Description
Technical Field
The invention relates to the field of plant propagation, in particular to a grafting propagation method of witch hazel.
Background
In the technical field of plant propagation, grafting is one of artificial nutrition propagation methods of plants. That is, a branch or bud of one plant is grafted onto a stem or root of another plant, and the two parts joined together are grown into a complete plant. During grafting, the scion and the cambium of the stock are tightly combined to ensure the survival of the scion. The grafted branch or bud, called scion, and the grafted plant body, called rootstock or table wood. The scion grafted to the top of the plant and the stock grafted to the root of the plant.
The Hamamelidaceae plant is woody, such as maple, mushroom, Calla, brazil, cupra, Crassulaceae, and Pterocarya, and can be used for building and furniture. For pharmaceutical use, there are genera of sweetgum, mushroom, semiliquidambar, hamamelis, rhinobyon, and petaloid. The resin of the genus Liquidambar and the genus Mylabris can also be used as perfume and perfume-fixing material. In addition, most of the genera have ornamental value, especially the Hedsura and Calophyllum have the most ornamental value. Insect gall on leaves of some species of the genus Hemidge can be used as Galla chinensis.
Hamamelis virginiana, Hamamelidaceae (scientific name: Hamamelidaceae R.Br.), Hamamelidaceae, deciduous shrub or small tree, yellow flower, flowering in 2-3 months, is an excellent garden ornamental plant in early spring.
At present, the propagation of witch hazel mainly depends on seed propagation, but some varieties with ornamental characters need asexual propagation such as cuttage, grafting or tissue culture and the like.
At present, the stock of a hamamelis seedling nursery is less, but the stock of the anopheles sinensis, the myrica rubra leaf anopheles and the round-head anopheles of different families is more, and the commodity value is low. The method for grafting the witch hazel by using the mosquito nut trees, the waxberry leaf mosquito nut trees and the round-head mosquito nut trees as the rootstocks can simultaneously solve the problems of insufficient rootstocks for grafting and propagating the witch hazel and excessive nursery stocks of the mosquito nut trees, the waxberry leaf mosquito nut trees and the round-head mosquito nut trees. Meanwhile, the respective drought resistance, barren resistance and water-moisture resistance of the three stocks can be effectively utilized to improve the planting adaptability of the mosquito-repellent incense.
In the art, generally, graft propagation scions and rootstocks need to have high affinity; generally, the grafting compatibility is highest among the same species, and is inferior among different species within the same genus, and the grafting compatibility is poor among different genera. The method relates to the effective grafting of witch hazel by taking the mosquito-tree, the waxberry leaf mosquito-tree and the round-head mosquito-tree as stocks, has no relevant report, explores the feasibility and the effect of relevant methods, and has practical value in technology.

(2) Treating the rootstock: the stock is cut off or sawed off at the grafting part. The position of the cut is important so that the remaining stump surface is smooth and has a straight texture, at least within 6cm above and below it, without scarring. After the grafting part is selected and cut off, vertically cutting the stock bark by a grafting knife to a length of about 4 cm and reach the xylem, and slightly prying off the bark on one side.
(3) Bonding: the thin side of the scion is gently inserted into the pried rootstock skin inwards, so that the thick side of the scion cutting surface is outside, and the thin side is inside.
(4) Binding: the joint part is tightly bound by a plastic strip, and then a plastic bag is sleeved for moisture preservation.
(5) And (4) management after connection: after grafting, a shade shed is built in time to shade, so that the phenomenon that the scion wilts due to high temperature in the plastic bag caused by direct sunlight is avoided. And after the scion and the rootstock are healed and sprout, gradually removing the moisture-preserving plastic bag.
