Planting method of Pulsatilla chinensis

Pulsatilla is a perennial herb of the anemone genus of Ranunculaceae, which is also known as Nai he Cao, Bai Tou Cao and Lao Gu Cao. It is mostly wild in hills, barren slopes and fields. It has the efficacy of heat-clearing and detoxification, cooling blood and stopping dysentery, dryness and insecticidal effect, and has high medicinal value. With the increase of demand, a large number of mining destroyed its growth environment, so wild resources continue to reduce, can no longer supply the market demand, only through artificial planting to meet the demand. So how should Pulsatilla grow? Let's take a look.

1. Seed treatment

The reproduction method of pulsatilla is to sow seeds. In June, when most of the seeds are ripe, they can be collected, and the collected seeds are placed in the sun to dry. When drying, you should pay attention to cover a cover, such as a screen, because the seeds of Pulsatilla are small and easy to be blown away by the wind. After drying, knead the seeds slowly and separate the seeds from the feathers.

2. Land preparation

When planting, the land with higher topography should be selected, which requires that the soil is rich, loose and sandy with good drainage permeability. After selecting the plot, the soil should be prepared, the soil should be ploughed to make it loose, and 2000 kg of farm manure per mu should be applied as base fertilizer to turn it into the soil. Can also be sprinkled with 1 kg of methamidophos per mu to prevent diseases and insect pests, after ploughing, it will be leveled, depending on the planting scale to do seedbed, seedbed to do a good drainage ditch, so as to avoid drainage and irrigation.

3. Sowing seeds

Soak the seeds in warm water for 5-6 hours before sowing, soak them out and dry them, wrap them in sacks, put them in a greenhouse of 25-30 degrees to promote germination, generally germinate in 5 days, and sow seeds when the germination rate is 70%. When sprouting, you should pay attention to open it every day and use your hands to disperse heat, so as to prevent the seeds from dying due to excessive heat accumulation. Sowing seeds evenly on the seedbed, generally 2.5kg per mu, after sowing covered with a layer of fine soil, the thickness of 0.5cm or so, in a permeable watering, covered with a layer of grass heat preservation teacher, in order to facilitate emergence.

4. Field management

Seedlings will emerge 3-4 days after sowing, then the cover grass should be removed in time, and then watered to keep the soil moist. Weeding should be done when the seedlings grow on three leaves, so as not to affect the growth of the seedlings. Also pay attention to fertilizer and water management, timely drainage in the rainy season to avoid rotting roots, seedling growth is not exuberant, can be applied urea 4-5 kg per mu, timely watering after fertilization, so as to avoid fertilizer damage. It is generally chosen to transplant in the spring of the second year after the autumn of that year, and the row spacing of 15 × 15cm should be controlled when transplanting, and about 30000 plants can be planted per mu.

The above is the planting method of Pulsatilla. I hope it can help you. If you want to know more about the planting of medicinal materials, please follow us.
