Seedling cultivation of Radix Pseudostellariae

The main results are as follows: 1. Prince ginseng is susceptible to mosaic virus disease, which has a great effect on yield. Therefore, it is best to choose the new variety of Pseudostellaria which is highly resistant to mosaic virus cultivated in Wendeng City.

2. Pseudostellaria heterophylla was cultivated in sandy loam soil with good soil fertility and irrigated condition. Clay and waterlogged water as well as tobacco plots in the previous crop are not suitable for cultivation.

3. Before fertilization and tillage, 5-6 cubic meters of high quality soil fertilizer, ammonium bicarbonate 50kg, nitrogen, phosphorus and potassium compound fertilizer 50kg were evenly applied per mu.

4. Make the platform border to plough the fertilized land deep 20cm, level it and rake it fine, according to the border distance of 180-200cm, make the platform border with a height of 10-15cm and a width of 130-140cm, and level the border surface.

5. Sowing from October 20 to November 20, sow the seeds evenly on the border surface, take soil from another border to cover, the thickness of 1cm. It can also open wide trenches on the border surface, row spacing 5-10cm, trench depth 1cm. The seeds were evenly sown in the ditch, then covered with flat, and the amount of seeds used for strip sowing and sowing per mu was 2.5kg. After sowing, the border is covered with 8-10cm thick wheat straw and covered with a nylon net to prevent the wheat straw from being blown away by the wind. The main function of grass cover is heat preservation, moisturizing and preventing soil from hardening. In the first ten days of March of the following year, get rid of some wheat straw, but still leave a small amount of wheat straw (can cover strict border surface), field management and commercial participation in the field.
