Last Updated: 2024/11/05, The hardwood cuttage techniques of Metasequoia glyptostroboides are as follows: 1-3-year-old mother trees are selected to take cuttings or collect seed strips from round ears in spring, and 1-year-old seedlings and their lateral branches can also be used as cuttings. The survival rate of cutting cuttings in the tip and middle section of seed strips is higher, generally cutting cuttings 10 to 12 centimeters long, slightly cut into 15 to 18 centimeters long. Before cutting, soak cuttings with 50mg NAA per kg for 20 to 24 hours, or soak cuttings with 500mg NAA for 3 to 5 seconds, or soak them with 100mg ABT rooting powder per kg.

Hardwood cuttings, row spacing 8 to 12 cm by 18 cm or 7 to 10 cm by 20 cm. About 46 to 70 plants per square meter. The cutting depth is 7 to 8 cm. When the temperature reaches about 10 degrees Celsius, the winter buds in the upper part of the cuttings begin to sprout, and then new shoots or feathered leaves are drawn out one after another. Until late May, the cuttings had not taken root and were in a state of "false activity". Cuttings generally take root only when the temperature is stable above 20 degrees Celsius from the first and middle of June to the last ten days of June. During the period of "false living" and rooting, we should pay attention to water management, watering frequently, less quantity, keep the soil moist, but not too wet and cause the lower end of cuttings to rot.
