玉米“增密度”提单产集成技术项目在镇巴县的实践与创新探索

Practice and Exploration on Innovation of Corn "Increasing Density to Enhance Yield per Unit Area" Integrated Technology Project in Zhenba

摘要:

本研究聚焦镇巴县2024年玉米“增密度”提单产集成技术项目，通过创新“良种+良法+农机”融合模式，实现项目区玉米平均产量6 663 kg/hm²，较非项目区增产5.0%，核心攻关田最高产量达10 099.5 kg/hm²，同步推动化肥减量3.4%、化学农药用量减少1.5%。项目创新构建“五统一”标准化生产体系，研发适配山地地形的农机农艺融合技术，形成可复制的山区玉米高产栽培范式，为全国同类地区农业技术革新提供重要参考。

Abstract:

This study focuses on the 2024 corn "Increasing Density to Enhance Yield per Unit Area" integrated technology project in Zhenba County. Through the innovative integration of "improved varieties + advanced methods + agricultural machinery", the average yield per hectare in the project area reached 6 663 kg/ha, an increase of5.0% compared with non-project areas, and the highest yield per hectare in core demonstration fields reached 10099.5 kg/ha. Meanwhile, the project reduced chemical fertilizer use by 3.4% and chemical pesticide use by 1.5%.By establishing a standardized "Five Unifications" production system and developing agricultural machineryagronomy integration technologies suitable for mountainous terrains, the project has formed a transferable highyield cultivation paradigm for mountainous areas, providing significant reference for agricultural technological innovation in similar regions across China.
