Kind of garlic in Datun Village has a history of hundreds of years. It is said that the purple garlic grown here was imported from Japan. Datun Village is located on the north bank of Miyun Reservoir. The soil is mostly sandy, fertile and loose, and the garlic planted has a unique taste. According to reports, the garlic produced here has three characteristics: first, it tastes moist, crisp, juicy and spicy, while other garlic is more spicy; Second, garlic is big, generally six petals, which is two or three grams heavier than ordinary garlic, but some of them are single garlic, which is relatively small; Third, the storage time is long, and it can be stored for nine months at room temperature. The garlic here is a bit strange. It doesn't last long in different places, and the service is not good or long. An old man in the village told reporters that a villager in the village moved to Shunyi and brought garlic seeds, but he couldn't grow a taste here.

Datun Village has a total of 700 mu of farmland, planting garlic 100 mu, with an annual output of 50,000 kilograms of garlic and an income of 750,000 yuan. There are more than 200 families in the village, and almost every family is in kind of garlic. Garlic is planted at the vernal equinox and harvested at the summer solstice. The growth period is 3 months, and only one crop is planted every year. In order to make garlic planting more large-scale and intensive, the garlic planting cooperative was established in the village in early 2006, and now it has become one of the 30 cooperatives with the most development potential in the county, and the characteristic garlic planting has become the leading industry in the village. Fu Dongchun, the village director, told the reporter confidently: "Now our purple garlic is in the certification period of organic food. This year is the last year. After passing the organic certification, the price per kilogram reached 30 yuan, and the output value per mu reached 1 10,000 yuan. "
