The reporter visited many parks and found that the phenomenon of tourists digging wild vegetables is very common. On Sunday morning, the Olympic Forest Park welcomed a large number of morning runners. In the warm and cold season, the land has not completely turned green, but in the park, the cold resistant February orchid has grown into a piece of green, some tourists come to take photos, and some tourists take bags to pick February orchid.
In the South Park of the Olympic Forest Park, a large area of February orchids are in bud, and blue and purple flowers bloom in sunny places. Although there are signs everywhere in the park saying 'no picking fruits and vegetables', tourists still come into the forest from time to time to pick wild vegetables at will.
The reporter saw at the scene that the two old people picked plastic bags and environmental protection cloth bags for a long time, and most of the bags in their hands had been filled. They hold the tender tip of February orchid and choose it back and forth. One of the aunts also introduced her experience to the reporter: "when picking, you have to pinch the tip, and it will be longer after pinching. 'aunt said that after picking the wild vegetables back, you can eat them cold or fried, and you can also make stuffing. 'February orchid tastes a little bitter. It's because of the bitter taste that it goes to the fire. Another old man added: 'this dish is high in calcium and is also called Zhuge dish. It is said that Zhuge Liang used it as military food. '
After pinching one piece, aunt continued to look for the next destination. On a sunny slope, the orchid of February here has blossomed a large number of flowers. The young plants that have just blossomed are also plucked away by my mother. "The flowers of February orchid can also be eaten. The reporter saw that many flower stems had been cut off.

In the public toilet of the park, some people are cleaning the newly dug wild vegetables. The reporter saw the notice posted in the park in the bathroom: for the convenience of you and others, it is forbidden to dig and wash wild vegetables.
Mr. Gao, a citizen, runs and walks in Orson park almost every day. He told reporters that the area of Orson park is large, and the vegetation in many places maintains its original ecology.

'Mr. Gao said.

The reporter also saw in Dongba country park that a large area of February orchid under the tree had been 'swept away'. Many plants had not yet grown up, and the part growing on the ground had been pinched off, leaving only flower roots. Mr. Zhang, who is picking wild vegetables here, said that February orchid is also called 'wild rape' in his hometown Sichuan. Every spring, he would pick some to satisfy his hunger. In order to pick wild vegetables, he didn't even go to the 'Sailor Dance' which he paid to sign up for. He usually had to go to work, so he had to rest today. In a few days, the flowers would bloom, and it would not be delicious. '
A green worker in the park said that people are often seen digging wild vegetables here. "They dig everything with their hands, with knives and keys. The grass is often dug in a mess. 'in this situation, they want to manage but dare not. After all,' we are just workers. 'There are security guards who will dissuade you when you meet them, 'but the garden is too big for you. '

Ms. Zhang, a citizen, told the Beijing news that the dandelions in the green space of the community were all dug up by roots. "There are several toon trees in our community. At this time of year, the sprouts of Toon trees are broken off. I don't know what tools can be used to break off the sprouts of Toon trees on the tree tips. And I don't think it's Chinese toon. Can you eat it when you break it back? "
Expert: some wild vegetables are poisonous and easily polluted
Hu bin, senior agronomist of Beijing plant protection station and deputy chief of the vegetable crop section, said that from the perspective of nutrition, most wild vegetables have closely related cultivated vegetable varieties with similar nutrition and taste, and their cultivation environment is more healthy than parks and woodlands.
Hu Bin said that there are many kinds of wild vegetables, which are easy to be confused. For example, sowthistle and Ixeris are easy to be confused; young plants of shepherd's purse are easy to be confused with Gracilaria and freestyle; Viola yedoensis is easy to be confused with early viola. And a small number of wild vegetables have small or slight toxicity, which need special processing before they can be eaten. There are also some wild vegetables that can't be eaten. For example, poisonous celery is similar to water celery, but poisonous celery is poisonous.
