A detailed explanation of camellia grafting technology teaches you grafting

Many novice flower friends want to know how camellias are grafted. Gu Zhujun is here to sort out the detailed diagrams of camellias grafting, so that you can make a reference when grafting camellias.

The common rootstock of grafted camellia is Camellia oleifera, because Camellia oleifera is a small evergreen tree of Theaceae and Camellia is both Theaceae, and the survival rate is very high after grafting.

I. preparation before grafting

1. Suitable time for grafting: grafting can be carried out in spring, early summer and winter, especially in Meiyu season from May to June.

2. The selection method of scion: on the mother tree of the selected ornamental camellia variety, the annual branches with diameter 0.2~0.5cm Lignification or semi-Lignification with no diseases and insect pests, strong growth and full bud eyes were cut as the best scion. Keep the ear branches in handfuls according to the variety, and pay attention to moisturizing the base (such as wrapping wet newspapers).

3. The combination method of rootstock: the scion of the same rootstock must be cut from the mother tree with similar flowering time and similar appearance, so as to ensure the balance of the overall growth of the crown after grafting. A Camellia oleifera rootstock can be grafted on a variety of camellia scions to form a branch, a colorful crown, excellent ornamental.

4. The treatment method of rootstock: in the winter of last year, 3 to 5 evenly distributed main branches of Camellia oleifera were selected for cutting to promote adventitious branches, and 3 to 5 adventitious branches were carefully preserved for each branch, and then grafted after semi-Lignification of adventitious branches from June to July, which is also known as green branch grafting or tender branch grafting. If there is no such method to keep branches, choose 3 to 5 main branches with a diameter of 2 to 5 cm evenly distributed on Camellia oleifera as grafting branches. After cutting the grafted branch with a hand saw, the saw mouth is roughened and flattened with a special grafting knife and then grafted. Thicker branches can be grafted with several more scions along the periphery.

2. Grafting tools and operating steps

1. Grafting tools and auxiliary materials: need to prepare packing rope, plastic film strip, white plastic bag, splice knife, pruning shears, handsaw and so on.

2. The specific operation steps of splicing:

1) cut the scion into 5-6 cm segments, with 2-3 lateral buds in each section. In order to reduce evaporation, cut off half of the leaves.

2) cut a long slope at 1 cm below the scion, about 2 to 3 cm long, and a short face on the opposite side of the long side, less than 1 cm in length.

3) cut the section of the rootstock flat, cut down the xylem edge of the section of the rootstock, the length and width of the cut of the rootstock correspond to the length and width of the scion, then insert the length of the scion obliquely toward the rootstock, and align the cambium on one side, and wrap the cortex of the incision of the rootstock around the scion.

4) if the rootstock is thick, several scions can be grafted along the periphery, and then tied together. Bind with a plastic film strip about 1 cm wide (there should be a certain degree of elasticity) to be bound, and the film strip must be tightened when binding.

5) the grafted rootstocks and scions were covered with moisturizing film to prevent the loss of water transpiration from causing the scion to dry up.

III. Management after grafting

1) about one month after grafting, remove the moisturizing film, and remove the banding and shading paper in about two months.

2) the rootstock above the grafting position can be cut off in about three months, and then cut off the vegetative branches of the rootstock, the auxiliary branches on the rootstock and the sprouting of the rootstock for three times. One kilogram of high quality organic fertilizer such as cake fertilizer is applied to each plant in winter, and calcium superphosphate, potassium dihydrogen phosphate and urea are applied in spring and summer.

3) foliar fertilization was carried out during flower bud differentiation and flower bud expansion, and the fertilizer concentration should be about 0.3%. Spring, summer and autumn is the growing season of tea trees, which requires a lot of water, so dry watering should be seen. In winter, tea trees enter the dormant period and keep the soil moist.

4) 1000 times of poisonous filament should be sprayed to control shell insects, once every 10 days, for 3 times. Control longicorn beetles and tea stalks eat tea stalks and kill them with cotton dipped in dichlorvos emulsion twice as much as cotton. Tea twig and leaf pests can be sprayed with 1500 times poisonous silk.
