The fertility of soil was diagnosed and integratively evaluated by modified Nemoro Index with eight indexes, i.e. pH, organic matter, total N, P, K and available N, P, K on three national Chinese medicinal materials GAP (Good Agricultural Practice) experimental plots of Pogostemon cablin, Citrus medica and Morinda officinalis in Guangdong. The results showed that the pH, organic matter and other major nutrient contents were low and imbalance. There are lots of nutritive disturbance factors. The level of soil integrative fertility in any of the plots was poor.
通过改良内梅罗指数，利用pH值、有机质、全氮、磷、钾以及有效氮、磷、钾这八项指标，对广东的广藿香、化橘红和巴戟天三个国家级中药材GAP（良好农业规范）试验地的土壤肥力进行了诊断和综合评价。结果表明，pH值、有机质和其他主要养分含量较低且不均衡。存在许多营养干扰因素。任何一个试验地的土壤综合肥力水平都较差。
