摘 要:针对农业部及陕西省农业农村厅提出的玉米增密度提单产行动,我们从2019年开始,在西安夏玉米生产区开展了夏玉米耐密宜机收生产技术试验研究及示范推广工作,总结并提出了以“优选品种、适墒早播、规范播种、适度增密、科学水肥管理、病虫害绿色防控、化控、一喷多促”等关键技术集成的一项技术体系。此项技术体系是降低夏玉米种植成本、提高单产及种植效益的有效途径,对指导当前夏玉米生产增产增效及粮食安全具有积极意义。Aiming at the project of increasing the plant density and yield of maize proposed by the Ministry of Agriculture and the Department of Agricultural and Rural Affairs of Shaanxi Province, we have, since 2019, been performing experimental research, demonstration, and promotion regarding high-density planting and mechanical harvesting-production technologies of summer maize in Xi’an summer maize production area and have summarized and put forward a system that involves many important techniques, such as “selection of varieties, early planting according to soil moisture, standardized sowing, moderate density increase, scientific fertilization and water management, green disease and pest control, chemical control, and one spray and more promotion”. This technical system is an efficient way to the reduction of costs, and the increase of yield and efficiency of summer maize, and has a positive significance in guiding the improvement of yield and efficiency of current summer maize and food security.
