Walnut is a walnut plant of Juglandaceae. Together with almonds, cashews and hazelnuts, it is known as the world-famous "four dried fruits". Walnut kernel is rich in nutrition and fat, and contains calcium, phosphorus, iron and other trace elements and minerals, as well as carotene, riboflavin and other vitamins. It's good for the human body. It is a kind of nut food deeply loved by ordinary people. The outer shell of the body surface is hard and needs to be broken open to eat.

Walnut likes light, cold resistance, drought resistance and disease resistance, adapts to the growth of various soils, and likes fertile and humid sandy loam, water, fertilizer and sunshine. At the same time, the requirements for water and fertilizer are not strict, and it is not suitable for pruning after defoliation and before germination, which is easy to cause bleeding. Suitable for most land growth. Calcareous soil is common in deep soil on both sides of the valley.

Walnuts are widely distributed in China, including Heilongjiang, Liaoning, Tianjin, Beijing, Hebei, Shandong, Shanxi, Shaanxi, Ningxia, Qinghai, Gansu, Xinjiang, Henan, Anhui, Jiangsu, Hubei, Hunan, Guangxi, Sichuan, Guizhou, Yunnan and Tibet.
