Embodiment 1
[0015] In spring, summer and autumn, when "Wanchu No. 1" is transplanted into live seedlings and grows to 50cm, cut the upper 30cm long branches, and then cut them to about 5cm long as cuttings, and the lower cut is smooth and inclined at 45°. The upper incision is smooth and flat, about 1cm away from the bud, leaving 1 leaf at the top of the cuttings, cutting off 2 / 3 of the remaining leaves, and keeping 1 / 3; dip the base of the cut cuttings in the prepared root-stimulating agent for 8 seconds. (The root promoting agent uses indole butyric acid (IBA) 200mg, pyridoxine hydrochloride (VB 6 )3mg and sodium molybdate (Na 2 MoO 4 2H 2 O) 0.5mg and 1kg of water are prepared to make a mixed solution). The cuttings cuttages treated with the above-mentioned root-promoting agent are placed in a plug tray equipped with a substrate, and the substrate is prepared by mixing perlite and peat in a ratio of 5:2, and using 3% ferrous sulfate or 0.1% potassium permanganate aqueous solution S...
Embodiment 2
[0017] In spring, summer, and autumn, when the live seedlings transplanted by tissue culture of "Yuchu No. 1" grow to 80cm, cut the upper 45cm long branches, and then cut them to about 15cm long as cuttings. The lower cut is smooth and inclined at 45°. The upper incision is smooth and flat, about 1cm away from the buds, leaving 1 leaf on the top of the cuttings, cutting off 2 / 3 of the remaining leaves, and keeping 1 / 3; dip the base of the cut cuttings in the prepared root-stimulating agent for 5 seconds. (The root promoting agent uses indole butyric acid (IBA) 500mg, pyridoxine hydrochloride (VB 6 ) 8mg and sodium molybdate (Na 2 MoO 4 2H 2 O) Add 1.0 mg of water to 1 kg to form a mixed solution). The cuttings cuttings treated with the above-mentioned root-promoting agent are placed in a plug tray equipped with a substrate, and the substrate is prepared by mixing perlite and peat in a ratio of 5:5, and using 3% ferrous sulfate or 0.1% potassium permanganate aqueous solution...
