NOVELTY - Tea-oil tree grafting cutting seedling cultivating method involves preparing a lightweight matrix, selecting stock and scion, followed by soaking the graft seedling in thiophanate wettable powder liquid, and cuttage rooting accelerant comprising indole-3-butyric acid. The seedling is inserted vertically into the matrix and watered to enhance rooting, and to maintain foliage to be moisture, followed by carrying out nursery stock management and protection by spraying fungicide or insecticide 2 days after transplantation, fertilizing compound fertilizer, and hardening the seedling.    USE - Method for cultivating tea tree oil grafting cutting seedling.    ADVANTAGE - The method enables cultivating tea tree oil grafting cutting seedling with high yield and high survival rate, in simple, cost-effective and eco-friendly manner.    DETAILED DESCRIPTION - Tea tree oil grafting cutting seedling cultivating method involves preparing lightweight matrix, selecting stock and scion, taking seed after germination to 2.5-4 cm as graft, truncating 1.8-2.3 cm at top of the anvil shoots petiole and 1-1.2 width of central longitudinal section, inserting the scion, edge-aligning and tightly tying with aluminum sheet, followed by soaking the graft seedling in 75% thiophanate wettable powder liquid for 5-10 minutes, in 500-800 ppm cuttage rooting accelerant comprising indole-3-butyric acid. The seedling is inserted vertically into the matrix to 2.5-4 cm and watered to enhance rooting, and to maintain foliage to be moisture, followed by carrying out nursery stock management and protection by spraying fungicide or insecticide 2 days after transplantation, once in every 5-8 days, fertilizing 1-5% compound fertilizer once in every 7 days, watering, shading, controlling the matrix to be wet, straightening seedling leaf, improving watering and fertilizing in the late growth stage, light management, and promoting seedling growth, and hardening the seedling according to the height of the seedling, when the seedlings with height of less than 15 cm is grown, controlling watering and fertilizing to the seedling, and promoting growing roots till the seedling is grown to height of more than 15 cm.
