Cultivation method for big and strong oil-tea camellia grafting seedlings

A cultivation method for big and strong oil-tea camellia grafting seedlings includes steps of good-quality and high-yield spike seedling grafting, planting, greenhouse cultivation and container nutrition bag seeding thin planting transplanting, and large farmland cultivation. The cultivation method is characterized in that the oil-tea camellia grafting seedlings are cultivated in a greenhouse with container nutrition bags for 5-6 months; the grafting seedlings are transferred to a large nursery farmland for uniform thin planting together with the container nutrition bags wrapped at roots, capacity for each mu is about 40 thousand grafting seedlings, and the grafting seedlings are cultivated for no less than 12 months and then are carried out of the large nursery farmland for forestation together with the container bags degraded incompletely. The cultivation method integrates advantages of bare-rooted seedling cultivation and container seedling cultivation, and solves the problems that for many years, oil-tea camellia bare-rooted seedling forestation is low in survival rate, and container seedlings higher in survival rate are not strong and grow slowly after getting out of the large nursery farmland.
