How can management prevent and control late-stage premature senescence in cotton? Please provide methods. To prevent and control late-stage premature senescence in cotton, you can refer to the following methods: 1. Fertilizer and water management: According to the condition of the cotton plants, the climate and the soil conditions, apply the flowering and boll fertilizer heavily; if the flowering and boll fertilizer is insufficient, then apply a top-dressing fertilizer. After mid-August, if the maximum field water-holding capacity is below 60%, and in early September below 55%, water promptly to promote fertilizer with water and ensure the fertilizer effect is exerted in time. If cotton premature senescence is caused by soil potassium deficiency, while applying base fertilizer, increase the application of potassium sulfate or potassium chloride by 5-10 kg during the seedling and bud stages. When fertilizing, be sure to plow deeper than 20 cm, apply the fertilizer at the plow bottom, achieve deep fertilizer application, promote root penetration downward, reduce fertilizer loss, and improve fertilizer use efficiency. During the flowering and boll-setting stage, if drought occurs, water lightly, carefully clean the furrows and beds to prevent waterlogging again; if waterlogging occurs, drain promptly.
