为明确临朐县和蒙阴县植烟土壤养分状况及其与成土母质的关系，调查了两县植烟土壤的母质类型，采集并测定两县共79个土样的养分含量。结果表明，临朐县耕作层土壤全氮1.14 g/kg、全磷0.68 g/kg、全钾25 g/kg、碱解氮75.49 mg/kg、有效磷33.43 mg/kg、速效钾186.1 mg/kg，少数样点缺钾；蒙阴县耕作层土壤全氮0.73 g/kg、全磷0.54 g/kg、全钾19.6 g/kg、碱解氮61.54 mg/kg、有效磷33.36 mg/kg、速效钾123.2 mg/kg，少数样点缺氮，半数样点缺钾。两县植烟土壤全氮、全磷、碱解氮、有效磷和速效钾含量随土层的加深逐渐降低，全钾在各层次含量基本一致。页岩母质发育的土壤养分含量较丰富，石灰岩母质发育的土壤土层较厚且各层次养分含量丰富，花岗岩母质、砂岩母质和石灰性紫色砂页岩母质发育的土壤土层较浅且各层次养分含量较低。
為明確臨朐縣和矇陰縣植煙土壤養分狀況及其與成土母質的關繫，調查瞭兩縣植煙土壤的母質類型，採集併測定兩縣共79箇土樣的養分含量。結果錶明，臨朐縣耕作層土壤全氮1.14 g/kg、全燐0.68 g/kg、全鉀25 g/kg、堿解氮75.49 mg/kg、有效燐33.43 mg/kg、速效鉀186.1 mg/kg，少數樣點缺鉀；矇陰縣耕作層土壤全氮0.73 g/kg、全燐0.54 g/kg、全鉀19.6 g/kg、堿解氮61.54 mg/kg、有效燐33.36 mg/kg、速效鉀123.2 mg/kg，少數樣點缺氮，半數樣點缺鉀。兩縣植煙土壤全氮、全燐、堿解氮、有效燐和速效鉀含量隨土層的加深逐漸降低，全鉀在各層次含量基本一緻。頁巖母質髮育的土壤養分含量較豐富，石灰巖母質髮育的土壤土層較厚且各層次養分含量豐富，花崗巖母質、砂巖母質和石灰性紫色砂頁巖母質髮育的土壤土層較淺且各層次養分含量較低。

In order to explore the relationship between tobacco soil nutrients and soil parent materials,79 soil samples from tobacco growing areas in Linqu and Mengyin were analyzed. The results indicated that the average contents of nutrients in surface soil in Linqu were total N 1.14 g/kg, total P 0.68 g/kg, total K 25.0 g/kg, hydrolytic N 75.49 mg/kg, available P 33.43 mg/kg, available K 186.1 mg/kg. Few of the samples were K deficient. The average contents of nutrient in surface soil in Mengyin were total N 0.73 g/kg, total P 0.54 g/kg, total K 19.6 g/kg, hydrolytic N 61.54 mg/kg, available P 33.36 mg/kg, available K 123.2 mg/kg, few of the samples were N deficient, half of the samples were K deficient. The vertical distribution of soil nutrients in Linqu and Mengyin were essentially the same. Total N, total P, hydrolytic N, available P and available K contents decreased with soil depths. Total K content was essentially the same across soil layers. Soils developed from Shale parent material had high nutrient contents. Soils developed from Limestone parent material were thick and each layer had high nutrient contents. Soils developed from Granite parent material and Sandstone parent material were thin and each layer had lower nutrient contents.
