Embodiment 1
[0016] 1) Seedling selection, in the early summer season, take one to two-year-old young shoots, cut into 30cm long cuttings, each section contains 3 nodes;
[0017] 2) Soil quality selection: choose sandy loam soil with loose soil quality. In the early stage of cutting, cut the lower end of the cutting seedlings near the joints into a slope, and make one bundle for every 40 roots. When preparing cuttings, it is strictly necessary to ensure that the cuttings do not wilt; the row spacing of the pricking plants is 5cm×10cm; after the cuttings, spray water frequently at the initial stage to keep the soil moisture at 50-60%; after the callus is produced, keep the soil moisture moist; Spray water once every 30 minutes, subject to the formation of water film on the leaves, keep moist 55%; after a large number of roots, gradually increase the light;
[0018] 3) Fertilization and sterilization: After 70% of the cutting seedlings take root, spray a 0.5% foliage fertilizer every five da...
Embodiment 2
[0021] 1) Seedling selection, in the early summer season, take one to two-year-old young shoots, cut into 30cm long cuttings, each section contains 4 nodes;
[0022] 2) Soil quality selection: choose sandy loam soil with loose soil quality. In the early stage of cutting, cut the lower end of the cutting seedlings near the nodes into a slope, and make a bundle of 40 roots. Soak the lower end of the cuttings with indole butyric acid (IBA) solution for 10 minutes, and dry the medicine. After the liquid is ready for cutting, it should be strictly guaranteed that the cuttings will not wilt; the row spacing of the holed plants is 5cm×10cm, and the water should be sprayed frequently at the initial stage after cutting to keep the soil moisture at 60%; after the callus is produced, keep the soil moisture moist; after rooting, Spray water once every 20 minutes, subject to the formation of water film on the leaves, keep moist 65%; after a large number of roots, gradually increase the ligh...
Embodiment 3
[0026] 1) Seedling selection, in the early summer season, take one to two-year-old young shoots, cut into 30cm long cuttings, each section contains 3 nodes;
[0027] 2) Soil quality selection: choose sandy loam soil with loose soil quality. In the early stage of cutting, cut the lower end of the cutting seedlings near the joints into a slope, and make one bundle for every 40 roots. Soak the base of the lower end of the cuttings with 500 mg / kg rooting powder solution for 10 minutes, and dry the liquid medicine. In preparation for cutting, it is strictly necessary to ensure that the cuttings do not wilt; after cutting, spray water frequently at the initial stage to keep the soil moisture at 60%; Form a water film as the standard, keep it moist at 65%; after a large number of roots have taken root, gradually increase the light; the row spacing of the hole-piercing plants is 5cm×10cm, insert 2 / 3 of the cuttings into the holes, water them after burying, and take root and germinate i...
