To clarify the effects of high- and low-ridge planting patterns on wheat in the Yellow River Delta Region, the effects of high- and low-ridge planting mode on wheat plant height component index, leaf area index, yield and yield component factors, grain quality and other indicators were studied from 2021 to 2023, using wheat varieties Jimai 22 and Hengguan 35 as materials. The small ridge planting mode was used as control. The results showed that compared with the control, the plant height of wheat planted in high-ridge significantly decreased, while the peduncle and plant height index significantly increased. The plant height of wheat planted in low-ridge significantly increased, while the peduncle and plant height index significantly decreased. The leaf area and leaf area index of wheat in high- and low-ridge increased, while the functional leaf area index decreased. The number of spikes was increased by 11.15% to 20.26%, and the yield was increased by 9.73% to 14.15%. Wheat in high-ridge had more effective spikes than that in low-ridge did, contributing 41.18% of the yield with one-third of the planting area. In terms of wheat grain quality, there were no significant differences in protein content, wet gluten content, stability time, extensibility, and stretching area between high- and low-ridge wheat and the control. In summary, high- and low-ridge planting can significantly increase wheat yield, but has no significant impact on grain quality traits. High-ridge wheat has a higher population size and a greater contribution to yield compared to low-ridge wheat. High- and low-ridge planting can be used as a high-yield wheat planting mode in the Yellow River Delta Region.
