"look at this fruit, the size of the zoo species can be up to five centimetres and the weight of a single fruit is over 60 grams. That's the strength of a good breed." early in the morning of 17 october, in 200 acres of the oil tea forest of the specialized co-operative for oil and tea cultivation, professor tan xiaofeng of the university of forestry and technology of south-central china fell down and pulled the leaves to show the surrounding forest farmers with branch-covered tea fruit, with the fingertips of the morning dew and the oily light of the fruit。
On the same day, the hunan forest society organized a team of experts from hunan university and the hunan academy of forestry sciences to conduct a site survey of the results of the “technology innovation and application for high-inputed and low-input forests” in order to test good seed techniques in the field and share the joy of harvests face to face with foresters。

In the event of a disaster, 1432 kg of acreage and only 150 to 250 kg of common varieties were produced
This 200-acre test site contains key answers to the oil and tea industry。
The oil tea planted in 2013 was sprung, and in 2021 and 2023, the new head operation was carried out twice, with the use of a pedigree to switch tree heights to a new technology, and the marriage of the three great species of "face" "face" and "face" "face" and "face". The forest area, which has a standardized layout of about 80 acres, with a distance of 2. 8 metres and a distance of 3 metres, has demonstrated a strong productive potential, despite successive natural disasters, three months of drought following its succession in 2022 and the onset of ice attacks in early 2024。

“it is the harshest and most realistic test for this production to be measured in 10 series of fruits per species of sampled plots and to be recounted in the acreage by a single fruit. According to li zai, an associate professor at the south central forestry university of science and technology, this methodology is in line with the criteria for evaluating scientific and technological results. “we need to measure the most accurate data so that farmers and foresters can better choose to promote oil tea varieties”
The results of the final site survey show that four years later, the “gold” varieties of tea produced 143. 2. 8 kg of fruit per acre, calculated to produce about 75 kg of tea oil per acre, well above the 150 to 250 kg per acre per acre per acre per acre per acre, and confirmed the superiority of the “golder” “golder” varieties。

Technology activates low-yield mountain forests, increasing the efficiency of old woodlands by three to five times
The core technology identified this time is the key to overcoming the poor production of our oil and tea. The traditional tea acres often hovered between 8 and 13 kg, while the xinjiang test site, using high-tech replacement techniques, was able to cross "the year of matrimony, two-year broods, four-year production" by marrying good ears on old trees, preserving the nutrient absorption advantages of mature roots and injecting good seed genes。
The sanhua oil and tea seed developed by the tan xiaofeng team gives this technology a triple advantage: the weight of the fruit is three times that of the common species, the tree is reduced to 3 to 4 metres for extraction and the cost of harvesting is reduced from $1 to 1. 2 to 0. 4 to 0. 5 per kilogram。

" this is not a simple substitution of varieties, but a precise combination of resistance and abundance. “tang xiaofeng stressed that the new sing test base remained stable under the double pressure of drought and ice, confirming the maturity of the technological system。
The anti-resilient nature of sanhua oil and tea is particularly valuable for hunan. In hunan province, where more than 333,000 hectares are cultivated (municipalities and districts), there is an urgent need for low-yielding forest rehabilitation, and high-tech replacements can increase the efficiency of old woodlands by three to five times。

Turn low-yielding forests into "green banks" to boost the incomes of tens of thousands of farmers
As the first province of the country, hunan promoted industrial upgrading through a three-year operation, with a combined production of over 440,000 tons of tea and oil in 2024, amounting to $94. 3 billion, leading to an increase of 1. 1 million farmers. The good seed production practices of shinsheng county are more closely aligned with the transformation of low-yield forests into "green banks" through the "cooperative+base+technology" model. At present, this path has been extended to include south china, guiyang, etc., leading to employment gains for tens of thousands of farmers。
" a pot of oil and tea can end up for more than 60 years, and good technology can sustain the forest. "the head of the pear garden oil and tea industry professional co-operative, yang yuu-yo, made a debt: the annual revenue per acre after the conversion of the low-yielding forest can be 3250 to 4550 yuan, which is four to six times higher than the traditional varieties, based on tea oil from the sanhua acre at 50 to 70 kg and 65 yuan per kg。
The more far-reaching value lies in the prospects for technology diffusion, where there are over 60 million acres of oil and tea forests in the country, and where half of these technologies are adapted, the industrial potential will grow geometrically。
The site of this new wave is not only a collection of production data, but also a living case of technological empowerment of rural renewal. With the spread of key technologies, such as high-tech switching, hunan's millions of acres of oil and tea forest will be transformed from "ecological barriers" to "rich engines" and a living response to "green water and green mountains are silver mountains"。
