兴文县植烟土壤养分状况分析

Analysis on Tobacco-planting Soil Nutrients in Xingwen County

为了解宜宾市兴文县植烟土壤肥力状况,实现烤烟科学种植、施肥,提高烟叶产量、品质,本研究在兴文县具有代表性的烟田中采集了土壤样品30份,对其pH值、有机质及其他营养元素含量进行了检测。结果表明:植烟土壤pH值平均值为6.23,整体偏酸性;有机质平均值为3.18%,含量较为丰富;全氮、碱解氮平均含量分别为1.84 g/kg、164.20 mg/kg,均处于丰富水平;全磷、有效磷平均含量分别为0.89 g/kg、17.71 mg/kg,均处于缺乏水平;全钾、速效钾平均含量分别为19.04 g/kg、200.33 mg/kg,速效钾较为缺乏。

In order to explore the soil fertility status of tobacco-planting area in Xingwen County,30 soil samples were collected from the most representative tobacco field in Xingwen County,the pH value,organic matter content and other nutrient contents were determined.The results showed that the average pH value of tobacco-planting soil was 6.23,and the soil was overall acidic;the soil organic matter content was relatively rich,and the average value was 3.18%;the contents of total nitrogen and available nitrogen were rich,the average contents were 1.84 g/kg and 164.20 mg/kg,respectively;the contents of total phosphorus and available phosphorus were poor,the average contents were 0.89 g/kg and 17.71 mg/kg,respectively;the contents of available potassium was poor,the average contents of total potassium and available potassium were 19.04 g/kg and 200.33 mg/kg,respectively.
