Embodiment 1

[0045] In the first ten days of June, 2011, 60 3-year-old slate trees with strong growth and no diseases and insect pests were selected as rootstocks. The scion was selected from the strong spring shoots of two camellia varieties, Fenshibashishi and Samsana, and the scion was grafted with broken stock. 30 plants of each variety were grafted.

[0046] Rootstock treatment: The height of the main stem is 60cm, 70cm, and 80cm from the pot soil. Use a blade to flatten the interface, remove all the other branches from the base, and immediately apply a layer of Vaseline to the interface and wound to prevent bacterial infection.

[0047] Collection and processing of scions: collect in the early morning, bundle the harvested branches into small bundles according to varieties, dip the base in wet, avoid wind and sun, so as not to lose water and dry up. Before grafting, cut the branch into small sections of 3-4 cm according to 1 leaf and 1 bud, cut the joint on the side of the bud, and s...

Embodiment 2

[0051] In the first ten days of September 2011, 60 4-year-old slate trees with strong growth and no pests and diseases were selected as rootstocks, and strong spring shoots and summer shoots of the Dahong peony variety were selected as scions, and grafted by breaking the rootstock.

[0052] Rootstock treatment: the height of the main stem is cut to 1.0m, and 2 anvil branches are left. Prevent bacterial infection.

[0053] Collection and processing of scions: collect in the early morning, bundle the harvested branches into small bundles, moisten the base, avoid wind and sun, so as not to lose water and dry up. Before grafting, cut the branch into small sections of 3-4 cm according to 1 leaf and 1 bud, cut the joint on the side of the bud, and see the xylem slightly, and the length of the cut surface is 1.0-1.5 cm. , in the shape of a horse ear; then cut off 1 / 2 of the leaves, put the treated scion in a pot filled with clear water for 25 minutes, and then take it out for grafti...

Embodiment 3

[0057] In September 2012, 60 5-year-old slate trees that grew robustly and were free of diseases and insect pests were selected as rootstocks, and robust spring shoots of the sassafras variety were selected as scions, and grafted by cutting off the rootstock.

[0058] Rootstock treatment: The height of the main trunk is divided into 1.0m and 1.4m. The position of the broken anvil is 25cm from the base of the branch. Three kinds, use a blade to flatten the interface, and apply a layer of Vaseline to the wound after cutting off the remaining side branches to prevent bacterial infection.

[0059] Collection and processing of scions: collect in the early morning, bundle the harvested branches into small bundles, moisten the base, avoid wind and sun, so as not to lose water and dry up. Before grafting, cut the branch into small sections of 3-4 cm according to 1 leaf and 1 bud, cut the joint on the side of the bud, and see the xylem slightly, and the length of the cut surface is 1.0...

Abstract

The invention discloses a cultivation method of grafted camellia japonica using pyrenaria spectabilis as rootstocks. According to the method, 3 to 5 years old pyrenaria spectabilis is selected as the rootstocks, current year spring shoots or summer shoots of mother plants of excellent varieties of fenchangocai, bright red peony or camellia sasanqua are used as scions; the grafting of the camellia japonica is realized by using a broken anvil lift connection method, after grafting, the big seedlings of the camellia japonica are cultivated by the measures of water control, moisture holding, hardening seedling, cultivation promotion and the like, and the grafting survival rate can be more than 90 percent. According to the invention, the ornamental characteristics of the two plants are combined, and grafted trees can be taller and more beautiful in shapes, higher adaptability is realized, the growth can be faster after the grafting, the survival rate is higher, and the large-scale and rapid propagation of the big seedlings of the camellia japonica can be realized.

Description

technical field [0001] The invention belongs to the technical field of asexual rapid propagation of plants, in particular to a cultivation method for grafting camellias with slate wood as stock. Background technique [0002] Pyrenaria spectabilis (Charp.) C.Y.Wu&S.X.Yang and Camellia japonica L. belong to the Theaceae family. The former is an evergreen tree belonging to Pyrenaria spectabilis, one of the main native tree species in Guangxi , the latter is an evergreen shrub or small tree of the genus Camellia, a famous flower, both of which are excellent ornamental tree species with great development prospects. 5-9m tall, with straight trunk and gray-brown bark; it likes semi-shade, warm and humid environment, can withstand low temperature and frost around minus 6°C, and grows well in acidic soil rich in humus; sowing and breeding, born in In valleys, streamsides, and miscellaneous forests at an altitude of about 500m, it is produced in Yunnan, Sichuan, Guangxi, Hunan, Guang...
