Today, I would like to talk about the cultivation points of Artemisia selengensis in early spring. First, fertilizing the land In combination with the soil preparation, 20-25 kg of diammonium phosphate, 10-15 kg of potassium sulfate and 25 kg of ammonium bicarbonate are formed. After deep turning and leveling, it is made into a flat raft of 1 to 1.5 m wide. Second, the selection of germination Varieties with strong cold resistance are good, and the average acre needs 1.5 to 2 kg. 3 to 5 days before sowing, soak the seeds in warm water at 30 °C for 24 hours, wash and dry, then germination at 15-20 °C, wash once a day with warm water, and seed after seed germination . Third, reasonable sowing There are two ways to sow: 1 broadcast Watering the bowl, soaking the seeds evenly after the water has penetrated, covering the soil 0.5 to 1 cm thick.  2 broadcasts Ditch the ditch in a distance of 15 to 20 cm in the raft, and the ditch is 0.5 to 1 cm deep. After the water is poured in the ditch, the seed is sown and then covered with soil. Fourth, strengthen management After sowing, the temperature is kept at 20 to 25 ° C during the day and 10 ° C at night. After emergence, it is suitable for 15 to 20 ° C during the day and 8 to 10 ° C for the night. When the seedlings grow to 1 or 2 leaves, the seedlings are planted, and the seedlings are kept between 4×4 cm, and the appropriate seedlings of the strips can be used. When the seedling height is 3 cm, watering is started. When the seedling height is about 10 cm, the water is topdressed with water, and the ammonium sulfate is 10-15 kg. Combined with watering and top dressing 1 or 2 times, 600 times of cytokinin is sprayed reasonably to increase yield and quality. Five, pest control If leaf blight, downy mildew, etc. occur, spray treatment with 72.2% Plucker or 72% or Kelu 800 times solution may be used.
