The annual birch plant of the genus Bromegrass, which has the characteristics of short growth period, drought resistance, resistance to infertility, and strong adaptability. As one of the traditional crops of Dingbian, Dingbian buckwheat has a long history of planting, and it is known as the “hometown of buckwheat”. Dingbian buckwheat is famous for its large grain, thin and thin skin, high powder yield, nutrient-rich and medicinal value.

Buckwheat, rich in nutrients, contains buckwheat, rutin, niacin, linoleic acid and a variety of vitamins and trace elements, known as the "king of hundred valleys." In the "Compendium of Materia Medica", it is described as follows: "The stomach, the stomach, the spirit, the spirit, the five organs can be refined. For meals, the food is poisonous, very good." "The south of the city is covered with snow, the wilderness family Buckwheat. The frost and the convergence are less at home, and the bread bait is not worried about this winter." Song Dynasty poet Lu You once had such a good harvest in the poem. To this day, this joy continues to be on the fixed side of the land known as the "hometown of buckwheat". Every year in the late summer and early autumn, large buckwheat flowers spread across the mountains, with aromas and unique charm. Dingbian County is one of the four major buckwheat producing areas in China and the largest county in the production of safflower buckwheat in the country. It is located in the core area of ​​the Shaanxi-Gansu-Ningxia safflower sweet-smelling area, and maintains a scale of more than 500,000 mu of buckwheat planting. When it comes to Dingbian buckwheat, the slogan "Dingbian buckwheat is good - Dingzhi" is already famous. On November 24th, the reporter came to Dingzhiyi Agricultural Technology Co., Ltd. to explore its unique charm. Provenance protection – showing the true color of safflower buckwheat Dingbian is recognized as one of the origins of the world safflower buckwheat. Safflower buckwheat is a unique "signature" variety here. "For a period of time, the buckwheat varieties of Dingbian are disordered, the safflower buckwheat and white buckwheat are mixed, the purity of safflower buckwheat is degraded, and the buckwheat granules produced are small and round, which is difficult to adapt to large-scale mechanical processing." Dingzhiyi Agricultural Technology Co., Ltd. Manager Han Yongfei talked about the embarrassing situation of Dingbian safflower buckwheat. "To build a good safflower buckwheat brand and improve commercialization, we must explore a species and purity of the local safflower buckwheat variety." To promote the excellent varieties of safflower buckwheat." Therefore, the company actively cooperated with the Agricultural Research Institute of the Chinese Academy of Agricultural Sciences, Northwest Au0026F University, and the experts of the China Small Grain Research Center, such as Professor Chai Yan, and Dingbian County Science and Technology. With the help of the bureau and the agricultural technology center, the company's cooperatives have opened more than 2,000 acres of buckwheat cereal planting bases in Jishan, Baiwanzi, Youfangzhuang, Yangjing and other mountainous areas, including more than 200 acres of safflower buckwheat original variety protection base. It is responsible for the protection, purification and rejuvenation of the provenance of safflower buckwheat varieties, effectively demonstrating and promoting the excellent varieties of safflower buckwheat Safflower buckwheat is full of "natural colors." Therefore, the safflower buckwheat produced by Dingzhi is rich in grain, brown in color, thin in thin skin and high in powder yield, which is favored by the market. The new use of ancient law - the inheritance of stone milled buckwheat noodles "People who have eaten our soba noodles know that our soba noodles are different in taste and nutritional value, with the nutrition of coarse grains. The taste of fine grains '." Han Yongfei said confidently. Originally, the use of traditional stone grinding process to process buckwheat is the "secret weapon" of the soba noodles. “Because buckwheat is not resistant to high temperatures, low-speed processing with stone grinding can minimize the original nutritional value of buckwheat. The content of carotene and vitamin E is 18 times that of steel milled flour, but it has not been possible to process buckwheat with stone grinding. Mass production." Han Yongfei said. To this end, it is necessary to use the ancient method and combine the original stone mill with the modern electric machinery brake, and innovatively transform the traditional “驴拉磨” into “electric belt grinding (group)”, which not only avoids the tradition. The health problems brought about by “驴拉磨” have preserved the nutritional value of soba noodles, and at the same time realized the quantitative production of stone-boiled soba noodles, achieving the “three bests”. At the 20th and 21st Yangling Agricultural High-level Conference, Dingshi squeezing buckwheat flour was awarded the “Post-Golden Award” and the “Post-Special Award”, and was selected into the “2015 National Famous and Excellent New Agricultural Products Catalogue” of the Ministry of Agriculture. Won the title of “Top Ten Golden Gate Agricultural Products of Shaanxi Province” in 2016.
