Song Shan has been a little deaf lately.

Whether it was a farmhouse project or a new medicinal herb project, he didn't ask too much, even the rice and corn harvest, the planting of a new batch of winter wheat, these big and small things, he left them all to the people below to do.

He was working on his own project, a two-hundred-square-meter planting plot at the back of the villa's small greenhouse.

This place was originally a homestead, but there are many homesteads in the village, and they are not so particular, whether it is a planting land or a homestead, as long as it is coordinated with the village, a house can be built.

This is a piece of planting land obtained by Song Shan and the next door neighbor in the village after negotiation, and more than 300 square meters next to it have also been taken down, and the small greenhouse can be expanded to more than one acre or so.

So this piece of planting land is already part of his private small greenhouse.

But now, he needs to experiment with growing something in a normal place, and he doesn't have a greenhouse system.

He's experimenting with planting fast-growing trees.

There are three major fast-growing tree species in the world, eucalyptus, pine, poplar, Song Shan personally, he prefers poplars, so the saplings he chose to experiment with are poplar saplings, and poplars are also the best trees to plant.

It can become a forest in five years.

But this is not enough for Song Shan, he needs to make this time shorter, he needs to plant a forest in the shortest time.

At first, he chose grafting.

Grafted are the branches of the immortal tree.

The immortal tree is now growing bigger and bigger, growing very quickly, it is already half a story high, and it has also grown a lot of branches, this irregular speed makes Song Shan see a different immortal tree.

So he tried grafting some branches onto the poplar saplings.

He wanted to use the hormone-like growth of the undead tree to stimulate the growth of the poplar, but the experiment basically failed.

Poplar saplings do not burst out with the growth rate of an undead tree.

The characteristics of various trees are different, and grafting may also cause counterproductive effects, and if the characteristics of poplars and immortal trees cannot be fused, they will not be able to grow together.

"Even if you use water spirit beads and have a short growth cycle, the growth time of this poplar tree is still not good!"

Song Shan looked at the poplar saplings that had only been planted for a few days and sighed.

More than 200 square meters, he probably planted more than 400 poplar seedlings, and the investment in this area can be regarded as a lot, and it is difficult to say whether it can have an effect.

But in order to fight for the planting project that shocked the whole country, Song Shan felt that he had to fight.

"Water Spirit Beads alone don't seem to be enough!"

Since Shennong Origin Ding ate the Bronze Ding, he still wants to change a little, and spit out the Water Spirit Bead every day, there are as many as two, which has doubled the amount, but Song Shan's projects are too many and he has never been able to take care of them.

And once he took over that project, it was impossible to rely on the Shui Lingzhu, after all, the Shui Lingzhu was a drop in the bucket and difficult to maintain.

"These poplar saplings must be improved!" Song Shan made a big decision, although he is a butterfly, the butterfly effect can change the fate of some people around him, but many things are beyond his reach, and the time left for him by that project is running out.

Song Shan devoted himself to research.

He personally served as the project director, and also invited a lot of professors and added a lot of equipment, in order to develop a unique rapid tree.

Song Zhiqing, as the chief of the company's technical department, was the first to join the research.

"Boss, poplars can suppress the growth cycle, it has been suppressed to the extreme, there is no longer a shorter planting method!" Song Zhiqing was busy for more than a week, and finally found nothing, and said to Song Shan: "Rapid trees have been in China for many years, and it can be regarded as an emerging research, but as far as I know, there are not many research results, after all, tree planting, the growth cycle is the biggest problem, the growth of a tree, at least five or six years, more than a few decades to be effective!"

"I know!"

Song Shan smiled bitterly: "I'm just not very willing, so I have to try!"

He remembers that it seemed like bidding had only started in November.

He still has some time.

Without research results, he does not dare to guarantee that he can compete for the 6 billion afforestation project.

Song Zhiqing didn't say much, since the boss had an order, he also complied, not only transferred some backbones from the technical department, but also used his personal connections to bring in a professor with deep research on afforestation from the Agricultural Institute of Xida University.

Lei Guozhong, who is very old, in his seventies, has retired, he is a lifelong honorary professor of the Agricultural Institute of Xi'an University, and also one of the nominal mentors of Xijing Agricultural Science and Technology Researcher, and is well-known in the agricultural circles of Northwest China.

"Xiao Song, why do you want to improve poplar planting?" Lei Guozhong asked Song Shan.

"Me?"

Song Shan thought for a while and replied: "I actually saw the Yangtze River flood, I only had an idea, the phenomenon of indiscriminate felling, in the eyes of the country, this time the Yangtze River flood is actually nature's biggest accusation against human beings, environmental protection is urgent, the country will not pay attention to this, and planting trees, after all, is a long time, deep effort, if there can be more easy to plant fast trees, maybe change some of the environment, of course, I hope more, can make money!"

"It's very good to be young, to have this responsibility for the environment, and ideas!" Lei Guozhong praised, but also poured a basin of cold water on Song Shan, and said: "Poplar is a fast-growing tree, I have tried to graft many times over the past few decades, and I am alive to change the soil composition, the growth environment, and hope to stimulate growth, but because his original growth cycle is shorter than that of ordinary trees, it is already difficult to be short, the old man advises you, don't waste too much in this regard, it is not fruitful!"

"I haven't tried, I don't believe it!"

Song Shan said a little stubbornly.

"You kid, it seems like when I was young!" Lei Guozhong looked at Song Shan's stubborn head and smiled slightly bitterly: "That's it, old man, I'm old, and I can't help you anything, but there are some materials in the family, which are the results of my research over the years, you can learn from it!"

"Thank you, Elder Lei!"

Song Shan hurriedly thanked him, that was the result of Lei Guozhong's research for many years at the Western University Agricultural Institute, even if their research was not fruitful, this process was also worth learning from Song Shan.

"Don't thank me!" Lei Guozhong sighed and said: "I also hope that domestic agricultural research can progress, because there are too many people hiding too much smuggling now, which is not conducive to the progress of research, the development of science and technology, including agriculture, but many people often just can't see the development of agriculture!"

The next day, Song Shan got this information, a copy, I can't say that, it's just a room, although there are a lot of ways to store information with computers in these years, but it is not popular, most of this information is handwritten, there are seven big boxes.

This is incomparably precious to Song Shan.

"Lei Lao, don't worry, I will never live up to your expectations!"

Song Shan assured.

His research on the Rapid Tree began to increase continuously.

He has a killer feature.

That's the Water Spirit Bead.

The composition of the water spirit bead, he didn't dare to analyze it, but there were many guesses, although he didn't have many water spirit beads, but if he could borrow the water spirit beads, and then use some technology to change the essence of the sapling, it would definitely be a great thing for planting.

That's what he's doing.

So this research, the core research, he basically completed it alone, and he didn't want to expose the water spirit beads.
