Embodiment 1
[0025] A kind of Siberian apricot tree cutting seedling raising method:
[0026] (1) Select the Siberia apricot tree that grows robustly and has no damage by diseases and insect pests. The 1-year-old spring semi-lignified branches are used as cuttings; the cuttings are made into a stem section with a length of 10 cm and 3 leaves. The cuts at both ends of the stem section are smooth and the lower end is inclined;
[0027] (2) Immerse the lower 1 / 3 of the stem segment in the exogenous hormone solution of IBA 600mg / L + salicylic acid 400mg / L for 60s;
[0028] (3) Mix peat, mountain base soil and river sand in a volume ratio of 2:4:2 as the cutting substrate, pour water thoroughly, and insert the soaked cuttings into the substrate with the inclined surface of the lower end of the cuttings facing down, and the insertion depth is 1 / 2 of the length of the cuttings. 1 / 3;
[0029] (4) Maintain cutting environment temperature at 26°C and air humidity at 85%;
[0030] (5) The leeward, ...

[0032] A kind of Siberian apricot tree cutting seedling raising method:
[0033] (1) select the semi-lignified branches of Siberia apricot tree that grows vigorously and have no damage by diseases and insect pests in spring as cuttings; the cuttings are made into a stem section with 8 cm in length and 2 leaves, and the cuts at both ends of the stem section are smooth, and the lower end is inclined;
[0034] (2) Immerse the lower 1 / 3 of the stem segment in an exogenous hormone solution of 400 mg / L IBA+600 mg / L salicylic acid for 75 seconds;
[0035] (3) Mix peat, mountain base soil and river sand in a volume ratio of 1:3:1 as the cutting substrate, pour water thoroughly, insert the soaked cuttings into the substrate with the inclined surface of the lower end of the cuttings facing down, and insert the cuttings to a depth of 1 / 2 of the length of the cuttings. 1 / 3;
[0036] (4) Maintain cutting environment temperature at 30°C and air humidity at 80%;
[0037] (5) Sandy loam or ...
Embodiment 3
[0039] A kind of Siberian apricot tree cutting seedling raising method:
[0040] (1) Select the 1-year-old spring lignified branch of Siberia apricot tree that grows robustly and has no damage by diseases and insect pests as cuttings; the cuttings are made into a stem section with 12 cm in length and 3 leaves, the two ends of the stem section are cut smoothly, and the lower end is inclined;
[0041] (2) Immerse the lower 1 / 3 of the stem segment in the exogenous hormone solution of IBA 800mg / L + salicylic acid 200mg / L for 45s;
[0042](3) Mix peat, mountain base soil and river sand in a volume ratio of 3:5:3 as the cutting substrate, insert the soaked cuttings into the substrate at an angle, with the lower slope of the cuttings facing down, and the insertion depth is 1 / 4 of the length of the cuttings ;
[0043] (4) Maintain cutting environment temperature at 22°C and air humidity at 90%;
[0044] (5) Sandy loam or loamy plots with leeward, gentle, deep and fertile soil and go...
