Rootstock preparation. Collect fully ripe camellia fruit, air dry in shade, filter healthy large seeds and disinfect with potassium permanganate. Spread a clean sand layer of 15 cm thick on a well-drained flat surface. Spread evenly a layer of seeds, cover a 10 cm thick river sand, and then cover the film and the shade net. At the end of February or early March, the film and shade net on the sand bed were uncovered, and the water was sprayed through the sand bed to germinate, and it was ready for grafting at the end of April. Nursery preparation. Choose a rice paddy field that is convenient for transportation, drainage and irrigation. Deep in the early winter. In mid-March of that year, 2000 kg of organic fertilizer and 100 kg of superphosphate were applied per acre, and the soil was disinfected to form a seed bed with a width of 1 to 1.2 meters, covering 5 centimeters of yellow earth. Open drainage ditch, set up shade shed, shade 1.8 to 2 meters high, 70% to 80% shading. Grafting preparation. Prepare grafting supplies such as thin aluminum sheets, single-sided blades, towels, pots, planks, and labels. The semi-lignified and healthy spring shoots were collected on the parent tree of the Camellia oleifera seedlings that passed the review (recognition), and were followed by picking. Long-distance transport requires air-conditioned vehicles, and pay attention to moisturizing, and save it on a sand bed in the shade. grafting. 1, from the anvil. Gently excavate the rootstock and wash the sand. 2, cutting ear. In the lower part of the bud 0.5 cm under the knife, cut into a wedge-shaped, and then cut off at 0.5 cm above the bud, the scion will be cut in a pot filled with water for use. 3, anvil. About 3 cm in the rootstock germ cut off, cut a knife in alignment with the axis, about 1.0 to 1.2 cm deep, rootstock embryo root retention 6 to 8 cm. 4, inserting and dressing. Insert the scion into the cut of the rootstock, align the layers, lightly pinch at the interface with a thin aluminum skin, hang the label, place it in a cool place, and cover it with a damp cloth. Planting. The row spacing is 3 cm and 15 cm, and it is disinfected with an agent such as chlorothalonil and soaked with water. Set up the bamboo bow and cover the film. Nursery management. About 40 days after planting, the buds that grew from the rootstock were cut off in time. Remove weeds in time. Sprinkle irrigation in time, once every time the film is sprayed. When the seedlings grow to 3 to 5 centimeters, spray water can be combined with 0.2% nitrogen fertilizer water. About one and a half months after grafting, the two ends of the film cover will be uncovered and the plastic film cover will be removed sooner or later in cloudy or sunny days. Demolition of the shed after mid-September. Camellia light substrate container nursery. Ordinary seedlings generally use 10 cm 12 cm plastic cups, light substrate seedlings use 6.5 cm in diameter non-woven mesh bags. The nursery substrate requires loose, air-permeable, non-stiffening, mainly peat, sawdust, rice husk and so on. In mid-to late October, highly suitable seedlings were transplanted into a nutrition cup. The first step is to take the seedlings, gently pinch the sprouts and the seedlings to slowly extract upwards, remove them, put them in the basket, and cover them with a wet towel. The second step is to plant the seedlings and gently raise the seedlings by hand to stretch the roots and fully compact the soil. Each container is planted with a seedling, which is then watered immediately after planting. Transplanting should be done in the rainy or sunny days.
