The attention should be paid to the cultivation of Artemisia selengensis

For soil preparation, it is advisable to choose a neutral or slightly acidic loam with deep soil, loose and moist soil, rich organic matter, convenient drainage and irrigation, and good water retention and fertility. Deeply turn the soil before sowing, and apply 1000 kg of manure per mu. It is made into a high compartment with a width of 1.5 meters and a groove depth of 20 to 25 centimeters.

Planting Artemisia argyi has small plants and short growth period, which can be intercropped with other vegetables. Live production, broadcast and broadcast can be used in production. Spread 4 to 5 kg per acre. The seeding is 2 to 2.5 kg per mu and the row spacing is 10 cm. In order to promote emergence, soak seeds with warm water of 30 ° C ~ 35 ° C for 24 hours before sowing, remove and wash under 15 ° C ~ 20 ° C conditions, rinse with water every day, after 3 to 4 days when the seeds are white. In the spring, we choose to plant in sunny days, cover with film after sowing, properly control the water after emergence, maintain the appropriate temperature, and promote the seedlings to grow vigorously. The temperature in summer and autumn is high, and it is covered with a covering such as a sunshade film after sowing to keep the soil moist. The seedling stage should be timed to ensure that the seedlings have a certain nutrient area.

The field management keeps the soil moist after sowing until the emergence of the seedlings, and the seedlings can be planted in 6 to 7 days. After winter and spring sowing, the watering should be properly controlled, and the seedlings should be carried out when the seedlings are 2 to 3 true leaves. Spreading, 6 cm of Artemisia scoparia, 6 cm square, staying strong seedlings, middle leaves or Artemisia scoparia, 3 to 4 cm square, and seedlings; strips, large leaves of Artemisia scoparia, 5 cm, middle leaf Artemisia scoparia, 4 cm, Artemisia scoparia, 3 cm. Adequate water supply to keep the soil moist. When the plant height is about 10 cm, the nitrogen fertilizer is chased 1 to 2 times with water, and the harvest is started when the plant height is about 20 cm. After cutting the first knife, watering and topdressing will be carried out to promote the occurrence of side branches, and harvest after 20 to 30 days. Each time the mu is used to apply 500 kg of manure and manure, and 3 to 4 kg of urea.

Pest control 1. Disease. The main diseases are blight, leaf spot and sclerotinia. In the prevention and control of blight, it is important to strengthen comprehensive agricultural control measures, pay attention to timely planting, prevent over-slipping, and grow young seedlings; chlorhexidine WP can be used for chemical control. Leaf spot disease, prevention and control should be carried out to strengthen field management. 2. Pests. Insect pests mainly include rapeseed meal, aphids, etc. The control methods are the same as general cultivation vegetables, but it is necessary to avoid the application of high and poisonous pesticides.

Harvested at a timely height of 20 cm. Two to three leaves were cut at the base of the stem to promote the occurrence of collaterals.
