Propagation method of Polygonatum polygonatum
Rhizoma Polygonatum, also known as yellow chicken cabbage, pen tube vegetable, claw ginseng, is a medicinal plant with a long history of application in China. In modern medicine, it is one of the important raw materials of many kinds of proprietary Chinese medicine. at present, it has a very wide planting area all over the country, so how does it propagate when planting? Let's have a look with the editor.
1. Land selection and preparation
There are two main propagation methods of Polygonatum polygonatum: seed propagation and rhizome propagation, but if you want to improve the efficiency of reproduction, we must first choose a good breeding ground. In order to select the moist and fully concealed zone and the sandy loam with loose texture, good drainage and water and fertility conservation, it is appropriate to turn deeply before breeding to keep the soil loose, and some fertilizer can be applied appropriately to speed up seedling emergence.
2. Seed propagation
Seed treatment: the mature time of Polygonatum seed is in August, when the plant is budding, the plant with strong growth and free of diseases and insect pests should be selected as the remaining plant, and the remaining plant does not have any yield, while the remaining plant should remove the flower bud in time and save nutrients. The application of phosphorus and potassium fertilizer to the remaining plant can promote fruit development and grain fullness. When the seeds are ripe, the full-grained seeds of the mobile phone are treated with sand. after mixing the seeds and fine sand at 1:3, keep them moist in a pit 30 cm deep in the hide and shade.
Sowing: when preparing to sow in the second year, select it, trench the land according to the row spacing of 12-15 cm, spread the seeds evenly into the ditch, cover the soil about 1.5-2 cm, water after a little suppression, cover with film or grass, keep warm and moisturize, to facilitate seedling emergence. After the seedlings are unearthed, plastic film and cover grass should be removed in time, and time seedlings should be planted when the seedlings grow to 6-9 cm, and they can be transplanted after a year.
3. Rhizome propagation
In late autumn or early spring, the rhizomes of plants with strong growth and free of diseases and insect pests were dug up, and the young parts of the tip were selected and cut into several segments with 3-4 nodes in each section. After cutting, put it in a cool and ventilated place to dry, and then dig holes in the plot according to the plant spacing of 10-15 cm and row spacing of 20-25 cm. After planting, cover the soil and water it. In the future, several boats should be made every 3-5 days to keep the soil moist and facilitate seedling emergence.
The above is the introduction of the breeding method of Rhizoma Polygonatum. I hope it can help you. If you want to know more about it, please follow us.
