摘要
以东当归为试验材料,研究不同玉米套种株距和行距对其产量和抽薹的影响。结果表明,东当归垄间套种玉米株行距为1 m×3 m时,产量相对最高,为12882.6 kg/hm^(2),较最低产量增产32.99%,且抽薹率较低,为0.87%;东当归抽薹率在套种玉米株行距为0.75 m×2.00 m时最高,达2.17%。东当归抽薹率随着玉米套种株行距的增大呈“低—高—低”趋势。合理控制垄间套种玉米株距和行距,能有效提高东当归产量,控制抽薹,达到绿色生产、增产增收的目的。
Angelica acutiloba(Sieb.et Zucc.)Kitagawa was used to study the effect of different planting spacing and row spacing when interplanting maize on its yield and bolting.The results showed that when the planting spacing and row spacing was 1 m×3 m,the yield was the highest(12882.6 kg/hm^(2)),which increased by 32.99%compared with the lowest yield,and the bolting rate was lower(0.87%).The bolting rate of A.acutiloba was the highest when the plant spacing and the row spacing of interplanted maize was 0.75 m×2.00 m,reaching 2.17%.The bolting rate of A.acutiloba presented a low-high-low trend with the increase of maize interplanting spacing.We found that the yield of A.acutiloba could be increased effectively and the bolting could be controlled by reasonably controlling the plant spacing and row spacing of interplanting maize between ridges,so as to achieve the goal of green production and increasing yield and income.
