1. Care of Rootstock Seedlings
(1) Fertilization: Apply 20 kg of compound fertilizer per 667 square meters, mix it with water and apply evenly to ensure proper nutrient absorption by the plants. This helps promote strong root development and overall plant health.
(2) Pest and Disease Control: At the stage when new shoots appear, spray an insecticide to prevent infestations. Use 20% imidacloprid EC diluted at 800 times for effective pest control. Regular monitoring is recommended to catch any issues early.
(3) Cultivation and Weeding: Perform timely cultivation and remove weeds regularly to reduce competition for nutrients and water, and to improve air circulation around the plants.
(4) Drainage and Irrigation: Ensure proper drainage to avoid waterlogging, especially during rainy seasons. Maintain a consistent irrigation schedule to keep the soil moist but not saturated, which supports healthy growth.
2. Care of Grafted Seedlings
(1) Fertilization: Apply 20 kg of compound fertilizer per 667 square meters, mixed with water and applied thoroughly. This provides essential nutrients that support the growth of both the rootstock and the scion.
(2) Pest and Disease Management: Follow the same methods as outlined in the current month’s work calendar under the "Nursing" section. Regular inspections and timely treatments are crucial to prevent diseases and pests from affecting the graft union.
(3) Cultivation and Weeding: Continue to perform regular cultivation and weed removal to maintain a clean growing environment. This helps prevent soil compaction and ensures optimal root development.
(4) Irrigation and Drainage: Maintain a proper balance between watering and drainage. Avoid overwatering, which can lead to root rot, and ensure that excess water is drained effectively to protect the grafted plants.
By following these care practices, you can significantly improve the survival rate and growth performance of both rootstock and grafted seedlings.
