摘　　要：研究结果表明,利用植物生长复合调节剂稳早丰,盛蕾期轻控、盛花期重控,可调控和优化棉花株型,增强根系活力和叶片光合速率,加快棉铃干物质积累、提高铃重,成铃时空分布合理、优质铃数增加,单产皮棉提高22.9%.The results showed that with small dose at square-bloom stage and big dose at peak flowering stage, the regulator 'Wenzaofeng' optimized plant-types of cotton, improved root vigor and leaf photosynthetic rate, enhanced accumulation of dry matter and weight of cotton bolls, yielded temporal and spatial boll distribution, and increased high-quality bolls. Compared with the control, cotton lint yield was increased by 22.9%.
