安徽土壤肥料信息系统中施肥决策的研究

Fertilizer Application Decision in a Soil and Fertilizer Information System in Anhui Province

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。

We studied arithmetic and parameter in a model of Soil and Fertilizer Information System (SFIS) for Anhui Province. In this system soil nutrient correlation coefficient method was adopted to determine the relationship between soil nutrient correction coefficient and soil nutrient content in each region and to obtain fertilizer application rate in given regions on the base of soil nutrient content,crop and target yield. The method provided a base for the decision - making of fertilization in SFIS.
