Embodiment 1

[0035] This example provides the cutting propagation method of Lingbao Rhododendron. The steps include:

[0036] S1: Harvest Lingbao rhododendron twigs and soak them in disinfectant;

[0037] S2: pruning the rhododendron twigs processed in step S1;

[0038] S3: Gradient concentration soaking treatment is carried out to the Rhododendron Lingbao twigs treated in step S2 with the rooting agent;

[0039] S4: Lingbao Rhododendron twigs treated in the cutting step S3.

[0040] In step S1:

[0041] When picking twigs of Rhododendron Lingbao, choose sunny weather, and use high branch shears to pick twigs from sunny branches with a length of 30-50cm between 9:00 am and 11:00 am. The purpose of soaking the twigs of Rhododendron Lingbao with disinfectant is to prevent the incision from being infected by germs, which will cause diseases such as black stems and fail to take root. The disinfectant is a potassium permanganate solution with a volume fraction of 3-5%. The soaking time is ...

Embodiment 2

[0051] In this example, 30 Lingbao Rhododendron twigs are propagated by cuttings. The steps include:

[0052] S1: Harvest Lingbao rhododendron twigs and soak them in disinfectant;

[0053] S2: pruning the rhododendron twigs processed in step S1;

[0054] S3: Gradient concentration soaking treatment is carried out to the Rhododendron Lingbao twigs treated in step S2 with the rooting agent;

[0055] S4: Lingbao Rhododendron twigs treated in the cutting step S3.

[0056] In step S1:

[0057] When picking twigs of Rhododendron Lingbao, choose sunny weather, and use high branch shears to pick twigs from sunny branches with a length of 30-50cm between 9:00 am and 11:00 am. The purpose of soaking the twigs of Rhododendron Lingbao with disinfectant is to prevent the incision from being infected by germs, which will cause diseases such as black stems and fail to take root. The disinfectant is potassium permanganate solution with a volume fraction of 4%. The soaking time is 2min. ...

Embodiment 3

[0065] In this example, 30 rhododendron twigs of Lingbao are propagated by cuttings. The basic steps are the same as in Example 2, except that in step S3:

[0066] When using the rooting agent to soak the Rhododendron Lingbao twigs after the step S2 in gradient concentration, first use the high concentration rooting agent to soak for a short time, then use the medium concentration rooting agent to soak for a long time, and finally use the low concentration rooting agent for a long time. Soaking the twigs of Lingbao Rhododendron can effectively stimulate the rooting of the twigs and improve the life rate. The rooting agent is IBA. The temperature of gradient concentration soaking treatment is 25°C. The gradient concentration soaking treatment includes the first concentration soaking treatment, the second concentration soaking treatment and the third concentration soaking treatment carried out in sequence. The rooting agent concentration of the first concentration soaking treat...

Abstract

The embodiment of the present invention provides a cutting propagation method of Rhododendron lingbao, which saves seeds, has simple operation steps, short seedling cultivation cycle, large number of seedlings per unit area, short seedling slowing period after planting, high survival rate, and improved In order to improve the reproduction efficiency, utilize the method of the embodiment of the present invention to propagate Lingbao Rhododendron seedlings by cuttings, the rooting capacity is large, and the root system not only grows around the cut, but also grows explosive adventitious roots under the skin of the twigs, which can also be selected according to the situation. Potted cuttings and arched film shed cuttings are easy to popularize and apply.

Description

technical field [0001] The invention belongs to the technical field of plant artificial propagation, and in particular relates to a cutting propagation method of Rhododendron lingbao. Background technique [0002] Rhododendrons are mostly shrubs, and arboreal rhododendrons are very rare. Rhododendron Lingbao belongs to trees, a variety of rhododendrons, and is rarely distributed in nature. The difference between Lingbao Rhododendron and the common Henan Rhododendron is that the leaves of this variety are thin leathery, oval or obovate-elliptic in shape, 5-9 cm long, 2.5-4.5 cm wide, small flowers, and the corolla is only 2.5 cm long. cm, no dark spots, etc., the flowering period is from mid-May to mid-June. [0003] Rhododendron Lingbao grows tall and straight, some can be as high as 20 to 30 meters, with intertwined roots and vigorous branches. Lingbao Rhododendron, the oldest existing tree, is more than 1,300 years old. It has a chest circumference of about 1.45 meters, ...
