Pulsatilla is a perennial herb of the Ranunculaceae family. It is also known as Pulsatilla globulifere, which is also known as Prunella, Prunella vulgaris, Saxifrage, Chrysanthemum, Old Mangosteen, Old Crested, Cat's Paw. It is produced in most parts of the country, with large production in the northeast and Henan, Hebei, Shandong, Shanxi, and Anhui. Wildly distributed in hills, barren slopes and fields. Its bitter taste, cold; the stomach, large intestine; with Qingrejiedu, cooling blood Zhijing, dampness and insecticidal effect: Indications of hot dysentery, epistaxis, blood stasis, vaginal discharge, pruritus, hemorrhoids and hemorrhoids Hey. I. Botanical characteristics and biological characteristics Pulsatilla chinensis is a perennial herbaceous plant with a conical root and vertical veins; the whole plant is densely covered with white villous hairs, plant height 10–40 cm, usually 20–30 cm. Basal leaves 4-5, trisected, sometimes tri-leaved. Single flowering flowers, 3 to 4 cm in diameter, bracts in petals, 6 in 2 rows, blue-purple, outer white pilose; stamens numerous, bright yellow. Flowering from March to May, fruiting period from May to June. Pulsatilla prefers a cool, dry climate that is cold-tolerant, drought-tolerant, and not heat-resistant; sandy soils with deep soil and well-drained water have the best growth, followed by alluvial soils and clay loams, and poorly drained and poorly grown. plant. Second, cultivation and management 1. The breeding method. Pulsatilla is mainly propagated with seeds or propagated in different plants. 1 Seed breeding. Production mainly uses seedlings and transplants. Harvesting of seeds in the northeast is generally in early June, when 60% of the seeds are yellowed and matured. The seeds are harvested too early, the maturity is not reached, and the sprouts are not strong; if the harvest is too late, the seeds will fly away from their feathers. The harvested seeds were placed in a basket to dry in the sun and covered with a screen net to prevent the seeds from flying away. When drying to more than 98% of the dryness, rub on the iron mesh screen repeatedly until the seeds and feathers are crushed and dropped under the iron mesh. Pulsatilla seed is very small, generally there are 500,000 seeds per kilogram of seed, sowing is appropriate and appropriate, and the budding rate can reach more than 80%. Early spring sowing is mostly carried out in March-April. Drilling, row spacing is 3 to 4.5 cm. After sowing, soil is covered to cover the seeds. To the early spring of the second year, the wintering seedlings were transplanted by rows and 30 cm x 9 cm spacing before budding. 2 bred. When the old strain has not yet germinated, the roots are dug up and the ramets are planted. 2. Choose a site for soil preparation. Should be selected slightly higher ground, adequate light, good drainage, loose soil and fertile sandy loam soil or loam soil cultivation: easy saline-alkali, heavy clay land should not be planted. After the land is selected, fertilization will be based on the soil fertility, and farmhouse fertilizers will be mainly used to fully decompose and fertilizers will be less applied. Each year, 3000 to 4,000 kilograms of fertilizer are applied to farms, and the depth is 30 to 35 centimeters. The bed of clay is made into a bed with a height of 15 to 20 cm and a width of 1 to 1.2 meters. The bed is smashed with a forceps to make the bed convex and wait for sowing. 3. Nursery. Select new seeds harvested that year and disable old seeds. There can be direct sprinkling with sprinkler conditions, and no sprinkler conditions can be sowed after sowing. Seed germination method: Seeds soaked in warm water for 4-6 hours, change the water once, remove and drain the water, place on the place of 25~30~C to germination: during germination, the seeds should be turned properly to avoid fever; 4~6 days later , When more than 70% of the seeds emerge when the bud tip can be sown: If not timely sowing, the germination of the seeds should be stored under 2 ~ 5 °C conditions. When seeds are sown, 2.5 kg seeds per acre are used to sow the seeds evenly on the bed surface. Then the seeds are covered with a sieve and sifted soil, usually covered with about 0.2 cm of soil, and then irrigated with water, using straw, pine needles and other materials. Cover the bed to help moisturize and sprout. 4. Post-broadcast management. After sowing, the conditions are appropriate. The germinated seeds can be seeded 4 to 5 days after sowing, and the seeds that have not been treated with germination have a longer growing time. After the emergence, straws and other coverings are gradually removed, and the cover is half covered. When the true leaves are grown, they are sprayed on the foliar fertilizer with a moldy spirit to prevent damping-down. The spray is applied every 5 to 7 days, and the spray is usually performed 2 times. In addition, according to the growing trend of topdressing 2 times urea, each topdressing 10 kg immediately after the water or rain before the topdressing to prevent burning seedlings. Weeding should be early and thoroughly, so as to avoid weeds and seedlings competing for nutrients: it is also possible to spray Farma to weed before emergence, but it is necessary to grasp the timing of spraying. 5. Transplanting. Pulsatilla can be transplanted in spring and autumn. It can be used as a 1-year-old seedling or a 2-year-old seedling. Because Pulsatilla prefers a cool, dry climate, the best choice for transplanting fields is high-lying land or sloping fields. It can be transplanted in bed, or it can be planted in ridges, and the beds are usually planted in rows with a spacing of 10 x (25 to 30) centimeters. The ridge spacing is about 8 centimeters. After the transplanting, in case of drought, it is necessary to irrigate the plant after being planted. Pulsatilla is extremely drought-resistant, so no watering is required in the absence of drought after the seedlings are conditioned. Pulsatilla is resistant to barrenness, and nitrogen fertilizer may be applied appropriately at the seedling stage. When twitching, buds should be removed to develop the roots. Afterwards, each year before returning green, compound potassium fertilizer can be applied 10 kilograms per acre to facilitate the growth of the root system. 3. Harvest and processing. Usually 2 to 3 years after transplanting. After the autumn part of the ground withered, cut off the residual stems on the ground. Use the mechanical or artificial main root planing, remove the dirt and dry finished products, generally produce more than 1500 ~ 2000 kg of fresh Pulsatilla per acre.
