Navel oranges are a nutrient-rich fruit, containing abundant vitamins C and A, dietary fiber, and other essential nutrients. during cultivation, applying calcium and magnesium fertilizer is critical to ensuring healthy growth. Below are recommendations for the optimal timing of calcium and magnesium fertilization for navel oranges:

1. Growth Phase: Navel oranges primarily grow in spring and autumn. During these seasons, root systems develop gradually, and nutrient demands increase. Applying calcium and magnesium fertilizer during this phase is essential.

2. Flowering Stage: Navel oranges typically bloom in spring. Flowers require ample nutrients to thrive, and calcium and magnesium fertilizer can enhance flower quality and promote fruit development.

3. Fruit Maturation Period: Fruits mature in autumn, when they demand significant nutrients to ensure quality. Calcium and magnesium fertilizer improves fruit traits and increases yield.

4. Dormancy Period: Dormancy occurs in winter, when roots enter a resting state and nutrient needs decline. Applying fertilizer during this phase is inappropriate.

5. Growing Season: Spring, summer, and autumn constitute the main growing season. Roots actively develop during this time, increasing nutrient demands. Fertilization with calcium and magnesium is crucial.

6. Peak Growth Phase: Summer marks the peak growth period, characterized by rapid root development and heightened nutrient requirements. Fertilization is highly recommended during this stage.

7. Late Growth Phase: In autumn, when fruits mature, nutrient demands decrease. Applying fertilizer is not advisable during this period.

8. Early Growth Phase: Spring represents the early growth stage, when roots begin developing and nutrient needs rise. Fertilization is essential here.

9. Mid-Growth Phase: Summer is the mid-growth phase, marked by accelerated root growth and increased nutrient demands. Fertilization remains critical.

10. Post-Growth Phase: By autumn, fruits are fully mature, and nutrient requirements diminish. Fertilization is unnecessary at this stage.

The best times to apply calcium and magnesium fertilizer are during the growth phase and flowering stage, as these periods correspond to peak nutrient demands. Proper fertilization ensures efficient nutrient absorption and promotes healthy growth and development.
