摘要
对曲靖烟区83个土壤样品养分现状的分析。结果表明,pH值平均值为6.24,有机质36.4g/kg、全氮0.9g/kg、全磷0.7g/kg、全钾4.6g/kg、碱解氮127.11mg/kg、速效磷28.80mg/kg、速效钾194.23mg/kg。曲靖烟区土壤养分含量丰富,部分植烟土壤为酸性和偏酸性。针对曲靖烟区植烟土壤养分状况,应当合理控制氮、磷、钾的施肥量,并应适当调节烟区土壤pH值。
83 soil samples from tobacco growing areas in Qujing were analyzed. The average contents were as follows: pH 6.24, organic matter 36.4 g/kg,total nitrogen 0.9 g/kg, total phosphorus 0.7 g/kg, total potassium 4.6 g/kg, available nitrogen 127.11 mg/kg, available phosphorus 28.80 mg/kg, available potassium 194.23 mg/kg. The soil nutrient content was rich and part of soils were acidity in Qujing. It was suggested that control N, P and K in Qujing tobacco growing areas were effective and also pH value should be adjusted.
