Problems solved by technology

[0003] In the introduction and domestication of alpine rhododendrons, the problem of low germination rate of seed propagation was solved, but the seedlings of seed propagation grew extremely slowly. From sowing to flowering, it took as little as one year and as many as more than a year, which affected the promotion and application of alpine rhododendrons.

Embodiment 1

[0017] A method for grafting and propagating Rhododendron alpine, comprising the following steps:

[0018] (1) From March to April, select 3-year-old robust Rhododendron maxima plants as rootstocks, and use the position where the branches are evenly distributed on the tree as the grafting point. In sunny weather, select purebred Alpine Rhododendron 1-year-old robust branches that have just sprouted, and cut them off. Form a scion with 2-3 buds, and the length of the scion is 6-8 cm. After the scion is cut, apply a starch solution with ferrous chloride dissolved in the incision, seal it with a plastic wrap, and use the whole scion with The temperature is 20°C and the humidity is 90% wet towel wrapping;

[0019] (2) Before grafting, dip the bottom of the scion in a solution of naphthalene acetic acid with a concentration of 100ppm for 10 seconds. Graft by splitting and cutting. Size, insert the scion into the cut of the rootstock, align the rootstock with the phloem of the scio...

Embodiment 2

[0026] A method for grafting and propagating Rhododendron alpine, comprising the following steps:

[0027] (1) From March to April, select 4-year-old robust Rhododendron maxima plants as rootstocks, and use the position where the branches are evenly distributed on the tree as the grafting point. In sunny weather, select purebred Alpine Rhododendron 1-year-old robust branches that have just germinated, and cut them off. Form a scion with 2-3 buds, and the length of the scion is 6-8 cm. After the scion is cut, apply a starch solution with ferrous chloride dissolved in the incision, seal it with a plastic wrap, and use the whole scion with The temperature is 23°C and the humidity is 93% wet towel wrapping;

[0028] (2) Before grafting, dip the bottom of the scion in a solution of naphthalene acetic acid with a concentration of 110ppm for 12 seconds. Graft by splitting and cutting. Size, insert the scion into the cut of the rootstock, align the rootstock with the phloem of the sc...

Embodiment 3

[0035]A method for grafting and propagating Rhododendron alpine, comprising the following steps:

[0036] (1) In March-April, select 5-year-old robust Rhododendron maxima plants as rootstocks, use the evenly distributed branches on the tree as grafting points, and select 2-year-old robust branches of purebred alpine Rhododendrons that have just sprouted in fine weather, and cut them Form a scion with 2-3 buds, and the length of the scion is 6-8 cm. After the scion is cut, apply a starch solution with ferrous chloride dissolved in the incision, seal it with a plastic wrap, and use the whole scion with The temperature is 25°C and the humidity is 95% wet towel wrapping;

[0037] (2) Before grafting, dip the bottom of the scion in a solution of naphthalene acetic acid with a concentration of 120ppm for 15 seconds. Graft by splitting and cutting. Size, insert the scion into the cut of the rootstock, align the rootstock with the phloem of the scion, press the scion with the skin of...

Abstract

The invention relates to the technical field of rhododendron planting, and discloses a grafting breeding method of rhododendron hybride. With rhododendron decorum being stocks and with branches of rhododendron hybride being scions, the affinity of rhododendron decorum and rhododendron hybride is good, genetic materials can be expressed, by studying the influence of the grafting part, the graftingtime and scion treatment on the grafting survival, the technical problem that the healing performance of a scion subcutaneous forming layer is poor is solved, a grafting method is adopted, the grafting joint is prevented from ectopia, the cutting survival rate is high, the vitality is high, and the branches are good in development. Compared with a common grafting mode, the time for the scions to form the callus is shortened by 3-5 days, the time for the scions to grow new buds is shortened by 7-10 days, the scion survival rate achieves 99.9% or above, the breeding mode of quick growth, high yield and high quality of rhododendron hybride is started to promote development and utilization of rhododendron hybride, and the gardening ornamental value of rhododendron hybride is fully developed.

Description

technical field [0001] The invention belongs to the technical field of rhododendron planting, and in particular relates to a method for grafting alpine rhododendron. Background technique [0002] Alpine Rhododendron: small evergreen shrub, up to 1 meter high, densely branched, prostrate or straight. The leaves are often scattered on the top of the branches, leathery, light gray to dark gray green above, light yellowish brown to reddish brown below, petioles covered with scales. Inflorescence terminal, umbellate, with several flowers, flower bud scales shedding, calyx small, reddish or purple, corolla broadly funnel-shaped, lavender-rose to purple, rarely white, filament base covered with wool, capsule oblong egg Shape, flowering from May to July, fruiting from September to October. Born in mountains, tundra, rocky places or swampy areas. Produced in Daxing'an Mountains, Changbai Mountains and Inner Mongolia in Northeast China. There are also Canada and Alaska. The flowe...
