定量遥感参数与作物肥水模型链接初探

针对当前作物肥水模型和定量遥感参数在农业上应用的各自局限性 ,提出通过完善定量遥感的输出接口和作物模型的输入接口 ,将定量遥感参数与作物肥水模型进行链接 ,通过建立不同生育时段订正的绿度指数和叶片氮素分段函数以及订正的湿度指数与耕层土壤、植株水分及产量品质函数 ,使得生产上大范围、动态的肥水监测成为可能 ,最后对应用链接模型通过不同肥水管理措施对作物产量和品质进行调控的前景进行了展望

Preliminary Studies on the Interlinkage Between the Remote Sensing Parameters and the Crop Fertilizer and Moisture Models

To solve the limitations of crop models and quantificational remote sensing parameters in agricultural applications,this paper suggests improving the export interface of quantificational remote sensing and the import interface of crop models and constructing relative chlorophyll content and the leaf nitrogen content,humidity index and the plowing level soil moisture,plant water content and yield quality to make wide and dynamic inspection and diagnosis possible in agricultural production.It also studies the prospects on the control of the crop yield and quality by the application of fertilizer and water management measures under the guidance of interlinkage models.
