通过对比国内外相关研究,研究了基于GIS平台建立大豆田间处方生成方法。选取采集于黑龙江红星农场120个采样点的土壤养分数据,利用Kriging插值法绘制土壤养分分布图。在此基础上,利用ArcGIS Desktop平台的内嵌空间分析模块进行插值分析获取处方图。通过实验证明,基于GIS平台建立的大豆处方图能够有效分析土壤养分与产量的相关性,并在短期决策上实现增产的目的。
By comparing the relevant research at home and abroad, the method of establishing soybean field prescription based on GIS platform was studied. Soil nutrient data collected from 120 sampling sites in Hongxing Farm of Heilongjiang Province were selected and Kriging interpolation method was used to draw the soil nutrient distribution map. Based on this, we use the interpolation analysis module of ArcGIS Desktop platform to obtain the prescription graph. The experiment proves that the prescription of soybean based on GIS platform can effectively analyze the correlation between soil nutrients and yield and achieve the goal of increasing production in short-term decision-making.
