Fertilization timing plays a critical role in regulating nutrient availability, vegetative growth, and reproductive development in bayberry (Myrica rubra), ultimately influencing yield formation and fruit quality. This study systematically examines the effects of different fertilization periods on bayberry growth stages, nutrient uptake efficiency, and yield components. By integrating theoretical analysis with empirical case studies, the research evaluates how basal fertilization, topdressing, and flowering-stage fertilization impact flower bud differentiation, fruit set, and fruit enlargement. Results indicate that appropriately timed fertilization significantly enhances nutrient utilization efficiency, improves yield components such as single fruit weight and fruit set rate, and contributes to better fruit quality. However, improper timing may lead to nutrient loss, imbalanced growth, and reduced productivity. Based on these findings, optimized fertilization strategies are proposed to improve yield stability and resource use efficiency. This study provides both theoretical insights and practical guidance for sustainable bayberry cultivation.
