Is Handan, Hebei suitable for growing walnuts? Please recommend several varieties!

The annual average temperature in Handan is 13.5℃, the average temperature in Leng Yue (1 month) is -2.3℃, the extreme minimum temperature is-19℃, the average temperature in the hottest month (July) is 26.9℃, and the extreme maximum temperature is 42.5℃. The frost-free period is 200 days and the annual sunshine is 2557 hours. Climatic conditions are completely suitable for the production of high-quality walnuts. The rest depends on the conditions of the park. It is best to have sunny slopes, gentle slopes, or land with higher terrain and no stagnant water. This kind of land is best if it can have water. If it is flat land, it needs irrigation and drainage conditions, and it cannot accumulate water for a long time in rainy season. Generally, the walnut orchard will be seriously ill after 2-3 days of water accumulation, and it will die after a long time.

In terms of varieties, Liaohe 1 and Xiangling are the most reliable, with comprehensive economic benefits, convenient management and strong cold resistance. I prefer Liaohe 1. Some new varieties can only be introduced and tested in small quantities, and cannot be blindly developed in large areas to avoid investment mistakes. In addition, it is not uncommon to pay attention to false seedlings.
