新泰市玉米品种适应性试验OA

To identify high-quality maize varieties suitable for the ecological conditions of Xintai City,this study introduced five new varieties for comparative trials with local dominant cultivars.The results demonstrated significant trait differentiation among the varieties:XT-4 exhibited the highest yield potential but required high water and fertilizer inputs;XT-2 showed strong lodging resistance and high yield with superior overall traits;XT-3 demonstrated drought resistance and stable yield;XT-1 exhibited tolerance to high planting density and was suitable for mechanical harvesting;XT-5 was characterized by superior quality and specific use.It is recommended to implement differentiated variety deployment based on distinct ecological zones such as plains,hills,and mountains,and establish a localized production system featuring"dominant varieties+supporting technologies"to achieve the dual objectives of stable and increased grain production alongside efficient resource utilization.
