摘　　要：本试验通过统计分析棉花不同种植密度下各生育期的果枝数、果节数、蕾铃数、脱落率和烂铃率,并对不同种植密度下不同采收时期的铃重、衣分以及皮棉产量进行了对比,综合判定适合鲁西北地区的棉花适宜种植密度为(6.0~7.5)万株/hm^2。The number of fruit branches,fruit nodes,cotton bolls,abscission rate and rotten boll rate of cotton at each growth period under different planting densities were analyzed,and the boll weight,lint and lint yield of different harvest times were compared. Finally,the suitable planting density for cotton production in the northwest of Shandong Province was determined as 60 000 ~ 75 000 plants per hectare.
