Beans are useful, called green oil
On 5 august, open-screen journalists visited the institute of economic crops of the yunnan academy of agricultural sciences, where they interviewed li wengchang, a researcher specializing in research and the promotion of ricin. And he said, "when i was a kid, i was really fond of ricin. At that time, the country was recycled in large quantities. After collecting the seed, the villagers handed it over to the sales agency.”

In the early 1980s, the yunnan academy of agricultural sciences began research work on ricin. Since 1995, li wengchang has been at the forefront of lymphatic science. He said: “it was only in the early years that the results of the studies were slowly increasing when the conditions were premature and technological accumulation was taking place.” at present, he and his team have completed and registered 15 new varieties of thiram, of which thiram 2, tha, tha, tha, and tha,1 are more regional in character。
Yunnan, the country's main breeding ground for ricin seeds, is a leading national leader in quality resource innovation and the selection of new varieties, and is using new ricin varieties cultivated in yunnan in sichuan, guizhou and guangxi。

In the laboratory, li wengchang found a few bags of seed seed from a row of shelves. In appearance, the ricin seed is like a small white bean in a coloured dress. Why, then, is a small seed of ricin classified as strategic goods by some countries
"the ricin seeds are also known as `green oil'." li wengchang said that oil-manufactured products could almost all be obtained through fissure of ricin oil, and that their quality and performance were better in all respects。

The ricin, which belongs to the cormorant herbs plant, has a special physico-physic properties of non-condensation, high temperature 400oc and non-combustion at below zero, and is therefore widely used in important industries such as aviation, machinery and chemical industries. In recent years, the application of ricin oil as a chemical, energy and high molecular bio-based material has been very active, cracking 175 chemical derivatives for oil development and a series of 2000 products。


Extension to more than a dozen countries to provide stable raw materials for domestic industrial development
The ricin is highly adaptable, growing up below 2,000 metres above sea level and growing even less fertile land. My country's ricin seed production reached 299,000 tons in 2011, and since 2012 the area under ricin cultivation has been gradually reduced to 52,000 tons in 2015. Cultivated in guangxi, guizhou, yunnan, sichuan, etc., the country is small. In yunnan province, the area under cultivation is around 10,000 acres per year, mainly in wenshan, dying, jade creek, red river, etc。
Starting in 1998, researchers from the yunnan academy of agricultural sciences began promoting demonstration cultivation of ricin in south-east asian countries. Agricultural technologists serve the domestic industry needs and work with large enterprises abroad to bring new varieties and technologies to countries such as myanmar, cambodia and laos for demonstration planting and technology extension。

Li wengchang said it was difficult to start with. It is more productive than traditional cash crops such as sesame, peanuts, soybeans and maize that farmers are willing to grow. “when local firms and farmers see the benefits, local firms do extensive extension
Since 2014, li wengchang and his colleagues, in their capacity as international science and technology attachés, have been building a country along the way to demonstrate the promotion of ricin cultivation. To date, he and his colleagues have extended ricin to 12 countries, including myanmar, cambodia, laos, the philippines, sri lanka, indonesia, ethiopia, ghana and uganda. In parallel with off-shore demonstration promotion, targeting domestic and international market demand, domestic lead firms are organized to recover all of the seeds planted。

According to li wengchang, 95 per cent of our ricin seeds are imported from india, and the import channel is relatively single, mainly from india. There is a risk of a single source of goods, which is not conducive to the development of relevant domestic industries. The expansion of cultivation in 12 countries has resulted in the expansion of supply channels and the availability of ricin seeds. In 2020, around 20,000 tons of ricin seeds were imported from myanmar alone。
Through new varieties, new technologies, “go out” and “in” product materials, yunnan samples were provided for agricultural “go out”。
Agricultural technology is going out. There's a lot of human exchange
After decades of cultivation, li wengchang and his colleagues used new varieties and technologies to promote agricultural development in yunnan and the “across the road” to build the country, promoting human interaction and economic cooperation。
The greater mekong subregion cooperation group for agricultural science and technology exchange, established by the academy of agricultural sciences of itoyunnan province and the countries of the comun mekong region, established a 500-acre china-myanmar economic crops overseas science and technology demonstration park in mandalay, myanmar, and a science and technology innovation centre for south and south-east asia specialized cash crops (less, red flowers) to promote seeding and demonstration of specialty cash crops in south and south-east asia。

Training was provided to 1306 national scientists and industrial development cadres through various training courses at home and abroad。
In cooperation with domestic and foreign enterprises, the promotion of ricin cultivation has been demonstrated, with local growers repurchased by chinese enterprises and farmers ' marketing problems resolved. Li wengchang said it was found that farmers in some plain areas of myanmar also grow ricin because the ricin is thicker and can be used as fuel for their lives after the harvest. The expansion of new varieties and technologies has led to higher incomes for local farmers and improved the lives of the local population。

Yunnan is connected to the waters of the mountains of south asia and south-east asia and is a human being. In the 11 years since the inception of the one way initiative, yunnan has become more prominent in its important link to the south-west and in deepening china's interaction with south and south-east asian countries. It is the numerous agricultural technologists like li wengchang who “go out”, and yunnan and the “across the road” have become more frequent and more friendly in the field of agriculture。
