Papaya topdressing methods:
1. Before sprouting (late March to early April), apply 130 g of urea and 400 g of ternary compound fertilizer per tree in holes or trenches.
2. Two weeks before and after flowering, spray once each time a mixture of 0.3% urea, 1% superphosphate, and 0.3% potassium sulfate to promote fruit cell division; spraying 0.2% boric acid or 0.3% borax at full bloom helps fruit set.
3. In mid-to-late May, apply 100-250 g of urea per fruiting tree by ring broadcasting or trench application.
4. After fruit harvest, apply compound fertilizer mainly based on nitrogen fertilizer, 0.5 kg per tree.
