[Edit this paragraph] Expert explanation

1. Herbal Supplement: Camptotheca grandiflora is an important drug for treating blood pain, and nourishing yin is very effective and self-sufficient. What is the use of a woman's prescription?

2. "Outline": Leilinghua and its roots, sweet and cold, bitter stems and leaves, and blood can remove blood and reduce fire, so it is mainly responsible for the symptoms of lactation bleeding and blood heat and wind.

3. "Herbal Classic": purple storage is a bitter medicine that enters the liver and promotes blood circulation, so the housewife's milk is lingering, and the symptoms are collapse, forehead bottom, blood occlusion and heat, and winning thin; As for raising a fetus, it is by no means suitable for its nature, so it should be used with caution.

4. "Materia Medica": Porphyra is cold, the taste wins first, and it kills after suffering. There is no doubt that they will dissipate heat when they enter the blood. The clouds in Didanxi nourish yin skillfully, and when they arrive in the lake, they enter the blood to reduce the fire, but they are not common. For example, Ying Xiyong thinks that blood is astringent, or according to the so-called "Materia Medica", the forehead is lame and the blood is cloudy? "Rihuazi" cloud cures heat and toxic wind, and covers it, that is, the heat depressed in blood turns into toxic wind. Although sex is the main activity, it must be able to nourish yin and then remove heat and toxic wind, that is, behavior complements it. If you doubt that it can stop bleeding, try to think about why it tastes so salty. Gedo eats salted shellfish and hurts blood. People who are afraid of hurting blood will not be strict about blood. Danxi said he could walk alone when defending, but he didn't assume Qin.

5. "Materia Medica worships Yuan": Purple Cang, recently used as a medicine for menstruation and spermatogenesis. Wan Jian, another in Zhongjing, also uses purple to remove the mark on his forehead. It must not be a product for protecting the fetus. The word "foster fetus" in the Classic is considered as the false ear of abortion.

6. "The Classic Meets the Original": Ling Xue Hua, forehead pain and blood stasis, blood gas tingling, wind sores and sores, all of which are used to dispel evil blood.

7. "Materia Medica Seeking Truth": The fire of mortals lies in blood, which blocks yang, itching, collapse and pain. Everything caused by blood madness and blood heat should be treated with this (Camptotheca grandiflora), which is specially used for purging heat. When the heat dissipates the blood, it will live on its own. It's medicine for lung abscess. It's more useful for you. This gram of pregnancy can be seen, indicating that there is madness in it, and the crazy fetus is safe. It is said that pregnant women avoid taking clothes, fearing that their crazy blood will be gone, and that they will use it indiscriminately after giving birth to him. This is an essential medicine for gynecology, but it should be used to treat ears when it is symptomatic.

8. "Materia Medica Justice": The flower of the sky, Upp said that Shennong, Leigong and Junbo are butchers, and Bian Que tastes bitter and salty, which can dispel blood heat, so it can promote blood circulation and remove blood stasis, and can also cure leukorrhagia. Benjing specializes in treating puerperal diseases of women. Just to the puerperium, yin blood is weak and solitary yang is high. It is best to enter the blood directly, so as to protect the consumed Yuan Yin and capture the floating meteorite flame. It can be seen that the ancient people's treatment of postpartum is mainly to support yin and suppress yang, which is contrary to the vulgar view in the later period. It is counterproductive to use warm tonics and vaginal fluids indiscriminately after delivery. If you treat collapse again, you can only act rashly because of hyperactivity of yang, but you can't bear the collapse yourself. Doesn't mean that blood deficiency can cure collapse. The problem of limping and blood stasis is also due to excessive blood heat, not due to cold, condensation, pain and occlusion.

1. Climate soil: I like warm and humid environment. The requirements for soil are not strict, and both sandy loam and clay loam can grow.

2. Planting:

2. 1. Cutting propagation can be carried out in spring or rainy season, and July and August are more suitable in Beijing. Cut solid and stout branches, each with a length of 10- 16cm, cut them on a sand bed, cover them with glass, and keep sufficient temperature and humidity. Generally, the temperature is 23-28℃, and it can take root 20 days after transplanting, and it can be moved to the field in the next spring, with row spacing of 60cm and plant spacing of 30-40cm. In the warm areas of the south, the new skills of the first year can be cut off in the spring and directly inserted into the ground to take root and survive.

2.2. Layered propagation: In July, the thick vines are pulled to the surface, buried in mounds in sections, with tender buds exposed, the soil kept moist, rooted for about 50 days, and then cut and transplanted. Spring in the south can also be layered.

2.3 Root-splitting propagation: it should be carried out in early spring, that is, the seedlings produced by the root buds near the mother plant should be dug up and planted.

3. Field management: Pay attention to watering, loosening soil and weeding for newly planted seedlings, and reduce 1 fertilizer in mid-May or early June to improve flower yield.

[Edit this paragraph] Cultivation techniques

1. Breeding method. Lingxiao is not easy to bear fruit and get seeds, so it is mainly propagated by cutting and layering. ① Cutting propagation. It is mostly carried out in spring in the south and autumn in the north, and April-May is suitable in the middle and lower reaches of the Yangtze River, with high survival rate. The method is to select strong branches without pests and diseases, cut them into small pieces of 10~ 15cm and insert them into the soil, and they can take root in about 20 days. ② Layered propagation. There are aerial roots on the stems of Lingxiao, and the layering propagation method is relatively simple, which can be carried out in spring, summer and autumn. Cutting and transplanting can be carried out after taking root for about 50 days.

2. Management measures. Early management should pay attention to watering, and late management can be extensive. When the plant grows to a certain extent, it is necessary to set up a scaffold. Appropriate thinning can be carried out before germination every year to remove dead branches and over-dense branches, so that the tree shape is reasonable and conducive to growth. Apply some compound fertilizer and compost before flowering, and carry out proper irrigation to make the plants grow vigorously and bloom intensively. It is advisable to choose plants that have been potted for more than 5 years, keep the trunk short by 30-40cm, trim the roots, keep the main root system, and regenerate new branches after potted. Only 3-5 new shoots are left on the upper part, all the lower parts are cut off and made into umbrellas, and the water and fertilizer are well controlled, so it can be shaped in one year. Build a scaffold and let it climb. After budding in the next summer, the flowers should be thinned in time and applied with liquid fertilizer once, and the flowers will be big and beautiful. Keep it indoors in winter, strictly control watering, and prune it before germination in early spring.

3. Pest control. During the period of high temperature and high humidity, Cinnamomum camphora is vulnerable to aphids, and 40% dimethoate should be sprayed 800-500 times in time for control.

Management points: like trees, like fat, like wet. Early management should pay attention to watering, and late management can be extensive. After spring germination, it is necessary to strengthen water and fertilizer management, carry out appropriate thinning, remove dead branches and over-dense branches, and make the tree shape reasonable and conducive to growth; Generally, liquid fertilizer is applied 1-2 times a month. When the plant grows to a certain extent, it is necessary to set up a supporting rod and scaffolding to let it climb. Apply some compound fertilizer and compost before flowering, and carry out proper irrigation to make the plants grow vigorously and bloom densely. After budding in summer, flowers should be thinned in time and applied with liquid fertilizer once, and the flowers will be big and beautiful. Plants that have been potted for more than 5 years should be selected before germination every year, and the trunk should be kept 30-40cm short. At the same time, the roots should be trimmed, and the main root system should be preserved, and then new branches should be regenerated after potted. Only 3-5 new shoots are left on the upper part, all the lower parts are cut off and made into umbrellas, and the water and fertilizer are well controlled, so it can be shaped in one year.

[Edit this paragraph] Market opportunities

Camptotheca acuminata alias: purple flower, upside-down golden bell and morning glory, which belong to Camptotheca grandiflora or Camptotheca americana. Its nature and taste are cold and sweet. It has the effects of promoting circulation of qi, removing blood stasis, cooling blood and expelling wind, and is mainly used for treating amenorrhea, postpartum blood stasis pain, wind-heat-induced wind-induced pain, itching, wind-induced blood stasis and redness, acne and other symptoms. In recent years, pharmacological research has a certain therapeutic effect on gynecological cancer.

First, the distribution of origin of Camptotheca grandiflora

This variety is a perennial vine with strong adaptability to soil and climate. Therefore, the Yangtze River Basin and North China are the most common. The main producing areas are Linhai, Zhejiang, Huangshan, Anhui and Lianyungang, Jiangsu. Flowers and roots can be used as medicine. Harvest in July-September, and choose sunny days to pick the newly opened flowers and dry them.

Second, the price fluctuated in recent ten years.

As early as 1996, the price of Camptotheca acuminata was between 17 yuan, and the price of Camptotheca acuminata doubled from acquisition to listing through the price increase of medicinal materials acquisition station, which was around 30 yuan. Since then, among many flower varieties, the price of Camptotheca acuminata has been optimistic. By 1997, Lianyungang, Jiangsu received 5 tons of goods, plus 5 tons from other producing areas, which is 10 tons. The acquisition of angelica has reached 30-32 yuan, and the market sales in Bozhou have reached 50 yuan, which is in short supply. In 2000, with the increasing demand, some pharmaceutical companies developed injection products, the consumption increased, and the market soared to 70-80 yuan. 200 1 broke through the 100-yuan mark, and there were not many purchases. Roughly speaking, the seed consumption in the market in 2000 has reached 20 tons. High-priced stimulus, such as Chengnan Town, Lianyungang, Jiangsu Province, is the main producing area of Camptotheca acuminata in China, accounting for 80% of the country's output. Flower farmers use walls and courtyards to set up shelves on hillsides and fields to expand varieties. In 2002, they became the government. In order to increase the income of flower farmers and enhance the brand of Camptotheca acuminata, they declared the Jiangsu Camptotheca acuminata base as a "national protected variety of traditional Chinese medicine". Vigorously develop the planting area of Lingxiao in Jiangsu. The price dropped to 50 yuan in 2003, 40 yuan in 2004 and 20-22 yuan in 2003. The output of Lingxiao has increased by 30 tons. By 2006, the purchase price 15- 16 yuan and the market sales price 18 yuan were the lowest ebb for Ling Xiao to enter the market. However, this is only a temporary phenomenon. Since June 65438+ 10, Camptotheca acuminata has shown a rapid rebound trend. From June to August, Sang Yuan all the way 18 rose to the current 20-2 1 yuan.

Third, the current situation of market consumption and output

Camptotheca acuminata, as a cold flower variety, grows and distributes widely. Why did its price go up all the way in just a few years? The author thinks: First, Camptotheca acuminata is mainly ornamental, although it is distributed in more than a dozen provinces across the country, and most of the flowers are scattered but not collected. June is the harvest time, with the most rain, and most of it can't be harvested. Even if it is collected, it will be abandoned in rainy days. Second, during the period of 1995-2000, Camptotheca acuminata had several markets, all of which were operated by large households with huge profits and low prices. In 2000, the number of business households grew from a few to dozens, and the sales road was broadened. From 17 specialized markets of Chinese herbal medicines to pharmaceutical factories, drug-using units and decoction pieces factories, consumption has increased. The annual sales volume of Bozhou market is 15 tons, Anguo 8 tons, Lianqiao 5 tons, Chengdu 3 tons, Guangzhou Qingping 2 tons, Yulin 2 tons, An 2 tons, Yuzhou 1 ton, and other * * * consumption is about 40 tons.

Fourth, the development situation facing the main producing areas.

With the rise and fall of Camptotheca acuminata for ten years, it is the high price of drug farmers that stimulates planting, management and harvest, which makes the output soar. In the past ten years, the yield of this variety has increased 6 times compared with 200 1, and the price has decreased 5 times. Recently, the author visited some flower farmers and large planters on the market trend of Camptotheca acuminata and discussed with them. As a unique port city, Camptotheca acuminata made a detailed analysis and expressed its own views.

(1) Chengnan Town has a long history of cultivating this variety, and flower farmers have certain experience in planting, management and processing. Camphor Camphor Camptotheca acuminata has no pests and diseases in the whole flowering period of three years, and can achieve no pesticide residue, forming a pollution-free green Chinese herbal medicine.

(2) Extra branches must be cut off from harvest to autumn, which is beneficial to ventilation and nutrient balance in the coming year to increase yield.

(3) In 2006, Lianyungang will expand its urban development and list Chengnan Town as an economic development zone. Through urban construction, a large part will be destroyed, resulting in the reduction of camphor resources.

(4) Lianyungang is an open port city. High working hours and low drug prices will affect the picking of camphor.

Five, after the potential analysis

Flower farmers can collect 3-4 Jin of dry goods every day, which is about 50-60 yuan's income. They cut mountains and build roads at a cost of 60-80 yuan per person per day. Some people think that picking flowers is not as good as working, so that the varieties will die. After harvesting, the quality of cool flowers is also very low in rainy days.

This variety is mainly produced in Chengnan Town, Donglei Village of Yuntai Township and Yuntai Forest Farm. Some people are disheartened and begin to uproot camphor trees, which will be a fatal blow to camphor trees. The output of Lianyungang this year is 10 tons, plus 5 tons from other producing areas, which is far from the consumption of 40 tons. Because this variety belongs to the third category, it has not attracted the attention of speculators, resulting in a strong upward trend of materials and a deviation between supply and demand. A few years ago, it was not taken seriously, and it became a best-selling variety in the past few years. As far as the sales situation this year is concerned, the market will exceed 40 tons. Compared with the output of 15 tons, it will undoubtedly give Lingxiaohua a golden opportunity!

In view of the above causal relationship, there will be a big gap between supply and demand of Camptotheca acuminata, and its price will still be popular in the future.
