摘要
[目的]对诸城市土壤中的pH、有机质、碱解氮、有效磷、速效钾含量进行研究,进而分析评价诸城市的土壤养分丰缺,以期为诸城市的土地利用规划、农作物产量和科学施肥等方面提供依据。[方法]利用ArcGIS软件研究诸城市的土壤养分空间分布。[结果]诸城市土壤pH均值为6.10,有机质、碱解氮、有效磷、速效钾含量均值分别为16.95g/kg、108.58mg/kg、60.36mg/kg、168.35mg/kg。[结论]总体来看,诸城市的土壤呈酸性,土壤有机质含量处于适量水平,碱解氮和速效钾含量处于丰富水平,有效磷含量处于极丰富水平。
[Objective]The pH value, organic matter, effective nitrogen, available phosphorus and rapidly available potassium in the soils of Zhucheng were studied, and the soil nutrient shortages in the cities were analyzed and evaluated,so as to provide a basis for land use planning, crop yield and scientific fertilization in Zhucheng.[Method]This study used ArcGIS software to study the spatial distribution of soil nutrients in cities.[Result]The average soil pH value of Zhucheng City was 6.10, and the average values of organic matter, effective nitrogen, available phosphorus and rapidly available potassium were 16.95 g/kg, 108.58 mg/kg, 60.36 mg/kg and 168.35 mg/kg, respectively.[Conclusion]In general, the soils in Zhucheng are acidic, the soil organic matter content is at an appropriate level, the effective nitrogen and rapidly available potassium content are at a rich level, and the available phosphorus content is extremely rich.
