摘　　要：以棉花赣棉杂109为材料,设置1穴1株、1穴2株、1穴3株3个栽培模式以及7个不同种植密度共9个处理试验,研究不同的栽培模式和栽培密度对棉花农艺性状及其产量的影响。结果表明,以1穴2株、0.4 m×1.4 m的株行距、密度为35 700株/hm^2的条件比较适合直播技术,产量也最高。Taking Ganmianza 109 as the material,3 cultivation modes of 1 plant,2 plants and 3 plants per hole and 7 different densities were set up to study the effects of different cultivation modes and planting densities on the agronomic characters and yield of cotton.The results showed that,the condition of the planting density of 35 700 plants/hm^2 with 2 plants in 1 hole,row spacing of 0.4 m and line of 1.4 m,was more suitable for plate ground broadcast technology,and on this condition,the yield was the highest.
