The Three-Body Problem: The Most Competent Wallfacer of All Time

Chapter 114 Investigation
Jiang Yu and Jiang Shiliu drove back to Beijing's airport first, met with the experts of the "Green Green Project" project, and then the group of people took a plane to the south together.

Jiang Yu was a little strange: "Aren't we going to see the current situation of desert agriculture? Why go to the south first?"

An expert named Qi Guanglu explained: "We have discussed in the past few days, and I feel that there are only two projects that meet your requirements, one of which is to compare the southern land with the desertified land.

"So let's go and see first, the varieties that were originally bred in the south."

Jiang Yu nodded, and understood Qi Guanglu's meaning. This was a remedial lesson for him, a layman.

When Jiang Yu arrived in Guangdong, he was a little surprised when he saw the grass growing neatly and more than seven meters high.

Seven meters has reached the height of a three-story building, and Jiang Yu has to look up to see the top of the grass.

Qi Guanglu explained: "This is the giant fungus we imported from Africa in the 80s.

"After years of cultivation, African countries are now importing from us."

Jiang Yu had seen grass several meters high before, but such neat patches of grass that were as tall as the surrounding trees were still very spectacular.

Qi Guanglu continued: "The name of giant fungus was given by my teacher, and he planted this grass all over the country!
"Take this pasture base as an example. Because of the suitable climate, proper fertilizer and water, giant fungus grass can be harvested every [-] to [-] days."

Only then did Jiang Yu come to his senses: "Can this kind of grass be grown in the desert?"

"Yes," Qi Guanglu said, "because it grows very tall, and it also has the effect of sand prevention and sand fixation.

"Gianjuncao has been planted in Xinjiang, Inner Mongolia and other places, and there are new varieties that can be planted in saline-alkali land, and have the effect of nitrogen fixation, which can improve the fertility of the land.

"Bringing you here is to let you experience the impact of climate on vegetation.

"Please take a walk on the ridges of the fields to feel the excellent growth environment created by the rainwater in the south."

Jiang Yu nodded, and led Jiang Shiliu to walk on the field ridge, looking at the sky above his head: "Have you ever seen grass that is so tall and so neatly grown?"

Jiang Shiliu said, "I haven't seen it before."

"I just found out today that I don't understand agriculture at all!" Jiang Yu said with emotion: "It's just a good time to take advantage of this inspection to make up for myself."

After wandering around this pasture for an hour or two, Jiang Yu and others immediately flew to the Kashgar area of ​​Xinjiang.

Early the next morning, Qi Guanglu took Jiang Yu to the local giant fungus planting area.

From a long distance, you can see a piece of green "giant fungus grass" in the sandy soil, but it is much shorter than the "giant fungus grass" in Guangdong.

Qi Guanglu explained from the side: "This piece of 'Giant Juncao in the Sand Land' covers nearly [-] acres, and has changed the surrounding ecological circle to a great extent.

"The giant fungus grass here is only two to two and a half meters long, but in the northern region, it is already considered a tall grass.

"Look over there, it's a saltwater lake, it's hard for common crops to grow by the lake, or it can't be irrigated with the water in the lake.

"This variety of giant fungus grass is designed for such an environment, because it is irrigated with water, so it can grow so tall.

"However, due to the limitation of water resources, the giant fungus grass here can only be harvested for two seasons at most every year."

Jiang Yu looked at the giant fungus grass floating in the wind around him, and felt that the heat in the desert had dissipated a lot.

He asked again: "What will happen to the giant fungus grass in the desert area where water is difficult to get?"

Qi Guanglu took a deep breath before saying, "You will be able to see it tomorrow."

So after another half a day of running around, the group came to a Gobi Desert.

A gust of wind blows, yellow sand is everywhere, and if you are not careful, you will eat a mouthful of sand.

On the other side of the dunes, there are rows of greenish-yellow grass that is about the same color as the sand.

They were only as high as knees, and if some leaves were not green, Jiang Yu would have thought they were dead.

Through the leaves of these grasses, Jiang Yu can tell that this is also giant fungus grass.

Compared with the Jujuncao in Guangdong, the Jujuncao here seems to come from Lilliputian.

Qi Guanglu said: "It is very inconvenient to get water here, even though the roots can penetrate several meters underground, this special species of giant fungus grows so poorly.

"If water is diverted from other places for irrigation, the cost is too high and the benefits are too small, so there is only this experimental field, which cannot be scaled at all."

Qi Guanglu paused and said: "The reason why the desert is a forbidden zone for life is because it is extremely short of water and is not suitable for the growth of any vegetation."

Jiang Yu squatted next to the short "giant fungus grass" for a long time without saying a word. He lamented that it was really interlaced like a mountain. He realized before that he thought too simple of desert agriculture.

I didn't expect it to be too simple, it was simply too naive!

Even the tenacious grass grows so listlessly, let alone a crop.

After a brief loss, Jiang Yu cheered up again. If it was so easy to achieve his goal, he wouldn't need to borrow the power of the Wallfacer.

He quickly controlled his depression, strolled around, and followed the experts to a desert test field in Inner Mongolia.

It was already a day after arriving at the test field, and still far away, Jiang Yu saw that the test field was composed of regular green circles.

Explaining to Jiang Yu was another expert named Zhang Yang.

Pointing to the circles on the ground, he explained: "In the sand here, we have mixed a special adhesive.

"The binder allows the sand to hold together like soil, effectively retaining water.

"Especially in deserts, irrigation is the biggest cost. This invention can effectively reduce the cost of irrigation for desert crops."

Before arriving at the experimental field, Jiang Yu found that the wheat was grown here, and the ears of wheat were only two-thirds the size of his hometown, and they were not very full.

However, there are already harvesters harvesting in the distance.

Jiang Yu asked: "Now the ears of wheat are still green, so they were harvested a little earlier?"

Zhang Yang explained: "The sunshine hours here are long, and it will be too late to harvest after the ears of wheat turn yellow. At that time, many grains of wheat will fall to the ground."

Jiang Yu nodded, looking at the round wheat fields, this may not be a new way.

He asked Zhang Yang: "Is that kind of adhesive expensive?"

"It's not mass-produced yet, and it's not cheap." Zhang Yang replied: "Even if mass-produced, the cost of wheat here is three to four times higher than the cost of wheat planted in ordinary land.

"And the harvest is less than two-thirds of the normal land, completely unable to make ends meet.

"So this project is still only in the experimental stage, and there is still a long way to go before large-scale promotion."

Looking at the green wheat fields, Jiang Yu seemed to feel the tenacity of life.

Then, he gradually had some ideas in his mind.

　Thanks to [Trismegistus] for the 1500 point reward.

　　Ask for a monthly ticket, ask for a recommendation ticket.
