Thin-skinned walnut is a kind of walnut, which is easy to shell and rich in nutrition. The shape of intact walnut kernel is quite similar to that of human brain, so it has been used as both medicine and food for nourishing and strengthening the brain since ancient times, and is known as "educational fruit". Walnut, formerly known as walnut and peach, is native to southeastern Europe and western and southern Asia. Walnut kernel is rich in nutrition, which is not only an ideal nourishing product, but also a "healthy friend" of dietotherapy. Walnut is mainly rich in fat, which contains linoleic acid glyceride, linolenic acid glyceride and oleic acid glyceride, which is beneficial to reduce the increase of cholesterol in blood and has a health care effect on patients with arteriosclerosis and cardiovascular and cerebrovascular diseases.

Thin-skinned walnuts are strict with environmental conditions. Thin-skinned walnut has a wide adaptability to soil, but because it is a deep-rooted fruit tree, its stress resistance is weak, so it is more suitable to choose deep fertile loam with strong water retention. Thin-skinned walnut is a fruit tree that likes light and needs sufficient light. It is best to choose the south slope to build a garden in mountainous areas. Compared with traditional walnuts, thin-skinned walnuts can bear fruit three years earlier. The skin is as thin as paper, and the walnut shell can be crushed by hand. Many people also call it "paper walnut". Moreover, this new variety of walnut has early maturity, good taste and high oil content, and its economic value is 2 to 3 times higher than that of the old variety of walnut. Grafted seedlings can bear fruit in 2-3 years, and enter the high-yield period in 4-5 years.
