What are the latest planting methods for Chinese pulsatilla?
Chinese pulsatilla (Pulsatilla chinensis) is a perennial herb of the genus Anemone in the Ranunculaceae family, also known as Naihe grass, white-head grass, and Laogu grass. It mostly grows wild on hillsides, barren slopes, and in fields, and has the effects of clearing heat and detoxifying, cooling blood and stopping dysentery, and drying dampness and killing parasites, with extremely high medicinal value. As demand increases, large-scale digging has destroyed its growing environment, so wild resources are continuously decreasing and can no longer supply market demand. Only artificial cultivation can meet the demand. So how should Chinese pulsatilla be planted? Let's take a look.
1. Seed treatment
The propagation method for Chinese pulsatilla is sowing. In June, when most of the seeds are mature, they can be collected. After collection, the seeds are placed in the sun to dry. When drying, be careful to cover them with a shielding material such as gauze, because the seeds of Chinese pulsatilla are small and easily blown away by the wind. After drying, slowly rub the seeds to separate the seeds from the feathers.
2. Land preparation
When planting, choose a plot with higher terrain, and the soil should be fertile, loose, and sandy soil with good drainage and permeability. After choosing the plot, carry out land preparation by plowing the soil to make it loose. When covering, apply 2000 kg of farmyard manure per mu as base fertilizer and plow it into the soil. You can also spread 1 kg of phorate per mu to prevent pests and diseases. After plowing, level it and make seedbeds according to the planting scale. Drainage ditches should be made in the seedbeds to facilitate drainage and irrigation.
3. Sowing
Before sowing, soak the seeds in warm water for 5-6 hours. After soaking, remove and dry them, then wrap them in a hemp cloth bag and place them in a 25-30 degree greenhouse to promote germination. Generally, they will germinate in 5 days, and when the germination rate reaches 70%, they can be sown. When promoting germination, be careful to open them every day and use your hands to break them up and dissipate heat, so that the seeds do not die from excessive accumulated heat. When sowing, evenly scatter the seeds on the seedbed. Generally, 2.5 kg of seed is used per mu. After sowing, cover with a layer of fine soil about 0.5 cm thick, then water thoroughly once, and cover with a layer of grass to keep warm and promote seedling emergence.
4. Field management
Seedlings will emerge 3-4 days after sowing. At this time, promptly remove the covering grass, then water to keep the soil moist. When the seedlings grow 3 leaves, do a good job of weeding so that weeds do not affect seedling growth. Also pay attention to fertilizer and water management. During the rainy season, drain water in time to avoid root rot. If the seedlings are not growing vigorously, apply 4-5 kg of urea per mu as a top dressing, and water in time after fertilizing to avoid fertilizer damage. Generally, choose to transplant after the autumn of the same year or in the spring of the following year. When transplanting, control the plant and row spacing at 15×15cm, and about 30000 plants can be planted per mu.
