Starting from Qinglin County, Lin Han drove alone and began to sweep the city's invasive plants.

These invasive plants, both terrestrial and aquatic, such as poison weeds, goldenrod canadensis, hollow lotus seed grass, and so on.

With Lin Han's rapid sweep, the invasive plants in Yunzhou City were like falling dominoes, dying in pieces.

Only a few days have passed, and under Lin Han's powerful "anti-green buff", the city's invasive plants have been almost cleaned up.

In the southwest of Yunzhou City, a river.

Lin Han leaned on the car, looked at the sparkling water not far away, and nodded secretly.

"This is the water hyacinth ......"

The invasive plants in Yunzhou have been almost cleaned up. But the representative of the most invasive plant - water hyacinth, until today, he did not see it with his own eyes.

I saw that on both sides of the river, a dense green was growing, which was gently undulating with the water waves.

These water hyacinths are covered with broad green leaves on the top of their heads, and underneath are connected to a raised structure that looks like a gourd, and some of them are wearing small purple flowers that look like young chrysanthemums......

Don't look at it looks harmless to humans and animals, but the phoenix eye blue, commonly known as water hyacinth, is one of the top ten pests in the world, and it does endless evil.

In the beginning, water hyacinth was introduced from South America to China as pig feed and widely stocked in rural rivers and ponds in the south.

However, water hyacinth is one of the fastest growing and reproducing aquatic plants in the world, and a single water hyacinth can double its growth area in 6 days, and it can multiply into a population of 600,000 plants in 8 months.

It is known for its reproductive ability, but in China and the lack of corresponding natural enemies, the reproduction of water hyacinth has been more rapid, which can be called lawlessness and once became a typical invasive plant.

So far, water hyacinth has been raging in nearly 20 provinces and cities across the country, Taihu Lake, Huangpu River and other places have been flooded with water hyacinth, and the clean-up work has cost a lot of money, but it has never been able to cure it.

Regarding the actual use of water hyacinth, Lin Han has also done some research before, considering making it into feed and the like.

However, the final conclusion of the investigation was somewhat unsatisfactory.

Theoretically, water hyacinth can indeed be used as pig feed.

But it has a problem that the water content is too large, up to 90%, and if you want to become feed, you have to dry it, otherwise the nutritional value is too low.

If it only needs to be dried, the water hyacinth is not without the talent of feeding pigs.

However, with the increasing water pollution, as an aquatic plant that grows and reproduces at a high rate, water hyacinth can be said to have a very low ability to degrade harmful substances.

The production cost is high, and there are many harmful substances. Therefore, the practical value of water hyacinth can be basically ignored.

Unless you let the "health experts" come out and spread rumors, saying that this thing is aphrodisiac or something...... But Lin Han obviously doesn't look down on this kind of dirtyness, and there are big doubts in the actual operation.

So after a little consideration, he gave up on the idea of investing in water hyacinth.

In fact, if you think about it, since it is characterized as an invasive species, it already shows that it is not very valuable.

If it's like a crayfish, no matter how powerful the invasion is, what's the use of eggs, it's not that it has to be eaten and has to rely on artificial breeding to survive......

Lin Han stopped for a moment, the "anti-green buff" spread out, and the water hyacinth in front of him immediately began to wither and decay from the roots, and the tenacious vitality was like a deflated ball, quickly becoming shriveled......

"Gaia, are there any invasive plants in Yunzhou?"

Gaia said, "It's been cleaned up. ”

Lin Han nodded, and asked again: "How are the invasive plants in Handong Province cleaned up?"

Gaia seemed to think for a moment, and then said: "At present, the invasive plants you have cleaned up account for about 5% of the invasive plants in the province. ”

"It's only 5%, that's so little. ”

To obtain full biological rights, 50% of the invasive plants in Handong Province need to be cleaned up.

Now it's only 5%, which is far from it.

"There are more invasive plants in the Hannam area, so if you want to complete the task as quickly as possible, you can start in the south. ”

Gaia said, "...... Once you've gained full creature clearance, the area of effect will change from a radius of 10 kilometers to a radius of 100 kilometers, increasing the area by a factor of 100. In this way, it will be much more convenient for you to clean up the invasive plants. ”

The high-level biological authority covers a radius of ten kilometers, which translates to an area of more than three hundred square kilometers.

The radius becomes 100 kilometers, and the area is more than 30,000 square kilometers.

Handong Province is only about 100,000 square kilometers, and as long as it obtains full biological permission, it will be possible to take a plane to go around several large cities at that time, and it will be possible to solve it all in two days at most.

This efficiency ...... It seems that it is still important to upgrade.

……

In the conference room of the Municipal Agricultural Bureau, Director Guo sat in the center, holding a speech in his hand and talking eloquently.

“…… To emphasize...... Strengthen...... Seven major policies...... Six Fundamental Points...... Five Principles ......"

A few hours later, a figure suddenly appeared at the door of the conference room and whispered, "Director." ”

Director Guo's expression moved: "Xiao Wang, what's the matter?"

Xiao Wang hurriedly came over and said, "Vientiane just contacted us and said that the invasive plants in Yunzhou City have all been solved. ”

As soon as these words came out, the originally lifeless conference room suddenly became a little lively, and everyone turned their heads and talked about it one after another.

"It's only been a few days, and it's been solved so quickly?"

"Really?"

"Forty million, I guess it's true. ”

Don't talk about other people, even Director Guo himself, at this time, he was also moved: "It was solved so quickly!"

Although the effect of the hollow lotus seed grass cleaning in Nanshui County was very amazing, there was not much news about the cleaning speed.

According to his idea, it would take a month to clean up the invasive plants in a city.

In less than a week, it has been completely resolved. Such a speed was greatly beyond his expectations.

"What's the response down here?"

Xiao Wang said: "Several counties and districts in Qinglin County and Linhai County have been solved early, and there has been some feedback, which seems to be not bad. There's no news from the rest of the place yet, but it should be soon. ”

Director Guo pondered for a while, then put down his speech and said to a middle-aged man beside him: "Wait for the feedback on the cleaning effect below, if there is no problem, let people pay the cleaning fee as soon as possible." ”

"Okay. ”

Director Guo nodded, then picked up the speech again and coughed lightly.

"Ahem, the meeting continues...... Hmm, where did you just go?"

“……”

……

The power of high-level creature permissions is naturally not in doubt. It didn't take long for the feedback from the cleanup of invasive plants in various parts of Yunzhou City to be sent to the Municipal Agricultural Bureau.

All localities praised the clean-up effect of Vientiane, and the city bureau certainly had no objections.

Soon, a total of 40 million yuan was paid to Vientiane.

Although 40 million is not much, it is quite timely for Vientiane, which is currently a little short of funds.

With the 40 million, Lin Han waved his pen and immediately allocated 30 million to Lou Bingcheng. Let him dig up some scientific research backbones, recruit some young people, and speed up the establishment of the second and third laboratories in Vientiane.

The funds are more abundant, and the Vientiane Laboratory has always been mysterious and high-minded, and the establishment plan is going quite smoothly.

A new scientific research organization began to take root in Yunzhou, a 3.5-tier city.

As for Lin Han, he is busy contacting the Provincial Agricultural Bureau, preparing to go further on the road of "Invasive Plant Terminator".
