∶P.It shows Phoebe zhennan plantation soil is lack of N.
