Abstract: Cultivation technology of water and fertilizor for maize under large ridge double row shallow burying drip irrigation was suitable for the high-yield and high-efficiency cultivation mode of maize in Qiqihar. Precise irrigation and fertilization according to demand can significantly improve water and fertilizer utilization, save time and effort, and increase production and efficiency. This paper introduced cultivation technology of water and fertilizer for maize under large ridge double row shallow burying drip irrigation from the drip irrigation system installation, fine land preparation, select varieties scientifically, sowing at an appropriate time, strengthen field management, green prevention and control of diseases and pests, harvest at an appropriate time.
