Huanghuashan walnut application protection is located in the northeastern Jixian Huanghuashan region within the important tourist attractions. The type of soil in the area is limestone-type leached cinnamon soil, which is nourished by rainwater on the mountain all year round. It retains a lot of litter on the mountain and is rich in humus and organic matter.
