摘  要:
对河南烟区435个土壤样品进行分析,结果表明:土壤阳离子交换量平均值为135.6 mmol/kg,pH值平均值为7.18,各养分含量分别为有机质13.03 g/kg、有效氮59.45 mg/kg、有效磷13.93 mg/kg、有效钾142.94 mg/kg、水溶性氯35.75 mg/kg。针对河南省烟区植烟土壤养分状况,提出了稳氮、增磷、补钾、降氯的施肥措施,并应适当调节烟区土壤pH值。

摘  要:
435 soil samples from tobacco-growing areas in Henan were analyzed.The results indicated that the content of nutrient in soil showed a big variation in location.The average content was as follows: CEC 135.6 mmol/kg,pH 7.18,organic matter 13.03 g/kg,available N 59.45 mg/kg,available P 13.93 mg/kg,available K 142.94 mg/kg and soluble Cl 35.75 mg/kg.It was suggested to control N,increase P and K,and decrease Cl for balanced fertilization in Henan tobacco-growing areas were effective and also pH value should be adjusted.
