Combined Application of Calcium

To improve soil P fertility and maintain crop yield, large amounts of P fertilizers were applied (Withers et al. 2014). However, P fertilizer is mostly obtained from mined high-grade phosphate rock, which is a limited and non-renewable resource.

Litchi trees, as tropical fruit crops, have extremely high demands for soil nutrients and moisture. Calcium-magnesium-phosphate fertilizer is a critical nutrient source, providing essential elements such as phosphorus and calcium that are vital for the growth and fruit development of litchi trees. Below is a guide on the correct application of this fertilizer to ensure healthy tree growth.

1. Understanding the Nutrient Needs of Litchi Trees

1. Nitrogen (N): Litchi trees require significant nitrogen to support rapid growth, flowering, and fruiting. Nitrogen fertilizers promote leaf growth and enhance photosynthetic efficiency.
2. Phosphorus (P): Phosphorus is a key component of cellular ribosomes, crucial for root development and flower bud differentiation. Phosphate fertilizers strengthen root absorption capacity and accelerate fruit maturation.
3. Potassium (K): Potassium regulates water balance, improves disease resistance, and enhances fruit quality.
4. Calcium (Ca): Calcium directly impacts stem strength and fruit firmness. Calcium deficiency makes fruits prone to mechanical damage.
5. Magnesium (Mg): Magnesium is involved in chlorophyll synthesis. Magnesium deficiency reduces photosynthetic efficiency, hindering overall plant growth.

2. Selecting the Right Calcium-Magnesium-Phosphate Fertilizer

1. Fertilizer Type: Common forms include solid granules, liquids, and powders. Choose based on soil conditions and application goals.
2. Fertilizer Composition: High-quality products should contain high proportions of phosphorus, calcium, and trace elements like iron (Fe) and zinc (Zn).
3. Fertilizer Purity: Ensure the fertilizer is free from harmful substances to safeguard plant health.

3. Application Methods

1. Base Fertilization: Before planting, evenly spread the fertilizer over the soil surface and incorporate it into the soil. This provides sustained nutrients throughout the year.
2. Topdressing: During the growing season, especially during fruit enlargement, apply additional fertilizer based on the tree’s needs. Topdressing is best done in the morning or evening to minimize evaporation losses.
3. Foliar Spraying: For micronutrients poorly absorbed by roots, apply a foliar spray directly onto litchi leaves to improve nutrient uptake efficiency.

4. Precautions for Fertilization

1. Avoid Overapplication: Excessive phosphorus or calcium can harm plants, causing overgrowth or yellowing leaves. Follow the principle of "moderate application."
2. Soil Testing: Conduct pre-fertilization soil tests to analyze nutrient levels and pH, enabling precise fertilization.
3. Balanced Fertilization: Combine calcium-magnesium-phosphate fertilizers with organic fertilizers and microbial fertilizers to ensure comprehensive soil nutrient supply.

5. Post-Fertilization Management

1. Irrigation: Water immediately after fertilization to dissolve nutrients and facilitate root absorption.
2. Ventilation: Maintain proper airflow to reduce fertilizer odor effects on plants.
3. Monitor Plant Response: Observe for signs of root burn or other adverse reactions. Adjust fertilization strategies if needed.

proper application of calcium-magnesium-phosphate fertilizer is vital for the healthy growth of litchi trees. By understanding their nutritional needs, selecting appropriate fertilizers, using scientific application methods, and implementing post-fertilization care, litchi trees can achieve high-quality, productive results.
