For You To Go To College, You Go Home To Farm After Graduation?

Dingyuan City.

As soon as the sandstorm crossed the border, Mayor Han Muqing asked the driver to take her all the way to the Holy Land Ranch.

Now the Holy Land Ranch is the economic pillar of Dingyuan City.

The disaster situation of Holy Land Ranch directly determines the disaster situation of Dingyuan City.

After Han Muqing arrived at the Holy Land Ranch.

Heart - sank.

a week ago.

She had been to the Holy Land Ranch.

At that time, the winter snow had just melted.

Earth recovers.

The whole pasture was green, and the cattle and sheep happily ate the pasture.

There is life everywhere.

but now.

The grass was blown by the fine sand and gravel, scarred.

Many pastures were lifted up by the dust storm and rolled up together with gravel.

The staff on the ranch are busy working on the aftermath.

Too busy to even entertain her.

Xiao Han sighed.

It's really a lot of calculations, ignoring the sandstorms in the northwest region in spring.

In March, the frequency of sandstorms is actually not high.

Only once or twice a month at most.

But in the following April and May, there was a sandstorm almost every few days.

There was a large 16 sandstorm in more than 10 days.

so down.

Farm operations will be greatly affected.

Even half dead.

"How to do?"

Han Muqing's eyes were confused.

There was nothing she could do.

The problem of sand and dust storms has not been resolved despite the efforts of the entire country for decades.

What can a small Dingyuan city do?

Han Muqing returned to the city government with a heavy face.

Although the city government's funds are very tight.

But she still set aside part of the money for emergency relief.

Northwest Desert.

Liu Fei is a staff member of Ant Forest.

He is an environmentalist.

Love nature, love the big forest.

When Ant Forest started to fix sand and wind in the northwest, he took the initiative to apply.

It has been 10 years so far.

In the past 10 years, Liu Fei has planted more than 4 million Haloxylon sylvestris, Pinus sylvestris and Salix.

Look around.

An entire desert is his tree.

but.

Liu Fei was not proud.

Because 4 million trees are just a drop in the bucket for the vast desert in the northwest.

It can only play the role of windbreak and sand fixation in a small area.

It doesn't affect the overall situation.

Dust storms occur every year.

Just entering March this year, there was a once-in-a-decade dust storm.

Liu Fei is sometimes confused.

His power alone is too small.

The power of a group of people is still very small in the face of nature.

in the Northwest Desert.

There are more than 10,000 people like him.

But they have planted trees for so many years, planting tens of millions of Haloxylon sylvestris, Pinus sylvestris and Salix.

Due to lack of water and drought, high temperature and heat, the natural environment with great temperature difference.

No more than 10 million trees can survive.

Some of them were harvested secretly.

Because trees such as Haloxylon syringae have certain economic value and medicinal value.

Some thieves, conscienceless, do not care about the ecological value of these trees.

Stealing for temporary gain.

"Maybe it will take another 100 years to be effective."

Liu Fei sighed.

Continue planting Haloxylon.

The technology of planting trees has been greatly improved.

For example, the "minimally invasive airflow tree planting method" is often used

0

The jet of water jetted from a pressurized water gun punches small holes a few centimeters in diameter and one meter deep in the sand.

Then quickly plant the saplings, dig holes, plant trees, backfill, and water, all in one go.

The water flow instantly hits the hole to form a water-retaining and anti-seepage layer, and only 3 liters of water is needed to plant each tree.

Another method is the "auger tree planting method", also known as "dry planting".

Using micro-power to drive the auger to drill holes, insert saplings, and then compact the sand, it is also fast and efficient.

use of these methods.

This greatly improves the efficiency of desert tree planting.

The survival rate was also increased by 50%.

But plant trees anyway.

All need some moisture.

Will these trees survive in the later stage?

It's also up to God.

If there is no precipitation for a long time.

Many trees will die.

After all, even drought-tolerant plants cannot grow without water.

Jiangshui City, Holy Land Seed Industry Office.

Li Xu received the disaster report from Holy Land Animal Husbandry immediately.

Han Muqing also called him personally.

Han Muqing was just complaining.

It didn't mean to ask Li Xu to find a way.

Because in Han Muqing's mind,

The problem of sandstorms cannot be solved by one person at all.

hang up the phone.

Li Xu's face was ugly.

"I ignored the dust storm! 35

When he simulated the super alfalfa, he only took into account the strong wind, but not the sandstorm.

But even taking into account the dust storm.

Super alfalfa is not afraid of dust storms.

But the cattle and sheep on the pasture are still affected by the dust storm.

So want to solve this problem.

Dust storms must be addressed.

"Sandstorm, you provoke me, you are dead."

Li Xu gritted his teeth.

Ever since Seed Simulator.

It was the first time he was so passive.

In the past, he took the initiative to solve problems.

Now the sandstorm has bullied him.

How to endure?

Li Xu quickly searched for the corresponding method.

The reason for the increasingly serious sandstorm in China is mainly due to the unreasonable development of land and unreasonable farming and grazing.

A large amount of land in the northwest has been reclaimed, grasslands have been overgrazed, and natural vegetation has been artificially destroyed.

A large amount of bare transported land is formed, which provides a large amount of sand and dust sources for the occurrence of sandstorms.

But in recent years, with the construction of returning farmland to forest, returning farmland to grazing and the construction of northwest shelterbelt, this problem has been basically solved.

But another reason, the desert in the northwest, is the biggest source of dust storms.

To control the desert, the simplest and most fundamental way is to fix the sand and dust.

How to fix?

Nature is planting trees.

This is Li Xu's strength.

Many plants that can survive in the desert flashed in Li Xu's mind.

In the end, his eyes fell on the Haloxylon.

compared to other desert plants.

Haloxylon has many advantages.

First, its seeds are the fastest germinating seeds in the world.

Just give it a little water and it will sprout and grow very quickly.

Secondly, in the process of its growth and development, Haloxylon chinensis has always maintained the preferential distribution of biomass underground, that is, preferential root growth.

This is an important survival strategy for Haloxylon:

Put photosynthetic products into the ground, on the one hand, grow and develop more water-absorbing roots in moist soil patches or soil layers to obtain water and maintain survival;

On the other hand, the taproot that grows downwards can reach a depth of more than ten meters underground and reach the groundwater level. By drawing groundwater, it can avoid summer atmospheric and shallow soil drought and ensure the survival of plants.

The most important thing is that the special leafless structure of the canopy of Haloxylon chinensis can realize the drainage of micro-precipitation, and form a preferential flow along the trunk and root system, and finally enter the soil and store in the soil in the root zone, so that the root system can effectively absorb and utilize.

Based on this self-harvesting function, Haloxylon ammonides can convert about one millimeter of precipitation into effective precipitation that plants can use.

Haloxylon syringae has a strong ability of windbreak and sand fixation, excellent stress resistance and easy to breed and plant.

Therefore, it is known as the "protector of desert ecology".

The canopy of the adult Haloxylon ammonites is 3 to 5 meters, and the root system is very developed.

"I want to simulate a new species of Haloxylon."

"Hawthorn trees that survive without watering. 35

"The root system is more than ten times that of existing varieties, which can fix more deserts.

Li Xu's eyes were bright.

"Sandstorm, I want you to disappear on the land of China!
