结合多传感器监测的制种玉米花期调控技术数字化推广模式设计OA

To improve seed corn yield and benefit,a flowering stage regulation technology combined with multi-sensor monitoring and a corresponding digital promotion model were designed,taking Hongxiang Town,Liangzhou District,Wuwei City,Gansu Province,as research area.A satellite-ground collaborative monitoring system and a dynamic flowering stage prediction model have been construc-ted,supplemented by a precision water-fertilizer regulation system and a pest and disease control system,to create a government-in-dustry-academia-research-application promotion framework.Empirical results have shown that flowering stage synchronization rate in experimental treatment reached 92%,a 21 percentage points improvement over control treatment;yield increased by 21.5%,indicating remarkable effectiveness of technology's promotion.
