Seedling raising techniques of Codonopsis pilosula

Codonopsis pilosula is not only one of the most important traditional Chinese medicine in China, but also the main source of income for many farmers. it not only sells well among us, but also enjoys a high reputation in the international market. So how to raise seedlings when planting Codonopsis pilosula? Let's take a look at it with the editor.

1. Seed harvesting

Codonopsis pilosula, whether it is direct seeding or seedling transplanting, usually blossoms and bears fruit in the same year, but the one or two-year-old Codonopsis pilosula has a high seed setting rate and full grains. The maturation time of Codonopsis pilosula seeds is generally in the middle of October, and should be harvested in time when the seeds turn brown. Cut the plants from the ground during harvest, dry them in the sun, thresh them, store them in a dry environment, and wait for sowing in the following year.

2. Soil preparation and fertilization

Before raising seedlings, the plots with deep soil layer, flat terrain, good drainage and strong water and fertility conservation should be selected, and the good terraces should be selected instead of the plots with many weeds in the previous crop and serious underground pests. The seedling land should be cultivated carefully, the ground should be flat and loose, and fertilization should be carried out after soil preparation in order to ensure the robust growth of seedlings. Generally, 4000-4500 kg of rotten farm manure is applied per mu, and some chemical fertilizers are applied appropriately, then there is no need to apply fertilizer.

3. Ensure seedling raising.

Codonopsis pilosula can be sowed and raised seedlings in spring and summer, sowing is about 2-2.5 kg per mu, and the sowing depth is between 2-3 cm, which means that the top soil force of Codonopsis pilosula is weak, and it will be difficult to emerge seedlings if sowing too deep, so it is necessary to loosen the soil before sowing. After sowing, straw or farm manure can be covered with a thickness of 2-3 cm, which helps to keep warm and moisturize and prevent the sun.

4. Field management

Codonopsis pilosula seedlings grow thin, afraid of the sun, afraid of early, so according to the growth characteristics of ginseng seedlings, corresponding measures should be taken, such as timely watering when soil moisture is insufficient, sprinkler irrigation can be adopted to ensure that the seedlings are neat and strong. After the seedlings grow up, they can be watered directly, but the amount of water should also be controlled. Too much water will cause branches and leaves to grow, and it should be drained in time in the rainy season to avoid stagnant water retting roots. When ginseng seedlings grow to 6-8 cm, weeding for the first time, weeding should be careful, do not hurt the seedlings, but also to control underground pests.
