1、Reduced Fertilization and Magnesium Supplementation: Modulating Fruit

In a three-year experiment, two fertilizer treatments were implemented: a farmer fertilizer practice (FP) and an NPK reduction plus foliar Mg fertilizer (OPT + fMg).

2、Magnesium fertilization promotes flavor balance and phenolic

Mg fertilization significantly increased pomelo yield, by 23.9 % under soil application and 31.7 % under foliar spraying.

3、Effects of Application Methods of Magnesium Fertilizer on Nutritional

The experiment aims to investigate the effects of magnesium fertilizer application strategies on the nutritional status, yield and quality of pomelo, and the results may provide a theoretical basis for scientific application of magnesium fertilizer in pomelo production.

4、

In conclusion, if the risk of soil nitrate leaching is not considered, the recommended Mg application rate is 35 kg MgO ha⁻¹ yr⁻¹; otherwise, it is 70 kg MgO ha⁻¹ yr⁻¹.

To prevent fruit drop and extend picking season it is recommended to spray 18 ppm 2-4-D combined with 1% – 2% Multi-K, with an appropriate surfactant. Need more information about growing pomelos? You can always return to the pomelo tree fertilizer .

镁肥施用方式对蜜柚营养状况、产量和品质的影响

不同镁肥施用方式均可以改善蜜柚叶片和果实的营养状况,提高蜜柚光合作用、产量和品质;叶面施镁与土施镁肥效果相当,叶面喷施4%Mg SO4·7H2O是蜜柚重要的补镁措施。

Reduced Fertilization and Magnesium Supplementation: Modulating Fruit

Based on our previous farmer surveys and an exploration of the nutrient demand patterns of Guanxi honey pomelo trees, we identified two obstacles in most pomelo orchards in Pinghe: excessive fertilizer application and commonly occurring Mg deficiency.

Optimized fertilization and fruit load regulate yield, quality, and

Mineral nutrients play a crucial role in ensuring consistent yields of citrus trees; however, the effects of fertilization management and fruit load level on yield and nutrient uptake in pomelo trees remain unclear.

How Do You Fertilize For Pomelo

To determine the best fertilizer for pomelo, it’s important to consider the soil type and nutrient content, as well as the type of pomelo tree you’re growing.

How to Fertilize Your Pomelo Tree Effectively?

For Pomelo trees, a balanced ratio like 6-6-6 or 8-8-8 is commonly recommended, providing equal parts of nitrogen, phosphorus, and potassium. This balance supports all aspects of growth, from lush foliage to a strong root system and plentiful fruit production.

The amount and frequency of magnesium fertilizer application for bearing pomelo trees should be determined based on soil test results, tree growth conditions, climatic factors, and recommendations from local agricultural departments. Magnesium is an essential micronutrient for plant growth, playing a critical role in root development, photosynthesis, protein synthesis, and energy conversion.

1. Determine Fertilization Requirements

First, conduct a soil test to assess its magnesium content. This can be done using professional soil testing kits or by contacting local agricultural service departments for on-site analysis. Based on the results, decide whether additional magnesium is needed and the appropriate dosage.

2. Choose the Type of Magnesium Fertilizer

Various magnesium fertilizers are available, including magnesium sulfate, magnesium chloride, and magnesium nitrate. Consider the following when selecting:

• Fertilizer Composition: Priority should be given to products with high magnesium concentration, as low-concentration magnesium may not be fully absorbed by plants.
• Solubility: The fertilizer must dissolve well to ensure root uptake.
• Stability: Soil stability is crucial to prevent magnesium loss due to decomposition.

3. Timing of Application

Magnesium fertilizer is typically applied alongside major nutrients like nitrogen and phosphorus, as magnesium works synergistically with these elements. if soil magnesium levels are low, separate applications may be necessary to ensure adequate supply.

4. Application Methods

Methods vary by fertilizer type and crop needs:

• Base Fertilization: Mix magnesium fertilizer into the soil before planting as a long-term nutrient source.
• Topdressing: Apply magnesium periodically during growth, adjusting timing based on soil tests and tree health. Apply during active growth phases (e.g., spring) or slower periods (e.g., autumn).

5. Precautions

• Avoid Overapplication: Excessive magnesium can lead to toxicity and hinder growth. Follow labeled dosages strictly.
• Do Not Mix with Alkaline Substances: Combining magnesium fertilizers with alkaline materials reduces effectiveness.
• Environmental Factors: High temperatures and drought may reduce magnesium availability; adjust application plans accordingly.

6. Comprehensive Management

To ensure adequate magnesium nutrition for bearing pomelo trees, integrate the following practices:

• Proper Irrigation: Maintain moist soil to aid root absorption of water and nutrients.
• Pruning and Training: Regularly prune trees to improve airflow, reduce disease risk, and enhance fruit quality and yield.
• Pest and Disease Control: Minimize nutrient competition by monitoring and managing pests and diseases effectively.

magnesium fertilization for bearing pomelo trees requires careful consideration of multiple factors. Scientific application and integrated management ensure healthy growth, improved fruiting rates, and superior fruit quality.
