    Current Status of Soil Nutrients and Suggestions for Fertilization in Jian'ou City

    • 摘要: 为掌握建瓯市耕地土壤养分状况,于2017年采集建瓯市耕地0~20 cm土壤样本294个,测定土壤pH值、有机质、碱解氮、速效钾、有效磷、交换性钙、交换性镁、有效硫、有效锌及有交硼含量。结果表明:建瓯市耕地土壤pH值整体呈酸性及以上水平,平均为4.85;有机质、碱解氮含量整体呈中等偏上水平,平均分别为26.78 g·kg-1、122.60 mg·kg-1;有效磷含量处于丰富水平,平均为51.62 mg·kg-1;速效钾含量处于中等水平,平均为101.45 mg·kg-1;交换性钙、有效锌、有效硫含量呈丰富水平,平均分别为637.74 mg·kg-1、3.78 mg·kg-1、40.08 mg·kg-1;交换性镁含量处于中等水平,平均为79.01 mg·kg-1;有效硼含量缺乏,平均含量为0.47 mg·kg-1

       

      Abstract: In order to understand the soil nutrient status of cultivated land in Jian'ou City, 294 soil samples from 0-20 cm soil layer of cultivated land in Jian'ou City were collected in 2017, and the soil pH and the contents of organic matter, alkali nitrogen, available potassium, available phosphorus and exchangeable calcium, exchangeable magnesium, available sulfur, available zinc and available boron were measured. The results showed that the soil pH value of cultivated land in Jian'ou City was acidic and above, with an average of 4.85. The contents of organic matter and alkali nitrogen were in the upper middle, with an average of 26.78 g·kg-1 and 122.60 mg·kg-1, respectively. The contents of effective phosphorus was abundant, with an average of 51.62 mg·kg-1; the contents of available potassium was moderate, with an average of 101.45 mg·kg-1; the contents of exchangeable calcium, available zinc and available sulfur are abundant, with an average of 637.74 mg·kg-1, 3.78 mg·kg-1, 40.08 mg·kg-1, respectively; the content of exchangeable magnesium was moderate, with an average of 79.01 mg·kg-1; the content of effective boron was deficient, with an average content of 0.47 mg·kg-1.
