棉花整枝可以控制棉株生长,调节株体内部养分的运送和利用,减少营养物质的消耗,使集中供给蕾铃的需要,并能改善棉田通风透光条件,增强制造有机养料的能力,从而降低蕾铃脱落和殭烂,增加结铃率,促进早熟,提高产量和品质。但是,整枝增产效果的高低与棉田密度大小、水肥供应情况、治虫好坏等因素以及整枝工作做的及时彻底与 Cotton pruning can control cotton plant growth, regulate the transport of nutrients within the plant and use, reduce nutrient consumption, so as to concentrate on the supply of the needles, and to improve cotton ventilation and light conditions, enhance the ability to create organic nutrients, thereby reducing the Falling bell and stiffness, increase boll rate, promote precocity, increase yield and quality. However, the pruning effect of increasing the level of density and density of cotton fields, water and fertilizer supply, good and bad worm and other factors and timely and thorough work done by the pruning
