- Abstract:
-
Soil coring is used to investigate the vertical distribution of three kinds of fine root parameters and the chemical characteristics of artificial Robinia pseudoacacia forests soil in the northern slope of Qinling Mountains.And the influence of soil nutrients on the vertical distribution of the fine root is analyzed on the basis of the research of the two aeras.It is revealed that the fine root parameters distribution in the soil decrease with the increase of soil depth.Many of the soil nutrient factors show different changes of their own.The vertical distribution of the fine root parameters in the soil is influenced by the soil nutrient factors.The influence of the soil organic matter and total nitrogen on the vertical distribution of the fine root parameters is the most positive.Among the three kinds of fine root parameters (fine root biomass,fine root surface area,fine root length density),fine root surface area has the most close relation with the nutrient acquisition.
