摘要
Abstract
In order to explore optimum maize planting ways ,taking new maize line Qing 301 as test material , each density adopted 4 row planting pattern ,the effect of different planting densities on maize yield in planting 2 rows in 1 m wide ridge was studied .The results showed that in the same planting mode ,the maize yield first increased and then decreased with the increasing of planting density ,the highest yield in 75 thousand plant· hm‐2 ;in the same density on the ridge ,double rows row spacing 35 cm ridge spacing 65 cm planting way was the best ,the highest yield was 12 .2 thousand kg·hm‐2 .The optimum model was density 75 thousand plant· hm‐2 and double rows row spacing 35 cm ridge spacing 65 cm planting way .关键词
