Fertilization of the land
It is advisable to choose neutral or slightly acidic loam soil with deep soil layer, loose and moist, rich organic matter, convenient drainage and irrigation, and good water and fertility retention. Before sowing, the soil was turned deeply, and 1000 kg of decomposed manure was applied per mu.
Hsiang-hsien
Artemisia chrysanthemum plants are small and have a short growth period, so they can be intercropped and intercropped with other vegetables. In production, live broadcast is mostly used, and both spreading and stripping can be used. 4 kg ~ 5 kg of seeds per mu for sowing. Strip sowing is 2 kg ~ 2.5 kg per mu, and the row spacing is 10 cm. In order to promote the emergence of seedlings, soak the seeds in warm water at 30 degrees Celsius ~ 35 degrees Celsius for 24 hours before sowing, remove them after washing and put them at 15 degrees Celsius ~ 20 degrees Celsius to promote germination, rinse with water every day, and sow seeds when the seeds are white after 3 days ~ 4 days. After sowing, it is covered with film, and the water is properly controlled after the emergence of seedlings, and the appropriate temperature is maintained to promote the healthy growth of seedlings.
Field management
Keep the soil moist after sowing and before the emergence of seedlings, and the seedlings can be ready in 6~7 days. After sowing and seedling, watering should be properly controlled, and seedlings should be thinned when there are 2~3 true leaves. For the sown seeding, the seedlings of Artemisia macrophylla are 6 cm square, and the seedlings of Artemisia mid-leaf or fine-leaved Artemisia are 3 cm ~ 4 cm square, and the spacing of Artemisia macrophylla is 5 cm, the distance between the plants of Artemisia mesophylla is 4 cm, and the distance between the plants of Artemisia fine-leaved is 3 cm. Adequate water supply to keep the soil moist. When the plant height is about 10 cm, it will chase 1~2 times of fast-acting nitrogen fertilizer with water, and start harvesting when the plant height is about 20 cm. After the first cut, water and top dressing to promote the occurrence of side branches, and then harvest after 20~30 days. 500 kg of manure and 3 kg ~ 4 kg of urea are applied per mu.
Pest and disease control
The main diseases are blight, leaf spot and sclerotinia disease. In the prevention and control of blight, the focus should be on strengthening comprehensive agricultural prevention and control measures, and attention should be paid to sowing seeds at the appropriate time to prevent sowing too closely and seedlings from growing too long; chlorothalonil wettable powder can be used for pesticide control. In the prevention and control of leaf spot disease, crop rotation should be implemented and field management should be strengthened.
Insect pests and insect pests mainly include vegetable borer, aphids, etc., and the control methods are the same as those for cultivated vegetables, but it is necessary to avoid the application of high and toxic pesticides.
Harvest
It should be harvested at the right time. It can be harvested when the plant is 20 cm tall. Leave 2~3 leaves at the base of the stem to be cut to promote the occurrence of lateral branches.
