Lichens are perennial plants that are organisms that are a combination of 1 species of fungus and 1 species of algae.

Because fungi and algae are closely united for a long time, they form an independent fixed organism in morphology, structure, physiology and genetics.

Lichens have always been mistaken for a special and single class of green plants, but they are not, lichens are a collective term for all fungi and algae that form a combination of special fungi. Worldwide, more than 500 genera and more than 26,000 species of lichens have been described. From the poles to the equator, from mountains to plains, from forests to deserts, lichens grow everywhere.

Most lichens are light-loving plants that require fresh air.

Therefore, lichens are not seen in the vicinity of densely populated industrial cities.

In a sense, the presence of lichens can be used to check the air quality of the city.

Lichens are generally slow to grow, but can tolerate prolonged droughts, dormant during droughts, and resume growth after rains, so they can grow on cliffs, rocks, tree bark, or desert ground. Lichens are hardy, so they are found in alpine zones, tundras, and poles.

China is quite rich in lichen resources, and people have a long history of edible and medicinal lichens.

According to incomplete statistics, there are 15 kinds of edible lichens in China, such as peel fruit coat, old dragon skin, reticulum lung coat, pine litmus, licos, stone fungus, tree flower, green tree hair, long pineapple, wind-rolled lichen, wind-rolled tea stains, etc. Among them, the stone fungus is a famous edible lichen of China and Japan, which can be stewed, fried, boiled in soup, cold dressing, rich in nutrition and delicious in taste.

After Chu Chu finished instructing his friends, he turned back to dig wild vegetables with his father.

She is not a person who can do things honestly and peacefully, and after digging up a few pieces of lichen, she began to turn her head and look around. Her eyes were very sharp, and when she glanced at it, she saw something crawling around not far away. So, he ran over and grabbed it and asked Cai Hongming for credit: "Dad." Look, Dad, I caught a bug. ”

Cai Hongming buried his head in digging lichens, and he didn't pay attention, so he let Chu Chu run away, and turned his head when he heard her words. I almost lost my soul.

What kind of insect is caught in the little guy's hand, it is clearly a small snake. Fortunately, it is not a poisonous snake, otherwise it would have been bitten and the consequences would have been unimaginable.

Cai Hongming hurriedly took the snake in her hand, pinched it to death, threw it far away, and then taught her daughter: "Chu Chu, this is not a bug, it is a snake." will bite. Some of this thing is also poisonous, and it will die if it is bitten, so when you see this kind of thing, you must find your parents, if your parents are not there, you will find the uncles and aunts on the farm, if they are not there, you will run quickly, and if you can't run, you will find something to kill it, do you know. ”

"Oh."

Chu Chu nodded. But how do you know anything, you probably turn around and forget about it.

There you have it. Cai Hongming no longer dared to let his daughter out of his sight easily.

After digging lichens and continuing to walk, Cai Hongming found that there were many plants growing here. There are things such as sand rice, sand bamboo, sand artemisia, sand whip, sand grass, pig hair cabbage, glazed grass and cat's head thorn and so on. The so-called sand bamboo here is not really bamboo, but a kind of grass.

Shami is not the rice we eat, but a herbaceous plant, but the seeds of sand rice can be eaten as rice. It's just smaller.

This thing is recorded in the "Compendium of Materia Medica": "Shapeng rice, all sandy land, especially produced in Ordos." The branches and leaves are like flax, and the rice is small like flax. As porridge, it is smooth and edible; Become the end. It can be filled with cakes, tea and soup. ”

Yuan Chengting has a poem "Send Pan Zhongming's Taixing" cloud: "Nianfeng sand and rice are cheap, and the river is close to the net and the fish is fresh." ”

And Ming Hu Shi's "Pearl Boat East Wall" also recorded: "Sweet, cool, silver, summer field, grass grows in the sand, as thin as a poppy, can be used for rice, commonly known as Dengsu, a sand rice."

There is a snack called sand rice noodles in Minqin, Gan Province, and the beauty of its meat and rice flavor can be said to be the best in noodles.

In addition to the seeds of sand rice, it can also be used for vegetables with its sprouts that grow in early spring. Other things such as sand artemisia, sand whip, sand grass, glazed grass, etc., cannot be eaten. Only the sprouts of pork hair cabbage and cat's head thorn can be eaten.

While walking, Cai Hongming told Chu Chu the names of various plants, and picked some by the way if he could eat them.

In addition to him, the animals in the family also have their own harvest.

The biggest harvest was the big rooster Huahua, who did not pick wild vegetables, but caught a sand pheasant. The sand grouse also didn't open his eyes, and even ate wild vegetables in front of Huahua, thinking that no one would see him if he squatted in the sand nest. Flowey is no ordinary chicken, she sees it at a glance, and immediately flappes her wings and flies over, grabs it with her sharp claws, and pecks it over with her mouth. Xiong Da and Xiong Er also found a few pieces of lichen, but the two guys dug lichen in a very good way, and they dug up lichen and sand together with a bear's paw. So much so that when the two stupid brothers brought the lichens to Cai Hongming, he didn't know whether they were digging sand or picking wild vegetables.

After these two guys followed Liu Chong, they ate and drank well every day, so they grew very fast, and their originally thin bodies became fat and looked very bloated.

The two guys walked in the ditch, and instead of picking a few wild vegetables, they stepped a lot of wild vegetables that could be picked into the sand.

This is clearly here to make trouble.

As soon as Cai Hongming saw it, he drove them to the back, so as not to worry about seeing them. But the most disturbing thing is the owl hero, this guy is not good at picking wild vegetables, but somehow he caught the little snake thrown out by Cai Hongming, and put it in front of him to ask for credit. was so angry that Cai Hongming beat it hard, making the hero very aggrieved and screaming over there.

Because the big rooster Huahua caught the most things, he walked majestic, high-spirited, and very energetic, feeling as if he was participating in the National Day military parade.

Jiaojiao, Xuexue and Xiaolong, who were protecting by Chu Chu's side, did not waste time, and also helped pick wild vegetables on the side. However, Cai Hongming disliked the saliva left by the two little guys who bit wild vegetables with their mouths, and only picked them a few times and didn't let them pick them, leaving only Xiaolong. The pika dragon is not very large, but it is very intelligent, and it never uses its mouth to bite things, but picks them with its claws. Although the amount is not very much, at least it is not as disgusting as the Tibetan mastiff horn horn and the sika deer Xuexue bite with their mouths and leave a bunch of saliva.

The ravines in the canyon, although large, are in the desert and there are not many edible plants that grow.

Even so, along the way, Cai Hongming and Chu Chu still harvested a bag of wild vegetables.

Walking to the end of the ditch, Cai Hongming unexpectedly found that there was a clump of new tender shallots that had just grown on the sand in front of him. Shallots tasted best for fried eggs and scrambled meat, so he dug some and left a little for it to grow.

Seeing that the wild vegetables were almost picked, Cai Hongming walked back.

Chu Chu's little fart walked a little sore, pouting and beating his calves with a pink mouth. Cai Hongming saw it, picked her up and sat on his neck. Chu Chu hugged his father's head and giggled happily.

"Squeak, squeak."

Suddenly, there was the cry of a pika dragon next to him. I saw it pointing to the mountain wall on the side of the ditch and squeaking, and I didn't know what it was calling. Cai Hongming looked curiously in the direction it pointed, and after looking at it for a while, he didn't see anything.

"What are you calling?" Cai Hongming asked Xiaolong strangely. But obviously, this question Xiaolong can't answer.

"Dad, Xiaolong said there was something in it." Chu Chu sat on his neck and translated seriously.

"You know what it's talking about?" Cai Hongming was surprised.

"Of course, I know what they say." Chu Chu looked proud.

Cai Hongming doesn't know if what she said is true or not, but regardless of whether it is true or not, you might as well give it a try. So, he put his daughter down, picked up the little hoe he had brought to dig wild vegetables, and went to the side of the mountain wall. The mountain walls are mostly sandy and easy to dig. Just digging inside, the sand layer becomes a layer of earth and rock. The soil and rock layer is a bit hard, but in the scorching desert, even the hardest soil and rock layer will be softened by the sun, so it is not difficult to dig.

After digging about two meters forward, I saw only a piece of dirt and stones, but I couldn't see anything.

Most of the stones are goose warm stones that are common on river beaches.

From this, it can be seen that this ditch must have been a turbulent river in the past. It's just that these are of no use to what he's going to dig up at all. After digging for a while, seeing that he still couldn't dig anything, Cai Hongming wanted to give up. Suddenly, a golden light flashed in front of him. He didn't know if he was dazzled, but this undoubtedly gave him endless motivation, and he immediately dug it up quickly. (To be continued.) )
