The impact of foliar applications using N levels (0, 0.25%, 0.5%, and 1%) and B levels (0, 0.1%, 0.25%, and 0.5%) following a randomized block design with three replications was studied.

Da Long Qie, scientifically known as Solanum melongena, is a tropical and subtropical perennial herbaceous plant native to Central and South America. It is renowned for its vibrant fruit, often referred to as "dragon eyes," and is one of the world's important fruit trees. In agricultural production, cultivation management of Da Long Qie is critical, and the use of foliar fertilizers is a key measure to enhance plant growth rates and fruit quality.

I. Selection of Foliar Fertilizers

1. Nitrogen Fertilizer

Nitrogen is a fundamental element for plant growth and development, playing a crucial role in promoting leaf growth and flower-fruit formation. During the cultivation of Da Long Qie, appropriate application of nitrogen fertilizer can boost leaf expansion and photosynthetic efficiency, thereby benefiting fruit development. excessive nitrogen use may lead to spindly growth and reduced fruit quality. foliar fertilizers with moderate nitrogen content should be selected to avoid overapplication.

2. Phosphorus Fertilizer

Phosphorus promotes root development, enhances disease resistance, and stimulates flower bud differentiation, improving fruit setting rates. In Da Long Qie cultivation, proper phosphorus application strengthens plant resilience and supports flower-fruit formation. excessive phosphorus may disrupt nutritional balance, so dosage should be carefully controlled.

3. Potassium Fertilizer

Potassium improves stress resistance, increases fruit firmness and sweetness, and regulates water metabolism to reduce disease incidence. For Da Long Qie, appropriate potassium use enhances fruit quality and extends shelf life. Nonetheless, excessive potassium may hinder normal growth, requiring balanced application.

4. Micronutrients

Micronutrients such as boron, zinc, and iron are vital for plant health. They activate enzymes, optimize nutrient uptake, and boost overall plant resilience and yield. Supplementing micronutrients during Da Long Qie cultivation supports robust growth.

II. Techniques for Foliar Fertilization

1. Timing: Apply foliar sprays based on Da Long Qie’s growth habits and climate. Spring and autumn are ideal due to mild temperatures and active growth.

2. Dilution Ratio: Follow product instructions for dilution. Typically, a 1:1000–1:2000 ratio prevents fertilizer burn.

3. Uniform Application: Use a sprayer to evenly coat leaves, avoiding fruit contact to preserve quality. Ensure full leaf coverage for maximum absorption.

4. Timely Supplementation: Combine foliar sprays with other fertilization methods. Apply fast-acting fertilizers during early growth or flowering stages to meet plant demands.

5. Precautions: Monitor plants for signs of fertilizer damage (e.g., yellowing, wilting). If observed, halt application and take corrective measures. Coordinate with pesticides and other fertilizers to prevent chemical interactions.

foliar fertilization for Da Long Qie should align with specific growth stages and soil conditions. Proper use enhances growth, fruit quality, and yield. Integrating these practices with other agricultural techniques ensures efficient cultivation.
