云南杜鹃群落不同海拔土壤养分状况分析
Soil nutrient characteristics of Rhododendron communities at different altitudes in Yunnan
摘要
Abstract
In order to study the content of Rhododendron soil nutrients among the altitude(2183~3310 m)in Yun-nan,we analyzed the characterization of the Rhododendron of soil and discussed the variation of soil nutrient with ris-ing of the altitude.In total,the soil of Rhododendron community in ten different altitudes were collected,and the Rhododendron soil characterization including pH,electrical conductivity,total dissolved solids,organic matter,total nitrogen,total phosphorus,total potassium and mineral elements were analyzed in our study.The results were as fol-lows:(1)The Rhododendron soil nutrients in different altitudes were significantly different with the character of ster-eoscopic change;(2)With the rising of the altitude,the pH,organic matter,total nitrogen,ammonium nitrogen,total manganese,and zinc in the soil of Rhododendron community soil was firstly increased,later decreased and finally in-creased.While,with the rising of the altitude,conductivity,total dissolved solids,total potassium,total phosphorus and total iron and copper in the soil of Rhododendron community showed firstly decreased,then increased and finally decreased;(3)The organic matter and total nitrogen of R.adenogynum community were higher than other species of Rhododendron at contigeous altitude.The soil nutrients in different altitudes were significant different,and soil nutri-ents correlated with each other.关键词
