Embodiment 1

[0043] Rhododendron scion grafting

[0044] Implementation time is March

[0045] ⑴Preparation of sunshade greenhouse, cutting seedbed and cutting substrate

[0046] Build sunshade sheds and install sunshade nets on the sunshade sheds, with a shading rate of about 80%;

[0047] Level the seedbed with a width of 100cm and a length of 20m. Lay a 6cm-thick cutting substrate, insert a small shed skeleton at a distance of 60cm, and prepare a 2m-width and 3-silk film for use; leave a working channel with a distance of 30cm between the cutting seedbeds;

[0048] The cutting substrate is finely divided acidic and impurity-free Hongshan loam, the substrate is laid flat, and the cuttings are watered thoroughly before cutting;

[0049] ⑵ Preparation of scion and rootstock

[0050] Select the healthy-growing rhododendron variety "Double Happiness" as the scion. After cutting the scion, place it in a cool place immediately, and spray water in time to keep it fresh for later use;

Embodiment 2

[0069] Camellia scion

[0070] Implementation time in May

[0071] Sunshade greenhouse, cutting seedbed are prepared with embodiment 1.

[0072] The cutting substrate is peat, the substrate is laid flat, and the cuttings are watered thoroughly before cutting.

[0073] The healthy-growing camellia variety "Walina Shen" was selected as the scion, and the robust "Hongluzhen" was selected as the rootstock cutting.

[0074] The preparation and pretreatment method of scion and stock cuttings are with embodiment 1.

[0075] Grafting method: use the split grafting method, put the "Hongluzhen" rootstock cuttings flat and close to the backing board, cut a 0.8cm long slit at the cutting edge of the rootstock cuttings; cut the "Walina deep" scion with a length of 2 ~3cm, keep 1 / 3-1 / 2 leaves in crosscut, leave 1-2 buds, use a blade to cut 1cm long and double-sided wedge shape with sharp top at about 1cm below the lower leaves, cut the cut scion Align the opening of the cuttings of "Hon...

Embodiment 3

[0078] Osmanthus spike

[0079] Implementation time is October.

[0080] Facilities and cutting seedbed are prepared with embodiment 1.

[0081] The cutting substrate is acidic and impurity-free red loam.

[0082] The healthy osmanthus cultivar "Fo Ding Gui" was selected as the scion, and the robust "Da Zhu Sha" was selected as the rootstock cutting.

[0083] The preparation and pretreatment method of scion and stock cuttings are with embodiment 1.

[0084] Grafting method: use the split grafting method, put the rootstock cuttings of "Big Cinnabar" flat and close to the backing board, cut a 1 cm long slit at the cutting edge of the root stock cuttings; Cut 1 / 3 of the leaf crosswise and keep 1-2 buds. Use a blade to cut a 1cm long, double-sided wedge shape with a sharp top at about 1cm below the lower leaf. Align the cut scion with the rootstock cuttings There is a gap, and at least one side of the cambium is required to be aligned. Insert it gently to make the two fit tigh...

Abstract

The invention relates to a seedling scion grafting method, which comprises the following steps of (1) sun-shading greenhouse, cutting seedling bed and cutting substrate preparation; (2) scion and stock preparation: new tips of a well-bred parent tree under the healthy growth condition are selected as scions, new tips of a well-bred parent tree under the strong growth condition are selected as stocks, the length of the stocks is about 2 to 10cm, 1 to 2 sections of leaves are left, and the left leaves are positioned in positions being 1 to 2cm below an upper shearing opening and positions being 1 to 4cm above a lower shearing opening; (3) stock pretreatment; (4) grafting: a cleft grafting method is adopted, the stock is flatly placed to be tightly adhered to a base plate, and a split opening with the length being 0.5 to 1cm is longitudinally cut in the position of the upper shearing opening, the scions with the length being 2 to 3cm is sheared, 1 to 2 buds are remained, a two-sided wedge shape with the sharp top end and the length being 0.8 to 1.2cm is cut in a position being 1cm below a scion leaf, the cut scions are aligned with the split opening of the stock, in addition, at least one side is required to form layer aligning, the cut scions are slightly inserted so that the cut scions and the stock are tightly pasted, the middle position of an aluminum sheet covers a grafting opening, and the aluminum sheet is tightly pinched and folded back so that the fixation is realized; (5) cottage; and (6) daily management.

Description

technical field [0001] The invention relates to seedling propagation technology, in particular to a seedling grafting method. Background technique [0002] Grafting is one of the widely used methods of artificial vegetative propagation of plants, that is, to graft the branch or bud (scion) of one plant to the stem or root of another plant (rootstock), so that the two parts connected together grow into a complete plant. The characteristics of grafted seedlings: the underground part of the grafted seedlings is the root system developed by the rootstock, which has the characteristics of the growth and development of the root system of the rootstock. The growth of the scion can be affected by the method of selecting the rootstock, and the adaptability of the grafted seedlings to the environment can also be enhanced. Choose different types of rootstocks such as arborization or dwarfing to control the size of the tree; the aboveground part of the grafted seedlings is developed fr...
