Differences between Tiegun Yam and Common Yam

Pitaya is usually planted in summer, when the temperature is suitable for its growth. The plant is not strict with the soil, if you want to develop better and faster, you usually need to use loose and fertile potting soil, and add fermented chicken manure as base fertilizer. The seedlings should be watered regularly to keep moist, and a little urea should be applied at the same time. In winter, we should pay attention to cold prevention, the temperature should not be lower than 10 C, otherwise the plants will be frostbitten. Generally, the fruits are ripe from May to November, and they can be picked at that time.

1. Epidermal Difference

There are obvious differences between the two varieties, which can be distinguished from the epidermis first.Tiegun Yam has rough surface, obvious pore lumps, dense hair and purple spots on its surface.But the ordinary Chinese yam epidermis whole is smooth, the pore lump is not obvious, the hair is also sparse, the distribution is scattered.

2. shape difference

In addition to shape, it can also be distinguished by shape.Iron stick yam is thin, about 1-1.5 cm in thickness, with different lengths, round head and sharp tail.The common yam is relatively strong, about 4-5 centimeters in thickness, and its shape is irregular.

3. Qualitative region

Iron stick yam texture is relatively more compact, delicate, fine fiber.It is very strong and does not break easily.The common yam has a lot of water and is very watery.Usually, water can be pinched out by hand, which is easy to be broken, so it should be taken very carefully.

Fourth, taste difference

The difference in taste between the two is also very large, and it is easy to taste the difference.Iron stick yam on the pot steaming or boiling, about only minutes of time will be cooked, and taste dry noodles, sweet, and cooked for a long time.The common yam is crisp even if it is cooked for a longer time, so it is often made into a refreshing dish.
