The difference between islet fruit and ginger

There is no difference between islet fruit and ginger.

Islet nuts and ginger are the same thing, but they are called differently. Islet fruit, also known as ginger, can also be called Jerusalem artichoke. Of course, it is planted in different geographical locations, and there are many other aliases. It was originally the product of growing in the United States, and gradually swept the north and south of China in the process of economic and cultural exchanges.

Islet fruit has strong adaptability to the environment, cold tolerance, drought tolerance and salt tolerance. In winter, the tuber of ginger can withstand the low temperature of MINUS 30-40 degrees, and it is not afraid of frost (non-extreme weather) after germination in spring. It can also survive well in arid and saline-alkali areas where other plants can't grow normally (except in extreme environment).

Islet fruit is propagated by tuber, with high yield. Part of the land germinates in spring and withers before winter comes. After winter, the tubers germinated again, and it was a new round. As long as the environment is suitable, there will be endless offspring.
