摘　　要：通过对聊棉六号在密度为22.4株/m2条件下不同的打顶时间处理,研究打顶时间对棉花产量及品质的影响,探讨棉花优质高效生产与打顶时间的最佳组合,为棉花管理和生产实践提供理论依据。结果表明:打顶时间对棉花产量和纤维长度影响显著,7月3日打顶的棉花产量高、纤维长。Through the treatment of the different topping time on Liaomian No. 6 under the 22. 4 plant / m2 density,we studied the influence of the topping time on cotton yield and fiber length,and explored the best combination of cotton high quality and efficient production and topping time to provide theoretical basis for cotton management and production practice. The results showed that the effect of topping time on cotton yield and fiber length was significant,the topping time on July 3rd had high yield and long fiber.
