The excellent plant with exuberant growth and no diseases and insect pests was used as the mother tree. Cut the upper part of the outer semi-lignified shoots as cuttings. All cuttings were graded and bundled into small handfuls, and the base was wrapped with wet toilet paper and brought back to the room for cutting.

4. Cuttings treatment

Each cuttage was cut into 8-10 cm long, 2 leaves were retained in the upper part, half of the leaves were cut off, the upper end was cut into a flat mouth, and the base was cut into an oblique orifice, and then the base 3 cm was immersed in 5/100000 naphthalene acetic acid or 1/10000 No. 1 ABT rooting powder solution, which could be taken out after 1 hour.

5. Cutting operation

Cuttings should be divided into beds (segments) according to diameter grade. With a plant row spacing of 5 × 10 cm, the cuttings were pierced with wooden sticks as thick as cuttings, and then the 2 prime 3 of the cuttings was inserted into the hole to press the soil around the cuttings. Finally, the inserting bed was watered with 10,000 times carbendazim solution to disinfect the soil and keep moisture by water supply.
