1、Fruit tree before bagging

Foliar fertilizers like Fifan, Sdeco, and Green are also recommended for foliar application. During the young fruit stage, micro-nutrient fertilizers like Stedokop can be used to address iron deficiency-related yellowing.

2、Guide to Foliar Fertilization: Best Practices, Dosages, and Benefits

Most foliar fertilizers can be tank-mixed with pesticides, reducing labor and application costs. Some formulations also improve pesticide adhesion and uptake through surfactants or organic chelators.

3、Foliar spraying of potassium sulfate during fruit development

In this study, three different potassium fertilizers and one water (F1: 0.65% KNO 3, F2: 0.88% KH 2 PO 4, F3: 0.56% K 2 SO 4, and F4: water) were sprayed on Citrus reticulata cv. Nanfeng at cell division, cell expansion, fruit ripening, and throughout fruit developmental stages, respectively.

4、Foliar application of bioorganic fertilizer enhances plant nutrients

Foliar Bio-organic fertilizer (BIOF) enhanced soil properties including soil enzymes, except soil P and pH. The foliar application has mitigated the uptake of the cadmium and iron to the plants. Foliar organic fertilizer increased yield parameters, including fruit size and numbers.

Preharvest Fruit Bagging for Better Protection and Postharvest Quality

Of several such alternatives, preharvest fruit bagging has emerged as one of the best approaches in various parts of the world (Sharma et al., 2014a). In this technique, individual fruit or a fruit bunch is bagged on the tree for a specific period to get the desired results.

Pretreatment of fruit trees before bagging and its solution

Calcium supplementation is very important for apples. The use of six trace element fertilizers, such as 5,000 to 6,000 times for Strecopot, 6000 to 2000 times for top green, can promote the absorption of calcium fertilizers and a large number of elements.

In the cultivation of fruit trees, fruit enlargement is critical for improving yield and quality. Foliar fertilization is an efficient way to supplement nutrients, providing plants with essential elements quickly and promoting fruit growth. Below are some commonly used foliar fertilizers, their application methods, and benefits for fruit enlargement.

1. Potassium Dihydrogen Phosphate (KH₂PO₄)

• Mechanism: This popular foliar fertilizer contains phosphorus and potassium, both vital for plant growth and fruit development. Phosphorus promotes root development and disease resistance, while potassium enhances stress tolerance and improves fruit quality.
• Application: Dilute the appropriate amount of potassium dihydrogen phosphate and spray evenly on leaves using a sprayer. Apply every 7–10 days for 2–3 consecutive times.
• Precautions: Avoid overapplication to prevent fertilizer damage. Apply on cloudy days or in the evening to reduce heat stress from sunlight.

2. Seaweed Extract

• Mechanism: Rich in microelements and growth regulators, seaweed extract stimulates plant growth, boosts photosynthesis, and improves fruit yield and quality.
• Application: Dilute seaweed extract according to instructions and spray directly onto leaves, avoiding contact with fruits.
• Precautions: Test on a small scale first, as seaweed extract may not suit all plant types.

3. Amino Acid Chelated Zinc

• Mechanism: This trace element fertilizer is rapidly absorbed by plants, promoting growth and fruit development.
• Application: Follow product instructions for dilution and use.
• Precautions: Avoid mixing with alkaline substances, which may reduce zinc absorption.

4. Borax (Sodium Borate)

• Mechanism: A broad-spectrum plant growth regulator, borax promotes sugar accumulation, enhancing fruit quality and taste.
• Application: Dilute borax solution and spray evenly on leaves.
• Precautions: Test on a small scale first, as borax may cause phytotoxicity in some plants.

5. Humic Acid-Based Fertilizers

• Mechanism: These fertilizers improve soil structure, water retention, and nutrient-holding capacity, fostering plant growth and fruit enlargement.
• Application: Mix humic acid-based fertilizers with water at recommended ratios and apply around the root zone.
• Precautions: Avoid mixing with alkaline substances to maintain effectiveness.

foliar fertilization is an efficient and convenient way to support fruit enlargement in fruit trees. Select fertilizers based on specific plant needs and growth stages, and combine different types thoughtfully to achieve optimal nutritional effects.
