1、 Ramet propagation

The method of dividing plants is the most applicable in the family. It is also very simple and convenient to operate, and the survival rate is high. It can be operated in spring and autumn. The plant is required to be more than two years old. First take the plant out of the flower pot, then remove the soil from the root and trim the part of the rhizome. Find a good position and cut the rhizome from the base of the plant cluster to ensure that there are more than 3 bud points on each cluster. Prepare the appropriate basin soil, plant the divided plants separately, and then put them in the semi shade to adapt

2、 Sowing and propagation

The survival rate can be improved by obtaining seeds by pollination and then soaking the seeds in water to promote germination. Prepare a suitable substrate, which requires good ventilation and drainage, and put it in the sun in advance to achieve the effect of disinfection. Choose to sow in the greenhouse, cover it with a thin layer of soil after sowing, spray water frequently to keep it moist, or cover it with fresh-keeping film to keep it warm and moist, so as to promote the germination of seeds as soon as possible

3、 Tissue culture

Tissue culture is suitable for large-scale reproduction, which is generally difficult to achieve in the family. It mainly uses the leaves, inflorescences, stem tips and stem segments on the plant as containers to induce bud growth with hormones
