1. Mustard looks like an ordinary root vegetable. How expensive can it be? Wasabi is called "mustard", which is volatile and can only be eaten and ground now. As a popular condiment of Japanese cuisine sashimi, wasabi is not only delicious and nutritious, but also has many pharmacological effects such as anti-epidemic, anti-bacterial, anti-cancer and anti-oxidation. Due to the special growth conditions and limited land suitable for planting, the products of wasabi are extremely scarce in the international market, so the price of wasabi is also rising. The vacuum-packed wasabi is about 170-200 yuan/kg. Second, gemmule chicory looks ordinary, but its life experience is unusual! Gemmule chicory is a kind of European royal vegetable, which originated in the Netherlands and is known as the "king of vegetables", and has been selling well in European and American markets. Many people think it looks like magnolia, also called magnolia. The planting method of chicory in bud is very complicated. First of all, we should plant roots in the ground, and then dig roots for softening cultivation four months later. In this process, the less light you see, the more money you get. When you see the light, you can only sell it for 8 yuan, while a catty grown in the dark can sell for 40 yuan, or even higher, and its value has soared five times! Third, five-color leeks Perhaps you have seen such leeks? Five-color leek, as the name implies, a "five-color leek" has five colors: white, yellow, green, red and purple. Compared with common leeks, five-color leeks are fine in fiber, delicious, moist and slightly spicy. Five-color leek is very strict in cultivation and planting technology, and can only be cultivated after the cold weather in winter. The subsequent treatment requires a lot of labor and the process is complicated. Winter cultivation leads to the listing of five-color leeks more than two months earlier than ordinary leeks, which coincides with the Spring Festival and has a unique appearance, so the price is also expensive. During the Spring Festival in 2006, this five-color leek was sold to 40 yuan/Jin as soon as it was put on the market. Fourth, Euryale ferox is known as the first of the Eight Immortals in Jiangnan Water Town! Because its fruit is spherical and the top is embossed with patterns, it looks like a chicken head, so it is also called "chicken head rice". Chicken's head rice is called ginseng in water, which is rich in protein, carotene, crude fiber and various trace elements, and has high nutritional value. It is so expensive, not only because of its own efficacy, but also because it is hard to come by. The fruit of the chicken's head rice is covered with hard thorns, all hidden under huge leaves. When harvesting, it can only be harvested by hand with a sickle, which is very rare and the processing technology is very complicated. The price of fresh hand-peeled chicken head rice ranges from 30-60 yuan/kg. 5. Carrot Mountain Carrot Mountain Carrot is a good wild vegetable. Its scientific name is "Mihua Rock Wind", also known as Radix Adenophorae. As a scarce variety of carrots, the roots and leaves of wild carrots can be used, and they are rich in dietary fiber, vitamins, carotene, 17 kinds of essential amino acids, ketone flavonoids and apigenin. Due to the limitation of growing environment, it is impossible to grow wild carrots on a large scale at present, so the price of wild carrots "native to rural areas of Shan Ye" is relatively expensive. The current market price of wild carrots is around 20-30 yuan/kg.
