摘　　要：为了摸清蒜套棉轻简育苗移栽模式下棉花新品种济5104的最佳种植密度,充分发挥其高产潜力并达到优质高产高效的目的,特设置不同移栽密度试验,研究其对棉花生长发育及产量的影响。结果表明,济5104在27 000~45 000株·hm^(-2)移栽密度范围内,生育期127天左右,33 000株·hm^(-2)最为适宜,其烂铃率较27 000株·hm^(-2)处理增加不显著,其皮棉单产最高为1 978 kg·hm^(-2),较45 000株·hm^(-2)处理增产17.0%。The best planting density of new cotton variety Ji 5104 under the intercropping of garlic-cotton was tested with the simplified seedling raising and transplanting technology.It was expected to fully realize the high-yielding potential and achieve good quality,high yield and efficiency.The results showed that the growth period of Ji 5104 was about 127 days in the range of 27 000 - 45 000 plants per hectare.The density of33 000 plants per hectare was the best one with the boll rot rate lower than that of 27 000 plants per hectare and the highest lint cotton yield as 1 978 kg·hm（-2）,which increased by 17.0% compared to that of 45 000 plants per hectare.
