摘　　要：为烤烟的科学合理施肥提供参考,对云南省丽江市华坪、永胜、宁蒗、玉龙和古城5个烟区土壤取样分析。结果表明,丽江市植烟土壤pH平均值为6.13,全市大部地区土壤酸碱度适宜烤烟生长;有机质含量较丰富,有56.4%的土壤有机质含量大于40g/kg;速效氮、速效磷、速效钾和水溶性氯的平均含量分别为136.30,31.24,222.22,38.37 mg/kg。针对丽江市土壤养分状况,认为全市大部分烟区应施行"控氮、降氯、稳磷"的施肥措施,同时应根据实际情况,改善土壤酸碱度状态。In order to guide Scientific and rational fertilization the five tobacco-planting areas such as Huaping, Yongshen, N in tobacco production, soil fertilities in inglang, Yulong and Gucheng of Lijiang in Yunnan province were analyzed. The results showed that： the average of soil pH value was 6. 13 in Lijiang, and big parts of soil in Lijiang were suitable to planting tobacco. The content of soil organic matter was abundant, and there were 56.4% tobacco-planting areas where soil organic matter was more than 40g/kg. Average contents of other soil fertilities were as follow： available N 136.30 mg/kg, available P 31.24 mg/kg, available K 222. 22 mg/kg, and Water Soluble Chlorine 38.37 mg/kg. The suggestion to decrease N and Cl, and control P in most part of Lijiang tobacco-planting area was effected, and soil pH value also should to be adjusted according to the actual situation.
