Water Management In general, annual rainfall in the 600 ~ 800mm, and the area of ​​uniform rainfall distribution, can meet the needs of walnut growth and development.

Intercropping plants mainly include low stalk crops such as peanuts, millet, beans, and Chinese herbal medicines, and it is strictly prohibited to grow corn and other high stalk crops. When the intercropping should leave enough nutrition belt 1.5 meters to ensure the normal growth of walnut seedlings. Loose soil weeding. Weeds not only compete with walnut trees for water, but also prone to pests and diseases.
