Tang Qinqin and the others returned to the team and prepared to go to the next game location.

"Hey, when I had nothing to do with my phone yesterday, I found a good thing and thought it was useful, do you want to take a look."

Yang Qing leaned over, took out the materials she had prepared, and on a stack of bound A4 paper, the top one was written in black block letters in black block letters.

"Hey, that sounds pretty big." Tang Qinqin sat down and looked at it carefully.

"Is the technology so powerful now?" The more he looked down, the more Tang Qinqin was amazed, the technology he didn't dare to think of had been put into application and was constantly improving and improving.

"No soil spraying, guest soil spraying technology ......" Tang Qinqin's eyes lit up, isn't this a treasure!

Soilless spraying is a soil covering process that uses wood fiber substrate instead of soil for spraying. Seeds, fertilizer, water, wood fibers and other substances are stirred together by spraying equipment, mixed evenly and then sprayed on the place where greenery is needed.

Soil spraying is to establish a substrate layer on the rocky slope to prevent plant growth from erosion, and then spray seeds on the substrate layer to achieve the purpose of vegetation restoration after later maintenance.

Among them, guest soil refers to the non-local native soil, which is moved from elsewhere to replace the native soil, usually refers to the loam soil with good texture (sandy loam soil) or artificial soil, which generally needs to be activated and improved.

As a result, the Players Ad Hoc Meeting was held again.

After the meeting, it was unanimously approved to use this compulsory greening method for ecological restoration.

It is used to remedy the local ecological environment vacancy after Eupatorium was eliminated.

This time, Song Yuanze exchanged 3000 points for a multi-functional spraying equipment vehicle, which integrates the advantages of various current spraying technologies and has uniform seed spraying coverage; Good water storage and thermal insulation performance; Strong adhesion, resistant to rain, wind and sand; improve soil fertility; Low investment, quick results, improve construction efficiency, save manpower, financial resources and other characteristics.

Tang Qinqin's "Thirteen-Character Factory" has now become a warehouse, which is specially used to store the bundled purple-stemmed Zelan.

When he saw that Song Yuanze was 3,000 points as soon as he made a shot, Shen Jinsong was surprised.

"Boss," the current Shen Jinsong has consciously changed his words: "Do you have so many points?" ”

It's no wonder that he can throw his former number one far away on the leaderboard.

"You'll have it later." Song Yuanze said simply.

In the past, it was possible to rank first just by ordinary game tasks, which shows the strength.

Get ready and head to the next Purple Stem Zeeland play area.

This time the game is set in a vast farmland.

In the fields, on the side of the road, everywhere the eye can see, there are figures of Eupatorium purpurea.

Opening the live broadcast equipment in the backpack that was exchanged for 200 points, Tang Qinqin started the first live broadcast content - live weeding.

The live broadcast room was named "a hazelnut".

The live broadcast room that just opened was empty, and occasionally flashed in a few people, and I didn't see anything of interest, so I left decisively.

Tang Qinqin didn't know how to broadcast live, thinking about what he should do and what to do, so he let the camera go and concentrate on doing his own thing.

Lan Lan and Mengru also started a live broadcast, and Lan Lan, who has a lively personality, is more comfortable with the live broadcast, and at this moment, I heard her talking happily while busy pulling weeds in her hands.

Looking at Mengru, who was as silent as himself, Tang Qinqin thought to himself, fortunately, Mengru accompanied me.

"Hey, what's going on here? It looks like ...... Pulling weeds in the field? Do you do farm work? ”

Tang Qinqin heard a strange voice ringing in her ears, she was slightly stunned for a while, and hurriedly said: "Hello, this is the live broadcast of uprooting the purple stem Zeland, the plant in my hand, this is the purple stem Zeland, it is an invasive weed that is harmful to our agriculture and ecology, and it must be eliminated." ”

This set of equipment redeemed from the game points mall can automatically convert the audience's barrage into voice form, especially suitable for Tang Qinqin's situation that he can't care about looking at the screen at the moment, and he can also interact with the audience through voice and conduct live broadcasts.

However, when the voice is live, the audience's name is hidden, and Tang Qinqin can't see it for the time being.

"What are you doing, hey, a lot of people, what kind of flowers are they in their hands."

Another newcomer entered the live broadcast room, and with a curious look, Tang Qinqin edited an introduction to Purple Stem Zelan and posted it.

"Hey, Purple Stem Zeland? Nice name. ”

"Didn't you listen to the anchor, this is a poisonous grass, and the name is good and useless."

"This purple-stemmed Zeeland looks a little familiar. By the way, isn't it airplane grass? ”

"No, the airplane grass you are talking about is also called vanzelan, pioneer grass, and Eupatorium purpurea belong to the same perennial plant of the Asteraceae family, but they are very different from each other."

Tang Qinqin said and raised a purple-stemmed Zeetium in his hand, pointed to its stem and said, "You see, the stem of the purple-stemmed Zeuplen is purple, with a height of 30-200 centimeters, and there are such white or rust-colored pubescence on it. On the other hand, the stems are green, with pinstripes, and can be 1-3 meters high, and in addition, their capitate inflorescences are not the same shape. ”

"They look similar at first glance, but the flowers of airplane grass are more varied, ranging from pale greenish yellow, greenish-white, and slightly lavender, while the flowers of Eupatorium purpurea are white."

"Oh, I see. I thought they were plants. Learned, learned. ”

"I should have seen it too, it's a little familiar, I didn't take it seriously before, and I'll report it next time I see it."

"Haha, that's right, it's an invasive species, encroaching on grassland, invading farmland, and having strong fecundity.

Tang Qinqin said.

"When it comes to invasive species in plants, there are also water hyacinths, goldenrod in Canada, hollow lotus seed grass, Spartina alterniflora, etc., you can usually learn more about it."

"I swiped it on my phone a while ago, anchor, is it dangerous?"

"I don't need the anchor to answer this, I can tell you. Canadian goldenrod, known as a flower after the flower kills, also known as the overlord flower, strong fecundity, not only through seed propagation, but also through the root expansion, and it also has the same killer feature of purple stem Zeland, has an allelopathic effect on other plants, inhibits growth, generally where it exists, it is not an inch of grass. ”

"I found that these invasive species all seem to have one thing in common, they are very fecund, they are very domineering, and they are arrogant enough."

"Can you study its characteristics and apply it where it is needed?"

"I've also seen the Canadian goldenrod you mentioned, I saw it in the park, and I thought it was novel and beautiful at the time, it turned out to be an invasive species, anchor, if we find these harmful plants, wouldn't it be good for us to pull them out ourselves?"

"I don't recommend direct contact with their plants, because these domineering plants are generally poisonous, and direct contact can be dangerous, if we find traces of them, we can report them to the relevant departments and let them handle it more professionally, more appropriately."

Tang Qinqin reminded loudly: "Everyone should try not to have direct contact with the unfamiliar animals and plants they see in life, so as not to be harmed, you can be curious, but first of all, you must protect yourself." ”

"Then anchor, can you just throw away this grass after pulling it out? Why did it invade us? Won't it grow back after that? ”

"Purple stem Zelan is a double-edged sword, it is harmful, but it is also useful, after pulling it out, we plan to recycle it and squeeze out the use value." Tang Qinqin said with a smile, "This can be regarded as a tribute to their arrogance and presumptuousness on our territory and plundering the living space of native species." ”

"The emergence of invasive species is mostly related to human activities, such as the two domineering plants we just mentioned, which were originally introduced as ornamental plants. In addition, their seeds can also be spread by wind, birds, and other animals, and spread quickly when exposed to suitable conditions. ”
