摘　　要：为了解潍坊烟区土壤养分含量状况,2014年在全市各植烟县共采集烟田土壤样品592份,分析土壤p H值、有机质、碱解氮、有效磷、速效钾,同时挑选86个代表性样品测定交换性钙、交换性镁和有效硼。结果表明,全市烟田适宜p H值的土壤占95.44%,30.24%的土壤有机质含量偏低,土壤碱解氮、交换性钙、交换性镁含量偏高,有效磷、速效钾和有效硼含量较低。因此,建议在生产上采取"控氮,增磷、钾、硼,提高有机质"的施肥策略,同时合理地采取烟田轮作。In order to evaluate the soil fertility of Weifang tobacco planting area, total 592 soil samples from main tobacco growing areas of Weifang were collected, and the pH value, organic matter, hydrolytic N, available P and K contents were measured. Moreover, eighty -six typical soil samples were selected, and the exchangeable Ca, Mg and effective B contents were measured. The results showed that 95.44% soil samples had appropriate pH value, 30.24% soil samples were low in organic matter content. All of the soil samples were rich in hydrolytic N, exchangeable Ca and Mg, but low in available P, K and B. Therefore, controlling N fertilizer and increasing the application amounts of P, K, B fertilizer and organic matter was the suggested fertilization strategy, and taking reasonable rotation mode at the same time.
