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 further described in detail by the following examples. The following examples are for explaining the present invention and the present invention is not limited to the following examples.

[0030] This embodiment includes four steps: selection and treatment of rootstock, collection and treatment of scion, grafting operation, and cultivation management:

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

[0032] Select artificially cultivated Hunan hickory seedlings as the rootstock, and use 1 to 2-year-old Hunan hickory seedlings with a thickness of 0.8cm or more, with a well-developed root system, strong growth, and no pests;

[0033] Rootstocks are treated as follows: seedlings are raised after the rootstocks have fallen leaves and before the sap flows. Select seedlings with a ground diameter of ≥0.8cm and grow strong and sturdy and dig them up with a hoe. After the seedlings are raised, the root system is moderately trimmed, and then fake plantin...

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 cultivating method for grafting pecans from Hunan pecans as rootstocks, and belongs to the technical field of grafting. Background technique [0002] Hunan Pecans ( Carya hunanensis W.C.Cheng et R.H.Chang ex Changet Lu) and pecan ( Carya cathayensis Sarg.) belong to Juglandaceae (Juglandaceae) Hickory ( Carya Nutt.) Plants. The hickory tree in Hunan is 12-20m high, 60-80cm in diameter at breast height, with straight trunk, off-white to grayish-brown bark, shallow longitudinal cracks; it likes half shade, warm, humid environment, and grows well in slightly acidic soil with rich humus; born at altitude It is produced in the valleys, creeks, and forests of 300-600m in size in Hunan, Guizhou, Guangxi and other places in China. The 4 longitudinal edges of the outer peel of Hunan hickory only extend from the top to the middle of the fruit. The core is obovate, larger, 3~3.7cm long, 2.4~2.7cm in diameter, but the shell is thick and t...
