| 摘 要： | 为明确冀中地区适宜的棉花群体结构,在密度1.5万~10.5万株/hm2范围内设置6个水平,调查了不同种植密度处理的株高、果枝数、单株铃数、铃重、衣分和产量指标。结果表明:在冀中棉区多雨年份和精细整枝条件下,棉花高产优质的适宜种植密度为6.9万~8.7万株/hm2。

| Abstract: | In order to clear the suitable planting density of cotton in central Hebei,six densities from 15 000 to 105 000 thousand plants per hectare were designed in the experiment,and the plant height,number of fruit branch,boll number per plant,boll weight,lint percentage and yield were investigated.The results showed that the suitable planting density was from 69 000 to 87 000 thousand plants per hectare with fine plant pruning in rainy year in central Hebei. |
