鲁中(费县)烟区土壤养分特征及其调节措施

The characteristic s of soil nutrient in tobacco growing district in Feixian County and its regulation

山东费县适宜种植优质烟的土壤主要有3个亚类,分别属于普通棕壤、淋溶褐土和潮褐土。在费县不同类型的地块采集178个土壤样品进行分析化验,结果表明,费县主要植烟土壤的pH值介于微酸性至中性范围,有机质和有效磷含量中等偏低,大部分土壤有效氮、速效钾含量中等偏高。为此提出该区烟草施肥中应该掌握“控氮、增磷、稳钾”的施肥对策。

Three soil subgroups,belonging to brown soil,glyic soil,leaching drab soilare respetively,are suitable for the planting of flue-cured tobacco in Feixian,Shandong Province.From vast sampling and analy-sis of soils in different regions of Feixian,it can be seen that the pH of the soils ranges from acidity to neutral.The contents of organic matter and available phosphorus are medium to low,while the contents of available nitrogen,potassium are medium and high respectively in most soils.The fertilization method of reg-ulating nitrogen,increasing phosphorus,stabilizing potassium in tobacco production is put forward.
