Abstract
Objective This study aims to explore the effects of different fertilization modes on the dynamic regulation of nutrient distribution，main fruit quality and yield of Camellia oleifera，thus seeking suitable cultivation measures to protect fruit and promote yield of Camellia oleifera，and providing theoretical reference for the improvement of cultivation technology of Camellia oleifera. Method The 13-year-old girdled camellia oleifera was used as experimental material.Five treatments，single application of compound fertilizer in December（A1），single application of compound fertilizer in March（A2），single application of organic fertilizer in December（A3），combined application of organic fertilizer and compound fertilizer in December（A4），and organic fertilizer in December + compound fertilizer in March（A5），were set up.The contents of N，P and K in camellia oleifera and the economic quality and yield of the fruit at ripening stage were measured and analyzed. Result （1）Applying compound fertilizer increased the fruit volume，weight and seed extraction rate of girdled Camellia oleifera，and significantly improved the fruit yield and oil production；（2）The decrease of fruit set rate from March to May was significantly higher than that from May to October，and the application of compound fertilizer after ring cutting significantly improved the fruit set rate of Camellia oleifera；（3）The fertilization mode has a significant impact on the contents of N，P and K in leaves，fruits and roots.After girdling，applying compound fertilizer in December of the current year and March of the following year has no obvious difference in the influence on the nutrient of the tree.（4）At fruit expansion stage，P in leaves and N in roots increased.At the ripening stage，N nutrient content in leaves increased.From the young fruit stage to the mature stage，K nutrients in the fruit continued to accumulate；（5）The results of principal component analysis showed that fruit quality and yield were significantly dispersed under different fertilization patterns.Fruit biomass and economic traits were positively correlated with yield，and negatively correlated with fruit shape index. Conclusion After girdling Camellia oleifera，applying compound fertilizer is the best practice..The application of compound fertilizer in December is beneficial to the accumulation of fruit yield，and the application in March of the next year is beneficial to the improvement of fruit quality.
