2. Treat the cuttings with white sugar aqueous solution. The concentration of grass flowers is about 2% ~ 5%; Woody flowers account for about 5% ~ 10%. Immerse the base of the cuttings in the above solution for about 24 hours, take them out, rinse the sugar solution with clear water, and then cut.
3. Dilute the medical vitamin B 12 for injection with 1 times of cold boiled water, immerse the base of the incision in it, take it out for about 5 minutes to dry for a while, and then cut the incision after the liquid medicine is sucked in.
4. For some flowers and trees that are not easy to take root, you can also peel the branches into rings or tie them tightly with iron wires during the growth period, so that a lot of nutrients can be accumulated in the parts such as ring cutting, and cutting along the parts such as ring cutting during the dormancy period can promote rooting.
5. Cut with the heel. When cutting camellia, osmanthus fragrans, fig and other flowers and trees, the base of the cuttings can carry several annual branches, which is convenient for rooting.
6. Increase the bottom temperature of the bed. If it is blocked, it can be placed on a radiator with wooden boards or fire resistance in winter. It is better to use electrothermal hotbed for cutting if conditions permit.
