Where is the origin of walnuts?

1. Walnut is native to southeastern Europe and western and southern Asia. Zhang Qian was introduced into the Central Plains from this area. In the international market, walnut is one of the four dried fruits, and the other three are almonds, cashews and hazelnuts. Walnut is highly valued in Europe and America. Now it is also made into chocolate candy for friends and relatives. And in the local area, we have the same custom of eating jiaozi and moon cakes as China. Walnut has round fruit shape, shallow shell, white core, paper-thin shell and oil content as high as 70%. Enjoy a very good reputation locally.

2. The walnut producing areas in China are Heilongjiang in the north, Yunnan and Guizhou in the south, Xinjiang in the west and Shandong and Liaoning in the east. Among them, the quality of Wan Wen walnut in Beijing, Tianjin and Hebei is the most outstanding, and it is also the origin of traditional fine varieties. Climate and environment are also conducive to the planting and growth of Wan Wen walnut.

3. Northwest China, including Shanxi, Shaanxi, Gansu, Ningxia and Xinjiang. Shaanxi Qinling mainly produces autumn walnuts such as lanterns, which are big, full in shape and full of burrs. The output is also high. Other places in Shaanxi also produce official hats and other varieties, which are too big, and the shape and cortex are quite different from those in Beijing and other places. There are also wild pecans in some mountainous areas of Xinjiang, which belong to autumn walnut varieties. Heilongjiang, Jilin and Liaoning mainly produce autumn walnuts. In Fenyang, Xiaoyi and other places in Shanxi Province, walnuts with thin skin, full kernel and tender meat are being produced.
