基于GIS的百合主产区土壤养分评价及施肥建议

GIS-based Soil Nutrient Evaluation in Lily-growing Areas and Its Fertilization Recommendations

基于ArcGIS 10.2平台,对七里河区百合主产区土壤pH及主要养分、中微量元素含量进行插值处理,并生成主要养分空间分布图。结果表明,研究区域土壤呈弱碱性,中等肥力水平,其中有机质大部分区域属于中等水平,碱解氮属于中等偏高肥力水平,全氮和有效磷属于中等肥力水平,速效钾属于中等水平,微量元素养分属中低肥力水平。

Based on ArcGIS 10.2 platform, this paper relies on the project of formula fertilization in main LilyJs producing areas of Qilihe district on soil testing, the pH value, main nutrient status and the content of soil elements using different preprocessing method, and we get the spatial distribution map of main nutrient. The result shows that the soil in the study area is weakly alkaline and medium fertility level, which most of the organic matter is of medium level, and the alkali solution nitrogen belongs to the medium level, and the total nitrogen and available phosphorus belong to the medium level, and the available potassium is of medium level, trace element nutrient is low fertility level.
