Method for grafting Ilex sp. by taking Ilex dabieshanensis as stock

A technology of holly and rootstocks, which is applied in the field of holly in Dabie Mountains as a rootstock for grafting holly with colorful leaves. It can solve the problems that rootstocks are vulnerable to scale insects and other problems, and the cost of management and maintenance is high, so as to improve the survival rate of grafting, solve the shortage of resources, and simple technology Effect

AI Technical Summary

Problems solved by technology

In the existing grafting method, the scion of the new variety of Ilex coleus is usually removed from the parent body, and then grafted on rootstocks such as Chinese wolfberry. These rootstocks are vulnerable to scale insects, etc., and the maintenance cost is relatively high.
Adapting measures to local conditions, saving costs, and large-scale industrialization The method of using Dabie Mountain holly as rootstock to graft new varieties of Ilex variegata has not been reported yet.

Embodiment 1

[0029] Rootstock seedlings are cut off the part more than 8 centimeters from the ground, remove the branches below the notch, select a flat and smooth part, and from the notch downward, use the tip of the scissors to longitudinally cut the cortex into a 2 cm long and deep xylem mouth, Gently peel off the cortex at the upper end of the incision to both sides with the tip of the scissors, then keep 4 cm below the scion bud and 1 cm above the bud, and cut a 25 mm long round shield-shaped slope on the side or back of the bud, and then gently cut it with a knife. Peel off the old skin on both sides of the back side of the slope, so that it does not injure the xylem and expose the phloem, the slope of the scion faces the xylem of the stock, slowly insert it under the skin of the rootstock, and make the top of the slope of the scion show 3 mm white, and use a non-drip film Tightly wrap the interface from bottom to top with a belt, and buckle and tie the buds of the scion tightly.

Embodiment 2

[0037] Rootstock seedlings are cut off the part more than 5 centimeters from the ground, remove the branches below the notch, select a level and smooth position, and from the notch downwards, the cortex is longitudinally cut into a vertical mouth that is 1 centimeter long and deep to the xylem with the tip of the scissors. Gently peel off the upper cortex of the incision to both sides with the tip of the scissors, then keep 3.5 cm under the scion buds and 8 mm above the buds, and cut a 2 cm long round shield-shaped slope on the side or back of the buds, and gently cut them with a knife. Peel off the old skin on both sides of the back side of the slope, so that it does not injure the xylem and expose the phloem, the slope of the scion faces the xylem of the rootstock, slowly insert it under the skin of the rootstock, and make the top of the slope of the scion show 2 mm white, and use a non-drip film Wrap the interface tightly from bottom to top.

Embodiment 3

[0047] Rootstock seedlings are cut off the part more than 6.5 centimeters from the ground, remove the branches below the notch, select a level and smooth position, and from the notch downwards, use the tip of the scissors to longitudinally cut the cortex into a vertical mouth that is 1.5 centimeters deep and reaches the xylem. Gently peel off the cortex at the upper end of the cut to both sides with the tip of the scissors, then leave 3.7 cm under the scion buds and 9 mm above the buds, cut a 2.2 cm long horse-ear-shaped slope on the side or back of the buds, and then gently cut them with a knife. Peel off the old skin on both sides of the back side of the inclined plane, so that it does not injure the xylem and expose the phloem. The inclined plane of the scion faces the xylem of the rootstock, and slowly inserts it under the skin of the rootstock, so that the upper part of the inclined surface of the scion is 2.5 mm white. Use a non-drip film The belt tightly wraps the interf...

Abstract

The invention provides a method for grafting Ilex sp. by taking Ilex dabieshanensis as a stock. The method comprises the following steps: performing ingraftment scion on the Ilex dabieshanensis serving as the stock and an Ilex sp. new variety serving as a scion by means of a cut grafting method; and performing layered alignment on the Ilex dabieshanensis and the Ilex sp. to graft successfully. Through adoption of the method, the adaptability of the Ilex sp. new variety is improved, the stock is readily-available, the cost is low, the propagation coefficient is increased, the yielding capacity is increased, and scale production of the Ilex sp. new variety becomes possible.

Description

technical field [0001] The invention belongs to the technical field of seedling propagation of woody plants, and in particular relates to a method for grafting holly holly with Dabie mountain holly as a rootstock. Background technique [0002] Ilex sp. is a plant of the genus Ilex in the family Aquifoliaceae. It is a kind of colorful evergreen small trees or shrubs with bright leaves, 2-6 meters high, green leaves with golden edges, silver edges or golden hearts, etc., shiny, oval to oval, 2-4 cm long , 2-3 cm wide, green and white flowers, bright red fruit, spherical, 8 mm in diameter, flowering April-June, fruit October-December. It likes a warm, humid, and well-lit environment. It requires fertile soil and good drainage. It is suitable for sandy loam rich in organic matter. During the growing season, it is fully watered and fertilized to facilitate its growth. This kind of tree species has a spherical crown, green and colorful leaves, and many red fruits. It is a good o...
