The method of propagation of Stemona

Baibu alias hundred root, nine double root, etc., are perennial herbs, its underground rhizome has the effect of moistening lung and relieving cough, killing insects and itching, mainly used to treat chronic bronchitis, pulmonary tuberculosis and parasitic diseases. So how do you reproduce a hundred herbs? Let's take a look.

1. Seed propagation

① seed treatment

Perennial herbs usually need to grow for 3 years to blossom and bear fruit. From July to September every year, its aboveground stems and leaves begin to wither and turn yellow, and the fruit will turn green to yellowish brown, which can be picked when planting near dark purple. For the seeds that blossom and bear fruit in the later stage will not mature, after the fruit is harvested, put it in a ventilated and dry place to dry for a few days, after the shell of the fruit is naturally cracked, the seeds will come off by themselves, then remove impurities, select and plant them, dry and store them in the sun.

Sowing and raising seedlings with ②

Sowing can be divided into spring sowing or autumn sowing, which is generally autumn sowing in the south and spring sowing in the north according to the climatic conditions of the south and the north. Spring sowing is carried out from March to April, using the method of raising seedlings in the seedbed, sowing in trenches according to the row spacing of 25 cm, the ditch depth is 7-9 cm, and the seeds are scattered evenly into the ditch. After sowing, thin dung water should be irrigated, covered with fine soil, and then covered with grass for heat preservation and moisturization. seedlings can emerge after about 15 days. after finishing the seedlings, the cover should be removed and the measures of intertillage weeding should be done. According to the growth height and time of the seedlings. Controlling the plant spacing of 2-3 cm and topdressing in time can transplant after one year of cultivation, while autumn sowing is carried out from September to October, the method is the same as spring sowing, seedling in the following spring, transplanting in autumn.

2. Ramet propagation

Asexual reproduction when ramet, every year after harvest, cut off a large piece of rhizome medicinally, leaving a small root for seed, the number of root buds on the small root of the rhizome, divided into hosts, each plant must have 1-2 strong buds, and also with 2-3 small roots. When planting, the row spacing is 25 × 25 cm, one plant is planted in each hole, and the root buds are planted upward and vertically, not obliquely planted alive. Autumn planting usually comes out in February of the following spring, and the seedlings can be completed 15-20 days after emergence. At this time, the management of seedling stage can be strengthened and transplanting can be done in autumn.

The above is the introduction of the breeding methods of Baibu. I hope it can help you. If you want to know more about it, please follow us.
