For standard fertilization of adult jujube trees that produce around 15 kg of fresh dates, apply 1.1 kg of urea, 0.25 kg of pentoxide, and 1.8 kg of potassium sulfate. For young saplings, it is recommended to apply 25 grams of pure nitrogen per year, along with 20 grams of phosphorus pentoxide. This balanced approach ensures healthy growth and development throughout the growing season.
Summer pruning is essential for jujube trees that have not experienced sufficient shoot growth during the flowering period or have shown low fruiting. Timely summer cuts help improve air circulation, reduce disease risk, and promote better fruit set. Focus on removing weak, crossing, or overcrowded branches to encourage a more open and productive canopy.
Pest control remains a critical task during this period. Continue to monitor and manage diseases like leaf spot. A recommended treatment includes mixing 90% mancozeb at a 3000-fold dilution with 1.8% abamectin at 3000–4000 times dilution, or 9.5% chlorfenapyr at 4000–5000 times dilution. These solutions are effective against pests such as red spider mites and cotton bollworms. Products like Bao De can also be used for additional protection. Additionally, pay close attention to jujube rust. Starting from July 10th, combine the application of fungicides like Wansheng, Fuxing, Yibao, or other azole-based pesticides to prevent rust. Apply every 7–10 days, especially within three days after rainfall, to ensure maximum protection.
If a wound or bark split in early July does not heal naturally, apply a bark sealant. The process involves carefully removing the old sealing mud, identifying new callus tissue, then applying the liquid directly to the damaged area. Afterward, cover the site with soil or plastic wrap. Make sure to loosen the plastic after one or two days to avoid overheating and potential damage to the tree's tissues. This method helps protect the tree from infections and promotes faster healing.
