It is expected that the suitable cotton topping period in 2022 will be slightly earlier than normal in all Xinjiang cotton areas. Most cotton areas in northern Xinjiang west of Shihezi are around July 4th, northern Bazhou cotton areas and Hami cotton areas are around July 13th, and Changjizhou cotton areas and most other cotton areas in southern Xinjiang are around July 8th. It is advisable to top.
The topping period of machine-picked cotton and prosperous, high-density cotton fields should be appropriately advanced, while the topping period of weak seedling fields and cotton fields that were severely affected in the early stage can be appropriately postponed; various regions should consider the local cotton seedling growth and climate. Characteristics and variety layout, and in accordance with the principle of “the branches arrive at different times and the branches arrive at different times”, the cotton topping period forecast is refined.
