鸟王茶产地土壤肥力数值化综合评价研究

Integrated Digitization Evaluation on Soil Fertility for Niaowang Tea Plantation

为探求适宜于贵州茶园土壤肥力质量评价的方法,运用模糊数学和相关分析的原理,结合土壤肥力质量指数法对贵州省南部鸟王茶产地土壤肥力进行数值化综合评价。研究结果表明,参评的8个肥力指标中,速效钾的权重系数最大为0.157,土壤有机质权重系数最小,仅为0.096,区域土壤肥力质量达Ⅱ级标准土壤占4%,Ⅲ级标准土壤占64%,Ⅳ级标准土壤占32%,土壤肥力质量尚适宜于茶树的生长。

In order to find a suitable evaluation method for soil fertility of tea plantation in Guizhou province. The fuzzy mathematics and the related analysis were used and combined with soil fertility index for digitization evaluation the soil fertility of Niaowang tea plantation in south of Guizhou province. Based on eight indexes,pH,organic matter,total N,available N,total P,available P,total K and available K. The results show that,the available K of maximums weight value is 0.157,the organic matter of minimums weight value is 0.096.There are 4% samples meet the soil fertility of research regionⅡstandard,there are 64 % account toⅢ standard and 32 % are in Ⅳ standard,the soil fertility was still suitable in tea growth.
