According to ancient books such as the Natural History, Xinjiang has a history of cultivating walnuts for more than 2000 years. Chinese walnut kernels here have many varieties and good quality. There are more than ten kinds of fruit types, including small fruit type, large fruit type, round fruit type, pointed fruit type, elliptical type and thin shell type. Each variety has different characteristics. For example, the famous thin shell walnut, whose shell is as thin as paper, can almost see the shape of the nut through the sunlight. Just use your hand to gently pinch, and the shell will break. Walnuts next year can blossom and bear fruit the next year after planting seedlings. Generally, there are 50 to 60 walnuts per kilogram, while the number of large walnuts produced in Hotan is only 33 per kilogram.

The main walnut producing areas in Xinjiang are Hotan, Kashi, Aksu, Yecheng, Kuqa, etc. According to the Forestry and Grassland Bureau of Hotan Prefecture, the total area of walnuts in Hotan Prefecture was 1.7194 million mu at the end of 2018, and the total output of walnuts in 2019 is expected to reach 276000 tons. It ranks first among all provinces and autonomous regions in China. In addition to selling all over China, our products are also exported to Japan, Britain, Australia and other countries.
