Select more than one year of the stem, cut the top of the stem 5 cm to 6 cm or longer as the cuttings. Or cutting with a measuring ruler, the length of the cuttings should be 20 cm to 25 cm. Another way to choose is to take small branches from the Tianchi branch for cutting, pay attention not to be too young.
Vermiculite, pearl powder and pure river sand shall be selected for cutting measuring ruler without soil. It can be cut by single plant or multiple plants. Pay attention to the density between plants when cutting intensively.
The cut hyacinth of the ruler should be dried in the shade for a week first, and then cut after the incision is fully dried and the wound is healed, so it is easy to take root. As the slurry will flow out when cutting off the plug-in Cymbidium of the ruler, it can be closed with plant ash and put in the cool place for 7 to 10 days. Then insert it into the sand bed or soil, obliquely insert the soil, and let it take root. In the rooting period, water as little as possible, do not dry, do not water, wait for 30 to 40 days, then rooting. When the root is 3 to 4cm long, it can be transplanted to a small basin or directly planted in the open.
If there is a greenhouse, the ruler can be cutted all the year round. If there is no greenhouse, it can be cutted from May to September every year.
Cutting temperature should not be too high. When the temperature is over 35 ℃, cutting should be stopped to avoid failure, rotten roots or death.
Generally, part of the spring cutting ruler will bloom in the winter of that year, and the rest will bloom in the next year.
