A detailed explanation of the planting methods and key techniques for crown daisy
Crown daisy, also known as tonghao, penghao, haocai, and chrysanthemum greens, is an annual or biennial herbaceous plant in the Asteraceae family. It is called crown daisy because it was a delicacy exclusively for the imperial court in ancient times. It calms the mind, nourishes the spleen and stomach, dissolves phlegm and fluids, and benefits the intestines and stomach. With the increase in planting area, it has gradually appeared on our dining tables. So how should crown daisy be planted? Let's learn about it together.
1. Site selection and land preparation
When planting crown daisy, it is best to choose fertile, loose, well-drained sandy soil, and good drainage and irrigation conditions are also required. After selecting the planting site, begin land preparation and plowing. During plowing, apply 500-600 kg of farmyard manure per mu as base fertilizer, then harrow it fine and level it, and make beds according to the terrain. Make flat beds on flat terrain and short beds on uneven terrain.
2. Seed treatment
The propagation method for crown daisy is seed propagation, but before sowing, the seeds must be treated to increase the germination rate. 3-4 days before sowing, soak the seeds in warm water for 10-20 minutes, and after the water cools, continue soaking for 1 day. Remove them and let them dry, then place them in a greenhouse at about 25 degrees for germination. During germination, wash them with water once a day to prevent the seeds from spoiling. If they are new seeds, give them low-temperature treatment to break dormancy.
3. Sowing
Sowing can be done in spring or autumn. In spring, direct seeding in the open field or sowing with plastic film can be used, while in autumn, cold frames or open-field sowing can be carried out in batches and stages. The sowing methods include broadcasting and drilling. Broadcasting generally uses 4-5 kg of seed per mu, while drilling is done with a row spacing of about 10 cm, and the amount of seed used is generally only half that of broadcasting. When sowing in early spring, cover with medicated soil to prevent damping-off disease. Seedling management generally lasts 20-30 days, and when the seedlings grow 3-4 true leaves, they can be transplanted.
4. Field management
After 5-7 days of sowing, they will germinate and emerge. When the seeds germinate, pay attention to moisture retention to avoid the soil being too dry, which is unfavorable for seed germination. When the seedlings grow 2-3 cm, thin them and pull out weak seedlings. The plant spacing for thinning should be kept at 1-2 cm. While thinning, cultivate and weed. When cultivating, plow shallowly to avoid damaging the root system. When the seedlings grow to 3-4 true leaves, transplant them, with a plant spacing of 4-6 cm. When thinning and setting the seedlings, water them to prevent the seedlings from dying, and also apply a topdressing of dilute liquid nitrogen fertilizer to make them grow quickly. When they grow to 20 cm, they can be harvested.
