Cultivation techniques and management methods of Artemisia selengensis. The planting time of Artemisia selengensis is also called basil and wormwood. Native to China. The edible part is tender stem, rich in nutrients, low in fiber, excellent in quality and unique in flavor. It is a kind of spice in vegetables, and it is also an indispensable refreshing dish in fast food industry, hot pot city and buffet. Artemisia scoparia is not only pleasant in taste, but also easy to cultivate. It grows fast and has a short cycle. It can be used as a pre- and post-cultivation for the main crops in the protected area, and it can be cultivated and interplanted.
The planting time of Artemisia selengensis has a special scent of scent and has a unique repellent effect on pests and diseases. Therefore, pesticides are rarely sprayed, which is an ideal pollution-free vegetable. It is a semi-hardy-tolerant vegetable, which is beneficial to its growth when it is cold and mild, and the relative humidity of the soil is maintained at 70%-80%.
Under the conditions of suitable temperature, the annual can be planted. In recent years, the cultivation of protected areas in winter, spring and autumn is more and more common. After sowing, the harvest is generally 40--50 days, and when the temperature is low, the growth period is extended to 60--70 days.
- Planting time is generally good in spring and autumn. It can be cultivated in the south, and can be cultivated in spring, autumn and winter.
- The sowing method can be broadcast live, or seedling transplanting, mostly based on live broadcast. Spread the seeds evenly on the culture soil. After sowing, cover the soil with a temperature of about 1 cm, pour water, and keep warm. It can be emerged in 4-5 days. When the seedling grows to 2-3 true leaves, it is necessary to have seedlings.
- Seeding utensils are planted on the balcony, roof, or courtyard. The cultivation containers are optional, such as flower pots, tubs, professional cultivation boxes, foam plastic boxes, etc. The depth of the ploughing layer is 20 cm.
Method of planting Artemisia selengensis
- Temperature: The growth temperature of Artemisia selengensis is 17-20 °C. The early spring planting season is relatively cold, accompanied by the phenomenon of cold spring. Therefore, it is necessary to cover the mulch or the old shed film on the sorghum surface after sowing, and compact it with soil, cold insulation and heat preservation. The weather turned warmer and the seedlings were uncovered before the apex film. When the protected area is planted above 25 °C, open the vent to release the air.
- Weeding between the seedlings: When the seedling grows to about 10 cm, the leaflets are pulled out according to the plant and row spacing of 3--5 cm, and the large leaf species are pulled out at about 20 cm, and the weeds are removed.
- Watering and fertilizing: After the seedlings are unearthed, watering begins, and the time and frequency of watering should be flexibly controlled to keep the soil moist. 10 times to 15 days before harvesting, 1 quick-acting nitrogen fertilizer was applied, and 15 kg of potassium nitrate and 8 kg of urea were applied per mu.
The pest control of Artemisia selengensis is mainly based on agricultural control. It should be rationally fertilized and watered to avoid sudden and small fluctuations; temperature management is not high and low, creating a good ecological environment, promoting healthy plant growth, reducing pest and disease damage and pesticide application. To maintain ecological balance.
Harvesting method of Artemisia selengensis When the seedling grows to a height of 18-20 cm, the leaflet is cut off on the ground at one time, and the roots are washed and bundled into small pieces. The harvest of Artemisia scoparia is relatively flexible. It can be harvested at one time. It can also be harvested several times with one seeding. When harvesting, leave the base of the main stem 4--5 leaves or 1--2 side branches, hand rub or knife. Cut the young main branch or side branch, bundle it into the market, and smash it once every 20 days. Watering and topdressing in time for each time to promote the germination of the side branches.
Artemisia selengensis is generally cultivated in flat sorghum, and can be sown or spread. Spring sowing uses soaking seeds for germination. The sowing method adopts the wet sowing method, first watering the bottom water, sowing after the water is infiltrated, and covering the soil with a thickness of 1 cm. The following is a brief introduction of the planting technique and management method of Artemisia selengensis!
It is advisable to cultivate sandy earth lobe in the ground preparation of the ground, and it is necessary to have convenient irrigation conditions, choose the ground and turn the ground, and apply good farmyard manure. Apply 1000 kg per 0.1 hectare and 25 kg of diammonium phosphate as base fertilizer. It is made of flat 1.2 to 1.4 meters wide and 10 to 20 meters long, ready for planting.
Sowing and seedling
- Seed treatment: 3 to 4 days before sowing, the seeds are soaked in 50~55 hot water for 15 minutes, soaked for 12~24 hours, placed in a warm place around 25 °C to germination, and washed once a day with water. If the new seed is to be placed at a low temperature of 0~5 °C in advance, the dormancy is broken in about 7 days.
- Seeding selection: Spring protected field cultivation is generally carried out in late March or April with seedbed seedlings: spring open field cultivation, seeding seedlings in hotbed in mid-April; direct field cultivation in spring, deduction of small arch shed or mulch in early May, summer, In autumn cultivation, it can be planted in batches in cold bed or open field, and a sowing date in 7~10 days.
- Seeding method: Visual cultivation method (live seeding or seedling transplanting) is carried out by spreading or seeding. The amount of seed per hectare is 60-70 kg. The seeding is planted at a row spacing of 10 cm. The seed amount per hectare is 30~37.5 kg. Early spring seedbed Seedlings should be covered with medicinal soil to prevent sudden death. The seedling age is preferably 20~0 days, and 3~4 true leaves are suitable for colonization.
Planting and field management sowing to germination and emergence usually takes 5-7 days. Pay attention to moisturizing during the germination to prevent the soil from drying out. When the seedling height is 2~3 cm and 1~2 true leaves, the seedlings and the field are removed, so that the plant spacing is kept 1~2 cm.
And shallow cultivating, until the seedlings are planted in 3~4 true leaves, the temperature of the outside or shed in the planting should be stable through 10 °C. The planting or seedling spacing should be 4-6 cm. Watering once during the first seedling, watering after the seedlings are fixed, and the nitrogen fertilizer is quickly applied with water. In the future, it can be harvested separately.
The harvesting of Artemisia selengensis is generally 40 to 50 days. When the plant is as high as 20 cm, 12 to 13 true leaves can be harvested. In order to keep the product fresh and tender, the harvest should be carried out in the morning. If the harvest is not timely, the temperature will be high, which will lead to aging of stems and leaves, poor quality, or elongation between nodes, and bolting flowers. If you want to harvest it multiple times, you can use a knife to cut 2~3 cm at the base of the main stem, and cut the tender stems and leaves into 0.5 kg. Watering after cutting, can be harvested again after one month.
