Sugar orange is a tropical and subtropical fruit tree renowned for its sweet, juicy fruit. Proper fertilization and management during July to September are critical to ensuring healthy growth and improving yield. Below are detailed fertilization and management recommendations:

1. Base Fertilization

• First application: Conduct the initial fertilization in spring (March to April) or autumn (September to October) using organic fertilizers such as compost or green manure. These provide essential nutrients for the sugar orange throughout the year.
• Pre-flowering stage: Apply a fast-acting fertilizer (e.g., diammonium phosphate, urea) before flowering (typically May to June) to promote bud differentiation and flower development.
• Fruit enlargement stage: During fruit expansion (usually June to August), increase phosphorus and potassium fertilizers based on tree size and soil fertility to enhance ripening and coloration.

2. Topdressing Management

• Spring shoot growth: Apply nitrogen fertilizer in April to May to support new shoot and leaf development.
• Summer drought: Supplement with appropriate water and nutrients during hot, dry periods to prevent dehydration and nutrient loss.
• Fruit enlargement: Continue phosphorus and potassium applications to meet fruit growth demands. Limit nitrogen use to avoid compromising fruit quality.
• Fruit coloring: From August to September, adjust phosphorus and potassium doses based on tree condition and soil fertility to improve coloration and quality.

3. Pruning and Training

• Dormant season pruning: Trim in spring (March to April) or autumn (September to October) to remove diseased, weak, or crossing branches. This ensures canopy ventilation, reduces pest risks, and optimizes sunlight exposure.
• Structural adjustments: Thin, shorten, or shape branches as needed to balance canopy structure, promote even light distribution, and enhance photosynthesis.

4. Pest and Disease Control

• Monitoring: Regularly inspect trees and promptly address pests/diseases through spraying fungicides/insecticides or removing affected branches.
• Cultural practices: Reduce pest risks by maintaining proper irrigation, fertilization, and canopy airflow.

5. Irrigation and Drainage

• Water management: Adjust irrigation/drainage based on climate and soil moisture to keep soil moist but well-drained, preventing root diseases.
• Drought response: Increase irrigation frequency and volume during dry seasons to sustain growth needs.

6. Soil Management

• Soil testing: Regularly check soil pH and nutrient levels to refine fertilization plans, maintaining optimal acidity and fertility.
• Soil improvement: For sandy soils, incorporate organic matter and lime to enhance structure and fertility.

By following these strategies, sugar orange growth and fruit quality can be significantly improved. Additionally, monitor plant health and environmental changes, adaptably refining management practices as needed.
