不同栽培模式下青贮玉米的农艺性状
Effect of different planting patterns on agronomic traits of silage maize
摘要
Abstract
To investigate the effects of different planting patterns on agronomic characters and yield formation of silage maize,Xinsiyu 1 9 silage maize was selected,and there were seven different row spacing planting pat-terns (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 in-crease in planting spacing,the light transmittance in the lower canopy of silage maize was increased.The cano-py 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.关键词
