What method is used to dig and wash lotus roots in a large area?

The large-scale planting of lotus root is completed by manual digging and washing.

Because lotus root is brittle, it should not be broken when harvesting, otherwise the value of lotus root will be greatly reduced, so it is not suitable for mining with mechanical equipment. It is difficult to dig, and the lotus root is often dug manually with tools such as hoes and shovels. The silt in the lotus root growth area is thick, which is not convenient for workers to carry out their work.

After digging out the lotus root, the workers will directly clean it manually in the pond. Under normal circumstances, a worker can only dig and wash 100- 150 Jin of lotus root a day, which is labor intensive and very inefficient.

Storage method of lotus root

The uncut lotus root can be stored for one week at room temperature, but the cut lotus root is easy to turn black and rot, so the cut lotus root should be covered with plastic wrap and refrigerated for about one week.

If there are not many lotus roots, they can be stored in a water tank. First, wash the lotus root, put it in a jar filled with clear water, and change the water once a week. It can be preserved for about 2 months, and it can still be white, tender and crisp.

If the quantity is too large, you can dig a pit and spread a layer of fine wet soil at the bottom of the pit, then choose lotus roots with good quality, thick stems and complete roots to spread a layer evenly, then spread a layer of wet soil, and then spread lotus roots, so that you can put 5-6 layers, with the top layer covered with fine soil of about 10cm, and finally cover with a thick layer of leaves and firewood, so that you can take it with you when eating.
