| 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17.99mg/kg。黔南速效磷含量最高,达到18.07mg/kg;黔西南最低,为8.29mg/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. |
