Abstract

In this paper, in order to make the WOFOST model better simulate the crop growth model, by using the Penman-Monteith formula to adjust the estimate of crop evapotranspiration so that it can better simulate the effects of water stress on crop growth; using the crop real-time observation data to calibrate and validate the crop growth simulation model, to improve the crop simulation model under the water stress production level, and some critical processes of the crop simulation model were calibrated by real-time monitoring information, the parametric crop simulation model was reinitialized to optimize the crop model, to achieve the optimal exploration of the crop model, the fully reasonable application of agricultural crops to monitor the regional crop growth information, simulation study on reasonable application method, so that the regional crop growth and reasonable monitoring of production and accurate forecast
基于农业监测数据的作物生长模型研究
本文为使WOFOST模型能更好地模拟作物生长模型,采用Penman-Monteith公式对作物蒸散估算值进行调整,使其能更好地模拟水分胁迫对作物生长的影响;利用作物实时观测数据对作物生长模拟模型进行校准和验证,以改进水分胁迫下的作物模拟模型的生产水平,并通过实时监测信息对作物模拟模型的一些关键过程进行校准,对参数化作物模拟模型进行重新初始化,对作物模型进行优化,实现对作物模型的优化探索。充分合理应用农业作物监测区域作物生长信息,模拟研究合理应用方法,从而对区域作物生长进行合理监测和产量准确预测
