Embodiment 1

[0051]This example was carried out in Suihua City, Heilongjiang Province from 2015 to 2016. Hardwood cuttings were carried out on the seabuckthorn variety "Deep Autumn Red". The survival rate of the first cutting was 95%, and the survival rate of the second cutting, that is, the survival rate of bud wiping and micropropagation reached 88%. , increasing the reproduction coefficient by 2 times.

[0052] to combine figure 1 , the specific operation steps are as follows:

[0053] (1) Select cuttings: pick the cuttings during the dormant period of the tree body, and in the middle and late October of autumn, select disease-free branches with a thickness of not less than 0.3cm and 1-2 years old as cuttings; Sand storage is carried out to ensure the humidity of the cuttings.

[0054] (2) Preliminary preparation:

[0055] ① Seedling tray: The specification of the seedling tray is 50 holes, the aperture is 45-50mm, the length x width x height is 545mm x 280mm x 50mm, and the number o...

Embodiment 2

[0079] This example was carried out in Heilongjiang Province from 2015 to 2016. Hardwood cuttings were carried out on the seabuckthorn variety "Deep Autumn Red". The reproduction factor is 1.5 times.

[0080] The specific operation steps are as follows:

[0081] (1) Selecting cuttings: pick the cuttings during the dormant period of the tree body, and in March, select disease-free branches with a thickness of not less than 0.3cm and 1-2 years old as cuttings; after selecting cuttings, sand the cuttings , to ensure the humidity of the cuttings.

[0082] (2) Preliminary preparation:

[0083] ① Seedling tray: The specification of the seedling tray is 50 holes, the aperture is 45-50mm, the length x width x height is 545mm x 280mm x 50mm, and the number of preparations depends on the number of cuttings;

[0084] ② Substrate: The substrate is mixed according to the mass ratio of (herbicide-free) field soil: decomposed organic fertilizer: perlite is 4:1.2:0.8;

[0085] ③Water supp...

Embodiment 3

[0103] This example was carried out in Heilongjiang Province from 2016 to 2017. Hardwood cuttings were performed on the seabuckthorn variety "Deep Autumn Red". The survival rate of the first cutting was 93%, and the survival rate of the second cutting, that is, the micropropagation of buds, reached 85%. The reproduction factor is 1.6 times.

[0104] The specific operation steps are as follows:

[0105] (1) Selecting cuttings: pick the cuttings during the dormant period of the tree body, and in late April, select disease-free branches with a thickness of not less than 0.3cm and 1-2 years old as cuttings; since the temperature reaches above 15°C, choose cuttings Finally, there is no need to sand the cuttings, and they can be cut directly.

[0106] (2) Preliminary preparation:

[0107] ① Seedling tray: The specification of the seedling tray is 50 holes, the aperture is 45-50mm, the length x width x height is 545mm x 280mm x 50mm, and the number of preparations depends on the nu...

Abstract

The invention provides a cuttage seedling method for a hippophae rhamnoides hard branch. The cuttage seedling method for the hippophae rhamnoides hard branch comprises the steps that (1) a cutting isselected; (2) shearing treatment is carried out on the cutting; (3) a cutting slip is soaked; (4) the soaked cutting slip is inserted into a matrix; (5) watering is carried out every day after cuttage; (6) after cuttage is carried out for 40-50 days, a nursery stock is transplanted; after transplanting is carried out for 7-10 days, bud picking is carried out, and only one bud tip remains; and whenthe height of the nursery stock is 40-60 centimeters, the nursery stock can be transplanted from a nursery garden to be used for afforestation; (7) picked bud micropropagation is carried out, wherein5-7 centimeters of bud tips are selected in the picked bud tips, after step (3)-(5) are repeated, transplanting is carried out after cuttage for 40-50 days, the nursery stock lives through the winteron the nursery garden, in the next year, after the height of the nursery stock reaches 70 centimeters or above, the nursery stock can be transplanted from the nursery garden to be used for afforestation. The cuttage seedling method for the hippophae rhamnoides hard branch has the advantages that during hippophae rhamnoides hard branch cuttage seedling, cuttage seedling is carried out on the picked bud tips again, the cuttage coefficient is improved by 1-2 times, the survival rate is high, the primary cuttage survival rate is 90% or above, and the secondary cuttage survival rate can reach 80%or above.

Description

technical field [0001] The invention belongs to the technical field of seedling breeding, and in particular relates to a seabuckthorn hard branch cutting seedling raising method. Background technique [0002] Seabuckthorn (Hippophae L.) is a deciduous shrub or small tree of the genus Hippophae L. in the genus Hippophae. It is a precious economic forest tree species containing the most natural vitamins in the world. A treasure trove of natural vitamins. Seabuckthorn has high nutritional value, ecological value and economic value, especially plays an important role in the construction of "Three North" shelterbelts. It has become an economic tree species integrating ecological, economic and social benefits, and has been widely valued by countries all over the world. In order to make seabuckthorn more effective, the cultivation of seabuckthorn has gradually changed from a completely ecological type to an ecological and economical type. Seabuckthorn cultivation of improved varie...
