摘要
对资溪县7个乡镇的96份植烟土壤样品进行养分含量分析,并分析其相互关系,为资溪县烟草科学施肥提供依据。结果表明:资溪县植烟土壤的有机质含量平均值为33.217 g/kg,处于中等偏高水平;pH值以酸性为主;水解氮含量在极高水平,平均值为202.189 mg/kg,有效磷和速效钾含量偏低;有效铜和有效铁均处于较高水平,而有效锌处于中等水平。简单相关分析结果表明有机质与有效铁呈负相关,与其他元素呈正相关,其中与水解氮呈极显著正相关,与有效磷呈显著正相关,有机质与其他元素指标相关程度由大到小的顺序为水解氮、有效磷、有效铜、速效钾、有效锌和有效铁。
To provide base for scientific fertilization to tobacco in Zixi, the nutrient content of 96 soil samples collected from seven tohat：co planting counties of Zixi was analyzed, and explore the relationship of the nutrient. The results indicated that the average organic matter content was 33.217 g/kg, it was little higher than medium. The pH-value was mainly deflected to acidic. The hydrolysable nitrogen content was 202.189 mg/kg, was extremely high levels. The rapidly available potassium and phosphorus content was low. The available copper and iron was at a high level, and the available zinc was little higher than medium. The simple correlation analysis results indicated that the organic matter content significantly negatively correlated with available iron, significantly positively correlated with availaHe phosphorus, extremely significantly positively correlated with hydrolysable nitrogen. The organic matter content correlation with other nutrients were hydrolysable nitrogen〉available phosphorus〉 available copper〉 rapidly available potassium〉 available zinc〉 available iron.
