The selection and application of fertilizers are critical for the healthy growth of young orange trees. Below is a detailed guide on choosing appropriate fertilizers and methods for citrus saplings:

I. Fertilizer Selection

1. Organic Fertilizers

   • Sources and Characteristics: Organic fertilizers include compost, well-decomposed animal manure (e.g., cattle or chicken manure), green manure, and biogas residue. These materials are rich in essential nutrients like nitrogen (N), phosphorus (P), potassium (K), and microelements. They also improve soil structure and increase organic matter content.
   • Application Method: Spread organic fertilizers evenly around the base of the tree to reduce water evaporation and promote microbial decomposition.

2. Chemical Fertilizers

   • Types and Functions: Chemical fertilizers, such as urea, diammonium phosphate, and potassium chloride, provide rapid nutrient uptake. They are suitable when organic fertilizers are unavailable.
   • Timing: Apply chemical fertilizers during early growth stages or in autumn, when the tree’s nutritional demands are higher.

3. Compound Fertilizers

   • Advantages: These fertilizers contain multiple nutrients, meeting the needs of young orange trees at different growth stages while improving nutrient utilization efficiency.
   • Recommendations: Compound fertilizers are ideal for citrus trees, especially during juvenile phases and fruiting periods.

II. Fertilization Methods

1. Base Fertilization

   • Timing: Apply before planting or in autumn after leaf litter.
   • Dosage: Use 50–100 kg of compound or organic fertilizer per mu (0.067 hectares) based on soil fertility and tree needs.
   • Notes: Bury fertilizer deeply to avoid direct root contact, which could cause root burning.

2. Top-Dressing (Supplementary Fertilization)

   • Timing: Apply during peak growth periods, such as bud sprouting in spring or before/after flowering.
   • Dosage: Use 20–40 kg of compound fertilizer per mu, adjusted according to tree health and soil conditions.
   • Methods: Apply via trench, hole, or foliar spraying to ensure even distribution.

3. Foliar Fertilization

   • Suitable Stages: Apply during rapid fruit expansion or flower bud differentiation.
   • Method: Use specialized foliar fertilizers or dilute solutions and spray directly onto leaves.
   • Notes: Avoid spraying during hot weather to prevent leaf damage.

III. Key Considerations

1. Fertilizer Type: Choose fertilizers based on the tree’s growth stage and soil conditions.
2. Dosage and Frequency: Over- or under-fertilization can harm the tree. Adjust amounts based on specific needs.
3. Timing and Techniques: Follow proper schedules and methods to avoid damaging the trees.

rational fertilization is key to healthy orange tree development. By selecting appropriate fertilizers and applying them correctly, you can significantly improve yield and fruit quality.
