1、Optimal Timing for Applying Phosphate Fertilizer to Shatang Orange

In cultivating Shatang orange, rational fertilization management is crucial to enhancing fruit quality and yield. Phosphate fertilizer, as a key component of nutrients, plays a vital role in its growth.

2、Comprehensive evaluation of using mineral and bio phosphorus

Two experiments were achieved over 2020/2021 and 2021/2022 seasons on 13 – year-old Valencia orange (Citrus sinensis L. Osbeck) trees budded on Folka Marina orange rootstock to study the effect of mineral and bio phosphorus fertilization on yield and quality characters of summer orange.

3、China GPC's NutriMagic Fertilizer Helps Shatang Oranges in Qingyuan

From the revival of an "abandoned tree" to the harvest of high-quality fruits in an orchard, as the fruit industry enters the stage of quality competition, the importance of scientific fertilization and soil management has become increasingly prominent.

4、Evaluation of different fertilization strategies on orange

The effects of timing and modes of nutrient application on yield, vegetative and nutritional status of 30-year old ‘Valencia late’ sweet orange trees [Citrus sinensis (L.) Osbeck] grafted on sour orange (C. aurantium L.) were evaluated.

Autumn Shoot Fertilizer: Cultivation Results The mother tree is the key point of fertilization in a year and should be 30% to 40% of the total amount of fertilization in the whole year.

Orange Tree Care: Harnessing Smart Agriculture for Optimal Growth

Key aspects of orange tree care include planting, watering, fertilization, pruning, pest control, and harvesting. Incorporating Smart Agriculture techniques can enhance each of these aspects, ensuring healthier trees and higher yields.

In August, Shatang Tang put autumn shoots

To date, the area under Shatang orange cultivation in Huazhou has reached 3,000 acres. Due to its adaptability to various climates, Shatang orange can be grown across different regions, but each area requires tailored cultivation techniques.

After planting and before fruiting, the shoots are placed four times a year. When the new shoots grow to 5-6cm, the excessive weak shoots are removed in time, which will help increase the yield.

Is Foliar Fertilization Still Necessary for Shatang Oranges in May? Why?

This helps refine fertilization strategies and ensures balanced nutrition. Integrated Fertilization: Combine foliar fertilizers with other methods (e.g., base fertilizers, topdressing, organic fertilizers) to create a diversified nutrient supply system.

Shatang orange is native to Guangdong Sihui and is a famous local variety in Guangzhou and Sihui. It has wide adaptability, strong stress resistance, high yield and stable yield, good fruit quality, fruity orange yellow, sweet, thin and peelable, on the market.

After pruning and harvesting Shatang oranges, proper fertilization management is crucial to promote plant recovery, growth, and improve fruit quality. Below is a detailed guide on how to apply fertilizers effectively post-harvest.

I. Fertilization Principles

1. Balanced Nutrition: Shatang oranges require significant amounts of nitrogen (N), phosphorus (P), and potassium (K), but nutrient ratios vary at different growth stages. Adjust fertilizer composition based on plant health and soil test results.

2. Prioritize Organic Fertilizers: Organic materials like animal manure and compost provide comprehensive nutrients and beneficial microorganisms. They enhance soil structure, water retention, and fertility.

3. Moderate Application: Over-fertilization can lead to soil salinization or root burn, while under-fertilization stunts growth and reduces fruit quality. Apply fertilizers in appropriate amounts.

4. Optimized Formulas: Tailor fertilizer types and ratios to Shatang orange’s growth habits and soil conditions. For example, increase phosphorus in sandy soils and potassium in clayey soils.

5. Regular Application: Fertilization is an ongoing process. Adjust plans seasonally and according to plant needs to ensure continuous nutrient supply.

II. Fertilization Methods

1. Top-Dressing:

   • Timing: Apply during peak growth periods when nutrient demand is high.
   • Methods:
     • Foliar Spraying: Dissolve fertilizers in water and spray directly onto leaves for rapid absorption.
     • Root-Zone Top-Dressing: Drip or pour diluted fertilizer solutions near roots to boost nutrient uptake.

2. Base Fertilization:

   • Timing: Apply in spring or autumn as part of long-term care.
   • Materials: Use organic fertilizers (e.g., manure, compost) or specialized fruit-tree formulas.
   • Dosage: Apply 5–10 kg per plant, adjusted for plant size and soil type.

3. Mixed Fertilization:

   • Combine organic and synthetic fertilizers to improve efficiency and reduce environmental impact. Ensure compatibility to avoid adverse reactions.

III. Key Considerations

1. Prevent Nutrient Runoff:

   • Minimize fertilizer loss, especially during rainy seasons. Use drainage ditches or mulch covering to retain nutrients.

2. Safety Measures:

   • Wear protective gear to avoid skin/eye contact with chemicals. Prevent fertilizer splashes on clothing or equipment.

3. Avoid Over-Fertilization:

   • Excess nutrients harm plants and fruit quality. Stick to recommended dosages.

4. Clean Up Residues:

   • Remove leftover fertilizer to prevent pollution. Dispose of residues via burial or incineration if necessary.

Post-harvest fertilization is vital for Shatang orange recovery and fruit quality. By combining organic and synthetic fertilizers wisely, ensuring balanced nutrition, and adhering to safety practices, growers can optimize plant health while minimizing environmental risks. Regular monitoring and adjustments based on soil and plant conditions are key to success.
