Optimum temperature for water chestnut storage: 0-2, relative humidity: 98-100%.
When the stems and leaves on the ground are naturally yellow and withered, use a nail rake to moderately turn the soil, pick up the bulbs, remove the soil, and do not wash it. When it is marketed, the bulbs are divided into large and small balls according to the individual bulbs and then dried in the shade and packed into cartons. If the harvested bulbs are immediately impregnated with sodium hypochlorite solution, they can be stored for 10 months at 0 and 8 months at 5.
The concentration of sodium hypochlorite solution decreases to about zero within 3 to 5 days.

1. Kiln storage.
If the old kiln is used for storage, before storage, it should be disinfected with carbendazim or 40%-methyl tobuzine 400-500 times at the bottom of the kiln and on the kiln body. Spread a layer of fine soil at the bottom of the kiln, put a 20-25 cm thick water chestnut, sprinkle a layer of dry fine soil on it, so that a layer of fruit sprinkled with a layer of soil, until 20 cm away from the kiln mouth, it is sealed with dry fine soil filling, and the surrounding is capped with 30 cm thick soil, forming a steamed bun shape with high and low surrounding, covering the kiln mouth and patting.
2. Sand storage. After the water chestnuts are dug up, they are built with bricks in a shady house or basement, a buried pit, and the bottom of the pit is first covered with 5-7 cm thick fine sand, and the water chestnut bulbs are arranged on the sand surface, covered with fine sand 3-4 cm thick, and then the water chestnut bulbs are discharged, so that they are stacked layer by layer, and the height of the pile is not more than 1 meter. This method can also play a good role in storage and preservation.
3. Soak the solution.
The harvested water chestnut bulbs were removed from impurities, and quickly immersed in sodium hypochlorite solution for storage after washing. According to the test, using this method, when the temperature is in 0-2, the relative humidity is 90%-100% storage environment of water chestnut bulb can be kept fresh for up to 10 months, and the storage period below 5 can reach 6-8 months.

We produce water chestnuts here, and we really don't know a better way to keep them for a longer period of time. We usually dig and sell here while digging, and after the water chestnuts are dug out of the ground, they are slightly dried and stored with mud, and the storage time is slightly longer. If you are a vendor, you can wash as much as you sell every day.
Now is the season to eat water chestnuts, welcome all friends who need to contact me, wholesale and retail can be, **Want Want name and here the same name. Hehe, if it's not sweet, I don't want money!
I checked the information below, and I don't know if it's the answer the landlord wants:
After the harvest of water chestnuts, farmers can effectively prolong the shelf life of water chestnuts and increase the sales value of the products according to the following simple methods.
After the water chestnut is harvested, remove the soil and sundries on the bulb skin, remove the diseased and injured bulbs, spread it on the brick ground for 12 15 days, and after proper drying, the water chestnut is placed in a large indoor pottery jar (the clay jar with pickled vegetables cannot be used, and the pottery jar should be placed in a dry and ventilated place). Each jar has a capacity of about 80 100 kg, and the mouth of the jar full of water chestnuts is capped. It should be noted that:
Water chestnuts stored in clay jars have a strong respiration effect in the early stage of storage, and the cylinder cover must be opened to facilitate ventilation and dissipate moisture in the jar; In the rainy season, due to the high humidity in the air, the water content of water chestnuts will increase rapidly, and the cover should be removed in time; In the hot and humid season, due to the rapid evaporation of water, it is necessary to cover it in time to prevent the water in the water bulb from evaporating and causing dry rot. During the storage process, the water chestnuts stored in the clay jar should be turned over and checked every 25 to 30 days. According to the above method of storage, the shelf life of water chestnuts can reach more than half a year.
After the water chestnut is harvested, in a shady house or basement, build a burial pit with bricks, lay 5 7 cm thick fine sand at the bottom of the pit, arrange the water chestnut bulbs on the dry sand, and cover it with fine sand 3 4 cm, and then discharge the water chestnut bulbs on the sand according to the above method, and continue to stack them, but the total height of the stack does not exceed 1 meter. This method has a good storage and preservation effect.
Solution storage and preservation: The harvested water chestnut bulbs are cleaned and quickly immersed in sodium hypochlorite solution for storage. According to the test, using this method of storage, in the storage environment of temperature 0 2 and relative humidity 98 100, the freshness period of water chestnut bulbs can reach 10 months, and the storage period below 5 can reach 6 8 months.
