Cutting down forests, farming, planting cash crops, etc., these are the main "means" of human destruction of the earth, it is true that in the early days, everyone did not realize how important the earth that humans live on - the environment, but when they realized, the destruction has entered a state of extremization, so they are vigorously investing in maintenance, and finally over the years, human beings have made certain achievements in the maintenance of the earth, which is a good thing.
In recent years, after planting trees and building nature reserves in China, we have also seen more and more wild animals and plants appear in everyone's field of vision, which shows that the protection of the ecosystem has been effective. According to Zhejiang's survey data on aquatic vascular plants and periclusion algae, scientific researchers have found a rare plant - wild lettuce, which has aroused heated discussion.
According to the investigation report, the discovery of "wild lettuce" was also very unexpected, when the investigation team passed through the Village of Guangming in Yuqian Town, Lin'an District, it was inadvertently seen in the roadside pond, indeed, from the appearance of this plant, it is very easy to identify the wrong, because it looks like a "water lily". But the researchers felt extraordinary, so they looked at it, analyzed it, and didn't expect it to be an accident, actually "wild lettuce".
When many people see this plant, they will definitely think that it is a "water lily", and it is true that they are really too similar, but after confirmation, it is not a water lily, but a "wild lettuce". The area of wild lettuce found this time is not small, and the plant group found alone has an area of about 600 square meters, so it is very rare. Researchers said that the "wild lettuce" actually belongs to a widely distributed species, and it has its footprints in Pan'an, Jingning, Yongkang and other places.
However, this is limited to records and is rarely seen. The area of wild lettuce found in Lin'an this time may be the largest known wild lettuce population in Zhejiang Province, which has high conservation value. In ancient times, the plant has been well known to humans, and lettuce for people to eat, by the ancient Chinese literati praised as "Jiangnan Eight Water Daffodils", so it is a very long history of plants.
Obviously, when it comes to edible value, then there are definitely very few wild lettuce, and it can be said that as long as it can be eaten, there are very few that can stay. Lettuce we also call it ", horseshoe, lake vegetables" and so on, the appearance is similar to "water lilies", so it is very easy to identify the error, is a perennial aquatic root herb. In China, it is mainly distributed in Chongqing City, Zhejiang and Jiangsu Provinces, Taihu Lake Basin and Hubei Province, but now there are very few wild areas.
The main thing is that the young leaves of lettuce are edible, and there is no taste itself, so the taste is round, delicious and tender, one of the precious vegetables, plus the plant is rich in carbohydrates, vitamins and minerals, so people love to eat more, and it is also reasonable to call it "Jiangnan Eight Narcissus" in ancient times. Therefore, in this case, the wild collection of lettuce is also flooded, so the population size will inevitably be small.
Many people may not know that the plant as early as 1999, has been listed as a level I key protected wild plant in China, you can think of how scarce the plant is, so this time found such a large wild lettuce, we have to protect it well, otherwise it is a pity to disappear, and because it belongs to the level I key protected wild plants, then we can not destroy, it is not clear whether the area will be established as a key protection zone.
Of course, nowadays for lettuce can also take artificial cultivation, protection is also based on the "wild lettuce", so we don't have to worry about not being able to eat, as long as it can be cultivated, it must be available, this is the basic situation of wild lettuce, surprise is not unexpected, surprise is not surprised, scientific researchers must be very surprised, this is a big discovery.
The maintenance of the ecosystem depends on everyone, although everyone's awareness of protecting the environment has increased, we have also seen more wild animals and plants appear, which is good news, which directly shows that China's ecosystem has really become better, and everyone's efforts over the years are worth it.
The discovery of this plant population in Lin'an, Hangzhou, Zhejiang, can be said to also prove that the ecosystem maintenance in Zhejiang has achieved obvious results, if there is no protection, this pool has long been cleaned up.
There is no way to see what everyone calls "wild lettuce" today. We can also see the transformation of the ecosystem from the overall ecosystem change in Zhejiang, the forest coverage rate of the province has reached 61.50%, the forest stock has reached 445 million cubic meters, the vegetation resources are more than 3,000 species, and the national key protection of wild plants is as high as 45 species.
Therefore, Zhejiang is known as the "southeast plant treasure house". Therefore, Zhejiang is also one of the main areas where wild animals and plants live in China, and in the future, it will continue to protect and expand the population, and it will certainly be able to see more rare animals and plants recover.
