What are the precautions for planting codonopsis?

Codonopsis belongs to the Campanulaceae family and is a perennial herbaceous plant. It is a commonly used traditional Chinese tonic medicine, and codonopsis is also a fairly commonly used Chinese medicinal herb today. It has the effects of tonifying the middle and benefiting qi as well as strengthening the stomach and benefiting the spleen. At the same time, it can also enhance the human body's immunity and has a certain therapeutic effect on dilating blood vessels and on the problem of decreased white blood cells caused by chemotherapy and radiotherapy. So how much do we know about the planting of codonopsis? Today the editor mainly talks to everyone about the precautions for planting codonopsis. Let's take a look together.

1. Planting conditions

For the conditions for planting codonopsis, the main things to pay attention to are the climate, light, soil, temperature, humidity and nutrients of the planting site. Codonopsis is suitable for growing in warm, humid yet relatively cool climatic conditions. It prefers shade and fears strong light, but it also needs a certain amount of light. Secondly, the soil of the planting site is best a sandy loam that is convenient for drainage and irrigation, has strong permeability and infiltration, has strong water retention, is loose in texture and rich in organic matter.

2. Seed treatment

Before planting codonopsis, seed treatment is needed. Generally, the method of soaking the seeds is used. When soaking the seeds, we should note that the temperature of the warm water is about 40 degrees, and soak until the water temperature is no longer hot to the touch. During the soaking process, we also need to stir continuously. Then take them out and put them into a gauze bag, and also rinse them with clean water about three times, then place them on a sand pile to promote germination. During the germination process, we should note that every three or four hours we need to pour water at a temperature of about 15 degrees over the gauze bag once. Generally, sowing can be carried out after about a week.

3. Time and density

In the process of planting codonopsis, the general seedling raising time is about one year, and then the transplanting time is what we need to pay attention to. Usually transplanting is carried out in spring and autumn, respectively from mid-March to early April and from mid-October to early November. When transplanting, we generally plant at a density with a row spacing of 30 cm and a plant spacing of 10 to 15 cm.

4. Topdressing and irrigation

After transplanting, watering should be carried out, as this can promote the growth of new roots. After the transplants survive, we should slowly reduce watering. If continuous rainy weather occurs, then the ditches should be dredged in time for drainage, so as to avoid excessive water causing the roots of codonopsis to rot. When topdressing later, it should be noted that fertilization is generally carried out when the seedlings are 15 cm tall. Fertilizing later is also rather troublesome, and fertilization is mainly based on manure and urine water.

5. Building supports and trellising

Because the stems, leaves and vines of codonopsis are relatively long, we need to build supports and guide the branches and leaves of codonopsis to grow on the supports. This can keep a certain degree of air permeability in the field, avoid the harm of some diseases and insect pests, and at the same time also play a role in increasing yield. Generally, when the codonopsis seedlings grow to about 30 cm, supports need to be built.

The above is all the content that the editor wants to share with everyone today. I believe everyone has also gained a certain understanding of codonopsis planting, and when planting codonopsis, they will also pay attention to these issues. Of course, I also hope that everyone's codonopsis planting will get better and better in the future.
