本文结合安徽省萧县玉米种植情况,总结分析了玉米密植滴灌水肥一体化技术措施要点。品种方面,选用适宜密植、抗倒伏且适宜机械化作业的优良品种,并做好种子包衣或药剂处理;整地方面,通过秸秆精细处理和深翻松土等措施提高整地质量,结合精量播种技术,为密植栽培奠定基础;播种环节采用宽窄行配置与浅埋滴灌模式,确保水肥精准供应,保证苗全苗壮;施肥管理上,实行氮、磷、钾、锌平衡施肥与分次追肥,满足关键生育期需求;病虫害防控方面,推行“一喷多促”综合防治策略,结合土壤封闭与茎叶除草;收获环节,适当晚收增加千粒重,推广籽粒直收与配套烘干技术,实现全程机械化。2024年进行示范种植,实现了大面积均衡增产,提高了资源利用效率,促进了粮食生产与生态保护的协同发展。本文为玉米密植滴灌水肥一体化技术的推广应用提供参考。

The key measures of integrated drip irrigation and water fertilizer technology for maize planting were summarized and analyzed in Xiaoxian, Anhui Province. In terms of variety selection, certified high quality varieties suitable for dense planting, lodging resistance, and mechanized operations are chosen, with seed coating or chemical treatment applied. In terms of land preparation, land preparation quality was improved through precise straw management and deep tillage and loosening, combined with precision seeding technology, laying the foundation for dense planting. During sowing, wide-narrow row configuration and shallow-buried drip irrigation were adopted to ensure precise water and fertilizer supply and promote uniform, robust seedling emergence. For fertilization management, balanced application of nitrogen, phosphorus, potassium, and zinc, along with staged topdressing, was implemented to meet the demands of key growth stages. For disease and pest control follows an integrated “one-spray, multiple-promotion” strategy, combined with soil sealing and stem-and-leaf weed control. During harvesting, appropriate delayed harvesting is practiced to increase 1 000-grain weight, and grain direct harvesting and supporting drying technologies are promoted to achieve full mechanization. Demonstration planting in 2024 resulted in large-scale balanced yield increase, improved resource use efficiency, and synergistic development of grain production and ecological protection. This article provides a reference for the large-scale promotion and application of integrated drip irrigation and water fertilizer technologies.
