Embodiment 1

[0058] Three species of Pagoda sylvestris, red beans, and palm trees with a ground diameter of more than 1 cm were selected as rootstocks. The method of the present invention was used for grafting in early April. A randomized block experiment design was adopted, and each rootstock species was repeated 3 Repeatedly grafted 15 plants each time, a total of 45 plants. After grafting, the grafted seedlings are placed in a greenhouse, and the temperature is 20-30°C and the humidity is about 50%. The new shoots on the rootstock are wiped off in time, and the surviving plants are cut off the rootstock 1cm above the scion. Check for survival after 20 days, and check for germination after 25 days.

Embodiment 2

[0064] Due to the scarcity of provenances of palm tree, the red beans with a diameter of more than 1cm were selected as the rootstock. The grafting cuttings were treated with three different methods for 0d, 5d, 10d, and 25d, and the method of the present invention was used in early April For grafting, a randomized block experiment design was adopted, with each group of grafting repeated 3 times, and each repeated grafting 15 plants, a total of 45 plants. The three methods are: a. Wrap it in a clean wet towel and put it in a plastic bag to empty the air for shade; b. Keep it at 4°C and keep it cool; c. Keep it at room temperature for moisture. After grafting, the grafted seedlings are placed in a greenhouse, kept at a temperature of 20-30°C and a humidity of about 50%, and checked to survive about 20 days.

Embodiment 3

[0070] Due to the scarcity of provenances of palm tree, the red beans with a diameter of more than 1cm were selected as the rootstock, and cut splicing, split splicing, shield budding, H-shaped peeling budding, and grafting of the present invention were used in early April. Grafting adopts a randomized block experiment design, each grafting method is repeated 3 times, and each repeat grafting 15 plants, a total of 45 plants. After grafting, the grafted seedlings are placed in a greenhouse, and the temperature is 20-30°C and the humidity is about 50%. The new shoots on the rootstock are wiped off in time, and the surviving plants are cut off the rootstock 1cm above the scion. Check for survival after 20 days, and check for germination after 25 days.

Abstract

The invention discloses an ormosia henryi grafting method. Ormosia henryi or western Hubei ormosia hosiei is used as stocks, current-year branches of ormosia henryi are used as scions, and grafting isperformed front the end of March to the end of April. The ormosia henryi grafting method has the advantages that grafting is successively applied to perform vegetative propagation of ormosia henryi,the survival rate is 90% or above, the germination rate is 80% or above, the current-year growth height can reach 0.8 m or above after germination, and the problem of vegetative ormosia henryi propagation which cannot be achieved through grafting is solved.

Description

Technical field: [0001] The invention belongs to the technical field of asexual reproduction of palm trees, and specifically relates to an efficient grafting method of palm trees. Background technique: [0002] Ormosia henryi Prain (Ormosia henryi Prain) is a plant belonging to the genus Papilionaceae. Its bark is gray-green, smooth, with light cracks, odd-pinnate compound leaves, dark green on the top, smooth and hairless, and densely yellow-brown on the bottom and petioles. Fluff, mainly produced in Anhui, Zhejiang, Jiangxi, Hunan, Hubei, Guangdong, Sichuan, Guizhou, Yunnan (southeast), is a national secondary key protected wild plant. Its wood is excellent, and it is one of the important and precious commodity timber species in our country, and its beautiful tree shape has great garden ornamental value, and it can also be used as garden and street greening tree species. In recent years, due to artificial over-logging and the destruction of the ecological environment, wild pal...
