Originated in Central Asia, it is planted all over China. Generally, artificially improved varieties are selected, because the improved varieties have higher yield and thinner shell than wild varieties, which is commonly known as soaked walnuts. Wild shell thick, large, oil and other characteristics, eat more fragrant, commonly known as iron walnut. Walnut trees can be used as shelterbelts for road greening; Because its wood is tough and elastic, it is also the first-class material used in industry; Walnut shells can be processed into artworks.
