How much is the seed of Radix Pseudostellariae?

The seed price of Radix Pseudostellariae is about 40-50 yuan per jin, but it varies greatly due to the quality, variety, producing area and market of the seeds. The reproduction methods of Radix Pseudostellariae can be divided into seed propagation and rhizome propagation. Because the seed maturation is inconsistent, the capsule is not easy to be harvested because the seeds fall off naturally. Generally, seedlings are cultivated in situ after harvest, and rhizome propagation is often used in large area production. At the same time, Radix Pseudostellariae is susceptible to mosaic virus disease, which has a great impact on the yield, so it is best to choose the varieties with high resistance to mosaic virus.

Sowing method of Radix Pseudostellariae

1. Soil selection: Pseudostellaria heterophylla planted sandy loam with good soil fertility and irrigated conditions, clay and waterlogged stagnant water, and the previous crop is not suitable for tobacco cultivation.

2. Adequate basic fertilizer: before ploughing, prince ginseng evenly applied 50.6 cubic meters of high-quality soil fertilizer, 50kg of ammonium bicarbonate and 50kg of nitrogen, phosphorus and potassium compound fertilizer per mu.

3. Leveling the border surface: the ploughing depth of the plot of Pseudostellaria after fertilization is 20 cm, and after leveling, rake fine, according to the border distance of 180 cm to 200 cm, to make a table border with a height of 10 cm to 15 cm and a width of 130 cm to 140 cm, after leveling the border surface.

4. Sowing at the right time: Prince ginseng sowed seeds evenly on the border from October to November, and took soil from another border to cover it, with a thickness of 1 cm. The amount of seeds used for strip sowing and sowing per mu was about 5 jin.

5. Post-sowing management: after the prince participated in sowing, the border was covered with 8cm thick wheat straw, covered with nylon net, and some of the wheat straw was removed in early March of the following year, but a small amount of wheat straw was still left (can cover the strict border surface).

Weeding can be stopped in early May.

4. Timely soil cultivation: after emergence in early spring, Radix Pseudostellariae covered the furrow on the border and scattered it next to the plant to cultivate the soil, which is beneficial to the growth and development of the root, but the thickness should be less than 1.5 cm, otherwise the yield would be affected.

5. Drainage and irrigation: Prince ginseng is afraid of waterlogging, dredging ditches and draining in time during the rainy season and after heavy rain, but also afraid of early, watering should be paid attention to during severe drought, and the soil is often kept moist to promote root development.
