摘　　要：为探明丽江金沙江流域玉龙烟区植烟土壤养分状况,采集112份土壤样品分析pH、有机质、碱解氮、有效磷、速效钾、水溶性氯含量等指标。结果表明,玉龙植烟土壤pH均值为6.77,有机质为32.96 g/kg,水解性氮为123.44 mg/kg,有效磷为127.26 mg/kg,速效钾为238.58 mg/kg,氯离子为18.44 mg/kg。养分变幅pH 4.49~8.69,有机质为5.00~99.70 g/kg,水解性氮为13.90~350.00 mg/kg,有效磷为4.10~383.40 mg/kg,速效钾为31.00~671.00 mg/kg,氯离子为0.78~96.88 mg/kg。各养分变异系数从大到小依次为氯离子>有效磷>水解性氮>有机质>速效钾>pH,各养分变异系数较强,表明玉龙植烟土壤环境复杂多样。玉龙植烟土壤养分含量丰富但分布不均,在生产措施上应以降低土壤磷素、调控钾肥为主,兼顾氮肥施用。In order to explore the nutrient status of tobacco-growing soil in Yulong tobacco-growing area of Jinsha River Basin,112 soil samples were collected to analyze pH,organic matter,alkali-hydrolyzable nitrogen,available phosphorus,available potassium,water-soluble chlorine content and other indicators.The results showed that the average pH of soil in Yulong tobacco area was 6.77,the content of organic matter was 32.96 g/kg,the content of hydrolytic nitrogen was 123.44 mg/kg,the content of available phosphorus was 127.26 mg/kg,the content of available potassium was 238.58 mg/kg,and the content of chloride ion was 18.44 mg/kg.Nutrient amplitude pH was 4.49-8.69,organic matter content was 5.00-99.70 g/kg,hydrolyzable nitrogen content was 13.90-350.00 mg/kg,available phosphorus content was 4.10-383.40 mg/kg,available potassium content was 31.00-671.00 mg/kg,and chloride ion content was 0.78-96.88 mg/kg.The variation coefficient of each nutrient from large to small is chloride ion>available phosphorus>hydrolytic nitrogen>organic matter>available potassium>pH value,and the variation of each nutrient is strong,indicating that the soil environment of Yulong tobacco planting is complex and diverse.The nutrient content of tobacco-growing soil in Yulong was rich and unevenly distributed.The production measures should be based on reducing soil phosphorus,regulating potassium fertilizer,and taking into account nitrogen fertilizer application.
