Abstract:

This paper researched the characteristic of trace element content in tea plantation soil, and discussed the influence rule of soil features to the trace element. Took the soil in ‘Niaowang tea’ plantation as the object, through the contrast research and the correlation analysis method, we concluded the results as follow: as a whole, the soil trace element content in ‘Niaowang tea’ plantation was lower than the mean value of China, but the available condition content was not still deficient, the trace element had not the obvious difference between the tea tree different planter pattern soil and the different level soil. In the soil pH value and the soil the manganese, the zinc content had the remarkable relevance, the organic matter and the effective zinc assume were remarkable being related, the clay mainly through the adsorption influence soil trace element, the soil major elements mainly had the influence through the influence crops to trace element’s absorption strength.
