Light stem chrysanthemum is a nutrient rich vegetable, and its planting method mainly includes the following steps: 1. Soil preparation
1. Soil selection: Artemisia scoparia prefers warm and humid environments and does not have strict soil requirements, but fertile soil is beneficial for high yield and quality. It is advisable to choose land with pollution-free air and water sources, deep soil layers, loose soil, rich organic matter, and good drainage, preferably sandy loam or fertile muddy soil.
2. Fertilization: Add an appropriate amount of organic fertilizer, such as decomposed farmyard manure, to the soil, and apply 30~50 kilograms of compound fertilizer per mu to meet the nutrient requirements for the growth of Artemisia scoparia. 2、 Sowing seeds
1. Sowing time: Chrysanthemum morifolium is usually sown in spring or autumn, and can be sown every year under suitable temperature conditions. After sowing, the harvest usually takes 40 to 50 days, and the growth period can be extended to 60 to 70 days when the temperature is low.
2. Seed treatment: Before sowing, the seeds can be treated, such as soaking them in warm water at around 20 ℃ for 12 to 24 hours, then rinsing them with clean water 2 to 3 times, draining the water, and promoting germination. When promoting germination, the seeds can be placed at 20 ℃~25 ℃ and cleaned every 1~2 days. After 5~7 days of germination, they can be sown.
3. Sowing method: Sowing or strip sowing can be used. When sowing, the sowing rate per square meter should be 0.2 \ \~0.3 kilograms. After sowing, the seeds should be compacted with wooden boards or tapping to ensure full contact with the soil. When sowing in strips, seeds should be sown at a row spacing of about 10 centimeters, with a planting amount of 30~37,5 kilograms per hectare. It is advisable to cover the soil with a thickness of about 1 centimeter after sowing, and water it thoroughly to keep the soil moist. 3、 Field management
1. Watering: The growth of bare stem chrysanthemum requires sufficient water. After sowing, it is necessary to water it in a timely manner and keep the soil moist. During the growth period, watering should also be done in a timely manner according to weather conditions and soil moisture to meet the water requirements for the growth of Artemisia scoparia.
2. Weeding and loosening soil: During the growth period of Artemisia scoparia, timely weeding and loosening of soil should be carried out to maintain soil looseness and reduce competition for nutrients by weeds.
3. Fertilization: In the early stage of the growth of Artemisia scoparia, appropriate amounts of nitrogen, phosphorus, and potassium fertilizers can be applied to promote plant growth. When the seedlings grow to 8~10 true leaves, they begin to enter the vigorous growth period, and the amount of fertilizer required increases. Therefore, it is necessary to strengthen fertilizer and water management. 4、 Disease and pest control
Chrysanthemum morifolium has a special fragrance and insecticidal effect, so it is rarely sprayed with pesticides. But it is also necessary to closely monitor the growth of plants, timely detect and deal with pest and disease problems. Comprehensive prevention and control can be achieved through physical, biological, and chemical methods. 5、 Harvest
When the bare stem chrysanthemum grows to a height of 15-20 centimeters, harvesting can begin. Generally, the whole plant is harvested, but it can also be picked leaf by leaf. To keep the product fresh and tender, harvesting should be done in the morning. If you want to harvest multiple times, you can use a knife to leave 2-3 centimeters at the base of the main stem, cut it, water it after cutting, and harvest it again after one month.
Through careful management of the above steps, high-quality and high-yield chrysanthemum can be planted.
