Different foliar fertilizer adjuvants can improve the quality of fresh grapes, and each treatment significantly increased the content of soluble solids in the fruit.

3、Grapes Fertilizer Management

The most commonly used methods of fertilization are top dressing, foliar fertilization, and fertigation (injection of water-soluble fertilizers inside the irrigation system).

4、How to Prevent and Control Pests in Grape Foliar Fertilization

effective pest management in grape foliar fertilization requires integrating preventive and curative approaches. Scientific management and balanced fertilization are key to ensuring healthy grape growth.

Foliar Fertilization of Grapevines: What We Know and Don’t Know

Applying fertilizers or plant nutrients to foliage has a long history, and there is an extensive number of papers published on the subject.

Effects of Foliar Application of Magnesium Fertilizer on Photosynthesis

Efforts to increase grape yields have focused on using nitrogen, phosphorus, and potassium fertilizers, often causing unintended magnesium (Mg) deficiencies.

Effects of foliar fertilizer additives on grape fruit quality and

It provides an efficient and low-cost foliar fertilizer adjuvant application scheme for grape cultivation in the Hexi Corridor region, which has important practical significance for improving the economic benefits and sustainable development of the fresh grape industry.

Techniques and Management of Foliar Fertilization for Grapes

I. Introduction Grapes are one of the world’s most important fruits, with a long history of cultivation and diverse varieties. Foliar fertilization is a modern approach to nutrient application, where fertilizers are sprayed directly onto grape leaves to supply essential nutrients, enhance plant growth, and increase yields. This article provides a detailed overview of foliar fertilization techniques and management practices for grapes.

II. Functions of Foliar Fertilization for Grapes

1. Nutrient Supplementation: Foliar fertilizers directly provide essential elements such as nitrogen (N), phosphorus (P), and potassium (K) to grape leaves, improving the efficiency of nutrient absorption.
2. Growth Regulation: These fertilizers regulate plant growth rates, promote flower bud differentiation, and prevent flower or fruit drop.
3. Quality Improvement: Foliar fertilization enhances fruit quality, including sugar content, color, and taste.
4. Resource Conservation: It reduces the use of chemical fertilizers, minimizing environmental pollution.

III. Types of Foliar Fertilizers for Grapes

1. Water-Soluble Fertilizers: Examples include urea and potassium dihydrogen phosphate, suitable for all grape varieties.
2. Oil-Soluble Fertilizers: Such as boric acid and zinc sulfate, tailored for specific grape varieties.
3. Amino Acid-Based Fertilizers: Like aspartate and betaine, used for grapes with special nutritional needs.

IV. Application Methods for Grape Foliar Fertilizers

1. Dilution: Dilute fertilizers into water solutions according to specified concentrations and types.
2. Spraying: Apply on calm, sunny days, ensuring even coverage of leaves. Avoid overapplication to prevent leaf burn.
3. Timing: Optimal spraying times are early morning or evening, avoiding peak heat.
4. Dosage: Adjust fertilizer amounts based on grape variety, growth stage, and soil conditions.

V. Management of Grape Foliar Fertilization

1. Timing: Apply during the growing season, typically once in spring (before budding) and autumn (before fruit maturation).
2. Dosage: Control amounts based on plant health and soil fertility. A general recommendation is 5–10 kg of compound fertilizer per mu (0.067 hectares).
3. Methods: Use drip irrigation or sprinkler systems to minimize fertilizer loss.
4. Effectiveness: Results appear quickly (within 2–3 days), but avoid overfertilization to prevent damage.

VI. Precautions for Grape Foliar Fertilization

1. Avoid Overapplication: Excessive use may cause leaf burn or root damage.
2. Prevent Repetition: Do not apply the same fertilizer repeatedly within a short period, as this may disrupt plant growth.
3. Environmental Considerations: Avoid spraying during extreme weather (e.g., high winds or heat).
4. Variety-Specific Needs: Choose fertilizers based on the unique requirements of different grape varieties.

Foliar fertilization for grapes is a comprehensive technique that requires scientific application based on growth patterns and soil conditions. By adopting proper methods and management practices, farmers can boost yields, improve fruit quality, and contribute to sustainable agricultural development.
