1. Fertilization: Continue to apply a high-quality post-harvest fertilizer for bayberry trees. For weak trees, you can increase the application of urea by 0.3–0.5 kg per tree to help restore their strength and promote healthy growth.
2. Soil Coverage: After applying fertilizer, cover the soil with mulch to retain moisture and reduce weed competition. This is especially important for young trees planted in the same year, as it helps protect them from direct sunlight and improves soil conditions.
3. Pruning: Perform proper post-harvest pruning in mid-July. Remove large dead branches from the top of tall vertical branches, cross branches between two trees, and any unwanted branches on the Wang Chang tree. After cutting, apply a wound healing balm to protect the tree from disease and promote faster recovery.
4. Pest Control: 1) For aphids, spray 25% buprofezin powder diluted at 1000–1500 times, or use 40% imidacloprid at 1500 times during the second half of July. 2) For cocoon moths and leaf roller moths, manually remove them if possible, or use 20% cypermethrin EC at a suitable dilution. When spraying, focus on areas where pests are most active.
5. Growth Regulation: For over-nourished young fruit trees, control excessive shoot growth by making a circular cut around the trunk or main branches using a sickle. Apply Huawang No. 2 to promote balanced growth. Alternatively, spray the canopy with 15% paclobutrazol at 2000–2500 times dilution. Repeat the spray after 7–10 days for better results.
