Lingshui walnut

When it comes to Mentougou, Beijing, it is one of the important export bases of walnuts in China. When it comes to Lingshui Walnut, people will stretch out their thumbs and pay tribute: it is big, thin-skinned, full of kernels and high in oil content. In recent years, a thousand acres of walnut base has been built. Walnut was once called "Walnut" or "Qiangtao". The country of origin is west Asia and southern Europe. Zhang Qian, the envoy of Emperor Wu of the Han Dynasty, went to the Western Regions and introduced walnuts to China after returning home. Zhang Hua, a Jin native, wrote in his Natural History: "Zhang Qian brought back the Western Regions and got walnut seeds, so it was named after walnut." In the Ming Dynasty, Li Shizhen's Compendium of Materia Medica also described as follows: "Walnut, this fruit tree comes from Hu Qiang. In the Han Dynasty, Zhang Qian brought back the seeds from the western regions, which were planted in the middle of Qin and gradually spread to the east. " It is said that in 319 AD, the general Hu Renshile occupied the Central Plains and established the post-Zhao Dynasty. Because of the taboo of "Hu", he changed the word "walnut" to "walnut", which has been inherited ever since. Walnut is a deciduous tree, monoecious, with spherical fruit and rich nutrition. It can not only be eaten, pressed oil, but also used as medicine. According to the analysis of Health Research Institute of China Academy of Medical Sciences, each walnut in Jingxi is more than 10g, and the oil yield is 45-65%. Walnut kernel contains 15.4g of protein, 63g of fat, 10.7g of carbohydrate, 108mg of calcium, 329mg of phosphorus, 3.2mg of iron, 0.17mg of carotene, 10.32mg of vitamin B, 20.11mg of nicotinic acid. In particular, the fat content accounts for the first place in dried fruits. After walnut kernel is pressed, the residue can be used as walnut sauce; Dry fried or fried walnut kernel is a special snack; Qingque brand walnut milk is unique and popular. In addition, walnut is also a good medicinal diet for getting rid of diseases and keeping fit, which has the effects of keeping fit, enriching blood, strengthening brain, moistening lung and benefiting stomach. Speaking of walnuts, there are three things that Mentougou should mention. First, Yanjiatai Village has a 300-year-old walnut tree with a maximum annual output of more than 1,000 kilograms, which is known as the "King of Walnuts" in the suburbs of Beijing. Second, the "Dongling No.6" walnut cultivated with the help of the scientific research department has a thin skin and exposed nuts, and was rated as the first superior line of walnuts in China; Thirdly, on June 29, 1959, the Central Ministry of Agriculture organized a field meeting on the prevention and control of walnut black in the north, at which Malan Village performed the method of fumigating with aerosol. Nevertheless, Jingxi Walnut is the most famous walnut in Lingshui: its skin is smooth, the ditch is shallow, the fragrance is strong, the skin is thin, soft and easy to peel, and the kernel yield is high. Therefore, no matter which village produces it, as long as it is a good product, it is called "Lingshui Walnut". There is a folk song saying: Tell you, tell him that Lingshui walnuts are of great use. Edible and medicinal for oil extraction, the empty shell is also used as a thorn Lala.
