Diantan green pepper grows in the karst area of ​​the Beipanjiang Grand Canyon, because of its low altitude, gas temperature, long sunshine, and small temperature difference. As a result, the green pepper grows and mutates in this place. As a result, the volatile oil (scented oil) of the topping green pepper is higher than the common green pepper, and the flavor is refreshing and alcoholic. In the green pepper is the top product.

Pepper is an indispensable and very common flavoring in Chinese cuisine. It is in the kitchen of every family and is the magician in the kitchen. It is usually grown in the courtyard or on the outer wall, and each household will plant it to wait for the result to dry the fruit and cook it as a pepper. Among the major cuisines in China, Sichuan cuisine is particularly fond of pepper, because its spicy and spicy taste is very suitable for the same taste of Sichuan cuisine. The 2012 first documentary "China on the Tip of the Tongue" has a lot of descriptions on pepper. In the cooking, pepper can eliminate the meat taste and oil of meat, and a kind of clear fragrance and spicy feeling are loved by our people and widely used in cooking. Dingtan pepper is also called Diantan green pepper, belonging to the deciduous shrub or small tree of the genus Rutaceae. It is the first of all kinds of peppers with its large particle size, pure numbness, fragrant smell, green color and long-lasting taste. Rich in Guizhou Province, China. Ecological habits Dingtan green pepper plants are small, with shallow root distribution and strong adaptability. They can make full use of idle land such as barren hills, wasteland, roadsides, landsides, and houses. The mountain built a pepper garden, generally with sufficient light, good drainage, high output and good quality. On the sunny and semi-sunny slopes in the middle and lower part of the hillside, sandy loam or lime soil with gentle soil, terraced ridge, loose soil, deep soil, fertile and well-drained soil is also a good forest land for planting pepper. Hi light, suitable for warm and not too moist and deep soil fertile loam, sandy loam soil, strong germination, cold resistance, drought tolerance, strong disease resistance, long crypt bud life, it is resistant to strong pruning. Anti-drought but not resistant to phlegm, long-term stagnant water can kill pepper saplings. Shape and sensory characteristics First, the pepper tree does not fall in winter, the seasons are evergreen; the second is that the top flower pepper has undergone long-term natural elimination and artificial selection, forming a new variant of green leaf pepper. Compared with the original varieties of bamboo leaves, the leaf axis and leaflets of the leaves are sparsely punctured or smooth and thornless. The umbelliferous panicles are axillary or simultaneously born on the top of the lateral branches. The difference in length is about 2-7cm, and the number of small flowers is more. When the fruit is ripe, the peel is often olive green, and the peel has obvious convex polka-like oil glands. It has oily oysters, is rich in volatile oil, has a strong aroma, and is rich in oil. It has "eat in the mouth, hemp in the mouth." On the top, the heat is on the body but not on the fire but cool in the heart." Distribution and growth environment Diantan pepper is a unique economic plant in Guizhou, Sichuan, Chongqing, Yunnan, Guangxi, and Hunan. It is uniquely scented and tasted by its unique topography, landform, soil and other natural conditions. It is known for its heavy taste and high yield. It has been cultivated for hundreds of years. Because of its characteristics of calcium, drought tolerance, and good soil and water conservation, it has high economic value. It is currently the main soil and water conservation economic tree species in the region. Therefore, scientific and rational development and utilization of these characteristic resources of Dingtanqing will be The organic combination of ecological reconstruction and the construction of the pepper base will be of great significance to alleviate the contradiction between the ecological environment and the huge population pressure. It is of great significance to cultivate and strengthen the competitiveness of the pepper industry and industry, improve the regional ecology and develop the social economy. Origin and development history Dingtan pepper origin: Gengfeng City, Xingyi City, Guizhou Province, Panjiang Town, Dingtan District, called the Gongzhai Group No. 29, the family name is called 冉茂材, since 1990, the seedlings have been gradually cultivated to change the pepper varieties. Later, the entire top area was planted with this variety of pepper. In 1991, Guizhou Fengfeng County was called “the hometown of Chinese peppers”, and the top flower pepper was produced in the Beipan River valley of Zhenfeng County, which is known as “the hometown of Chinese pepper”. After long-term accumulation and development, the small pepper has not only brought significant economic and social benefits, but also brought significant ecological benefits. According to statistics, by 2008, the county's pepper planting area has reached 150,000 mu and the output is 11,000 tons. The output value is 150 million yuan. The per capita net income of a farmer in the top area of ​​the core production area is more than 1,000 yuan, and the per capita income of Yundongwan village is as high as 30,000 yuan.
