研究了安徽土壤肥料信息系统中配方施肥决策的算法和模型中的参数。采用土壤养分校正系数法,得出了安徽省各地区土壤养分校正系数值及其与土测值之间的关系,从而根据土壤养分含量、作物种类和目标产量确定某一区域的施肥量,为土壤肥料信息系统中的施肥决策提供方法依据。
The algorithm and model parameters in formula fertilization decision-making in soil and fertilizer information system of Anhui Province were studied. Using soil nutrient correction coefficient method, the relationship between soil nutrient correction coefficient and soil measurement value in different regions of Anhui Province was obtained. Based on soil nutrient content, crop species and target yield, the fertilization amount in a certain region was calculated as Soil fertility information system to provide fertilization decision - making basis.
