When the reporter saw Cao Yunwei, the weather was very good and there was no wind. He and his wife Wang Bufen are busy in the field weeding the lanterns. This is much more profitable than planting crops such as corn and rapeseed. The income from the first cut in September was about 5000 yuan per mu, and we will make the second cut next, "said Cao Yunwei. This is a standardized planting base for Dengzhan flowers located in Shangxinmin Village, Luxi County, Honghe Hani and Yi Autonomous Prefecture, Yunnan Province. Not long after the Xiaoxue solar term passed, I saw clusters of green lanterns growing happily. A few pink purple flowers are elegant and fresh, swaying in the wind. Locals say that when the lanterns are in full bloom, millions of pink and purple flowers are squeezed together to form a magnificent sea of flowers, and the scene is incredibly beautiful. Dengzhan Hua, also known as Dengzhan Xixin, is named after its flowers resembling lanterns and roots resembling Xixin, and is known as the "spiritual grass of southern Yunnan". Dengzhan Hua was first clearly recorded in the book "Dian Nan Ben Cao" written by the Ming Dynasty medical expert Lan Mao. It is an annual herbaceous plant of the Asteraceae family, mainly distributed in the southwestern region of China. Yunnan Dengzhan Hua has the richest medicinal resources, accounting for 95% of the total national resources, and has been protected by the national geographical product label. A healing flower is most afraid of a stroke. A small lantern flower, despite its fragile appearance, has a good set of treatments for stroke. Chen Chaoli, Vice President of Lijiang Traditional Chinese Medicine Hospital in Yunnan Province, introduced that Dianzhan flower has a cold, slightly bitter, sweet, warm and spicy nature, and has the effects of dispelling wind and dispelling cold, promoting blood circulation and unblocking meridians, anti-inflammatory and pain relieving. It is a classic ethnic medicinal herb with a long history of use in the treatment of stroke and stroke sequelae. The Dai, Yi, Miao, Bai, Lisu and other ethnic groups in Yunnan have recorded the use of lantern flowers to treat stroke and hemiplegia. For example, in the Dai medicine book "Apita Ma Jiegan Bi", it is mentioned that lamprews can treat rheumatism, stroke hemiplegia, dementia, colds and coughs, toothache, headache, dizziness, and so on. Modern pharmacological research has shown that the total flavonoids, breviscapine, and caffeoyl compounds in Erigeron brevifolia are considered the main active ingredients and have significant therapeutic effects on diseases such as cerebral hemiplegia, coronary heart disease, cerebral thrombosis, cerebral hemorrhage, cerebral embolism, and microcirculation disorders caused by cardiovascular and cerebrovascular diseases. They have been included in previous editions of the Chinese Pharmacopoeia. The Luxi region of Yunnan Province is rich in the production of lampshades. Throughout history, the local people have had the habit of consuming lanterns and flowers. According to locals, our ancestors often used wild lantern flowers to stir fry eggs or stew eggs, and sometimes boiled them directly into soup and applied it to the eyes. For the convenience of use, local people transplant wild lantern flowers to their homes or courtyards, so that they can be brewed and consumed as a substitute for tea at any time. In 1969, the Yunnan Institute of Materia Medica sent researchers to collect traditional Chinese medicine formulas from the public. A 90 year old Miao traditional Chinese medicine practitioner from Qiubei County, Wenshan Zhuang and Miao Autonomous Prefecture, offered a prescription: stewed eggs with lamplighter flowers can be used to treat cerebral hemiplegia. Next, clinical trials were conducted by Yunnan First People's Hospital and other units, and it was found that the extract of Scutellaria baicalensis had significant therapeutic effects on diseases such as cerebral hemiplegia caused by cardiovascular and cerebrovascular diseases. From then on, Dengzhanhua embarked on the fast lane of development. Sun Handong, an academician of the CAS Member, has been engaged in the basic and applied research of Erigeron breviscapus for decades. In his view, with the development of social economy, the spectrum of diseases is also constantly changing. Among them, chronic diseases and sub-health populations represented by cardiovascular and cerebrovascular diseases are becoming major factors affecting the health of the people. From past clinical application experience, it can be seen that Scutellaria baicalensis has a unique role in the prevention and treatment of cardiovascular and cerebrovascular diseases. After years of research, medical institutions, research institutions, and leading enterprises have developed a series of drugs based on the extract of Scutellaria baicalensis, including Scutellaria baicalensis tablets, Scutellaria baicalensis soft capsules, Scutellaria baicalensis capsules, Scutellaria baicalensis Shengmai capsules, Scutellaria baicalensis injection, Scutellaria baicalensis injection, and Scutellaria baicalensis for injection. At present, there are 40 types of drugs related to Dengzhanhua on the market, of which more than 90% are used to treat cardiovascular and cerebrovascular diseases. Experts said that the traditional Chinese patent medicines and simple preparations of Erigeron breviscapus has clear efficacy components, clear mechanism of action, multi-component and multi target synergy, which will emerge in the future, especially in the prevention of disease, chronic disease management and the prevention and treatment of Alzheimer's disease. A flower that people love for wealth. Cao Yunwei only started planting the lantern flower in May this year. I have heard of it before, but I dare not plant it. After receiving technical support from Yunnan Zesheng Biotechnology Co., Ltd., Cao Yunwei finally got involved in the cultivation of lantern flowers. We just need to plant according to the company's standards and requirements. They provide a series of guarantee measures from planting technology, fertilization guidance to procurement. It's like they hired us, "Cao Yunwei said. As the Deputy General Manager of Yunnan Zesheng Biotechnology Co., Ltd., he has been struggling in the fields for more than ten years. The red part of this plant is caused by frost. It snowed in Luxi a few days ago, "said Guan Dejun. This high-frequency harvesting mode is like cutting chives. If not harvested in a timely manner, the growth of the lantern flowers will quickly reach a peak, and then enter a decline period, and the effective ingredients contained will also decrease accordingly. Therefore, planting technicians have extremely strict control over the harvesting period and must ensure that harvesting is carried out within 15 days of the optimal harvesting period. At present, Yunnan has established the largest scale and most mature standardized cultivation and processing technology for lantern flowers in China. The planting area of lantern flowers in Honghe and Dali accounts for over 80% of the total area in the province. Among them, Honghe has been identified as the most suitable planting area for lantern flowers due to its high altitude, sufficient sunlight, large temperature difference between day and night, and high-quality air and soil conditions. In 2009, the national standard "Geographical Indication Product Honghe Lamplighter" was promulgated and implemented. The content of Lamplighter B in artificially cultivated Honghe Lamplighter was generally between 2.20% and 2.78%, which was nearly 10 times higher than the standard of 0.3% in the Pharmacopoeia of the People's Republic of China. Red River lantern flowers are superior to those from other production areas in terms of yield, appearance, and internal quality Lin Yanhai, the Quality Director of Yunnan Biovalley Pharmaceutical Co., Ltd., said that according to measurements, the effective ingredients of Honghe Lamplighter are 37% to 50% higher than those in other regions. This is inseparable from the special climatic conditions of Honghe - the angle of solar projection is large and the amplitude of change is small; During the day, there is sufficient sunlight, high temperature, strong photosynthesis, and accumulation of organic matter; The low temperature at night and low consumption of organic matter are conducive to the synthesis and accumulation of nutrients in Lampyridis. In addition, the unique content of various elements in the soil makes Honghe an authentic medicinal area for Lampyridis. With the advancement of technology, the planting season of lantern flowers is no longer limited to the traditional spring and autumn seasons, but can be flexibly adjusted according to demand. For example, some places choose to sow in winter and harvest in April or May of the following year. Xu Yunbo, Deputy General Manager of Yunnan Zesheng Biotechnology Co., Ltd., has been working in the lantern industry for nearly 15 years. She said that the use of a "company+base+farmers" model to promote the planting of lantern flowers requires a large number of workers from land preparation, sowing and seedling cultivation, weeding, fertilization to picking and harvesting, effectively solving the needs of local villagers to work nearby and increasing the income of local residents. From 2018 to 2023, the company has promoted the planting of 20000 mu of Lamplighter in 6 towns and villages including Zhongxin Town, Jinma Town, and Baishui Town in Luxi County, with an average output value of 15000 yuan per mu, achieving an agricultural output value of about 300 million yuan for Lamplighter. In Shigangchong Village, Jinma Town, Luxi County, Yang Laosan has been planting lanterns for four to five years. The yield per mu is getting higher and higher, the quality of medicinal materials is getting better and better, and the output value per mu has also increased from 7000 to over 15000 yuan at the beginning, "he said. His family has also undergone many gratifying changes - the old house has been renovated and rebuilt, and he has bought two sets of commercial housing in Luxi County. Now their two sons have returned to their hometown after graduating from college and planted lanterns with him. With the help of industrial flower technology, it wandered around the lantern planting base for a while, and the soles and uppers of its shoes turned red. The red soil land in Yunnan is truly worthy of its reputation. This kind of land is not only rich in various minerals, but also very loose and not easily compacted. Preventing soil compaction is one of the issues that needs special attention during the planting process of lantern flowers. In Cao Yunwei's field, there is a pipe standing a few meters away. This is called standing pipe, "Guan Dejun said." In the past, sprinkler irrigation facilities laid in the ground could easily cause soil compaction when sprayed and dropped on the ground. This standing sprinkler irrigation system sprays water like light rain and mist, moistening the soil silently and gradually penetrating into the soil. "" This can ensure the respiration of the roots of the lantern flowers, "Guan Dejun further explained." When the respiration of the roots is strong, oxygen is sufficient, fertilizers are absorbed well, resistance is strong, the disease is reduced, and pesticide residues are better controlled, forming a virtuous cycle. "The planting technology of lantern flowers has always been on the road of technological innovation and technological achievement transformation, and the effective ingredient content of artificial planting is wild resources. More than three times. There are abundant germplasm sources, including 14 germplasm sources such as Zesheng, Dianling, and Airijie that have obtained new variety certificates. At present, Honghe Lamplighter has achieved high-level standardized planting in Luxi and other places. 80% of the raw materials for lanterns on the market come from standardized planting bases, ensuring reliable sources and quality of the materials. At the same time, the "direct seeding film mulching cultivation model" was popularized and utilized. The incidence rate of root rot disease was reduced from 70% to less than 5%, and the coverage rate of improved varieties was more than 80%. It was the first variety to realize the improvement of traditional Chinese medicine in Yunnan Province. With quality assurance, a flower can create an industry. In 2023, the sales revenue of drugs and preparations made from Lamplighter flowers in China will reach about 6 billion yuan, of which the sales revenue of Yunnan Lamplighter flower series products will be nearly 2 billion yuan. In recent years, major universities, research institutes, and leading enterprises in Yunnan Province have joined forces to focus on the breeding, standardized planting techniques, pharmacological efficacy evaluation, effective ingredient extraction, processing technology, and product development of Scutellaria baicalensis. Innovative achievements continue to emerge. We have been focusing on lantern flowers for over 20 years, adhering to the principle of using technology to support industrial development and focusing on realizing medical value Hu Jianhui, General Manager of Yunnan Biovalley Pharmaceutical Co., Ltd., said that the company has been committed to the research, development, product production, and sales of Lamplighter. It has achieved a full lifecycle layout in the fields of primary prevention, secondary prevention, and acute phase treatment, and has completed evidence-based medicine research on Lamplighter oral preparations in the rehabilitation and secondary prevention of cardiovascular and cerebrovascular diseases. And the starting point and ending point of all of this are in the field of lanterns and flowers. Dengzhan Hua is used to cure diseases and save lives, "said Cao Yunwei." When we grow it, we must first ensure its quality and avoid various problems such as pesticide residues, so that others can use it with confidence
