background introduction
The census team I participated in this time is responsible for Puge County, Liangshan Yi Autonomous Prefecture, Sichuan Province, which is the birthplace of the Yi Torch Festival. There are more than 200 kinds of common Chinese herbal medicines such as Cortex Phellodendri, Rhizoma Coptidis, Rhizoma Dioscoreae, Radix Codonopsis, Radix Angelicae Sinensis, Rhizoma Pinelliae, medulla Tetrapanacis, Bulbus Fritillariae Cirrhosae, Herba Lysimachiae, Radix Aconiti, Radix Aconiti Kusnezoffii, Caulis Spatholobi, Eucommiae Cortex and Radix Astragali. Subtropical humid monsoon climate, May-10 is the rainy season.
Before taking part in the census, I thought that the census activity was to go to the market and collect medicines in the mountains. Participating in it, I found that the general survey of traditional Chinese medicine resources is a very hard internal test. Only by relying on a large number of field surveys and sample statistics can I obtain relatively accurate and effective information. Moreover, it is time-consuming and laborious, and it is difficult to produce visible results. A lot of information is only known after field investigation, especially the statistics of wild medicinal plant resources, which requires professional plant classification and identification. High-intensity work and hard conditions in the field also made me respect the three lesbians in the team.
The work content is mainly divided into two parts: field work and indoor work. Field work includes taking samples, collecting specimens, investigating and visiting the Chinese medicine market. The internal manager mainly arranges specimens, arranges and uploads survey data, and writes survey reports. Due to the long participation time, we will introduce the details in stages.
Departure: June 2065438+August-June,1June-June, 17, which is the Dragon Boat Festival holiday. Teacher Lan, who led the team, took into account the strong atmosphere of the Dragon Boat Festival in Puge County. A large number of folk Chinese medicine vendors will gather in the local market and have a good understanding of the local Chinese medicine market. So I booked a direct train to Xichang on the evening of the 8 th. After arriving at Xichang Railway Station, it was already the morning of 17. After several rounds at noon, I arrived at the accommodation in Puge County. After taking a nap, we went to the market for a preliminary inspection in the early afternoon.
Because in the afternoon, the market is no longer lively in the morning, and many vendors have already dismantled their stalls. After several searches, we found that the first vendor we met was a kind old woman.
In the chat with grandma, I learned that the medicinal materials in the shop are collected by myself, and the types of medicines sold have the function of nourishing, expelling wind and removing dampness, and the business is very good.
Our eyes were attracted by the second vendor, who was selling Polygonum multiflorum Thunb.
The third grade wild gastrodia elata is 200/ kg.
Due to time, there are not many vendors in the market, and we are also going to go back to the resource investigation office of the Health Planning Commission to process the medicinal materials we just bought.
Although it is in the rainy season, the sun after the rain hurts people. We found a shady place in the courtyard of the Health Planning Bureau to process Polygonum multiflorum Thunb, which we just bought. Removing sediment and roots, washing, cutting into pieces, drying in the sun, and taking photos and archiving in one go.
Unconsciously, it was seven o'clock in the afternoon, and the clouds in the west gradually turned red. This is what the census team said: the last task today is to double the samples collected in the previous period and check the inhibition. The quality and quantity of preserved leaf specimens are the most direct embodiment of the whole team's work, which requires not only the petals of leaves to be pressed completely, but also to look good. It is very important to turn the paper frequently to ensure the loss of water and prevent mildew.
It's ten o'clock in the evening at this time, but the expedition hasn't had dinner yet. This time is the normal work every day. So we packed up what we needed for tomorrow, had dinner and went back to our apartment. Since we came to our residence at noon to fill the solar water heater in time and went to the market, the female players had only cold water after taking a shower, so we two male players took a cold shower to welcome the arrival of the market research and harvest the next day.
