I want to grow walnuts in Tianshui, Gansu. I don't know which variety is suitable.

The climate of Gansu province belongs to temperate monsoon climate, which has obvious characteristics of transition to continental climate. The province is dry with little rain and large temperature difference. The climate of the four seasons is characterized by: less rain and snow in winter and long cold time; In spring, the temperature rises rapidly and changes greatly; Summer temperature is high and precipitation is concentrated; The temperature drops rapidly in autumn, and the first frost comes early.

Walnut tree is called "lazy tree", which is a kind of fruit tree variety that is easy to manage. According to the climatic conditions in Gansu, it can be planted, but it is necessary to choose the right time, pay attention to moisturizing, prevent cold and insects. It is best to plant in autumn, and take measures to keep warm and prevent freezing, which will help to improve the survival rate in the coming year.

At present, the new products of early-bearing thin-skinned walnuts are of high quality, such as Guanhe 1 walnut, which is planted in barren hills and slopes and cold northeast China.
