Storage of walnuts at room temperature can be divided into dry storage and wet storage
1. dry storage will be stripped of green walnuts placed in a dry, ventilated place in the shade, drying to the diaphragm of the nut a fold that is broken, the seed coat and seed kernel is not easy to separate, the seed kernel color inside and outside of the same, it can be stored. Dry walnuts in a sack, placed in a ventilated, cool, light is not directly high pressure to the room. Storage period to prevent rodent damage, mold and fever and other phenomena.
2. Wet storage in the terrain of high and dry, well-drained, before the shade of the wind dug a depth of 1 meter wide 1.5 meters long with, depending on the amount of storage ditch. The bottom of the ditch first lay a layer of 10 centimeters thick clean wet sand, the humidity of the sand to the hand pinch into the concordance but not out of water to the degree. Then a layer of walnuts a layer of sand paved, ditch walls and walnuts between the wet sand filling, leaving no gaps. Paved to about 20 centimeters from the mouth of the ditch, and then cover the wet sand and ground level, sand on the soil was roof-shaped, its span is greater than the width of the ditch. Ditch around the opening of the drainage ditch, to avoid too much rainwater infiltration, resulting in high humidity, easy to make the walnut mold roasting. Ditch length of more than 2 meters, in the walnut storage should be every 2 meters vertical a handful of tightly tied straw for ventilation holes, the height of the grass to reveal the "ridge" to the extent. "Ridge" of the soil thickness varies with the weather, cold areas in winter to build thicker.
