People come and go in Chengfu, and they are in a hurry to treat the funeral at night, many people come to comfort a few words and leave in a hurry because of something, and some people are entertained to rest or eat in the guest rooms of Chengfu.

The time is not early, Mi Huang and Pan Taishi respectively worshiped Cheng Dechen and prepared to leave together, Zhou Jinghua glanced at Cheng Jia, who was going to send them out in person, and looked at Yue Jiao with a chuckle, the eyes were self-evident, the husband and wife were a little embarrassed, looked at each other and smiled, and hurriedly followed the three of them after worshipping.

Cheng Qingqing had long paid attention to Zhou Jinghua's arrival, and when she saw her smile meaningfully, her eyes fell on her second brother and daughter, and she couldn't help frowning slightly, and whispered to Chen Huang, "Chen Huang, my stomach is uncomfortable, leave for a while." "Just excuse yourself to urinate.

Cheng Jia sent them all the way out of the door, and before the three of them went out of the gate, a figure led a thin horse out of the dark alley opposite Chengfu.

Cheng Jia was slightly stunned when he saw the visitor.

"Su Cong, why are you here?"

"My lord, because of the matter in the eastern suburbs, as soon as the heavy rain stopped, the villain entered the city, and in order to wait for the adults to come back, he has been living in the old house in the city. But today I heard that my father had passed away, so I was preparing to go back to the eastern suburbs. ”

Su Cong, who was dressed in a dark scholar's robe and a square scarf on his head, replied.

When Chu people value filial piety, so at this time, Su Cong was about to go back when he heard the news of Cheng Dechen's death at the first time, and he didn't want to make Cheng Jia's reputation lose because of the incident in the eastern suburbs, but he didn't expect to meet him who was going out to see off guests.

"Is there an accident in the eastern suburbs?"

Cheng Jia stood on the door and grabbed him and asked.

Although he specially selected the high ground for land reclamation at the beginning, and even before the flood came, he had already deployed the flood control work in the eastern suburbs in advance, and ordered people to dig drainage ditches and artificial lakes in the morning, but it rained heavily for several days, and it is difficult to say that this ancient greenhouse can completely resist wind and rain like modern glass and sunlight greenhouses.

"Don't worry, right-handed. All the new fields we have reclaimed have ditches, flood lakes, and greenhouses to shelter, the rice is okay, it likes water, but it has been flooded for several days and there is some hunger (poor harvest in farming), but these are much better than in previous years, in previous years, there was no harvest after the flood, but some green cabbage, sunflower, weed (soybean leaves), shallots, onions, leeks, reeds (radish) ...... Because some of them began to rot after the heavy rain, we tried a lot of ways, but we couldn't save them, and the hotter the weather, the more serious the rot became, so I went to Beijing to ask for a meeting. ”

Su Congyi replied one by one, he came to see Cheng Jia because of this matter, to see if he had any way to remedy it, but he didn't want to wait for a few days to wait for the news of the funeral in the Cheng family, and then he told Cheng Jia not to worry, "But it doesn't matter, as long as there is food this year, I will be fine this winter without vegetables and fruits." ”

Cheng Jia nodded.

Indeed, as long as there is food, you can survive the winter.

In this way, at least half of the year's hard work has not been in vain.

After listening to them, Mi Huang was also a little settled in his heart.

But she really wants to follow to see what this greenhouse in the eastern suburbs looks like, and she has always heard that Cheng Jia is in charge of the eastern suburbs to open up wasteland, and the effect is good, but I don't know how good it is.

Even Pan Chong, who was standing on the side, listened to what the two of them said, and asked curiously, "Zikong, what is this greenhouse? Why has the teacher never heard of it, and how can this greenhouse be used to protect rice from floods?"

Mi Huang also looked at Cheng Jia curiously, he had never had a chance to ask in the East Palace before.

"Yes, I've always wanted to ask this question, and how do you grow peaches in the winter?"

"The greenhouse is a kind of canopy made of bamboo woven by Ah Nian to keep warm, windproof and rainproof, but the greenhouse cannot guarantee the increase in the yield of rice and various crops. If we want to really improve agriculture, we need to learn from the experience of Emperor Yu in the north to control the water, and first control the rivers and rivers of Chu in the south of our country to ensure that the wind and rain are smooth, and with enough rain, sunlight and land, the land can naturally grow excellent crops. ”

Just as modern times learn from the successful experience of foreign countries, Cheng Jia used the experience of water control in the north as an argument to explain that the root cause of the low level of agriculture in Chu was that the rivers were chaotic and not controlled.

And because the glass has not been developed in this era, even if the plastic film greenhouse is basically impossible to promote, he originally wanted to use the tung oil cloth for making umbrellas, but he thought that the production cost of oil and cloth is too high, even if it is promoted, most of the civilians and even slaves can not afford to use it at all, or can only monopolize in the hands of the strong and nobles, so it is changed to use the bamboo products made of the cloth, made into a bamboo shed with holes, breathable and light-transmitting, which can shelter from the wind and rain and even prevent insects, so that it can be made of local materials, and it is easy to repair.

And the greenhouse can not completely guarantee the increase of rice yield, this is just for the follow-up promotion of planting two seasons of rice preparation, two seasons of rice rotation so as to ensure that the yield can be improved, even if the two rounds are very few, but also stronger than one round, and if it is other people who cross will definitely say, why don't you engage in hybrid rice?

High yield, good efficiency, disease resistance.

That was when he must have never been to the Spring and Autumn period, and he did not know that natural disasters and floods and the fatal blow of drought to crops were not at all.

Although he is not an agronomic, but as a rural baby, although hybrid rice is resistant to insect pests, no matter how powerful it is, when the flood comes, the drought will be several months, can it resist it?

Apparently not.

It still needs the cooperation of the local environment.

This is a hard indicator, and if the hard conditions are not up to standard, no matter how much he tosses, it is useless.

Moreover, the rise of the Qin State in later generations was also related to the construction of the Zheng State Canal, but the Zheng State Canal was built too late, and the early stage mainly relied on the reform of the well field system to urge the people to pay grain to support the food supply problem of the Seven Kingdoms for hegemony.

Of course, some people will say that he can make some inventions, to be honest, a person who does not even have enough to eat, all kinds of resources are scarce, the wilderness everywhere is in urgent need of development, even the technology of smelting copper is just stable, copper mines are not easy to find, and then even through war to plunder the survival resources of other countries to make up for their own country's times, you let the people and even the upper ruling class have the leisure to invent.

It's okay to play, but it's not the main business.

Therefore, the ruling class of the Spring and Autumn period was only concerned with things related to land reclamation, war, and hegemony.

It can bring more arable land and people to the various lord families, and create more food.

Therefore, the first thing is to urge Sun Shuao and Gong to smooth the governance of the rivers of the Chu State, so as to solve the problem of grain production in the Chu land for two thousand years in the future, and the governance of the rivers is a major event in the people's livelihood, a thousand-year plan, and it is necessary to mobilize the entire upper echelons of the Chu State to obtain their human and especially financial support, and then improve step by step in some small production links during this period, so as to slowly promote the whole era.

He felt that this was what he could do for this era.

He may not have the skills to create thermal weapons and chemical weapons at every turn, but as a student of the Department of Finance and Economics, years of political training in this life make him unable to identify with some rough era transformations.

The problems of each era are different, and the path of reform is different, and these need to be explored.

Maybe even some great people will inevitably be negligent in this process, and they will create new problems while solving some problems.

This is inevitable.

So you need to be cautious.

Changing an era seems to him to be more like a huge astronomical project, and like the financial figures he calculates, each expansion of the value represents the painstaking efforts of countless people, as well as the various costs of time.

There are many aspects to the reform of a country, such as politics, military, agriculture, economy, culture, system, law, commerce and trade, transportation, environment, technology, and even the ideological transformation of the common people and the ruling upper class......

It's not just a matter of talking.

Otherwise, man-made rockets will go to the sky, and in the future, China's economy will develop rapidly every year, and it will already surpass Britain and catch up with the United States more than ten years ago, instead of introducing various policies every year to ensure growth.

Obviously, reality is different from just thinking about it, and it can be achieved with a pen, which requires the participation of all levels of society and the accumulation of years and months.

Of course, these are not one or two sentences that can be explained clearly to Pan Chong and Mi Huang.

As Marx said, only practice is the only criterion for testing truth.

His inferences based on the experience of later generations will be verified when the water has been successfully managed and new farming tools and modern ideas have been popularized, and these have been fruitful, and now they are only imaginations.

At the last flood conference, many officials remained silent about whether the benefits of the flood control he said were really good, and even disagreed with them from the bottom of their hearts, which is quite normal.

Because the dam repair not only costs the people and money, but also because the site selection failure of the water conservancy project in the past has not produced a positive effect, resulting in the family gate valve that has contributed money and people to build water conservancy can not see the actual benefits and results, so there will be many resistances.
