In Jiangnan during the Song Dynasty, human manure was mostly applied directly to the fields. However, in the Yuan Dynasty, farmers had generally used the method of rotting, "placing brick sills on the head of the field, and then using them after the cellar was ripe".

However, the natural ripening method is too time-consuming, usually more than half a year.

Jiangnan in the Ming Dynasty began to use the "steamed manure method". In winter, when the ground is warm, dig a deep pool to collect dung, close it and cook it, cover it with soil, and close the door to make it hot and rotten in the house. The resulting cooked manure is also known as "steamed manure".

In addition, some "boiling manure method", "simmering manure method" and "cellar manure method" in the Ming and Qing dynasties are all secondary processing technologies spontaneously researched by the folk in order to accelerate the corruption of fertilizer. However, in the final analysis, these are scattered and unskilled manual work, and quality and yield cannot be guaranteed.

Now that the beggars have unified the manure industry in Hangzhou and integrated the raw material transportation channels, then the Weituo manure field outside the city can give full play to the power of industrial production of farm fertilizer.

Large quantities of manure and municipal garbage are first piled up in the manure field.

All kinds of human and animal manure and straw and other green manure will be piled up in proportion, and the most important thing is to adjust the carbon to nitrogen ratio: generally 30:1, that is, each nitrogen must have 30 carbon sources.

Human and animal manure contains more nitrogen, and crop straw contains more carbon, so generally speaking, about 40% of straw should be added to each ton of manure.

After the various straws have passed through the crushing and soaking process, they can be layered with the manure. In order to preserve nutrients, some finely ground garbage is sprinkled into each layer. The material is piled up and sprinkled with water until a 2.5-meter cone is formed, and the material is finished.

Next is the crucial "dumping" link.

After the compost pile is piled up, the internal temperature can reach 60°C-70°C within 5 to 10 days.

This is where the artifact comes in: the thermometer lever.

Under the protection and monitoring of several specially trained literate homeless people, the daily task is to take the thermometer rod and plug it into the cone.

Once the temperature in the manure pile is qualified and maintained for 10 hours, immediately overturn the manure pile, break up the large pieces, mix the manure and grass, replenish the water, and then pile it up as it is.

In about 10 days, the stack temperature rises to about 60°C again, and then it is overturned once, and the stacking is completed.

Under the guidance of the crossing artifact, every 20 days or so, a batch of farmhouse fertilizer with qualified quality and stable fertilizer efficiency will be produced. Rows of neat dung heaps are like forests, and hundreds of well-fed and well-fed homeless people are busy here.

The fertilizer effect of the new variety was soon reflected in the rape fields outside the city, and a large number of vegetable farmers in the suburbs began to spontaneously row small boats to Weituo to buy fertilizer.

In Hangzhou alone, there are thousands of dung diggers and boatmen, and there are no less than 500 public toilet construction teams...... These people are also responsible for cleaning up the garbage heaps that have accumulated in the city little by little, and clearing the mud from the gutters everywhere. In short, everything that can become fertilizer will not be let go.

The vigorous transformation of the urban environment made Liu Mengqian, the prefect of Hangzhou, who was originally evaluated in history only chanting words and paintings, and was satirized by Zhang Dai, became a "capable member" overnight and was praised by gentry from all walks of life.

And the first pupa Zhou Tong Zhou Da gang leader, now can swagger into the county yamen in broad daylight - not only officials, but also all the gentry in Hangzhou who care about this matter, after figuring out how Zhou Tong's fertilizer industry is a virtuous circle, they are all amazed.

Of course, the Zhou gang leader went out and went out, and after a thousand calls, the "soft hedgehog armor" he wore close to his body never took it off. There is no way, there are too many enemies, and Lao Zhou still has to save his life until the day he becomes a member of the CPPCC.

......

Lu Cheng, as the stationmaster of Hangzhou Station, was also busy during this time.

Not only must we always stand behind the beggars to guide the country, but also take into account the overall work of Hangzhou Station, maintain contact with all parties, and in addition, help some people wipe their butts......

A person who posted a small selfie video that caused serious discomfort to the viewer has run away, and the projects that are half of the projects left behind by this goods need to be taken care of by Lu Cheng.

The first is the field.

After Master Huang was promoted, small landlords from all walks of life came to "donate" the land, and there were not too many rich peasants. This is essentially an affiliation: the land is still owned by the family, and everyone partners to use the tax-free quota to make a profit.

However, the traversal people do not need this kind of affiliation, and what the traversal people need is their own land that is completely under their own control, and there are no tenants, and they can install displaced people to work as temporary workers.

This kind of land is difficult to buy in the Jiangnan area: there are too many gentry and wealthy households, and after hundreds of years of changes, the fields have long been scattered into countless private fields, on which are stationed yeoman farmers and tenants, and it is difficult to buy a large number of connected land.

Of course, if Huang Juren gets mixed up to the point that Xu Jie, Xu Ge Lao, he can also enclose the land on a large scale - the king of Xu Di has been from the first assistant to the squire, and his land has experienced annual encroachment, with as many as 240,000 mu and tens of thousands of tenants.

Therefore, it is basically impossible for a small person like Huang Ping to buy a piece of fertile land in the Jiangnan area.

But now there is an opportunity.

Perhaps there is a providence in the underworld, although the Xiaoice River period runs through the end of the Ming Dynasty, but from the first year of Chongzhen, the natural disasters in the Jiangnan region suddenly entered the climax stage: various large-scale disasters represented by drought, waterlogging, and locusts, and finally Chongzhen Dynasty, year after year, although there are many reasons for the fall of the Ming Empire, but endless natural disasters are the thickest coffin nails.

In July of this year, there was a severe drought in the south of the Yangtze River, and then torrential rains, and on the 23rd, a hurricane broke through the dikes on both sides of Qiantang, and all the coastal areas of the three provinces of Hangjiahu were affected.

The floods were followed by the plague, which led to the loss of land, and the salinization of the fields due to the flooding of the tides.

...... Well, a large number of fields that have lost their owners, a large number of bankrupt yeoman farmers and tenant farmers, these will come after July. Recently, Lu Cheng frequently traveled to several coastal counties east of Hangzhou, just to investigate and count the data of various fields.

In the original plan, these tasks should be completed by Master Huang, but the plan could not catch up with the changes, and now Lu Cheng can only hurriedly open a "rental stack", under the guise of helping Huang Juren manage and purchase acres of land, and visit and investigate everywhere.

In order to cope with the tidal disaster that will come in a few months, Lu Cheng not only has to step up the transportation of a large number of "existing" displaced people, but also to investigate in advance, plan the disaster fields, and also apply to the senior staff to apply for a full-time agricultural person to come to Hangzhou with the seeds of certain crops - where floods and droughts and floods are frequent, don't think about rice, potatoes and sweet potatoes are the root crops.

......

Even in this kind of busy schedule, Lu Cheng still has to take time to participate in some entertainment, such as the opening ceremony of Huang Ju's money bank.

As a lifter, it is normal to open one or two money shops and teahouses. Before Huang Zhicheng left for Fujian, he had already completed the membership procedures in the Money Industry Association, and bought a money village at the mouth of the rice market.

This bank, which specializes in exchanging silver coins, is nominally the property of Mr. Huang's family, but in fact it is presided over by Lu Cheng, and its main function is to provide industrial metals for adults: gold, copper, lead, tin, etc.

Needless to say, the gold-silver ratio between the Ming Dynasty and Japan was about 1:8, and the European price was more than 1:12 during the same period, so the colonists had been buying gold from the Ming Dynasty and Japan. Now the traversal has joined in - after this village, there will be no such shop, and in a few years, the price of gold will be leveled.

As for the other copper, lead and tin, these are all industrial metals that are in great need, especially copper. The most important task of Huang Ji Qian Zhuang is to exchange silver for all kinds of copper coins: even if it falls on the ground and becomes eight petals of bad money, Huang Ji will also take out the silver of white flowers to exchange, of course, this kind of words, 1 two for 1 run, don't think about it, 3 times can't be.

In essence, this is actually crossing the public to exchange freshwater cultured pearls for high-grade copper, lead and tin metal ore, and no one can tell who makes and who loses.

......

With the arrival of the first shipyard of industrial products in the big part of the year, Tangzhuang, a freight distribution station in the 17th century, finally ended the embarrassing operation of only buying but not selling, and began to get on the right track.

Industrialization has a standard feature: cheapness. No matter what the commodity, from a sewing needle to a large oil lamp, paint, guns, jeans, and a car, as long as the production line is started, then even if it crosses the ocean, these goods can also smash the market across agricultural countries.

At the end of the Qing Dynasty, the steam country, which seemed extremely simple in the eyes of later generations, relied on the whirring steam production line, freight to the seven seas, hegemony of the five continents, the wealth of the country and the strength of the people, the market of countless ancient empires was blown away, and countless colonial treaties were signed, foreign fire, foreign smoke, foreign oil, foreign cloth......

In this era, an epoch-making process began for the plane, with the first ships of industrialized drying and cutting commercial timber transported to Tangzhuang—global trade entered the buyer's market 300 years ahead of history.

Even if it may take a few more decades for the people of the world to feel what it means to buy one get one free, the arrival of this ship of timber, like Watt's steam engine, sounded the clarion call of the industrial revolution and represented the advent of a new trade pattern.

......

Nowadays, the variety of goods transported to Tangzhuang by the sand fleet has gradually begun to be enriched, and the exquisite industrial products have soon opened up sales channels in Hangzhou.

"Master Gou, Uncle Gou, you are an old patron on the counter, can you still believe in my Zhao Da's craftsmanship? This eighteen clay works inside and outside the city of Hangzhou, I Zhao Da said second, which one dares to call the first? ”

On the river beach in the north of Tangzhuang, in the middle of rows of light red, knife-like red brick stacks, a group of masons are surrounding the butler-like people to pull business, Zhao Dahei, who just spoke, is thin and small, full of calluses, and his whole body is full of craftsman temperament.

"The Queen Mother has also given you the day! Look at what you can! Before Steward Gou could reply, there was already a craftsman Guo on the side who began to speak up. The tall and ugly craftsman Guo scolded angrily, and instantly turned back to the face of the Akita dog: "Master Gou, this art of smearing foreign ashes, I really learned it in Tangzhuang, I don't believe you, please look ......at it."

As Guo spoke, he showed a gilt mounting flower, written with a brush, and covered with two or three red clay seals of the "first-class cement construction certificate".
