摘要：

古茶园复杂的群落结构和生态环境，使土壤肥力能较好的自我维持，但因古树茶日益增长的经济价值，古茶园受到的人为干扰越来越大，影响到茶树的营养环境。通过设置4个不同综合措施的处理，研究不同处理对古茶园0~40 cm土层的土壤养分的影响。结果表明，处理B、D使土壤pH、有机质、有效钙、有效镁含量增高。处理B、D、C可提高古茶园土壤碱解氮、速效磷、有效硫、有效铁、有效锌、有效铜的含量。处理B可保持古茶园土壤速效钾的含量。古茶园土壤养分的相关分析表明，速效磷与有机质、碱解氮成正相关；有效硫与碱解氮成正相关；有效钙与pH成正相关；有效镁与pH、有效钙成正相关；有效锌与碱解氮、速效磷有效钙成正相关；有效锰与速效钾成正相关。

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.
