Planting Methods and Key Technical Points for Pulsatilla chinensis
Pulsatilla chinensis is a perennial herb in the genus Anemone of the Ranunculaceae family, also known as Naihecao, Baitoucao, and Laogucao. It grows mostly 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 insects, 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 Pulsatilla chinensis be planted? Let's take a look.
1. Seed treatment
The propagation method for Pulsatilla chinensis is sowing. In June, when most of the seeds are ripe, they can be collected. After collection, the seeds are placed in the sun to dry. When drying, be careful to cover them with a layer of shielding material, such as gauze, because the seeds of Pulsatilla chinensis 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, 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. The seedbeds should have drainage ditches to facilitate irrigation and drainage.
3. Sowing
Before sowing, soak the seeds in warm water for 5-6 hours. After soaking, remove them and dry them, then wrap them in a linen bag and place them in a greenhouse at 25-30 degrees to germinate. Generally, they will germinate in 5 days, and when the germination rate reaches 70%, they can be sown. During germination, be careful to open the bag every day and break them apart by hand to release 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 facilitate 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 to prevent weeds from affecting seedling growth. Also pay attention to fertilizer and water management. During the rainy season, drain water promptly to prevent root rot. If the seedlings are not growing vigorously, apply 4-5 kg of urea per mu as a top dressing, and water promptly after fertilizing to avoid fertilizer damage. Generally, transplant in the second spring after the current autumn. When transplanting, control the plant and row spacing at 15×15 cm, and about 30000 plants can be planted per mu.
