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...
