Walnut orchard intercropping can make full use of soil power and space, improve economic benefits, and supplement long-term and current benefits. However, in order not to affect the normal growth of walnut trees, do not plant high-stalk crops such as corn and millet during intercropping. Instead, intercrop beans, potatoes, and melons and vegetables. In order to solve the contradiction between planting trees and planting grains, sufficient growth space (nutrient zone) must be reserved for walnut trees when intercropping high-stalk crops. As the tree age increases, the intercropping area will gradually decrease, generally 80% in the first year, 70% in the second year, 60% in the third year and so on.
