顺昌县烟田土壤肥力状况分析

    Analysis of soil fertility in tobacco field of Shunchang County

    • 摘要: 通过对顺昌县烟田土壤pH值、有机质、碱解氮、有效磷、速效钾等属性指标的检测分析,结果表明:烟田土壤pH值偏低,有机质含量丰富,速效养分含量均在中等水平,土壤交换性钙、镁含量都较为丰富。生产上应重视施用适量石灰、白云石粉及碱性肥料,以调节土壤酸度;速效氮大于150 mg/kg的土壤应适当控制氮肥、重视钾肥的施用。

       

      Abstract: Some indexes related to soil fertility, such as soil pH, organic matter, available N, available P and available K in tobacco field of Shunchang County were analyzed. The results showed that the pH value of the tobacco field soil was slightly low, contents of organic matter were abundant, contents of available nutrients were mainly at moderate levels, and contents of exchangeable calcium and magnesium were rich. Based on these status, it needs to apply lime, dolomite powder and alkaline fertilizers in productive practice for adjusting active acidity in soil, and when content of available N is above 150 mg/kg soil, we should take attention in P application and control N level.
