Zhang Chun just grinned and followed behind the experts of the Yellow Control Committee. The ones who listened most carefully were Xu Benshan and Zen Master Zhenxu.

On the periphery, Liu Hui suddenly helped a stranger to the bottom of the tree, and several guards took the person away, but it was obvious that the person had no vital features. This action is done very secretly, as if it is just helping a person who is unwell to rest.

Zhang Chun frowned, because no assassin had ever been so close to Zhang Chun. There are many experts from outside the committee and even some foreign experts. The personnel is complex, and the attaché is even more complex. Darkmoon was a little overwhelmed.

However, Zhang Chun actually found that it was Shui Ling who hugged Luo Niu'er and greeted that person first, creating conditions for Liu Hui.

Liu Hui's short-range speed is almost like teleportation. The movements of the hands behind the close are dazzlingly fast. But there was no doubt that she was going straight to her heart, she couldn't see it, but she could hear it.

Zhang Chun saw that the pistol that had been pulled out of the assassin's body was quickly picked up by Shui Ling and hidden in his arms.

Luo Niu'er is indeed a piece of material, and she was not surprised at all at a young age.

Very few people have noticed these changes.

Even Xu Benshan and Zen Master Zhenxu didn't explain and were attracted, and they didn't care about the outside world at all.

The reason why Zhang Chun found out was because he found that Lizhen's attention had also shifted to the conversation. The two are too familiar, and the roles of the two have always been reversed. So Zhang Chun naturally turned to the role of protection.

But the Assassin was too far away, and he was well hidden. There is no difference with a large number of attachés. If Zhang Chun finds out. I'm afraid it will be a little later than Liu Hui and them, and I will have to wait until the gun is raised. Even if Zhang Chun and Lizhi were sure to dodge before raising their guns and shooting. But with so many people, it's hard to hide. There are always accidental injuries.

When she came back to her senses, sweat broke out on her forehead.

Zhang Chun pinched her palm, and Lizhi leaned her head against Zhang Chun's shoulder.

Xu Benshan noticed the small movements of the two, and thought that the little couple was showing affection, so he looked up at the two of them charity and smiled: "The cycle of heavenly principles, I can't imagine that it is not a lie." ”

Zhang Chun smiled: "Of course not. ”

The governance of the Yellow River was the "stagnation of the river" in ancient times. Because the Yellow River flowed everywhere downstream at that time, legend has it that it was divided into nine rivers and entered the sea separately. To the "wide embankment" in the Warring States Period, from the "Jia Rang Sance" in the Han Dynasty to the "construction of the Yao Dike" in the Song Dynasty, it was basically the governance of the river itself. There is little mention of sand damage. On the one hand, the vegetation at that time had not been destroyed, and the sand damage was not too serious.

Especially in the Dayu era recorded in Shangshu, there was little change. But then agriculture flourished, and with the large-scale reclamation of the Yellow River Valley. The Yellow River began to be disobedient. From the Han Dynasty. The Yellow River keeps diverting its course. Sometimes it leads to the Yellow Sea, sometimes to the Bohai Sea. The biggest reason is the siltation of the river.

The situation in the Ming Dynasty became more and more serious, and the strategies of "attacking sand with water" proposed by Pan Jitao at the end of the Ming Dynasty and "attacking sand with water" proposed by Jin Fu and Chen Huang in the Qing Dynasty have achieved certain results. Pan Jitao also put forward the idea of "accumulating and clearing and brushing yellow". Jin Fu and Chen Huang of the Qing Dynasty basically inherited Pan Jitao's idea of controlling the Yellow River, built high dikes, restrained floods, and attacked sand with water, thus enhancing the flood control capacity of the lower reaches of the Yellow River.

But little has been done to address the source of the Yellow River's sediment. On the contrary, the damage to vegetation due to reclamation is becoming more and more serious. As a result, the flooding of the Yellow River was out of control.

Zhang Chun proposed that in order to control the Yellow River, it is necessary to first control the upper reaches of the Yellow River. It is to govern from the source. This is refreshing for the people of the Yellow Control Committee. What's more, this strategy has been in place for more than three years. It's just that they didn't think about the governance of the upper reaches of the Yellow River. It actually contains a completely new agricultural idea.

And realistically, the effect is still very good.

"Isn't it troublesome for you to plant fruit trees like this?"

Some of the steeper slopes, the orchards that the forest farms call them, are almost indistinguishable from the forest, with dozens of fruit trees, nuts and fruits mixed together. Although each has its own territory. But this kind of planting method, everyone has really never seen it.

"It depends on how you look at it, the season for all kinds of fruits to ripen is certain, and it's not too troublesome."

The number of citrus, persimmons, apples, jujubes, and walnuts that ripen in September is still very large. Workers at the forest farm carried baskets of fruit from the mountains and piled them up in the sorting and packing workshops of the forest farm. There are also some nuts that look absolutely inedible. Such as acorns, pine nuts, holly nuts and so on.

The sheer number and variety of varieties astonished these experts.

And this is still the result of taking two and leaving three. The people at the forest farm say that there are many birds and animals in the forest that need these fruits for wintering. So take two and keep three as a rule, of course, human beings take the best.

In addition to these fruits, there are also various mushrooms, eggs, and meat. The scale of a forest farm is very large. The division of labor in the forest farm is also very fine. From managing the mountain forest to picking, to sorting and packaging, the forest farm has a special railway, a freight yard and a station.

"These are still mainly produced by mountain forests, and there are very few fruits introduced artificially. For example, this persimmon can only be used to make fructose now, and the pit is too large. Of course, the pits are also useful. When we manage mountains and forests, we will use grafting methods to improve them. It will be much better in a few years. ”

"Forest management is not just about utilization." Lizhi couldn't help but remind.

The director of the forest farm said with a smile: "Sir, in recent years, we have introduced some foreign tree species, such as this pine nut, the local pine nut is not so big. We will not forget the nature and evolution of forests. The forests of Shaanxi have just begun, and there are very few forests to talk about, just talking about the level of tree canopy. All are secondary forests and large-scale planted forests. Because there are very few big trees. The reason we were able to harvest so much fruit was because they were so short. ”

"In the north, unlike in the south, these trees grow a few months shorter and grow slowly. But on the contrary, the fruit is set earlier. The quality of the fruit is also good. Of course, there have been some subtle changes in the past few years. With the increase of understory plants, soil fertility and moisture improved. The growth of trees is accelerating. Then there are large areas of forest, which leads to increased transpiration. Rainfall in Shaanxi is increasing. As trees grow faster, the canopy hierarchy increases. Of course, it becomes more difficult for us to pick. ”

Zhang Chun nodded and said, "Don't rush for quick success." Don't just look at the immediate benefits, or you will suffer. The current forest is not called a forest, but a forest. Your output now is not much, but less. The output of such a thick forest and such a thick forest is completely different. ”

Zhang Chun tested the thickness of the forest canopy with his hands.

The forest farm also uses biogas to generate electricity, and many of the residues from the processed fruits go into the biogas digesters, and thanks to the restoration of the forests, some farmland in the mountains and at the bottom of the ditch actually grows rice. The water is pumped from the Yellow River to the ditch and then flows over. A worker is tearing down sprinkler pipes in the woods because their mission has been accomplished. And winter is coming, and the pipes will freeze.

"There are a lot of workers in the forest farm." Sun Chuanfang asked.

"Quite a few, this year, the forestry trade union will be separated from the agricultural trade union, which can account for about 30 percent of the original agricultural trade union."

Wu Peifu said in surprise: "So many people? ”

The director of the forest farm smiled: "Because we have a large land area." All the mountains, all the sides of the road, we took care of. In terms of the amount of land under management per capita, that's not a lot at all. ”

"With so many people, is there enough food to eat?"

Wu Peifu asked Zhang Chun.

Zhang Chun smiled: "The forest farm also has its own farmland, and they provide us with a lot of starch, meat, and fruits and dried fruits. At present, the dietary structure of the common people, the proportion of staple food has been reduced. It's just that it takes a process, and Shaanxi has just gotten rid of grain imports. Gansu, Suiyuan, including Yinshan and Altai regions all need to subsidize grain. Fortunately, in recent years, we have imported a large amount of low-cost grain. to be able to support. ”

Zhang Chun said that the support is the migration to these areas one after another. In two years, more than two million people have migrated to the region. There are not many immigrants in Hubei anymore, because the population of Hubei cannot be less than that. Among the immigrants, Sichuan, Henan and Hunan are the majority. Jiangxi's population itself is not too large.

Shaanxi's population is also increasing, and it now includes Suiyuan, south of the Yellow River, and all of Ningxia. From more than 9 million to 14 million. And in 1831 almost all of these additions were imported food. It was not until the summer grain harvest in 1932 that it was flattened.

Gansu's population has grown from less than 6 million to 7 million. And this rate is increasing, because the population of Qilian Mountain and Dunhuang is increasing rapidly.

The population of Suiyuan did not increase much, mainly in Baotou and Yinshan, with an increase of nearly 500,000 people, reaching nearly 3 million. Altai was completely robbed, where there was no settled population and now it has reached almost 300,000 people. And that's not counting the 60,000 men of the two armies.

This great migration of people took place unconsciously, especially after the improvement of the transportation system, and this movement did not seem to cause much fluctuation among people.

Sichuan has a population of about 40 million, and there is no statistics on Ganzi Aba. There are nearly 30 million people in Henan

There are only more than 18 million people in Hubei. Hunan has a larger population, more than 26 million, and Jiangxi is even less than Hubei, more than 13 million.

Shandong and Longhai have not yet had time to count

The total population of the entire control area is about 200 million. And the army, counting the military-industrial complex, is only a million people. This is also the reason why Zhang Chun dared to let several other companies disarm in the same way as himself. The combat units, not counting the air force and navy, have only ten armies and one independent division, and more than 300,000 people.

Of course, this does not include the police, reservists and militia. (To be continued......)
