Problems solved by technology

However, the traditional hickory rootstock grafted with hickory is recognized as a relatively difficult tree species at home and abroad. Since the number of rootstock cambium is only 1-2 layers of cells, the connection process from the incision callus to the rootstock vascular bridge after grafting It takes 4 to 5 weeks, and the duration is 20 to 30 days longer than other deciduous tree species. Secondly, the age and treatment method of the rootstock material, the control of the environmental conditions after grafting, etc. will affect the survival of grafting.
In recent years, in Zhejiang, Anhui, etc., hickory grafting has been carried out using the original stock, but the survival rate of large-scale breeding is only about 80%, and the stock used for grafting hickory is limited to the original stock.

Embodiment Construction

[0029] The present invention will be described in further detail below through examples, and the following examples are explanations of the present invention and the present invention is not limited to the following examples.

[0030] The present embodiment comprises 4 steps of selection and processing of rootstock, collection and processing of scion, grafting operation, and cultivation management:

[0031] (1) Selection and treatment of rootstock:

[0032] The artificially cultivated Hunan hickory seedlings are selected as rootstocks, and the rootstocks are 1 to 2-year-old Hunan hickory seedlings, which require a thickness of more than 0.8cm, well-developed root system, strong growth, and no pests and diseases;

[0033] The treatment of the rootstock is as follows: after the rootstock leaves its leaves and before the sap flows, the seedlings are picked up, the seedlings with a ground diameter ≥ 0.8 cm and strong growth are selected, and they are dug up with a hoe. After the ...

Abstract

The invention relates to a cultivating method for grafting carya cathayensis with carya hunanensis as rootstock, and belongs to the technical field of grafting. The cultivating method includes the four steps of selecting and treating the rootstock, collecting and treating scions, grafting and managing cultivating. Through the application of the method, the grafted plant is good in grafting healing, higher in survival rate and rapider in grafted-plant growth; the carya cathayensis is wide in suitable-planting range and higher in drought resistance, flooding tolerance and sunscald resistance.

Description

technical field [0001] The invention relates to a cultivation method for grafting hickory with Hunan hickory as a stock, and belongs to the technical field of grafting. Background technique [0002] Hunan hickory nut (CaryahunanensisW.C.ChengetR.H.ChangexChanget.) and hickory nut (CaryacathayensisSarg.) are both walnut shell family (Juglandaceae) hickory (CaryaNutt.) plant. Hunan hickory tree is 12-20m high, 60-80cm diameter at breast height, straight trunk, off-white to gray-brown bark, shallow longitudinal fissures; prefers semi-shade, warm and humid environment, grows well in slightly acidic soil rich in humus; grows at altitude 300-600m valleys, streamsides and miscellaneous forests, produced in Hunan, Guizhou, Guangxi and other places in China. The four longitudinal ribs of the exocarp of Hunan hickory nut only extend from the top to the middle of the fruit. The core is obovate and relatively large, 3-3.7cm long and 2.4-2.7cm in diameter, but the shell is thick and the...
