Please see the following analysis for specific difficulties:
First, although there are many botanical gardens in China, many kinds of them are beautiful, and ordinary plants can only be handed down by their elders.
In China, there are many botanical gardens, but most of them are planted according to the garden pattern. After all, botanical gardens also need to be opened. Only the whole flower sea can slowly recover the funds invested by the botanical garden, but it is basically scientific, only horticultural plants. Other ordinary plants can't observe and learn systematically, and botanical gardens don't have the same interaction as zoos. If they are not beautiful enough, they are extremely boring.

Like some rural elders, there is also the practice of word of mouth, but most of them are in dialect form, and there is no accurate plant classification; Now, most newly married young people have moved to the city with their families. Because there are not many plants in their education and living environment, word of mouth is also the fault of this generation. Except those who have entered the farming industry, others are basically unknown, let alone passed on to the next generation.

Second, the selected area is obviously planted, but the * * * shape of the plant itself is ignored.
At present, there are many economic tree species, but most of them are aimed at the whole economic tree species, ignoring the native tree species that originally grew in that land. At the same time, in order to protect the growth of economic trees, grasses, herbs, mosses and other plants are disappearing, and even some herbs have been declared extinct before being discovered.

Take some deciduous trees for example, there will be a mat near their dry roots, plants similar to wild anoectochilus will appear near their wet roots, and parasitic fruits will also appear on the trees. Like Illicium verum in my hometown, because of weeding and picking fruits every year, the number of ground grass is gradually decreasing, because it is an Illicium verum weed and needs to be removed.

Wild anoectochilus roxburghii has become extremely rare because of its increasing value and the area of rural cash crops, and it needs to be planted for medicinal purposes. However, it is impossible to simulate the wild environment after planting, and the thread of anoectochilus roxburghii is gradually losing gold.
Third, there is no professional video identification channel, and most popular science plants rely on books.
Now is the era of small video. In 2020, many lectures will be conducted in the form of network. However, short videos from all walks of life are slowly increasing, while videos related to plant science popularization are almost stagnant. Unprofessional live broadcasters cannot identify species; Professionals, because of full-time scientific research, have not been exposed to live broadcasts and small videos, and have no professional shooting skills.
Of course, there are books about plants all the time, and most of them are equipped with maps. There are thousands of plants in one family and one genus, which cost 19.9 yuan's popular science books, most of which are only 100 pages. The cost of understanding plants is not low. Not everyone in the family factory has a chance to identify it on the spot. However, there are not many regional plant publications. Standing in the wild, it is often a dozen plants to turn over more than ten books.
Li Yanhong said in the live broadcast that he intends to complete this knowledge platform about plants. Although this road may not be very smooth, it is a big project that is difficult at this stage and benefits future generations. Perhaps this is the role of Baidu as a knowledge platform.
