Culture method of Pulsatilla chinensis

Soil

Pulsatilla is suitable for growing in soil with deep soil layer and good drainage, either sandy soil or clayey soil, and add enough base fertilizer.

Light and temperature

Pulsatilla likes the sun very much, but can not let the strong light shine directly on it. It is suitable to be born in a cool and dry environment. It has good cold resistance, but it is afraid of high temperatures. The most suitable growth temperature is 10 ℃-21 ℃. In summer, because the temperature is too hot and the light is too strong, we can't keep the plant in the sun. We should give it proper shade, put it in a cool and ventilated place, and sprinkle water around the plant. This can reduce the temperature around the plant and let the plant grow more healthily.

Winter temperature is too low, it is necessary to move the plant indoors for breeding, and maintain a certain temperature, so as to prevent the plant from frostbite due to low temperature.

Water and fertilizer management

Pulsatilla should combine watering and fertilization in breeding. Pulsatilla likes fertilizer and has no specific requirements for the variety of fertilizer. First of all, the plant needs to apply some basic fertilizer when setting the value. secondly, when the plant enters the normal growth, in order to be more conducive to the growth of the plant, it is necessary to apply rotten liquid fertilizer every half a month.

Watering is also needed when fertilizing, watering the soil thoroughly to keep the soil in a moist state, but be careful not to let stagnant water in the basin, otherwise it will lead to root rot, and in the process of breeding, it is necessary to strictly control the amount of watering and fertilization, otherwise it is very likely to make the plant grow too much, or make the plant blossom slowly.

After understanding how Pulsatilla is raised, let's take a look at the seed reproduction of Pulsatilla.

Grassy plains and low mountain slopes, forest edges, or dry rocky slopes. It is also distributed in Korea and the far East of the Soviet Union.

4. Identification

The root of Pulsatilla chinensis is long cylindrical or conical, slightly curved, sometimes twisted and slightly flat, 5-20cm in length and 0.5-2cm in diameter. The surface is yellowish brown or brown, there are irregular longitudinal wrinkles or longitudinal grooves, sometimes 2-3 roots are divided into 2-3 roots, the skin is easy to fall off and expose yellow wood, and the skin is often eroded into concave holes, with reticular patterns protruding longitudinally; the root head is slightly inflated, sometimes bifurcated, and the tip remains several layers of sheath-like petiole base and young leaves, densely white villi. The quality is hard and brittle, the folded section is slightly flat, yellowish-white, and sometimes there is a gap between the skin and the wood. The breath is slight and the taste is slightly bitter. It is better to have a thick and long strip with a solid quality. Microscopic identification of root cross section: epidermis, cortex and endodermis are usually exfoliated. The phloem is broad, the lateral cells are brown, and the walls are corky; the phloem fibers are scattered alone or in several bundles, with a diameter of 15-35 μ m, with thick walls, and some roots have no fibers.

6. Methods of reproduction

Seed breeding and transplanting are mainly used in seed propagation and production. Seeds are generally harvested in the northeast in early June, when 60% of the seeds are yellowed and ripe. If the seeds are harvested too early, they will not reach maturity and sprout; if they are harvested too late, the seeds will fly away with the wind with their own feathers. The harvested seeds are placed in baskets to dry in the sun and covered with screen screens to prevent the seeds from flying away with the wind. When the sun reaches more than 98% dryness, rub it repeatedly on an iron screen until the seeds and feathers are crushed and dropped under the iron net. Pulsatilla seeds are very small, generally there are 500000 1kg seeds, sowing is timely and appropriate, and the germination rate can reach more than 80%.

Sowing in early spring is mostly carried out from March to April, strip sowing, row spacing 3.0-4.5cm, covering the soil after sowing to cover the seeds. In the early spring of the second year, the overwintering seedlings were transplanted according to row and plant spacing 30cm × 9cm before sprouting.

When the old plant has not yet germinated, the roots are dug up and planted separately.

7. Cultivation techniques

Land preparation should choose sandy loam or loam with higher topography, sufficient light, good drainage, loose and fertile soil, and saline-alkali waterlogging and heavy clayey land should not be planted. After selecting the land, fertilizing according to the soil fertility, mainly applying fully mature farm manure and less chemical fertilizer. 3000-4000kg farm manure was applied per mu (667 mu, the same below), and the tillage depth was 30-35cm. The soil is raked fine and made into a bed with a height of 15-20cm and a width of 1.0-1.2m. The bed surface is held fine with a rake to make a micro-convex bed to wait for sowing.

The new seeds harvested in the same year are selected for seedling raising, and the old seeds are prohibited. Those with sprinkler irrigation conditions can be sown directly, and those without sprinkler irrigation conditions can be sown after budding. Seed germination method: soak the seeds in warm water for 4-6 hours, change the water once during the period, drain the water after being removed, and put it at a temperature of 25-30 to promote germination; turn the seeds properly during the germination period to avoid fever; after 4-6 days, when more than 70% of the seeds emerge from the bud tip, they can be sowed; if they cannot be sowed in time, the germinated seeds should be preserved under the condition of 2-5 ℃. When sowing, according to the amount of 2.5kg seeds per mu, sow the seeds evenly on the bed surface, and then cover the seeds with fine soil sieved by a sieve, generally covering the soil around 0.2cm, then pour water thoroughly, and cover the bed surface with straw, pine needles and other materials to protect moisture and seedling emergence. After sowing, the conditions after sowing are suitable, the germinated seeds can emerge 4-5 days after sowing, and the emergence time of the ungerminated seeds is longer. After emergence, straw and other mulch were gradually removed to half cover and half cover. When growing true leaves, spray chlorpromazine with foliar fertilizer to prevent quenching disease, spray once every 5-7 days, generally spray twice. In addition, urea can be applied twice according to the growth, watering immediately after each topdressing of 10kg or top rain before rain to prevent burning seedlings. Weeding should be early and thorough, so as to prevent weeds from competing with seedlings for nutrients; you can also spray Nongda weeding before emergence, but you should grasp the timing of spraying.

Transplanting Pulsatilla chinensis can be carried out in spring and autumn, either with 1-year-old seedlings or 2-year-old seedlings. Because Pulsatilla prefers dry and cool climate, it is best to choose high dry land or sloping land for transplanting. It can be used for bed transplanting or ridge planting. The plant and row spacing of bed cultivation is generally 10cm × 25-30cm, and the plant spacing of ridge cultivation is about 8cm. If there is drought after transplanting, it needs to be watered thoroughly after transplanting. Pulsatilla is extremely resistant to drought, so there is basically no need to water after slow seedling without severe drought. Pulsatilla is tolerant to barren, and nitrogen fertilizer can be applied properly at seedling stage; flower buds should be removed during bolting to facilitate root development; and compound potash fertilizer 10kg can be applied per mu before turning green every year to accelerate root growth.

Harvesting and processing are generally harvested 2-3 years after transplanting, and after withering on the ground in autumn, the residual stems are cut off, the main roots are planed out mechanically or manually, and the finished products are obtained by removing the soil and drying in the sun, which generally produces more than 1500-2000kg of fresh Pulsatilla per mu.

8. Disease and pest control

Root rot is prone to root rot in rainy season and low-lying land. Prevention and control methods: before transplanting, ① will soak the seed roots with 50% bacillus 100 times solution for 3-5 minutes before planting; drainage should be paid attention to during the rainy season during the ② growing season to prevent water accumulation in the ground. During the onset of ③, 50% topiramate was irrigated with 800x solution.

Aphids suffer from aphids in the process of plant growth and development, and mainly feed on tender buds and leaves, especially in dry weather. Control method: during the occurrence of aphids, 1000-2000 times of fenitrothion or 1500-2000 times of dimethoate EC were sprayed once a week until there was no harm to aphids.

9. Main value

There are more than 30 varieties of ornamental pulsatilla, with bell-shaped flowers, with three colors of white, purple and blue. The whole plant of pulsatilla is covered with hair, which is very peculiar, from the blooming of flowers to the ripening of the capsule for one and a half months. In summer and autumn, the leaves are green and dormant after severe frost. as a wild perennial plant, it can be cultivated for many years a year, overcoming the shortcomings of high cost and easy degradation of herbaceous flowers in 2012. it can be planted in the forest gap and shrubs in the garden, or in the flower border in a natural way. because of its early flowering period and short plant, it is an ideal variety of ground cover plant, and the feathered style is persistent in fruit, such as head-shaped style. Very chic. It can also be used in flower beds or potted plants. In addition, because pulsatilla is very sensitive to acid rain, pulsatilla dies quickly when acid rain comes. This characteristic of pulsatilla not only makes it often used as an indicator of environmental pollution, but also increases its value as an ornamental flower. Medicinal pharmacological action

1. Anti-amoeba: pulsatilla decoction and its saponins can inhibit the growth of amoeba histolytica in vitro and in vivo, but large doses are needed. In the in vitro experiment, the decoction could completely inhibit the growth of amoeba at 1: 40, and there was a round precystic form in the culture medium at 1: 60, while saponins could completely inhibit the growth of protozoa at 1: 500 and trophozoite infection in rats at 1: 1000. Both decoction and saponins could effectively inhibit the growth of Entamoeba enterozoa in mice. The low effective dose was 1.0g (crude drug) / kg (equivalent to 250-1max of emetine hydrochloride), but the effect was not obvious when the dose was reduced to 0.3g/kg.

Potentilla frutescens, which is often mistaken as Pulsatilla in the market, also plays a certain role in the test of amoeba histolytica in vitro or in vivo, but it must be in a large dose (3 times that of Pulsatilla). As for other white grass (Rosaceae), White Drum Nail (Caryophyllaceae), Rhizoma Rehmanniae and Asteraceae, which were mistakenly used as pulsatilla, they had no anti-amoeba effect in vivo and in vitro.

2. Anti-Trichomonas vaginalis: in the experiment of anti-Trichomonas vaginalis in vitro, 60% of the extract or water solution could kill Trichomonas vaginalis in 5 minutes. The extract stimulated the vaginal mucosa greatly, but some of the irritation obtained by acetone and ether extraction was small, and it was still effective against Trichomonas. It is also reported that the MIC of pulsatilla powder to kill Trichomonas vaginalis is 2mg/ml.

3. Antibacterial activity: the juice extracted from fresh stems and leaves of Pulsatilla chinensis can inhibit Staphylococcus aureus Pseudomonas aeruginosa in the body (plate digging method) and lose its effect after removing tannin (while breaking the bowl flower-autumn peony still has this effect) The effect on Shigella dysenteriae was poor, but it was also reported that the effect of decoction on Shigella dysenteriae varied according to the concentration of Shigella, and the effect on Shigella was stronger, and the effect on Shigella flexneri, Freund's and Song Shigella was weakened or non-bacteriostatic in turn.

The components of Baitouweng decoction (Pulsatilla chinensis, Cortex Qinpi, Coptis chinensis and Phellodendron Phellodendri) had neither synergistic nor antagonistic effect on Shigella dysenteriae in vitro. Pulsatilla alcohol extract also had some inhibitory effect on Bacillus subtilis and Staphylococcus aureus in test tube, had no inhibitory effect on the growth of Mycobacterium tuberculosis in vitro, and had slight inhibitory effect on influenza virus infection in mice. The effect of Anemonecernua on pathogenic and non-pathogenic fungi in vitro has been studied, and the results show that it has a weak inhibitory effect on a small number of fungi. The antibacterial active ingredient of pulsatilla is anemonin, which has a synergistic effect with streptomycin on the MIC of diphtheria bacilli, staphylococci, streptococci, Escherichia coli, tuberculosis bacillus, etc., between 8 × 10 (- 5)-2 × 10 (- 6), and anemonin.

4. Antiviral effect: pulsatilla water extract can prolong the survival time of PR8 mice infected with influenza virus, and lighten the lung injury slightly.

5. Other effects: it is reported that the ethanol extract of Pulsatilla chinensis has sedative, analgesic and antispasmodic effects. The whole grass of Pulsatilla chinensis has a cardiotonic ingredient, okinalin, which acts slightly like digitalis. Foreign-made pulsatilla Pulsatillanigricans has a sedative effect, and can reduce blood pressure, slow heart rate, enhance cardiac contraction, and improve gastrointestinal movement. Pulsatilla can also inhibit the germination of plant seeds. The anemone saponin A3 contained in it had a certain inhibitory effect on cancer, and the inhibition rate of Pmur388 was 53.7% at 100 μ g / ml.

Clinical application.

1, treatment of protozoal dysentery: adults use pulsatilla rhizome 15-30 grams a day, water decoction into 3 times, 7 days as a course of treatment. For more serious cases, another 30-50 grams were fried into 100 ml liquid for retention enema, once a day. According to the observation of 23 cases, the frequency of stool and red and white mucus decreased significantly after administration, the average negative time of amoeba was 1.4 days, and the ulcer healed rapidly and all cases were cured in an average of 7 days. It is also reported that ten cases were treated with pulsatilla decoction, all of them were cured, the longest treatment time was 9 days, the shortest was 1 day, the average was 2 days. In addition, pulsatilla tissue extract can also be injected intramuscularly once a day, the initial dose is 2 ml, then increase 0.5 ml each time, up to 3.5 ml; after the symptoms disappear, continue to be injected 5-10 times, and then reduced to 1-2 times a week, the whole process is 3 months. Severe and chronic cases were treated with 5-8 ml pulsatilla tissue extract and 60 ml normal saline for rectal perfusion, once a day. Of the 23 cases treated, 19 cases were cured and 4 cases improved, the average time of disappearance of symptoms was 4.4 days, and the average time of stool turning negative was 6.1 days.

2. Treatment of bacillary dysentery: there seems to be little systematic observation on the treatment of bacillary dysentery with single pulsatilla. It has been reported that 123 cases of acute bacillary dysentery or acute paroxysmal type of chronic bacillary dysentery were treated with modified Baitouweng decoction (Pulsatilla chinensis 6, Cortex Phellodendri 3-6, Cortex Qinpi 2-3, Radix Aucklandiae, Radix Glycyrrhizae and Radix Glycyrrhizae) for 5-10 days or 7-15 days as a course of treatment. Treatment results: the cure rate was 78%, which was similar to that of the control group (treated with sulfonamidine). If the curative effect is observed according to the different intestinal lesions, the curative effect of the catarrhal type is higher, the cure rate is 95%, the cure rate of the erosive type is 75%, and the cure rate of the ulcerative type is 56.7%. The course of treatment of erosion and ulcer is 7-15 days, and 10% green tea decoction is used for retention enema at the same time. In the effective cases, the average antipyretic time was 2.01 days, the disappearance time of abdominal pain, acute weight and abdominal tenderness was 6.9 days, the time of secondary application of stool was 10.02 days, the time of stool character returning to normal was 10.1 days, the time of routine stool examination was 9.4 days, and the negative conversion time of stool culture was 4.05 days.

3. Treat the pulsatilla: take 5 taels of Pulsatilla, wash and cut it into inch sections, soak in 2 jin of liquor, seal in the jar, boil several times across water, take it out and put it in a cool place for 2-3 days, then open the jar, fish out Pulsatilla, bottle the wine and seal it. Take it one hour after breakfast and evening, and drink 1-2 cups each time. Generally, 1-2 months is a course of treatment. It is suitable for patients whose pus is clear and dilute and does not shut up for a long time after ulceration. After treatment, more than 10 cases were effective.

4. Treatment of furunculosis and carbuncle: Pulsatilla pulsatilla 2 taels, fried in water, taken for several days. It is still combined with routine local treatment. There is no adverse reaction after taking pulsatilla, and a few patients have the effect of relieving diarrhea after taking it, which is very suitable for patients with solid heat constipation.

10. Plant culture

What is the breeding method of Pulsatilla chinensis, and what is its drug value and efficacy?

Pulsatilla has a rhizome, an oval leaf and a blue-purple calyx. Aliases are Nai he Cao, Powder Milk Grass, White head Grass, Old Grass and so on. Wild plant, which can be cultivated at home, not only has ornamental value, but also is a kind of medicine that you only know. Today, we will take flower friends to understand its breeding method and what its medicinal value and efficacy are.

The culture method of pulsatilla: reproduction:

The method of plant division is often used for reproduction, and it can also be sown and propagated. Ramet should be carried out in autumn, and sowing can be sowed either in spring or in autumn. Because the seeds are small, sowing should be fine, and it is appropriate to sow in pots.

The seeds should be sown immediately after harvest, and a shallow ditch with a distance of 20 cm and a depth of about 1 cm should be opened on the border surface. The seeds should be evenly scattered into the ditch, covered with thin soil, slightly suppressed, covered with straw, germinated at an appropriate temperature of 18-21 degrees, and the soil should be kept moist for 14-21 days. When the height of the seedling is 3mi 5cm, the seedling is fixed according to the plant spacing of 15cm. The growth temperature is 15-18 degrees (daily temperature) and 6-9 degrees (night temperature). The seedlings can bloom in 2 or 3 years.

Main points of cultivation: 1. Land selection and preparation:

It is appropriate to choose sandy loam or clayey loam with good drainage and deep soil layer. Apply base fertilizer or ring fertilizer 2500 kg, turn 25mur30cm deep, rake fine and dry, and make a bed 1.2m wide.

2. Seed propagation:

Direct seeding was sown at the end of March and early April, and a shallow ditch with a distance of 20 cm and a depth of about 1 cm was opened on the border surface. The seeds were evenly scattered into the ditch, covered with thin soil, slightly suppressed, covered with straw and kept moist. When the height of the seedling is 5cm, the seedling should be fixed according to the plant spacing of 15cm.

Seedling raising and transplanting

Pulsatilla delimited shallow trenches with four teeth on the border surface, spread the seeds evenly into the border, covered with a thin layer of fine soil, covered the seeds strictly, slightly suppressed, and covered with straw. After emergence, gradually remove the straw, when the seedling height is about 3 cm, remove the weak and overdense seedlings. Before sprouting in the autumn of the current year or the spring of the following year, transplant according to the row spacing of 20 cm X 15 cm.

3. Field management

When loosening the soil at the seedling stage, shallow ploughing should be done, so as not to damage the root system. After setting the seedlings, apply dilute dung water once, 1500 kg per mu, compost plus calcium superphosphate in autumn, and watering after fertilization. When the flower stem buds, it should be cut off in time to promote root development.

The efficacy and function of Pulsatilla chinensis

Pulsatilla has high medicinal value, which can be seen from the above-mentioned monographs on Materia Medica. According to traditional Chinese medicine, pulsatilla has the effects of clearing heat and detoxification, cooling blood, eyesight, and eliminating encumbrance. There is a poem saying: "White-headed Weng with bitter and warm taste enters the heart meridian and kidney meridian, and febrile disease is the main treatment, and accumulates and accumulates. All the gall tumors can be dispersed, and the epistaxis golden sores can also be leveled. The vulva hernia is cured, it is swollen, and the bald sore can be cured. Abdominal pain, bone disease, toothache, red dysentery can clear the toxicity. The intestinal dirt can be cleaned up, accompanied by the effect of alcohol. "

First, the efficacy of Pulsatilla chinensis

Pulsatilla is the dried root of Ranunculaceae plant Pulsatilla. Pulsatilla is also called Maoguduhua, Old Lady's Flower, and Old male Flower. Pulsatilla has the effects of clearing away heat and detoxification, cooling blood and stopping dysentery, and killing insects. Pulsatilla mainly treats heat-toxic dysentery, epistaxis, blood hemorrhoids, belt, Yin itching, carbuncle, scrofula. Avoid taking pulsatilla with deficiency cold and diarrhea

Second, the function of Pulsatilla chinensis

White head Weng taste bitter, cold; return to the stomach, large intestine meridian, with heat-clearing and detoxification, cooling blood to stop dysentery, dryness and dampness insecticidal efficacy, mainly for the treatment of heat-toxic dysentery, epistaxis, blood hemorrhoids, Yin itching, carbuncle, dysentery.

The function and efficacy of Pulsatilla chinensis has been meritorious for a long time, and it has been clearly recorded in many of our medical books, which explains in detail the functions of Pulsatilla pulsatilla summering foot Yang Ming Meridian, Fu hand Yangming Meridian, releasing energy to dissolve, removing hot and cold blood and so on. Those effective functions and effects are obtained with rich clinical experience and identified by pharmacognosy research.
