Citrus Tachibana Fine Management Techniques in June
Fertilization and Irrigation Management
-
For young trees, apply fertilizer in late June to promote shoot growth. Depending on tree age, apply urea or high-nitrogen compound fertilizer at a rate of 0.2 to 0.5 kilograms per plant, along with diluted compost or peanut bran water. Make furrows outside the drip line and cover with soil after application.
-
For fruiting trees, focus on external root fertilization. Apply phosphorus, potassium, and seaweed fertilizers every 15 days. Healthy trees may not require root fertilization, but weak trees or those with abundant fruiting should receive potassium fertilizer supplementation by the end of June, at a rate of 0.15 to 0.4 kilograms per plant, along with micronutrient supplements.
-
During dry spells, irrigate promptly and mulch the tree disc with straw or similar materials, 10-15 centimeters thick and extending 10 centimeters from the trunk, to conserve moisture, regulate temperature, and suppress weeds.
Pruning and Shaping
-
For young trees, use a thin rope to pull the main branches to a 50°-60° angle (which will revert to 45° after untying) after new shoots have matured or before they sprout. Remove suckers and long shoots promptly; for excessively long shoots, retain 8-10 short leaves.
-
For fruiting trees, continue shoot control. Trees with fewer summer shoots can be sprayed with a fungicide. For trees with more summer shoots, manual shoot control or shoot-to-shoot control measures are advisable. Remove summer shoots from fruit-bearing branches whenever possible.
Pest and Disease Control
In June, focus on controlling pests and diseases such as scale insects, rust mites, yellow spot disease, scab, and anthracnose. Recommended control measures and chemicals include:
-
Scale insects: Dimethoate, Tebufenozide
-
Rust mites: Abamectin, Triadimefon
-
Yellow spot disease: Mancozeb, Propiconazole
-
Scab: Dodine, Fenbuconazole
-
Anthracnose: Azoxystrobin, Copper Oxide
Refer to the product instructions for concentration and precautions.
These are the fine management techniques for Citrus Tachibana in June. With the unpredictable weather of heavy rain and sunshine, growers may overlook certain aspects of tree care. By following the above three points, you can lay a solid foundation for healthy and productive Citrus Tachibana trees.
