This study mainly examined the effects of high-density planting and drip irrigation combined management on the morphology and yield of bitter gourd, and analyzed the relationships between indicators such as vine length, branch number, leaf characteristics, flowering status, and fruit traits and yield. It was found that high-yield groups have advantages in canopy structure, water and fertilizer utilization, and disease control. Studies show that combining drip irrigation with reasonable planting density can significantly improve the utilization rate of water and fertilizer as well as market output. Meanwhile, this method can improve the quality of the fruit by adjusting the distribution of light and nutrients. This study aims to provide theoretical basis and technical reference for the bitter gourd industry to achieve sustained high yields.
