The temperature of 10 ~ 30 ℃ is the best in spring and autumn. If the temperature is too high, the scion incision is easy to dry and rot; if the temperature is too low, the incision is difficult to heal, and the survival rate is low. The best grafting time is from Qingming to Guyu, from cold dew to early winter.
Crab claw orchid grafts rootstock, may choose cactus, the quantity Tianzhu and so on.
Cut the long and strong branches from the mother plant, which are more than 10 cm long, and put them in the sun for 3-4 days. After the cut becomes dry, insert them into the soil to speed up the germination, and then put them into the basin as grafting materials.
Select a green and healthy Christmas Cactus without diseases and insect pests, and cut the top stem node as scion.
Use a knife to cut 1 /3 of the lower end of the stem node to expose the white xylem, and finally cut the bottom into a wedge. When cutting with a knife to be decisive, do not repeat cutting.
At the top of the rootstock, cut a 2 cm slot lengthwise the same width as the scion.
Cut the lower end of the stem node into a 1.5cm duck tongue shaped cutting surface, and insert it into the cutting of the rootstock. Insert tightly to avoid slipping out.
After grafting, put it in a cool and ventilated place indoors to avoid sun exposure.
Pay attention to avoid rain and waterlogging, and prevent water in basin from rotting. At the same time, control the watering and keep the basin soil moist.
Fertilization should be accurate, do not apply fertilizer before survival, after grafting survival, a little low concentration, mature fertilizer can be. When fertilizing, do not pour it directly on the plant to avoid rotten stem.
In order to improve the survival rate, a large plastic bag can be put on the Christmas Cactus after grafting to increase the humidity and promote germination.
