The supplementation of macroelements is critical for the healthy growth of strawberry seedlings. During plant development, essential nutrients such as nitrogen (N), phosphorus (P), and potassium (K) play vital roles. These elements not only influence photosynthesis and respiration but also significantly impact fruit quality and yield. rational foliar application of macroelements is crucial for promoting rapid growth and efficient production in strawberry seedlings.

I. The Role of Macroelements

1. Nitrogen Fertilizer: Nitrogen is a key component of proteins, driving plant growth and development. It enhances chlorophyll synthesis, improves photosynthetic efficiency, and provides energy for rapid growth. Additionally, nitrogen strengthens disease resistance, reducing the incidence of pests and diseases.

2. Phosphorus Fertilizer: Phosphorus activates enzymes involved in energy metabolism, nucleic acid synthesis, and cell division. It promotes root development, enhancing water and nutrient absorption, which boosts growth speed and stress resistance. Phosphorus also accelerates fruit maturation and improves quality.

3. Potassium Fertilizer: Potassium improves cold and drought tolerance while enhancing disease resistance. It stimulates sugar accumulation in fruits, improving taste and quality. Additionally, potassium boosts photosynthesis and respiration, increasing growth rates and yields.

II. Optimal Timing for Foliar Application

1. Spring: A critical growth phase, spring offers ideal conditions (warmer temperatures, ample light) for photosynthesis. Applying nitrogen during this period promotes leaf expansion and photosynthetic capacity. Phosphorus supports root development, enhancing nutrient uptake.

2. Summer: High temperatures and rapid growth increase nutrient demands. Nitrogen aids fruit expansion and quality, while phosphorus and potassium strengthen disease resistance during the peak pest season.

3. Autumn: As growth slows, macroelements help accumulate nutrients for winter dormancy. Nitrogen improves sugar content and storage life, while phosphorus and potassium reduce pest risks.

4. Winter: Low temperatures reduce growth, but phosphorus and potassium remain essential for pest prevention. Minimal nitrogen supports root recovery and nutrient reserves.

III. Precautions

1. Dose and Concentration Control: Excessive fertilization risks root burn or toxicity. Adjust amounts based on growth stages and soil conditions.

2. Application Methods: Use appropriate fertilizer types (e.g., organic over synthetic) and methods (foliar spray vs. root application) to maximize efficiency.

3. Environmental Factors: Avoid midday applications in hot weather to prevent leaf scorch. Choose morning/evening for cool periods. Steer clear of rainy days to prevent runoff and pollution.

IV. Conclusions and Recommendations

1. Rational Fertilization: Tailor nutrient amounts to growth stages and soil needs. Prefer mild organic fertilizers for long-term health.

2. Scientific Management: Combine foliar and root applications. Time fertilization to align with temperature, humidity, and wind conditions.

3. Continuous Monitoring: Observe plant health and soil status regularly. Address issues like stunted growth or yellowing leaves by adjusting fertilization strategies.

macroelement supplementation in strawberries requires systematic planning based on growth stages and environmental factors. Scientific fertilization practices ensure healthy plants and high-yield harvests.
