In order to explore the high-yield and high-efficiency planting methods of spring millet,Gonggu 88 was used as material,and two factors split plot experiment design was adopted.The main planting methods were 45 cm narrow row spacing（A₁） and 65 cm wide row spacing（A₂）.The split plot was planting density of 300,000 plants/ha（B₁）,400,000 plants/ha（B₂）,500,000 plants/ha（B₃）,600,000 plants/ha（B₄） and 700,000 plants/ha（B₅）,respectively The effects of 10 treatments on agronomic characters and yield of millet were studied.The results showed that plant height increased with the increase of planting density.Stem diameter,ear length,ear diameter,stem node number single ear weight,grain weight per ear,1,000 grain weight and grain yield all showed a gradual downward trend There were significant differences in ear length,ear diameter,single ear weight,single ear grain weight and grain yield.The yield of millet increased first and then decreased with the increase of density.In this experiment,the maximum yield was 4,916.67 kg/ha and 5,278.85 kg/ha respectively when the row spacing was 45 cm and the density was 500,000 plants/ha.
