Optimizing irrigation and fertilization system is a key measure to improve the yield and quality of kiwifruit (Actinidia spp.). This study takes the optimization of irrigation and fertilization system as the starting point, systematically explores the effects of different water-fertilizer combinations on the growth and development, physiological characteristics, yield formation and quality indicators of kiwifruit, and deeply analyzes the green planting cases of three typical kiwifruit producing areas, respectively showing the significant effects of low-frequency and high-efficiency drip irrigation combined with organic fertilizer to replace part of chemical fertilizers, micro-spraying technology combined with basal application + topdressing strategy, and dynamic regulation measures based on the water and fertilizer requirements of fruit trees on improving fruit quality and yield level. The study shows that moderate irrigation combined with the optimization of the ratio of organic and inorganic nutrients can significantly increase the single fruit weight, soluble solids content, vitamin C concentration and sugar-acid ratio, improve the appearance and internal quality of the fruit, while maintaining soil fertility and reducing nutrient loss. This study hopes to promote high-quality and efficient production of kiwifruit and promote the development of green agriculture.
