Abstract
Cotton yield can be stabilized by regulating the number and weight of bolls through the application of growth regulators. A field experiment was conducted in Xiaya, Xinjiang, from 2021 to 2023. The primary treatment involved a 40% pyraclostrobin suspension (300 mL/ha) combined with different growth regulators: 14-hydroxylated brassinosteroid (150 mL/ha, M1), 0.1% thidiazuron (150 mL/ha, M2), or 8% diethyl aminoethyl hexanoate (150 g/ha, M3). Clear water (M0) was used as the control treatment. This study examined the interaction between year and treatment and analyzed key factors affecting cotton yield. The results indicated a significant interaction effect between chemical treatments and yield across the years. All treatments led to an increase in yield compared with the control, with notable improvements in the number of bolls per unit area, boll weight, leaf area index, and net photosynthesis rate of cotton leaves. From a spatial perspective, the treatments effectively enhanced the number of bolls in the upper part of the plant. A positive correlation was observed between the number of new bolls and seed cotton yield. Among the treatments, the M2 treatment proved to be the most effective, which substantially increased the number of bolls in the upper part of the plant, as well as the total number of bolls per unit area and boll weight, resulting in a significant yield improvement. These findings can guide the development of chemical regulation strategies for cotton production in the Aksu region of Xinjiang, China, providing a valuable reference for enhancing local cotton yield.
