It likes cool and dry climate. Cold resistant, drought resistant, not high temperature resistant. Sandy loam with deep soil layer and good drainage grows best, followed by alluvial soil and clay loam, while low-lying land with poor drainage is not suitable for planting.

Reproductive methods

Announce
edit

seed

Seed breeding is mainly used in production transplant The seeds are generally collected in the northeast in the first ten days of June, when 60% of the seeds become yellow and mature recovery The seeds are harvested too early, the maturity is not reached, and the germination is not strong; If the seeds are harvested too late, they will fly away with their own feathers. The collected seeds are placed in baskets to dry in the sun, and covered with screens to prevent the seeds from flying away with the wind. When drying to more than 98% dryness, put it on the iron mesh screen and rub it repeatedly until the seeds and feathers are crushed under the iron mesh. The seeds of Pulsatilla chinensis are very small. Generally, there are 500000 seeds per kg, sow Timely and properly, the budding rate can reach more than 80%.
The sowing in early spring is usually carried out in March and April, with a row spacing of 3.0-4.5cm. After sowing, the soil is covered to cover the seeds. In the early spring of the second year, before the overwintering seedlings sprout, the seedlings shall be transplanted according to the row and plant spacing of 30cm × 9cm. [3]

Ramet

When the old plant has not yet germinated, it shall be dug up by roots and planted separately. [3]

cultivation techniques

Announce
edit

Land selection and preparation

The sandy loam or loam with slightly higher terrain, sufficient sunlight, good drainage, loose and fertile soil shall be selected for cultivation; Saline alkali easily waterlogged, heavy clay soil is not suitable for planting. After land selection, fertilizer shall be applied according to the soil fertility, mainly with fully decomposed farmyard manure and less chemical fertilizer. Each mu (667 ㎡, the same below) shall be applied with 3000-4000kg farm manure and 30-35cm deep. Rake the soil to make a bed. The bed is 15-20 cm high and 1.0-1.2 m wide. Rake the bed surface to make a slightly convex bed surface for sowing. [3]

grow seedlings

Select new seeds collected in the same year, and prohibit old seeds. yes sprinkling irrigation Direct sowing can be carried out if conditions permit, and sowing can be carried out if there is no sprinkler irrigation condition germination Later sowing. Seed germination method: soak the seeds in warm water for 4-6 hours, change the water once during the period, drain the water after picking it out, and put it at 25-30 temperature for germination; During germination, the seeds should be properly turned to avoid heating; After 4-6 days, when more than 70% of the seeds have sprouted, they can be sowed; If the seeds cannot be sown in time, the germinated seeds shall be stored at 2-5 ℃. When sowing, the seeds shall be evenly sown on the bed surface according to the amount of 2.5kg seeds per mu, and then the seeds shall be covered by sieving fine soil with a sieve, generally covering about 0.2cm of soil, then watered thoroughly, and the bed surface shall be covered with straw, pine needles and other materials to facilitate moisture retention and seedling emergence. [3]

Administration

After sowing, the conditions are suitable germination In general, the seeds can sprout 4-5 days after sowing, and the seeds without germination treatment will sprout longer. After emergence, straw and other coverings shall be removed gradually, with half covering and half covering as the degree. When the true leaves grow out, spray the mixture of dimethoprim and foliar fertilizer to prevent sudden fall, once every 5-7 days, generally twice. In addition, urea can be applied twice according to the growth trend, and immediately watered after each application of 10kg or applied in the top rain before rain to prevent seedling burning. Weeding should be done early and thoroughly to prevent weeds and seedlings from competing for nutrients; Nongda can also be sprayed before emergence, but the spraying time should be well controlled. [3]

transplant

Pulsatilla can be transplanted in spring and autumn, either with 1-year-old seedlings of the same year or 2-year-old seedlings. As the anemone prefers dry and cool climate, the best choice for transplanting field is high dry land or sloping land. It can be used for bed transplanting or ridge planting. The plant and row spacing for bed planting is generally 10cm × 25-30cm, and the plant spacing for ridge planting is about 8cm. In case of drought after transplanting, it needs to be watered thoroughly after transplanting. The anemone is extremely drought resistant, so it basically does not need to be watered after seedling slowing without severe drought. Pulsatilla can tolerate barren, and nitrogen fertilizer can be applied properly at seedling stage; When bolting, the flower buds should be removed to facilitate root development; In the future, 10kg of compound potassium fertilizer can be applied per mu every year before returning to green, so as to accelerate root growth. [3]

Collection

commonly transplant In the next 2-3 years, after the ground part withers in autumn, the stubble on the ground is cut off, the main root is gouged out mechanically or manually, and the soil is removed to dry in the sun. The finished product is generally more than 1500-2000kg per mu of fresh Pulsatilla. [3]

Root rot

It is easy to occur in rainy season and low-lying Jiyong block Root rot Prevention and control methods: ① Before transplanting, soak the seed root with 100 times 50% disinfectant solution for 3-5 minutes before planting; ② During the rainy season in the growing season, attention should be paid to drainage to prevent ponding in the ground. ③ 50% Tobuzin 800 times of liquid. [4]

aphid

Suffer from aphid Harmful, mainly sucking young buds and leaves, especially in dry weather. Control method: 50% during aphid occurrence Fenitrothion Spray 1000-2000 times or 1500-2000 times of 40% dimethoate emulsifiable concentrates once a week until there is no aphid damage. [4]

Watch

There are more than 30 varieties of Pulsatilla with bell shaped flowers in three colors of white, purple and blue. The whole plant of Pulsatilla is covered with hair, which is very strange. During the month and a half from the opening of flowers to the maturity of capsules, you can enjoy the flowers first and then the fruits. In summer and autumn, the leaves are green and dormant after severe frost. As a kind of wild perennial plant, it can be planted for many years for viewing. It overcomes the disadvantages of high cost and easy degeneration of biennial herbaceous flowers. It can be planted in gaps between forests and bushes, or planted in flower border in a natural way. Because of its early flowering and short plant, it is an ideal ground cover plant variety, Feather style is persistent in fruit stage, which looks like a head and is very unique. It can also be used for flower beds or potted plants. In addition, because Pulsatilla is very sensitive to acid rain, when acid rain falls, Pulsatilla will soon die. This characteristic of Pulsatilla not only makes it often used as an indicator plant to detect environmental pollution, but also increases its value as an ornamental flower. [5]

Folklore

Legend 1: Mysterious Old Man and Pulsatilla
Once upon a time, in big lake There is a Niutou Mountain nearby. There is a village at the foot of the mountain. There is a young man called Po Po is cheerful, kind-hearted and helpful. Everyone likes him very much.
windflower
But one day, Po suddenly had a stomachache. The pain was more than ordinary and made Po's head ache Cold sweat , even hands and feet are cold. At that time, the people in the neighborhood went to work when they went up the mountain and down the ground. No one helped. Po couldn't bear the pain, so he had to cover his stomach and struggle to find the doctor in the next village. As soon as he walked out of the village, he could not support him and fell on the grass beside the road.
After a while, Po suddenly woke up and saw a white haired grandfather standing beside him with a stick. Grandpa asked Po why he was lying on the roadside. Po replied weakly, "My stomach hurts so much that I can't walk anymore." Grandpa said, "Then find some medicine to take." Po said, "Where can I find it?" Grandpa pointed to the grass beside Po with his stick. There was a green grass with white fur on its head, "The root of this grass is medicine. You can dig some back to make soup and drink it for several times." Po thought to himself, "This grass is common. There are many hills and fields. Can it really cure diseases? Grandpa didn't wait for Po to speak, as if he had seen through Po's question. He stroked his beard and said, "I am an old man with white hair. Will I lie to you?" Then he turned slowly and left.
Po decided to have a try. He resisted the pain and dug some of those heads Landrace Mao's green grass, when I got home, I boiled water from the grass roots, and my stomach didn't hurt much this night. After drinking for three days in a row, he recovered from his illness. When neighbors came to see Po, they knew that Po's illness had been cured by a grass root treatment.
Po recovered from his illness and went up the mountain to cut firewood. On the mountain road to cut firewood that day, Po met the white haired grandpa again. The grandpa stood there with a stick and spirit. From a distance, he looked like a mountain fairy with a white beard. Po hurried forward and said, "Thank you, Grandpa, the medicine you asked me to take is really good. I drank it for several times, and then my illness was cured quickly." The white haired grandpa smiled and said, "Young man, I was just going to tell you that it is my ancestral secret recipe. I saw that you are kind and willing to help people in the village. I wanted to lend your mouth to help me pass it on to the world." Po nodded and agreed. The white haired grandpa suddenly disappeared again.
Since then, no matter who the village people were, if they had stomach pain, Po would carry a shovel day and night to dig the green grass with white hairs on its head in the wild, and then use the grass roots to fry water for the patients to drink when they came back. After drinking, the stomach pain was cured.
Someone asked Po curiously what kind of medicine it was. When did Po learn to use herbs to treat his illness? Po was a kind man. He told everyone about his stomach ache and how he met the white haired grandpa. People asked where the grandpa had gone, and Po regretted: Yes, why didn't you ask the white haired grandpa where he lived?
The next day, Po ran to the place where he met grandpa for the second time and wanted to thank grandpa again. He could also ask for advice in person if he had anything to do in the future. [8] However, Po waited day after day for half a month and didn't see the white haired grandpa again.
Po was disappointed. He sat beside the mountain road where he met his grandpa for the second time, looking at the grass with many hairs growing on its head. Suddenly, he saw a light from a green grass with white hairs on its head. In the light, the green grass swayed gently against the wind. Po suddenly found: Oh, how like a white haired and bearded grandfather this grass is! Po knew that Grandpa with white hair might be an Antarctic fairy, coming down to teach secret recipes to cure people and relieve pain, right? Po also thought that we should not forget the old man who passed on the secret recipe. Since this kind of grass doesn't know its name, we might as well call it "Pulsatilla". Since then, there has been a herb called "Pulsatilla" in the world.
People are using "Pulsatilla" as a traditional Chinese medicine. In addition, they also make natural configurations or flower beds in gardens to beautify the environment.
Legend 2: Du Fu named this herb "Pulsatilla"
Legendary Tang Dynasty poets Du Fu When I was trapped in Beijing, my life was very hard. It was often: "The cup is not cold, but everywhere there is sorrow.". One morning, Du Fu drank a bowl of porridge left two days ago, and soon he vomited and suffered severe abdominal pain. But he lives in a cottage, penniless, and has no money to seek medical treatment. At this time, a white haired old man just passed by his house. Seeing this, he sympathized with Du Fu very much. After asking about his illness, he said, "Wait a moment, I will pick herbs for you." Soon, the white haired old man picked a handful of wild grass with white fur and fried it in soup for Du Fu to take. After Du Fu took the medicine, his pain gradually disappeared and he recovered after a few days. Since "no one asks about self pity for a white headed man, but pity for a person is a white headed man", Du Fu named the grass "white headed man" to express his gratitude to the white haired old man.
