At noon on 29 july, the fever of the sun. In the offices of the forestry science and technology extension service in the vanning autonomous district, senior engineers preferred to sit down: “the oil and tea seedlings are not yet stable, and i will look at them again.” he then took the straw hat, climbed the top of the mount of flower fruit and drilled into a shed near the temperature of 40°c。
At first glance, the service station is surrounded by old office buildings; most of the staff members are as black as they prefer to compete, and their hands are rough ... It seems that they do not go anywhere along with “scientific research”。
I'd rather compete in the shed to watch viinen oil and tea grow. Gear
However, the service operates a national base for the cultivation of 1568 acres of forested and wooded species, with a focus on the collection and preservation of selected oil-bearing tea varieties。
Not long ago, the contest ended with an experiment of “innocent” — the marriage of four stable species from the “grass sea” series chosen by the county, 28 excellent monoliths and other species imported from high altitudes. There is only one goal: to produce the best short-coated tea species that are best adapted to the cold weather in the vignel。
On 15 june, he was led by 28 workers to cut the wood and sprouts. Over 40 days, 200,000 seedlings completed their marriage。
Viinen oil and tea growing in the shed
Looks green inside the shed, rising from the sprouts of rice grains to more than 10 centimetres high, and prefers the tight-locked eyebrow sprouts to spread: "it's so competitive!" watch closely, the seedlings glitter a little silver - it was his idea to replace the traditional plume with aluminium chips。
Aluminium tablets are more binding, which greatly increases the efficiency of the bonding; and it is even better to avoid the damage that may be caused by artificial decomposition by the automatic “disconnection” of the aluminium tablets as the lumbers and the bees grow thicker。
A rough measure of the height of the seedlings and a clear increase in confidence in the preferred selection: “as a result of this trend, the survival rate of the viinen short column tea is expected to be more than 90 per cent, and prospects for future production and oil quality are considerable.”
When it comes to oil tea, there must be a place for viinen short pole oil tea。
It does not seem appropriate for common oil and tea varieties to be warm and cold and viinen to develop the oil and tea industry。
In fact, the amount of oil and tea in the district is alarming — it is widely spread across 27 townships in the county, with a total area of 200,000 acres, of which 178,000 acres of wild resources, or 2. 632 million, are highly endowed。
In 1977, prof. Lee yongkang and others, from the university of guizhou school of forestry, discovered and named the viininen oil tea varieties. As the only highland species in the country that is unique to guizhou province, it grows from 1,700 to 2,600 metres above sea level and is cold, drought-resistant and infertile。

Moreover, the viinen short-column tea-dryseeds have a 70 per cent passivity rate, with a 43. 25 per cent export rate, and the extracts are rich in unsaturated fatty acid, of high quality and value added。
How to develop the oil and tea industry? The competition has been wondering。
In 2012, the first exposure to oil tea was to a wild oil tea forest of age, degradation of varieties and low yield
In 2014, observations began to be made and seedlings were selected
In 2021, a major breakthrough was made with the successful identification of four species in the “grass sea” series
In 2023, the central fiscal forestry science and technology extension demonstration project landed and built 1 ton of production capacity/tangue tea seed cooling demonstration line within the service station, and 250 kg production capacity/tien-rich teaseed refining demonstration line to address the issue of oil and tea processing
From 2022 to 2024, 400 acres of demonstration base were planted in the town of fusunsan and the town of fork river, and 60 acres were converted into low-yield forests。
The oil and tea industry was once again the focus of document no. 1 of 2025, and was identified as a priority area for national food security and rural revitalization, with policy support ranging from good breeding, base-building to a full chain of precision processing。
Vegetable oil produced from viinen short-bar oil tea
Against this background, the wiening pitt oil tea offers new opportunities for development。
“it will be almost two years before a good seedling is planted. We will distribute seedlings to farmers free of charge, teach them to grow them, then collect the fruit to extract the oil, and gradually scale up and model the oil and tea industry.”
Tea trees are planted on mount huago and tea oil is extracted from the mount. Vinin's wild oil tea, “deep in the mountains, no one knows about it”, has passed。
