Targeted measures should be taken for cotton management in the middle and late stages
This year, cotton was affected by unfavorable weather such as low temperatures, cloudy and rainy days, and insufficient sunlight in the early stage, resulting in weak growth and delayed development of plants over large areas. In addition, severe natural disaster weather such as heavy rain and typhoons has occurred frequently recently, making the cotton production situation very serious.

Fertilizer management. Focus on the application of topdressing fertilizer and the mixed spraying of pesticides and fertilizers in the later stage. Generally, apply 5-7.5 kg of urea per mu to increase bolls and boll weight and prevent premature senescence. For cotton fields with late boll setting, few bolls in the middle and lower parts, or sufficient flower and boll fertilizer with late application timing, where cotton plants are still growing vigorously at the Beginning of Autumn, fertilizer should mainly be applied by spraying, with supplementary application in fertilizer-deficient areas. For cotton fields deficient in potassium and boron, promptly spray potassium fertilizer and boron fertilizer in combination with pest and disease control.
