摘要： 通过对贵州省8个主植烟区的384个土壤样品进行分析，旨在了解各主植烟区的土壤肥力状况，为各烟区科学施肥提供合理的建议。分析结果认为，贵州省各主植烟区的氮含量丰富。其中，铜仁铵态氮含量最高，为21.41mg/kg；贵阳最低，仅为17.06mg/kg。贵阳硝态氮含量最高，为23.47mg/kg；铜仁最低，为17.99 mg/kg。黔南速效磷含量最高，达到18.07 mg/kg；黔西南最低，为8.29 mg/kg。遵义速效钾含量最高，为178.29mg/kg；黔东南最低，仅为137.36mg/kg。有机质含量以六盘水最多，为34.36g/kg；铜仁最低，为22.53g/kg。各烟区的土壤均表现偏酸性。综合比较，遵义、毕节、黔南三个地区土壤肥力的综合表现最佳，满足优质烟草的生长条件。

Abstract: In order to learn soil fertility of main district planting flue-cured tobacco and give some reasonable advice on scientific fertilization, 384 soil samples from 8 main districts planting flue-cured tobacco were analyzed. The results showed that nitrogen of every district planting flue-cured tobacco was rich. NH4+ nitrogen of Tongren was richest. It was 21.41mg/kg. One of Guiyang was lowest. It was 17.06 mg/kg. NO3- nitrogen of Guiyang was richest. It was 23.47 mg/kg. One of Tongren was lowest. It was 17.99 mg/kg. Available phosphor of Qiannan was richest. It was 18.07 mg/kg. One of Qianxinan was lowest. It was 8.29 mg/kg. Available potassium of Zunyi was richest. It was 178.29 mg/kg. One of Qiandongnan was lowest. It was 137.36 mg/kg. Organic matter of Liupanshui was richest. It was 34.64g/kg. One of Tongren was lowest. It was 22.53 g/kg. The value of pH of every district planting flue-cured tobacco was under of 7.Generally compared, soil fertility of Zunyi, Bijie and Qiannan was best and it was good condition could cultivate high quality flue-cured tobacco.
