Linyi Fertilizer Network Copyright
Artemisia selengensis is native to China and belongs to semi-hardy-tolerant vegetables. It prefers cold and humid climate conditions and can be planted in greenhouses all over the country. Linyi Fertilizer Network Copyright

1 temperature. Artemisia selengensis has a wide adaptability, and the living environment likes a cool environment and is not resistant to high temperatures. The most suitable temperature for growth is 17-20 °C, slow growth below 12 °C, poor growth above 29 °C, but can withstand short-term zero-degree low temperature, seeds can germinate above 10 °C, but the fastest germination at 15-0 °C.

2 lighting. Artemisia selengensis is not strict with light requirements, and generally grows well under weaker light conditions. Under long daylight conditions, vegetative growth is not sufficient. Linyi Fertilizer Network Copyright

3 moisture. Artemisia scoparia is not strict with water and fertilizer requirements. As long as the soil is kept moist, if too much water will affect growth and development, the yield will be reduced. Linyi Fertilizer Network Copyright

4 soil. Artemisia selengensis has a wide range of adaptation to the soil, and the requirements are not strict, but it is best to use loose and fertile slightly acidic sandy loam. Linyi Fertilizer Network Copyright

Second, the cultivar of Artemisia scoparia var .
Linyi Fertilizer Network Copyright
According to the size of the leaves, Artemisia selengensis is divided into two types: Artemisia scoparia and Artemisia scoparia. Artemisia scoparia is more resistant to cold, rich in flavor, thin in twigs, fast in growth, early in maturity, and 40-50 days in growing season. The disadvantage is low yield. Artemisia scoparia, also known as Artemisia scoparia, has broad leaves and high yield. The shoots are short and thick, with few fibers and good quality. The shortcomings are slow growth and late maturity. It is now generally preferred to cultivate Artemisia scoparia, because Artemisia scoparia is not only good-looking but also has a high market price. Linyi Fertilizer Network Copyright

1Selection of land preparation Linyi Fertilizer Network Copyright
Linyi Fertilizer Network Copyright
It is advisable to choose a neutral or slightly acidic soil with deep soil layer, loose and moist soil, rich organic matter, convenient drainage and irrigation, and good water retention and fertility. Apply the base fertilizer before planting, apply 50-60 kilograms of compound fertilizer per acre, or apply 2000 kilograms of organic fertilizer per acre. It is also possible to apply 15 kg of urea per acre, add 25 kg of diammonium phosphate and 5-10 kg of potassium sulfate, and mix the fertilizer with the soil thoroughly.

2 Do the Linyi Fertilizer Network Copyright
Linyi Fertilizer Network Copyright
When doing sputum, it is generally required to be about 1.5-1.8 meters wide, and the length can be flexibly controlled according to the actual situation of the greenhouse. Use the hoe to make the soil fine and flat. Then you can sow. Linyi Fertilizer Network Copyright

3 soaking seeds, germination, Linyi fertilizer network

Artemisia argyi seeds are botany called achenes and have angular edges. 3-4 days before sowing, germination, soak the seeds in warm water at 30 ° C for 24 hours, then rinse and dry, germination at 25 ° C, wash once a day, seeds 3-4 days later Budding can be planted.

4 sowing Linyi Fertilizer Network Copyright
Linyi Fertilizer Network Copyright
Because the plants of Artemisia selengensis are small and have a short growing season, they can be intercropped with other vegetables. Production can be carried out by live broadcast, broadcast and broadcast. Spreading is generally 3-4 kg per acre. The amount of seed used per acre is 1.5-2 kg, which is more economical. When the line is broadcast, the line spacing can be controlled at about 10 cm. If the seedlings are transplanted, the seeds can be spread more densely, and they should be transplanted without being transplanted, so as not to waste time and seeds.

After the sowing is completed, cover the seed with a layer of 1 cm thick soil, flatten it with a flat surface, and then pour it once. Watering will be done every 10 days in the winter and watering every 7 days in the summer. Linyi Fertilizer Network Copyright

Artemisia scoparia can be emerged in a week or so after sowing. When the seedling grows to 2-3 true leaves, the seedling should be carried out. When the seedlings are in use, be careful not to use the sickle, directly use the seedlings to pull up the dense seedlings, leaving the seedlings The row spacing of the plant is kept at 4-6 cm. Note that it should not be too thin, otherwise it will affect the yield. Linyi Fertilizer Network Copyright

6 transplanting Linyi Fertilizer Network Copyright
Linyi Fertilizer Network Copyright
Practice has proved that transplanting is a good way to cultivate Artemisia argyi. The transplanted seedling grows faster than the live seedling, and the plant is large, and it can be harvested in about 20-25 days. When transplanting, use a sickle to start the seedling and put it into the prepared pot. Then transplanted into the whole good ground, the row spacing is about 4-6 cm. After transplanting, it should be poured once, and the nitrogen fertilizer should be applied once every 20 days after transplanting. Linyi Fertilizer Network Copyright

7Water Management Linyi Fertilizer Network Copyright
Linyi Fertilizer Network Copyright
Due to the low temperature in winter and spring, watering should be properly controlled after emergence to prevent rickets and downy mildew. Watering should be done according to the seedlings, usually watering once every 7-8 days. Linyi Fertilizer Network Copyright

8 Topdressing Linyi Fertilizer Network Copyright
Linyi Fertilizer Network Copyright
Generally, when the seedling grows to about 10-12 cm, it needs to be topdressed once. After each harvest, it will catch up with the fertilizer once. Topdressing is generally carried out with water and topdressing. The fertilizer is evenly spread in the water inlet, and directly irrigated with water. The fertilizer can not be directly sprinkled in the ground to avoid burning the leaves of Artemisia argyi. During the growth period, the water is chased 1-2 times of quick-acting nitrogen fertilizer, and each time the urea is used for 15-20 kg per mu. Linyi Fertilizer Network Copyright

9 pests and diseases control Linyi Fertilizer Network Copyright
Linyi Fertilizer Network Copyright
Artemisia selengensis is prone to anthracnose and downy mildew, and if it occurs, it can be sprayed with 72% of Plex 1000 times. If there are mites, spray 10% imidacloprid 1200-1500 times solution. Linyi Fertilizer Network Copyright

10 mining Linyi Fertilizer Network Copyright
Linyi Fertilizer Network Copyright
When the strain of Artemisia selengensis is as high as 20 cm and has 12-13 true leaves, harvesting is started, and harvesting should not be too late, so as not to affect the quality. When harvesting, you can use a knife to leave 2-3 leaves at the base of the stem, then remove the yellow leaves and sell the wormwood into small pieces for sale. It can be harvested once every 20-25 days, and it can be harvested 2-3 times each time. Linyi Fertilizer Network Copyright
