China has a vast territory and abundant resources, but even so, it is necessary to introduce some species from abroad. After all, some species are still very useful for people. For example, the fruits introduced from abroad in recent years not only meet people's daily needs, but also let farmers have more varieties that can be planted or cultivated.

However, in the past, people were not familiar with alien introduced species, which led to the introduction of many invasive species, such as Spartina alterniflora, water hyacinth, bullfrog, crayfish and other exotic species. Because they have almost no natural enemies in our country, they once had a serious impact on the local ecosystem of China. Fortunately, people found problems in time These alien species have been controlled in various ways.

Among them, crayfish and bullfrog are the best examples. They are still rampant in many foreign countries, but in China, they have to be fed by farming.

In the front and back of houses in rural areas, you can always see many climbing weeds. They will climb up the walls and tree trunks. They are very vigorous. They can also spread all over the country. Among them, there is an invasive plant called "tengsanqi". Now, in some areas of the south, we mention tengsanqi, or its commonly known as "bean curd leaf", "anemone" and "luokui potato". Everyone says that it is a very delicious vegetable, but we don't know that it is an invasive species as terrible as crayfish and bullfrog.

The harm of Panax notoginseng.

At first glance, the name of Panax notoginseng seems to be related to Panax notoginseng, but actually Panax notoginseng is totally different. Panax notoginseng is a plant of acanthopanaceae, while notoginseng is a plant native to China, and rattan Panax notoginseng is a plant native to Brazil.

Rattan was discovered in the 18th century and was introduced to the UK in the 1820s and later introduced to other parts of the world. Nowadays, rattan Panax notoginseng exists in most countries of the world. However, due to its extremely strong fecundity, it propagates vigorously in the wild. It can grow one meter in a week, three to six meters in a growing season, and it is difficult to cut off the roots. Therefore, it crawls all over the house without paying attention.

Foreigners have thought of many ways, and even released insects that specially eat leaves to deal with it, but all of them have little effect. Therefore, rattan Sanchi has become an invasive plant that makes foreigners headache, and it is still rampant in foreign countries.

Panax notoginseng was introduced into China as an ornamental and medicinal plant in 1976, and it was planted in northern China. In the early days, it was once rampant in the countryside of our country. However, due to its proper application in our country, Teng Sanqi was not only unable to spread, but also served on the table.

The value of Panax notoginseng.

The application of Panax notoginseng in China is mainly in two aspects, one is medicinal, the other is edible as vegetables.

The bulbil bud of Panax notoginseng (i.e. the fruit of Panax notoginseng, which looks a bit like Panax notoginseng), contains polysaccharides, flavonoids, saponins, amino acids, vitamins and other ingredients, which makes it have a good tonic and strong waist and knee function.

The leaves and tender shoots of Panax notoginseng can be used as vegetables, and its nutritional value is very rich, including potassium, phosphorus, calcium, sodium, magnesium and other major elements, as well as iron, manganese, zinc and other trace elements, especially the content of iron is higher than most vegetables.

Conclusion:

The leaves and tender shoots of Panax notoginseng don't have a special taste. It tastes like a kind of fungus and bean curd. It tastes smooth and tender. Therefore, it is also called "bean curd leaf" and "agaric" in the folk. There are many ways to eat it, such as stir frying, cold mixing and making soup.

In addition, the strong fecundity and rapid growth of Panax notoginseng make it not only easy to plant, but also has a short picking period. It can be harvested once every 15-20 days in the early growth stage, and once in 10-15 days in the middle and late stage. If properly managed, it can be harvested all the year round. This advantage also makes tengsanqi become a "lazy vegetable" loved by many farmers in some rural areas in southern China.
