In addition, the back of the scion is also cut into an oblique angle of about 45 degrees, leaving a notch as a spare, and then using the new shoots of the bride who were cut that year as the grafting rootstock, so that the grafting can be carried out.

2. Planting seedlings by inserting bed

You can use a wooden box or direct land as a cutting bed, fill it with 15-20 cm of clean river sand, or use 70% brick powder plus 30% charcoal powder as a substrate. After the inserting bed is ready, the 30cm long dragon fruit branches are cut and placed in a cool place to dry naturally. The most suitable cutting time after 7-10 days of wound healing can reduce wound infection and decay, and the germination rate of long roots can reach more than 95%.
