Chapter 730 Changzhou and Raozhou

Yan Jidao said: "Those who know me say that I am worried, and those who do not know me say what I want." I have resigned from my official position, sold the property in Beijing, and escorted Brother Zheng all the way south. Su Mingrun is the best at demagoguery, and this time he asked His Majesty to put you in charge of Changguo, and under his arrogance, he definitely didn't have a good heart. ”

Zheng Xia continued to shake his head: "I still agree with Shaobao's words, if you make a mistake, you have to take responsibility, and I can't blame others for what happened." ”

"Brother Xian, life on the island is not easy, your kind and foolish brother understands it, and the whole family suffers with me, Zheng Xia will not dare to agree."

Yan Jidao sneered: "The heat and coldness in Beijing, I can see enough, it is better to have a good time with Brother Zheng's poetry and wine career, this time I will go to Hangzhou to see how I expose Su Mingrun's hypocrisy!" ”

……

In June, the weather is very hot, and on the edge of the lake in Changzhou, countless lifu are building embankments.

Lu Jiawen was wearing a short kudzu shirt, sweaty, and a straw hat, under the collar under his neck, and the place on his neck that could get the sun was completely two colors.

The Zhuhu construction site is only one of the major engineering sites in Changzhou, and now the entire Changzhou, along the Taihu Lake between Wuxi and Yixing, are building various projects.

This project is called the port of the city.

The technology used in the harbor is called bamboo and wood fence permeability technology.

To put it simply, on the swamps and tidal flats along the lake, plan out the waterways and fields, and then nail down wooden stakes and bamboo stakes, and divide them with bamboo and wood fences.

After digging a deep water road, the mud in the river channel is taken out and transported to the soil planning area for accumulation, and the water in the soil will be leaked out of the fence, gradually turning the swamp into a state where water is water and soil is soil.

The waterway that runs perpendicular to the shore of Taihu Lake is called "Ligang", and the cutting waterway perpendicular to Lihu Lake is called "Hengtang".

The port and Hengtang cut the tidal flat swamp into square polders, and the area of a field is often three or four square kilometers, which can accommodate one or two villages.

The area around the polders and waterways is a high dam area formed by digging the river and extracting soil, and it is possible to grow vegetables, mulberry trees, and build houses.

The lowlands inside are large paddy fields where aquatic crops such as rice, lilies, and lotus roots are grown.

In the middle, there is a pond where ducks, geese, fish and shrimp are raised.

This is a perfect ecological cycle system in the shape of a hollow square, with fertile lake mud taken from Taihu Lake every year, which, together with the village's farm fertilizer, provides the crops with the required fertility.

Mulberry leaves raise silkworms, and chickens and ducks are placed under the trees; silkworm manure and chicken and duck manure, which are also used for composting and fish farming; Fish manure in turn forms fertile pond mud, which is used every year to meet the fertility of the highlands.

In order to ensure harvest during drought and flood, it is necessary to set up sluice gates at every port, that is, at the junction of the waterway and Taihu Lake.

At the same time, a reservoir should be built in the upper reaches of Taihu Lake to attract trunk canals to provide water for the port area.

When the flood arrives, the upstream gates are lowered to divert the main flow into the lake.

At the interface between Ligang and Taihu Lake, the sluice gates are also lowered to prevent the rising water of Taihu Lake from backing up into Ligang and Hengtang and flooding the polders.

In the dry season, the upstream gate is opened, the port gate is lowered, and the water from the main canal is enclosed in the port, which can also ensure production.

Most of the time, Taihu Lake is the source of water, and fish and shrimp can also be caught in the Hengtang of Ligang.

The village is generally located on the high waterfront of the harbor, and the life is convenient and comfortable.

This is simply a legend created by an agrarian civilization.

This year's drought situation, because of the 1 million special funds arranged by Su You, as well as the construction project presided over by Jia Kang and Shen Kuo in the early stage, barely allowed the existing fields around Taihu Lake not to suffer from the harsh drought.

According to Cai Jing's statistics, the rice output of one Taihu Lake basin is enough to support the drought of the entire Liangzhejiang Road!

Lu Jia asked why Su You had always scoffed at his set; also finally understood why the prince Wang Xianggong, who was in Jiangning Mansion, wrote to admonish him and asked him to fully cooperate with Su You.

Just look at the attitude of Huzhou Sun Juesun and Suzhou Wang Hui, it is clear that the two old men are afraid that Changzhou will cut off the downstream water source in order to protect their own production, and they will supervise back and forth every day.

Looking at the heavy ears of rice in the polders, and then looking at the farmers' respect for Jia Kang and Cai Jing, Lu Jiawen couldn't be untouched at all.

The imperial court has issued an edict and praised Wang Anshi, Zhao Luan, Su You, Shen Kuo, Jia Kang, and Cai Jing for their efforts in controlling the drought.

Thinking of the words that Su You once promised, to make progress with merit, even if I see that you are not pleasing to the eye, I have to pinch my nose to ask for merit for you, Lu Jiawen's heart became hot again.

The subordinates came over: "Taishou, the medicinal materials in the capital are here." ”

Lu Jia asked: "Then hurry up and distribute it, by the way, each engineering team, with 100 people as a team, buy a large vat, and the cool medicine drink must be guaranteed every day." ”

Tong Juan nodded and turned around and was about to leave, when Lu Jia asked and stopped: "Su Shaobao said, everyone is waiting, you must not use raw water, no matter how hot the weather is, you must also use mosquito nets, these two must be strictly supervised!" This is a good method used by the Guangrui army, and immigrants from northern Shaanxi to Jinghu can not lose a single person, and there is definitely a doorway here. If you understand, you have to do it, and if you don't understand, you have to do it first, do you understand? ”

Tong Juan nodded: "Understood." ”

Lu Jia asked, "Go ahead, I'll go and inspect the granaries and supply silos again." ”

……

Raozhou, Yinshan Supervisor.

Zeng Bu looked at the thin iron sheet in the thick-glazed white porcelain channel steel, and looked at the solution that had turned from blue to yellow, and felt that he had just opened his eyes.

This sense of excitement is no less than just making a proud new poem, reading a good article, the kind of comfort that pours down from the head and reaches the tip of the tail vertebrae, how many years has it not been?

The liquid in the tank has undergone many magical changes.

Shi Lian said: "Yinshan Mine is an associated mine, mainly copper, and there is a lot of gold and silver. ”

"After the ore is crushed and soaked in acid, this blue liquid can be obtained."

"The liquid is mainly copper and silver, and the rest of the mud is solid gold."

"Washed through the sedimentation tank, the gold was left because the specific gravity of the sludge was different."

"The rest of the liquid, when added to the zinc flakes, can release hydrogen and reduce the black powdered silver."

"Filter out the silver, add the remaining solution to the iron sheet, and the copper can be reduced to the iron sheet."

Zeng Bu was amazed: "The same is true over there on the lead mountain? ”

Shi Lian said with a smile: "It's even simpler on the side of the lead mountain, there is a bitter spring there, which can directly concentrate the bile alum solution, and add iron sheets to reduce the copper, which is better than the previous mining and smelting methods, saving labor is nothing less than the world." This is wet alchemy! ”

Zeng Bu shook his head: "Lead Mountain, Yinshan, Raoping, Yongfeng, if they all recommend this method, the copper production of my Great Song Dynasty this year can at least double!" ”

Shi Lian nodded: "What Shaobao means, at most next year, the two Zhejiang branches of the Huangsong Bank can change from the salt standard to the copper standard, and liberate the production performance of salt......"

Zeng Bu was born as a third envoy, and he was naturally clear about these routines: "Next, we should use copper as the foundation and issue treasure banknotes and copper coins to stimulate business travel and expand the scale of trade." Liangzhejiang Road, in the blink of an eye, earth-shaking changes will occur. ”

Shi Lu smiled: "Taishou, don't worry about the class anymore?" ”

Zeng Buhaha laughed: "Today, Fang believes that Su Shaobao has the ability to turn stones into gold, and he also believes in his glorious wind and moon." I'm going to Jingde to sit in town, and I have to take out something when the time comes, I can't watch that little kid in Huzhou get his will! ”
