Effect of different planting patterns on agronomic traits of silage maize

To investigate the effects of different planting patterns on agronomic characters and yield formation of silage maize, Xinsiyu 19 silage maize was selected, and there were seven different row spacing planting patterns (30+60)、(10+66)、(17+50)、(60+60)、(76+76)、(40+60) and (30+90) cm. The results showed that the plant height, ear height, and other agronomic traits, leaf area per plant, SPAD value, and dry weight per plant of the (60+60) cm planting pattern were higher than those of the other cropping patterns. With the increase in planting spacing, the light transmittance in the lower canopy of silage maize was increased. The canopy structure of silage maize is reasonable when planted in (60+60) cm, the yield of silage maize under (60+60) cm cultivation was significantly higher than that of other planting models. In different planting patterns, the agronomic traits of maize were good with the increase in row spacing, and it is conducive to the formation of silage maize production when planted in the (60+60) cm planting model.
