Abstract:

The complex structure community and environment of ancient tea plantation, what make the fertility of soil can be better self-sustained, but as the growing economic value, the ancient tea plantation was jammed more and more intensive, which has affected the nutrition environment of tea. By setting up four different comprehensive measures (A, B, C, D) of processing, studying the effect of different processes on the soil nutrient of 0 to 40 cm of soil layer of ancient tea plantation. The results showed that processing B, D increased the content of pH value, organic matter, effective C, effective M of soil. The processing B, D, C could increase the content of alkalytic N, rapidly-available P, available S, Fe, Zn and available Cu of soil. The processing B could maintain the content of available K of soil of ancient tea plantation. The correlation analysis of soil nutrient of ancient tea plantation: rapidly-available P had positive relationship with organic matter and alkalytic N. Available S had positive relationship with alkalytic N. Effective C had positive relationship with pH value. Effective M had positive relationship with pH value and effective C. Available Zn had positive relationship with alkalytic N. Rapid-available P and effective C. Available Mn had positive relationship with available K.
