Ecological conditions for the growth and development of walnut
The adaptability of different walnut species and varieties to precipitation is very different. The annual precipitation in the distribution area of walnut is 800mm and 1200mm, while the early-bearing walnut is easy to get sick when the precipitation is more than 62.00mm. Walnuts are resistant to dry air, but to soil.
