In the afternoon of the same day, Song Shuqing came to the near Nanshui County Agricultural Bureau and placed some items in a house he had rented in advance.

Then, while the Agricultural Bureau had not yet got off work, he put the computer, documents, etc. in his office.

"Dongdong."

Just as he was busy in the office, a knock on the door came.

Song Shuqing turned around and looked at it, hurriedly greeted him and said with a smile: "Director Dong."

The visitor was Dong Xiao, the former deputy director of the Nanshui County Agricultural Bureau and the current director.

Dong Xiao nodded and smiled and said, "Xiao Song, from today on you, you have been a member of the Agricultural Bureau. Your previous achievements in Tianhu Village are obvious to all. I believe you will definitely make new achievements here..."

"Nanshui County has many rural areas and a wide range of agricultural foundations, so do it well."

After saying some encouragement, Dong Xiao was about to leave. Song Shuqing hurriedly said, "Director Dong, I have something to tell you."

"What's up?"

"A few days ago, Mr. Lin of Vientiane Technology said that he would prepare to clean up invasive plants. The first place to clean up is our Nanshui County." Song Shuqing said.

"So, regarding invasive plants, I want to set up a special project to prepare for the invasive plants in the county."

Dong Xiao pondered for a moment: "The prevention and control of invasive plants is carried out every year in the county."

"And, since there are many rural areas in Nanshui County, most of the invasive plants will be handled by local farmers themselves. Apart from specific public waters, the harm is not particularly great."

Song Shuqing said: "For invasive plants, Vientiane has launched its first management. They have guaranteed that Vientiane's governance for Nanshui County will be completely free."

Dong Xiao was stunned: "Free?"

Song Shuqing nodded: "And as far as I know, the governance methods of all things must be more lasting. If there are no new invasive plants, it will almost be equivalent to permanent healing."

"So powerful!" Dong Xiao showed a moving look.

Unlike Song Shuqing, he can be said to have done it bit by bit from the grassroots level of the Agricultural Bureau. He has a very clear understanding of the invasive plants.

If everything could really remove invasive plants so thoroughly, it would be a great blessing for agriculture and forestry, and its influence was even comparable to hybrid rice.

Dong Xiao thought for a while, then said: "The most important invasive plants in Nanshui County are 'hollow lotus seed grass', which are distributed in paddy fields and rivers..."

Hollow lotus seed grass, commonly known as "water peanut", is the first batch of foreign invasive species in China.

It is a kind of aquatic and semi-aquatic weed, native to Brazil, and was first introduced to China from North America in the early twentieth century.

In the 1960s, my country tried to plant hollow lotus seed grass for animal feed.

But later, people found that it contained some toxicity and had a poor taste. Pigs, cattle and other livestock do not like to eat it and are not suitable for feed, so they gave up.

Although artificial planting has been abandoned, hollow lotus seed grass has spread in China, causing great harm.

This thing has a strong vitality, and is not afraid of drought or flooding. As long as there is a small section in the field, it will grow wildly and will be born for generations.

Its vitality is so tenacious that after eating pigs and cows, the grass feast in the feces can also grow grass.

Hollow lotus seed grass growing in farmland robs the crops of sunlight, moisture, fertilizer and growth space, and eventually leads to severe yield reductions.

Hollow lotus seed grass growing on river waterways and by lakes can quickly cover the water surface, affect other aquatic plants, and hinder drainage, water transportation and aquaculture.

If the grass rots and dissolves in the water, it will also produce toxic substances, pollute water quality and poison aquatic crops.

In addition, the large-scale reproduction of hollow lotus seed grass will also provide breeding space for mosquitoes and flies, spreading diseases...

Although this thing has certain practical value, such as clinical medicine, since the demand is not large, after salvaging, it can only be treated as organic waste.

...

"Hollow lotus seed grass?"

A few days later, Lin Han obtained a document on hollow lotus seed grass in Song Shuqing's office and related documents on Wanxiang's helping the Agriculture Bureau to remove hollow lotus seed grass.

Song Shuqing said slowly: "The invasive plant in Nanshui County, that is, this hollow lotus seed grass... has been marked on the map, take a look."

The shape of Nanshui County is about a square shape, with an area of ​​1,300 square kilometers, and the overall shape is still regular.

Lin Han gestured according to the map and thought that as long as he stayed in the six main distribution areas for a while and released the "anti-green buff" targeting invasive plants, the hollow lotus seed grass in the county should completely die, and no one left.

Song Shuqing couldn't help asking: "Hey, can you tell me, what are your methods of handling it?"

Lin Han smiled but said nothing, which made him even more curious.

"Just talk about the basic principles?"

Lin Han pondered like that and said, "The basic principle, I guess it should be energy conservation."

"Energy conservation...why don't you say it is the conservation of mass and energy?"

Lin Han smiled and said, "You should understand biology best. I just got the B exam in biology, so how could I know so much?"

Song Shuqing waved his hand: "Forget it, it has nothing to do with me anyway. I really don't understand. Where did you get so many black technology?"

Lin Han asked: "By the way, what is the annual investment in cleaning the hollow lotus seed grass in Nanshui County before?"

Song Shuqing picked up the documents next to him, and said, "The distribution of hollow lotus seed grass is mainly in farmland areas and a small number of rivers. Since farmers usually clean up by themselves, the cleaning cost is mainly in river management."

"After all parties' expenses, the annual cost is about 2.2 million yuan. In other words, Vientiane's free governance has saved at least more than 2 million yuan for Nanshui County."

More than two million...

Lin Han suddenly felt a little distressed and saved more than two million for free.

Forget it, just think it is to support the construction of a new socialist countryside. Nanshui County is at least an important part of the layout plan of the world.

Lin Han and Song Shuqing chatted for a while, then left the Agricultural Bureau and sat straight on their Maybach.

Tell the mark on the map to the driver: "Go to these places."

"Drive."
