This study summarized the effects of autumn pruning and the regulation of the nitrogen-potassium (N-K) ratio on the yield and fruit quality of loquats. Pruning in autumn can promote the growth of new shoots, make the tree crown more reasonable, and also accumulate more nutrients for photosynthesis. All these lay a foundation for flower bud differentiation and fruit growth. The regulation of the ratio of nitrogen to potassium can help make nutrient distribution more reasonable, make trees more resilient, and also promote sugar transportation, thereby increasing yield and quality. The combined use of these two management methods can make the vegetative growth and fruiting growth of loquats more balanced, the size of the fruits more uniform, and also extend the high-yield period of the orchard. Based on some field cases, this study also proposed more appropriate pruning methods and more precise nitrogen and potassium management plans. This study aims to provide a reference for high-yield and high-quality production of loquat, making the planting management more scientific and effective.
