摘　　要：本研究以生产上常规的等行距(8 000株/667 m^(2)、60 cm)为对照,设置2行宽窄行(60 cm、40 cm, 9 000株/667 m^(2)),2行宽窄行(60 cm、30 cm, 10 000株/667 m^(2))和3行宽窄行(70 cm、40 cm, 9 000株/667 m^(2))3个处理,探究不同密度及行距配置对高粱产量及抗性的影响。结果表明,最佳的栽培密度和行距配置是密度9 000株/667 m^(2)、2行窄行(60 cm、40 cm),试验结果可为高粱产业发展提供一定依据。In this study,the conventional equal row spacing(8000 plants/667 m^(2),60 cm)in production was used as the control,and two narrow rows(60 cm,40 cm,9000 plants/667 m^(2)),two narrow rows(60 cm,30 cm,10000 plants/667 m^(2))and three narrow rows(70 cm,40 cm,9000 plants/667 m^(2))were set up to explore the effects of different density and row spacing configuration on sorghum yield and resistance.The results showed that the best planting density and row spacing were 9000 plants/667 m^(2) and two rows of narrow rows(60 cm,40 cm).The results could provide a basis for the development of sorghum industry.
