棉花整枝是棉田中期管理的关键性技术措施，对棉花产量高低影响较大。在实际操作过程中，整枝技术要与外部条件结合起来，以当前生产上推广的抗虫棉新棉 33B品种为例，应注意好以下几个方面的问题。 一、整枝与密度的关系棉花田间密度的大小与单株留果枝数、结铃数关系成反比 Cotton pruning is the cotton field management of the key technical measures, a greater impact on the level of cotton production. In actual operation, the pruning technology should be combined with the external conditions. Take the new cotton insect-resistant cotton variety 33B as an example, attention should be paid to the following aspects. First, the relationship between the pruning and density Cotton field density and the number of fruit leaves per plant remain unchanged, inversely proportional to the number of bolls
