| 摘 要： | 为了直观清晰地表达田间信息的空间分布状况,为农田的定位施肥等农田精细管理提供依据,利用Surfer8.0软件中提供的克立格插值法处理农田信息数据,分别绘制在不同采样方案下土壤速效磷的等值线分布图,并对其进行了定性和定量分析,确定了合理的采样方案。又分别绘制了碱解氮、速效磷、速效钾与小麦产量的三维线框图,该图直观、清晰地反映了碱解氮、速效磷、速效钾与小麦产量的空间变异性分布情况以及它们之间存在的正相关关系。

| Abstract: | In order to reflect the spatial variability of farm information,This paper presented the data of the field information by using Kriging in Surfer 8.0.The spatial distribution map of available P in the different sampling schemes were separately laid out.The rational sampling schemes was decided qualitatively and quantitatively.Then the wireframe of available P、 available K、 available N and wheat yield were laid out in order to reflect the spatial variability of farm information.This results can serve as a basis for precision fertilization and precision management in farm. |
