Artemisia selengensis is a semi-cold-resistant vegetable, and its light requirements are not strict. Generally, it is better to use weaker light. It is a short-day vegetable, which is conducive to its growth in a cool and mild environment with soil relative humidity maintained at 70%-80%. Under long-day conditions, vegetative growth does not develop sufficiently, and it quickly enters reproductive growth and flowers and seeds. Planting Artemisia halodendron need to pay attention to the following points in the greenhouse: First, sowing time: general marigold can be seeded 3-4 days after sowing, but if the weather is all fine in 3-4 days after sowing, and the temperature exceeds 32°C, then Artemisia halodendron emerges more difficult.
Therefore, we must understand the weather forecast before sowing, it is best to ensure that after sowing Artemisia lucidum will encounter 1-2 days of cloudy weather or slightly lower temperature, so as to ensure the normal emergence of Artemisia selene.
Second, the amount of seeding: If the weather is cold, the Artemisia halodendron will use 6-7 pounds of seed, and as the temperature rises, in order to prevent the dead seedling phenomenon, the seedlings of Artemisia halodendron should be appropriately increased sowing volume, available per mu. 8-9 pounds.
Third, watering: Artemisia halodendron after sowing, generally three water can be harvested. Follow the first water immediately after sowing. The second water is generally carried out about 10 days after emergence. However, the second watering time is not fixed, depending on the market price. If the market price is good, the second water can be poured a few days in advance so as to mention the morning market; if the market is not good, it can be poured in a few days later to delay the listing. Pour the third water one day before the harvesting of Artemisia halodendron for better quality.
Fourth, pest and disease control: In general, after the emergence of Artemisia selene vulnerable to bacterial blight and damping-off disease, should be sprayed immediately after the emergence of 15% antipyretic agent 450 times liquid. Http://Content/34bc6b6c-97f5-4a47-9e93-f16bd48ca6d1?cType=2
