The latest points for attention in cotton planting

Growing cotton has its unique way of growing, because cotton is the main raw material for cloth production, and it is widely used in daily life.

Maintain the suitable water content needed in each period; spray pesticides as little as possible to avoid drug damage; foliar spraying trace element fertilizer to avoid cotton deficiency; in the later stage, the parietal leaf is enlarged and elongated, the space is closed, and some old leaves need to be removed to improve the environment, ventilation and light.

4. Weeding

Weeds are unearthed soon in spring, herbicides can be used for those with weak roots, and those with strong roots can be pulled out directly. Weeds flourish in summer. Pluck them manually in time. Don't leave them until autumn to prevent seeds from falling. Avoid competing for water and nutrients.
