High-Yield Cotton Cultivation Practices in Arid Regions

This study focused on cotton cultivation in arid regions and analyzed the key factors influencing high cotton yield and water use efficiency. Results showed significant differences in yield and drought resistance between irrigated and non-irrigated cotton varieties. Among them, ‘Tamcot CD3H’ and ‘TX-CABUCS-2-1-83’ maintained high yields even without irrigation, demonstrating good drought tolerance. Moderately reducing irrigation (controlling to 80% of field capacity) can conserve water and improve water use efficiency while maintaining yield. Controlling irrigation timing and water temperature is also crucial, with irrigation at night and water temperatures maintained between 25 ℃ and 28 ℃. Using treated wastewater for irrigation in arid regions has not only increased cotton yields but also reduced reliance on chemical fertilizers and lowered costs. Adopting partial root zone dry irrigation and mulching has reduced water use while also improving yield and quality. This study proposes a series of effective practices for cotton cultivation in arid regions and introduces several promising technologies and regulatory measures.
