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 explore the suitable method of soil fertility evaluation in Guizhou tea plantation, the fuzzy mathematics and the correlation analysis principle were used to evaluate the soil fertility of the bird king tea production area in the south of Guizhou Province by using the method of soil fertility quality index. The results showed that among the eight fertility indicators, the weight coefficient of available potassium was 0.157, the weight coefficient of soil organic matter was the lowest, only 0.096, the soil fertility quality reached 4% of grade Ⅱ soil and grade Ⅲ soil was 64 %, Ⅳ grade standard soil accounted for 32%, soil fertility quality is still suitable for the growth of tea trees.
