In dry, well-drained soil, dig a hole one meter long and wide, lay it on the ground with clean gauze, put the walnut kernels in, and cover with a layer of gauze. Then put a thin tube on the walnut kernel every 5cm for ventilation.

Then put it in a low-temperature environment and make sure the air humidity is low.
