Effect of Different Planting Patterns on Maize Agronomic Traits and Yield

In order to select effective plant pattern to guide maize production, Xianyu 335 was taken as experimental material to study the effects of different plant patterns on maize agronomic traits and the yield.The results showed that the flat planting could improve the yield,which higher than that of flat planting with ridge management and ridge tillage,there was significant difference between the former and the latter.Flat planting could increase the yield by 7.2% compared with ridge tillage.There were significant advantages in the leaf area of three ear-leaves,plant height,ear diameter and row number under the flat planting pattern.
