BASICS OF FOLIAR APPLICATION

It is important to apply foliar fertilizer at the proper growth stages. Foliar applications should be timed to provide needed nutrients during the yield determining growth stages. Multiple, low rate applications may show the most favorable crop yield responses. Monitor crop growth on a weekly or even

As a fruit tree, Prunus salicina (plup leaf plump) requires careful foliar fertilization before flowering to enhance fruit quality and yield. Selecting the appropriate foliar fertilizer is critical for promoting growth, improving disease resistance, and optimizing fruit characteristics. Below are guidelines for choosing and applying foliar fertilizers before flowering:

I. Selection of Foliar Fertilizers

1. Nitrogen Fertilizers: Nitrogen is essential for leaf growth and photosynthesis. Applying nitrogen-rich foliar fertilizers before flowering stimulates shoot development and increases leaf density, ensuring adequate nutrition during the flowering period.
2. Phosphorus Fertilizers: Phosphorus promotes root growth, disease resistance, and fruit quality. Moderate phosphorus-containing foliar fertilizers aid nutrient absorption, flower bud differentiation, and early fruit development.
3. Potassium Fertilizers: Potassium regulates water balance, enhances stress tolerance, and supports physiological processes during flowering. Proper potassium application improves pollen tube elongation and pollination success while boosting disease resistance.
4. Micronutrients: Iron, zinc, magnesium, and other microelements are vital for enzyme activity and photosynthesis. Deficiencies can stunt growth and reduce fruit quality. Supplementing these micronutrients in foliar fertilizers prevents deficiencies and ensures optimal development.

II. Timing and Application Methods

1. Timing: Apply foliar fertilizers in late spring to early summer when temperatures rise and sunlight is sufficient. This maximizes absorption and effectiveness.
2. Methods:
   • Immersion: Dilute fertilizer in water and soak leaves for 5–10 minutes. Suitable for large orchards.
   • Spraying: Use a sprayer to evenly apply diluted fertilizer. Avoid overapplication to prevent damage.
   • Drip Irrigation: Directly apply fertilizer solution to leaves. Ideal for small-scale or container-grown trees.

III. Precautions

1. Dosage: Adjust based on tree health and soil fertility. A typical dose is 5–10 kg of compound fertilizer per mu (~0.067 hectare), split into two applications 7–10 days apart.
2. Concentration: Follow product instructions or expert advice to avoid overconcentration, which may cause phytotoxicity.
3. Environmental Conditions: Avoid strong winds or extreme heat during application to ensure absorption.
4. Safety: Wear protective gear to prevent skin contact or inhalation of dust. Dispose of packaging responsibly to avoid environmental contamination.

IV. Supplementary Practices

1. Pruning: Timely pruning before and after fertilization improves air circulation, reduces pest risks, and fosters healthy shoot growth.
2. Pest and Disease Control: Monitor trees closely during fertilization. Use biological or chemical pesticides judiciously to minimize residues and harm.

Tailor foliar fertilizer selection and application to Prunus salicina’s nutritional needs and soil conditions. Combining scientific fertilization with proper management practices enhances yield, fruit quality, and sustainable orchard productivity.
