目前，长江流域麦后直播棉高产集中结铃的群体特征尚不清楚。在这项研究中，从2014年到2015年调查了3个品种的棉花植株结构，这些品种在大麦收获后直接播种，表现出高产和集中结铃。鉴定了促进集中结铃和高产的植株特性。结果表明，当纯氮量为150 kg hm-2时，国新12-1的籽棉产量最高。2015年，苗期施氮量100%、开花期施氮量为0的SRF（纯氮150 kg hm−2）处理的棉花籽棉产量最高。籽棉产量与8月15日~ 8月30日成铃率呈显著正相关（r2014= 0.948**，r2015= 0.976**）。分析了不同棉花群体的植株构型指标，并利用拟合系数大于0.85的不同方程拟合了这些指标与产量和RBT的关系。在生产上，这些研究结果可以为棉花生长管理提供指导，以实现更高的产量和集中结铃后直接种植大麦。
At present, the characteristics of plant population exhibiting both high yield and centralized boll-setting under the planting pattern of direct seeding of cotton after barley harvest in the Yangtze River basin are unclear. In this study, the cotton plant architecture was investigated from 2014 to 2015 with three varieties, which were directly sown after barley harvest and showed high yield and centralized boll-setting. The plant characteristics promoting both centralized boll-setting and high yield were identified. The results show that when the pure nitrogen amount was 150 kg hm−2, the seed cotton yield of Guoxin 12–1 was the highest. In 2015, the cotton plant with the SRF (pure nitrogen 150 kg hm−2) applied at a ratio of 100% at the seedling stage and 0 at the flowering stage showed the highest seed cotton yield. A significant positive correlation between the seed cotton yield and the ratios of boll setting from August 15 to August 30 to total bolls (RBT) was found (r2014= 0.948**, r2015= 0.976**). The plant architecture indexes of different cotton populations were analyzed and the relationships between those indexes and the yield and RBT were simulated using different equations with fitting coefficients above 0.85. In production, these findings can provide guidance for cotton growth management in order to achieve a higher yield and centralized boll-setting for directly sown cotton planted after harvesting barley.
