Problems solved by technology

The survival rate of seed propagation is high, but it must rely on imports, the price is relatively expensive, and the seedlings cultivated are highly variable and late in fruiting. They are generally used for afforestation or rootstock cultivation.
Grafting can effectively shorten the period of fruit bearing, but it requires a large number of rootstocks and scions, which is time-consuming and labor-intensive, and the cost is high
Cutting propagation has the advantages of convenient material collection, short seedling period, and the ability to maintain the excellent traits of the parents. However, hickory is a tree species that is difficult to propagate by cutting. There are few studies on hickory cutting propagation in my country, and there are not many reports on successful cuttings. Because hickory cuttings are not easy to root, the cutting survival rate is not high
[0004] There are many methods about the technology of inducing adventitious roots of hickory nuts. The prior art, such

Embodiment 1

[0016] A method for inducing adventitious roots of hickory nut includes the following steps:

[0017] 1) Take the annual pecan branches and cut them into 10cm-long cuttings. The cuts are flat and inclined to ensure that there are 2 full buds on each cutting. The upper cut is 2cm above the buds and there is no break. Put the cuttings into bundles and hide ; After the bottom of the slotting bed is leveled, pave 2cm thick fine stones, then pave 1cm thick straw, and evenly spread 2cm thick perlite, and evenly lay geothermal wires on the perlite in a "U" shape with a spacing of 10cm, and then lay it 8.0cm thick cutting soil, the cutting soil is a mixture of border soil, vermiculite, and turf soil with a volume ratio of 3:5:1; all the substrates used have been disinfected and sterilized; the cutting hotbed can provide a warm and moisturizing for the cuttings The growth environment speeds up the rooting of cuttings;

[0018] 2) Accurately weigh 0.2 part of indole acetic acid, 0.6 part of...

Embodiment 2

[0022] A method for inducing adventitious roots of hickory nut includes the following steps:

[0023] 1) Preparation of cuttings: Take the annual pecan branches and cut them into 15cm-long cuttings. The cut is flat and inclined to make sure that there are 3 full buds on each cutting. The upper cut is 4cm above the bud without cracking, and the cuttings are formed Bundling in shade; the rooting rate of annual cuttings is higher, and preservation in the dark is beneficial to prevent the water loss of cuttings and increase the survival rate of cuttings;

[0024] 2) Prepare cutting hotbed: After the bottom of the bed is leveled, pave 3cm thick fine stones, then 2cm thick rice straw, and evenly spread 3cm thick perlite, and lay geothermal wires evenly on the perlite in a "U" shape, spaced apart The cutting soil is 12cm thick, and then 10.0cm thick cutting soil is laid. The cutting soil is a mixed matrix of border soil, vermiculite and grass charcoal soil with a volume ratio of 4:4:3; al...

Embodiment 3

[0028] A method for inducing adventitious roots of hickory nut comprises: preparing cuttings, preparing a cutting bed, compounding a gel rooting agent, cuttings, and post-processing, which specifically includes the following steps:

[0029] Preparation of cuttings: Take the annual pecan branches and cut them into 15cm-long cuttings. The cuts are flat and inclined to ensure that there are 3 full buds on each cutting. The upper cut is 3cm above the buds without cracks, and the cuttings are bundled into shades. Tibetan: The rooting rate of annual cuttings is higher, and preservation in the dark is beneficial to prevent the water loss of cuttings and improve the survival rate of cuttings;

[0030] Prepare cutting hotbed: After the bottom of the bed is leveled, pave 3cm thick fine stones, then 2cm thick straw, and evenly spread 2cm thick perlite, and lay geothermal wires evenly on the perlite in a "U" shape with a spacing of 12cm , And then lay 10.0cm thick cutting soil, the cutting soi...

Abstract

The invention discloses a method for inducing adventitious rooting of Carya cathayensis Sarg.. The method comprises the steps of preparing cuttings, preparing a cutting hotbed, compounding a gel rooting agent, carrying out cutting and carrying out post-processing. The beneficial effects are as follows: after the cuttings are soaked in the gel rooting agent, a layer of rooting agent film is formedon the surface of the cuttings, the partial gel rooting agent film on the ground can reduce water evaporation of the cuttings and prevent the cuttings from being withered and diseased, the partial gelrooting agent film under the ground absorbs water in the cutting matrix and can keep a moist state and also slowly release the rooting agent to stimulate the rooting of the cuttings, the number of rooting, the root length and the thickness of the cuttings are increased, and thus the survival rate of the cuttings is improved; and seedlings can be provided with a warm and moist environment by setting up a thin film arch shed on a seedbed, direct sunlight is avoided, water evaporation of the seedlings is reduced, the survival rate of the cuttings is improved, and therefore, the method of the invention is a simple and efficient method for inducing adventitious the rooting of Carya cathayensis Sarg..

Description

Technical field [0001] The invention belongs to the technical field of plant rooting, and particularly relates to a method for inducing adventitious roots of hickory. technical background [0002] Hickory (Carya cathayensis Sarg.), also known as walnut tree and walnut tree. It is a deciduous tree belonging to the genus Hickory of the Juglans family. It is 10-20 meters high and has a diameter of 30-60 cm at breast height. The bark is smooth, off-white and smooth. The branchlets are thin and the new branches are densely covered with shield-shaped orange-yellow glands. Later, the glands gradually became thinner, with 1-year-old branches purplish-gray, with sparse pubescent hair on the upper end, round and sparse lenticels. The pecan fruit has been recognized by consumers due to its high nutritional value and unique taste and flavor, and has gradually become a popular high-end nut. China is one of the places of origin, suitable for sparse forests on the foothills or valleys with ri...
