为加快兰州新区粮改饲项目实施进度，推动寒旱区灌区农业“以养带种、种养结合、农牧互促”的循环发展，促进草食畜牧业发展和农民增产增收。经多年试验示范，从播前准备、播期管理、田间管理、病虫害防治、适期收获等方面总结了兰州新区灌区粮饲兼用玉米优质高产栽培新技术，以期为提升当地粮饲兼用玉米生产水平提供技术指导。

In order to speed up the implementation of grain-to-feed conversion project in Lanzhou New District, promote the circular development of irrigated agriculture in cold and arid regions through integrated planting and livestock farming, and enhance the growth of herbivorous animal husbandry while increasing farmers' yield and income. Based on years of experiments and demonstrations, this study summarized new high-yield and quality cultivation techniques for dual-purpose grain and forage maize in the irrigated areas of Lanzhou New District, covering aspects such as pre-sowing preparation, sowing period management, field management, pest and disease control, and timely harvesting. The study aimed to provide technical guidance for improving the production level of dual-purpose grain and forage maize in the region.
