Some Biogeochemical Characteristics of Tea Soils
摘要
Characteristics of the element abundance,material cycling,element budment budgent in tea soils were disucssed base on investigations of six tea plantations and the adjacent wast lnads in the Three Gorges region .The plantations have different soil-forming Parent materials,but similar landfomrs,and the same tea variety and colse ages.The rsults showed that tea growing could incereased the contents of organic matter,total and available N,P,Al and Mn;the elements enriched by tea trees were in the follwoing descending sequence: P>Ca>K>Mn>Mg>Zn>Al>Fe;elements returned throuhg litter of tea were in the sequence of Ca>Mn>P>Zn>Mg>K>Al>Fe;in the nutrient budget of the soil-tea system ,P and K were in deficit, whereas Al,Fe and Mn in surplus.
