摘要
[目的]探索陕西省彬县耕地土壤的养分和质量,为配方施肥、优化农业生产布局提供参考.[方法]通过走访调查,采集冬小麦和夏玉米耕地土样,测定碱解氮、速效钾、有效磷含量,建立冬小麦和夏玉米耕地土壤养分丰缺指标体系,分析土壤养分丰缺现状及各养分分布情况.[结果]对冬小麦、夏玉米地块而言,土壤碱解氮和有效磷含量水平分布均以低水平为主,速效钾含量水平分布则以高水平为主.[结论]彬县农田主要养分限制因子是氮和磷,因此今后应加强氮、磷肥的施用.
Abstract
[Objective] The aim was to explore soil nutrient and quality of cultivated land in Binxian County, Shaanxi Province, provide reference for formula fertilization and optimization of agricultural production layout.[Method] Through visiting and investigation, collecting soil samples from winter wheat and summer maize cultivated land, alkali solution nitrogen, available potassium, available phosphorus content was determined, the index system of soil nutrient abundance and deficiency was established, the soil nutrient status and distribution was analyzed.[Result] As for winter wheat and summer maize plots, the content of alkali solution nitrogen and soil available phosphorus were mainly low level, and the distribution of available potassium content was mainly on the high level.[Conclusion] The main nutrient limiting factors of farmland in Binxian County are nitrogen and phosphorus, so fertilization of nitrogen and phosphorus should be strengthened in the future.
