The county is located in the slopes of the plateau edge of the Yungui Plateau to the low hills of Guangxi. The terrain increases from the northwest to the southeast. The highest elevation in the county is 1634 meters, the lowest altitude is 375 meters, and the average elevation is 830 meters. It is the lowest latitude county in Guizhou. The color of the hunter tea is light yellow, clear and transparent. It has no stratification for a long time, the smell is fragrant, the quality is pure, and the food is delicious. With a hundred years of traditional production technology, the book Hengheng tea oil has spread all over the country and has become a household edible oil product.

The county is located in the slopes of the plateau edge of the Yungui Plateau to the low hills of Guangxi. The terrain increases from the northwest to the southeast. The highest elevation in the county is 1634 meters, the lowest altitude is 375 meters, and the average elevation is 830 meters. It is the lowest latitude county in Guizhou. The soil has obvious vertical zonal distribution. The red-brown sandy loam formed under special climatic conditions in the Panjiang River valley in the north and south belongs to oily sandy loam. The thickness of soil layer ≥80 cm accounts for more than 60% of the whole area. The average is about 5.4, which is slightly acidic soil, and the soil organic matter content is high, reaching 35.5g/kg or more. The area where the seed oil tree planted is generally below 500 meters above sea level in the county. The low altitude conditions ensure that the Camellia oleifera tree can always grow in a stable high accumulated temperature climate. The Camellia oleifera tree is flourishing and the result rate is high, while the hills and valleys are high. The slope topography is adjacent to the south plate and the north plate of the two rivers. The camellia seed trees are planted according to the terrain. The stepped arrangement provides sufficient sunshine for each tea seed tree, and the water and heat conditions are abundant, so that the oil tea tree can maximize the photosynthesis. It is reflected that the camellia fruit thus presents a large, high oil content. At the same time, the acid sandy soil in the planting area is loose and transparent, and can store water without much water. It conforms to the biological characteristics of the oil tea tree and the water is not enough, which makes the oil tea fruit with low moisture content and high oil content.

The technical requirements for the quality of the book Hengheng tea are as follows: the local traditional varieties such as the “red ball”. Second, the site conditions are within the range of 500 m to 1000 m above sea level, the soil type is red soil or yellow brown soil, the organic matter content is ≥1.0%, the soil pH is 4.5 to 5.4, and the soil layer thickness is 40 cm to 80 cm. Third, planting and harvesting 1. Planting: planted from November to February of the following year, planting density ≤ 2400 plants / hectare. 2. Fourth, processing 1. Processing technology: raw materials → storage → pretreatment → steaming → pressing → filtration → refined oil. 2. (2) Storage: temperature ≤ 20 ° C, storage period ≤ 170 days. (3) steaming and frying: temperature u003c100 ° C, steamed until water ≤ 6%. (4) Pressing: pressing temperature ≤ 100 ° C, oil yield ≤ 25% (5) Filtration: temperature 60 ° C to 70 ° C. V. Quality characteristics 1. Sensory features: oily light brown, clear and transparent, tastes mellow, long time without stratification. 2. Safety and other quality technical requirements: Product safety and other quality technical requirements must comply with relevant national regulations.
