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
In view of the current limitations of crop water model and quantitative remote sensing parameters applied in agriculture, this paper proposes to link the quantitative remote sensing parameters with the crop fertilizer model by improving the output interface of quantitative remote sensing and the crop model input interface, The greenness index of leaves and the leaf nitrogen segment function as well as the revised humidity index and topsoil, plant water and yield quality function make it possible to monitor large-scale and dynamic fertilizer and water production in production. At last, Prospects for the regulation of crop yield and quality are also forecasted
