Abstract: Abstract: In order to discuss the technical route of super high-yield cultivation of summer maize in the Yudong Plain, four dominant varieties were selected, and the combination of theoretical measurement and actual production was used to analyze the yield and yield components of the experimental high-yield field of summer maize and farmers’ high-yield field of summer maize. The survey is divided into three production levels, and the correlation and path analysis of the three components of production and production are carried out. The results showed that the yield increased from 10500~12000 kg/hm2 to 12000~13500 kg/hm2, and the number of harvested spikes increased by 7736.25 spikes/hm2, with an increase of 10.69%; the yield increased by 1343.4 kg/hm2, with an increase of 11.97%. The yield level increased from 12000~13500 kg/hm2 to above 13500 kg/hm2, and the number of harvested spikes increased by 6333.75 spikes/hm2, with an increase of 7.91%; the yield increased by 1482.6 kg/hm2, an increase of 11.80%. The direct path coefficient, the number of panicles (X1) was 0.8146, the number of kernels per ear (X2) was 0.1233, and the weight per thousand (X3) was 0.1275, indicating that the contribution to yield was in the order of panicle number>1000 grain weight>panicle number. Therefore, in the high-yield cultivation of summer maize in the eastern Henan Plain, the yield should be further increased by increasing the planting density. ''Zhongdan 909'', ''Denghai 605'', ''Denghai 618'', ''Zhengdan 958'' and other varieties, summer maize in the Yudong Plain achieved a yield of 13500 kg / hm2 or more, planting density of 87,000 ~ 91,500 plants / hm2, The number of harvested ears was 84,000~88500 spikes/hm2, the number of spikes was 480-485 grains, and the 1000-grain weight was 330-340 g.
