What are the breeding methods of Artemisia selengensis? Artemisia selengensis can also be called Artemisia argyi, Shui Ai, Xiang Ai, etc. It is mainly distributed in Heilongjiang, Jilin, Liaoning, Inner Mongolia (South), Hebei, Shanxi, Shaanxi (South) and other places. , bead breeding, cutting propagation, seed breeding, etc., followed by a small series to specifically talk about the breeding methods and field management measures.
First, the main breeding method
1, ramets breeding
In May, the roots of Artemisia selengensis were dug up, cut off the young shoots, and then planted in the field according to the 40cm hole spacing. Generally, 1-2 plants were planted in each hole. After planting, the soil was covered and watered, about one week. survive.
2, bead breeding
In July and August, the semi-lignified stalks of Artemisia scoparia were cut off, and the young shoots were cut off, and then planted in the ground at a line spacing of 40 cm. The planting depth was about 6 cm, and the soil was kept moist.
3, cutting propagation
In June-August, cut the strong stalks of Artemisia selengensis, cut off the young shoots, and then cut the stalk into small pieces about 20cm long, inserted in the field, generally insert 4-5 roots each, the row spacing is 35cm × 30cm, after planting, the soil is covered and soiled, and it will be able to survive in about 10 days.
4, underground stem reproduction
Excavate the strong underground stems of Artemisia selengensis, cut the underground stems into small sections of 2-3 knots, bury them in the rafts, and then pour water.
5, seed live reproduction
In the first ten days of March, the seeds of Artemisia selengensis and the fine soil (3-4 times the amount of seeds) were evenly mixed and directly sown. Both sowing and stripping were possible, and the film was coated after sowing.
Second, field management measures
1. Site preparation
The planting place of Artemisia selengensis should choose the field where the medicinal crops have not been planted before, and the turf will be ploughed (frozen), and 3000 kg of high-quality decomposed manure will be applied per mu before planting to make 1.5-2 meters wide. Sorghum.
2, fertilizer management
Always keep the field moist. In the hot and dry season, water should be watered frequently. In September-October, before and after the shed, it is necessary to topdress once, and apply 5-10 kg of urea per mu, combined with watering.
3. Prevention and control of pests and diseases
The main pests of Artemisia selengensis are aphids, cotton bollworms, corn borers, etc., which can be controlled by high-efficiency, low-toxicity and low-residue pesticides such as yinbao and cadherin. At the same time, during the growth of Artemisia selengensis and after each harvest, it is necessary to carry out cultivating in time to promote the root development of Artemisia selengensis.
4, coverage
When the stem of the ground wormwood is dead by frost, it must be cut off the ground. At the same time, it is necessary to clean the garden, fertilize and pour water, and buckle the shed after about one week, and cover it with a floating surface of the film. Properly ventilate at noon every day to reduce the humidity in the greenhouse.
5, harvest
After 40-45 days after the stalk of the stalk, the plant height can be harvested when the plant height is 20-25 cm. When harvesting, cut the tender stems to the ground, keep the heart leaves, wipe off the remaining leaves, cover them to a cool place, and soften them for 8-10 hours before they can be sold.
Rabies Vaccine (Vero Cell) for Human Use, Freeze-dried is a preparation of rabies fixed virus CTN-1V inoculated into Vero cell. After cultivation by bioreactor, harvest the virus suspension; further perform the concentration, inactivation, and purification. The vaccine is formulated by adding human albumin, dextran 40 and sucrose through freeze-drying process. The freeze-dried vaccine looks like a white crisp cake which turns into a transparent liquid after reconstitution, without any preservative. Active ingredient: inactivated rabies fixed virus. Excipients: Human albumin, dextran 40, sucrose, sodium chloride, potassium chloride, potassium phosphate monobasic, dibasic sodium phosphate. Diluent for vaccine: sterile water for injection. The specification is 0.5ml/vial after reconstitution. 1 vial (0.5ml) per single human dose. The vaccine titer should be not less than 2.5IU.
