This principle is easy to understand: Potatoes and sweet potatoes hidden in the ground are far more resistant to flash floods, heavy rains, and Pacific storms than delicate products such as rice.

However, this strategy is not difficult to implement, because the staple crops in Tainan used to be potatoes and sweet potatoes, but now they just continue to increase the proportion of planting.

You know, with the current technical conditions of lack of fertilizers and less medicines, the yield of rice per mu is only five or six hundred catties; while the yield of one mu of potato fields can easily reach three times that of rice, and it can be even higher in the future ——To put it bluntly, they are all starch, and the people who travel through will naturally choose potatoes that can feed more people.

……

After confirming the future planting plan, the two returned to Chikan, and then went south along the asphalt road by the sea. After running for about 10 kilometers, they reached the dividing line between Kaohsiung and Chikan: Erren near the creek.

Since the residential area has not expanded to this area, it is very desolate, surrounded by black land exposed after burning.After running two miles east along the Erren River from the sea, a building appeared in the distance.

Here is the core asset of the General Grain Corporation: the fine seed base.

The fine seed base covers a large area and is composed of a biological laboratory, a greenhouse, an experimental field, a boiler room, and a power generation room.

The biological laboratory is the core building of the breeding base.

At first glance, the laboratory surrounded by four two-story brick-concrete buildings is no different from the small buildings of later generations.Large glass windows, iron railings, and white walls.

The equipment inside the laboratory building is also as close as possible to those of later generations.

All kinds of imported biochemical instruments including microscopes are fully equipped here.In addition, there are some "domestic" low-level experimental equipment including constant temperature culture rooms in the building.

……

After showing the purple leather certificate representing the identity of the crossing people/nobility at the guard post at the gate, the tricycle drove into the base compound.

After hearing the news, Yang Lexi came out to welcome her.

Yang Lele is relatively young in the group of Time Travelers, only 25 years old this year.This gentleman majored in bacteriology at university, but he put his major aside after graduation, and went to a trading company to become a "business manager" specializing in Zambia.

Originally, he thought that life would continue like this. Who would have thought that after time travel, he would pick up the major he had thrown away... Yes, "the country and the people" need his major.

Seeing a group of people in white coats coming out of the building, Liang Letian and Mi Shuo immediately put smiles on their faces, pretending to be inspectors, and warmly stepped forward to hold Yang Lele's hand and shook : "I'm happy, I've worked so hard, there's a serow in the car, and our two brothers specially called to cook the casserole for you!"

"Thank you!" Yang Le's round face was also full of smiles: "I have beef here, let's have a good meal tonight."

After speaking, a group of people entered the building.

The first floor is mainly used for various experiments and storage, and Yang Le usually synthesizes some chemicals here.

After entering the foyer, the entourage brought by Liang Letian and the others stayed here: Everyone's purpose today is clear to each other, mainly to go to the second floor to have a look, so only Liang Mi and the others went upstairs.

After going up to the second floor, Liang Mi and his wife changed into isolation suits and rain boots in the hallway, and then walked through the lime water pool for disinfection, and then followed Yang Lele into the No. [-] laboratory.

The seemingly quiet laboratory actually has a lot of people inside: 10 "female workers" in white coats, each with a microscope in front of each of them, and some bottles and cans behind the long table busy.

Leaning over to look behind a female worker, Mi Shuo, who had worked as an agricultural technician in a seed company, whispered in Yang Le's ear, "That's right, the technology is getting more and more proficient."

"Practice makes perfect." Yang Le smiled and nodded.

……

Potato and sweet potato seedlings need to be detoxified.The work of these female workers is one of the detoxification processes.

For sweet potato and improved potato varieties, as the number of planting generations increases, the plants will become smaller, the growth will decline, the tubers will become smaller, and the yield and quality will decrease significantly-this is called species degradation.

Seed degradation seriously affects crop yield, but what is the cause of species degradation?Virus.

Sweet potato and potato plant viruses will continue to spread in crops through infectious sources such as insects, nematodes, and fungi, causing crops to deteriorate from generation to generation.

The most important work of the seed base at this stage is to use the shoot tip detoxification technology commonly used in later generations to obtain non-toxic improved crop varieties.

Anyone who has seen moldy bread or potato chips will know that the mold is not evenly spread on the bread, but forms plaques of different sizes like drops of ink, which is the normal form of bacterial community growth .

The shoot tip detoxification technology also takes advantage of this: the virus is not evenly distributed in plant tissues.

The virus-free technology is to first cut off the top growth point on the infected tuber, and then perform tissue culture on these parts with a relatively low virus concentration to generate seedlings, and then select non-toxic seedlings from them through testing.

These female workers who are busy on the table, what they are doing is the procedure of using a microscope to select non-toxic seedlings.

Generally speaking, the virus-free rate of a wave of seedlings is only a few percent or a few thousandths.This is also the reason why the laboratory needs so many female workers: each of them has to tediously test hundreds or thousands of materials before picking out some non-toxic seedlings.

In terms of their real identities, these female workers are ordinary migrant women who came across the sea, and most of them are illiterate.

However, just like those female workers on the electronic production line in the later generations, the laboratory does not require them to know any science and technology, but only needs them to use the natural patience of women to mechanically pick out the non-toxic seedlings.

……

After passing through the No. [-] laboratory, the three of them came to the long strip-shaped second laboratory.

Laboratory No. [-] opened up all the remaining rooms in the building.The long passage is flanked by large-format glazing, as well as additional wooden windows on the exterior - designed to provide shade from light and storms when required.

The corridor after opening is very sci-fi.

Long strips of LED light tubes extend along the top of people's heads to the distance. The corners are extended cast iron plumbing pipes. Layers of iron frames are piled up on both sides of the aisle. In the room, the light tubes inside are also emitting soft light, illuminating the rows of triangular glass vessels brightly.

This is the nursery for seedlings.

The non-toxic seedlings selected by the female workers will be cut into sections and put into triangular flasks.A kind of MS culture medium will be prepared in advance in the bottle. After the non-toxic seedlings are put in, they will take root in 3-5 days under suitable temperature and light conditions, and grow into small plants in about 20 days... At this time, you can continue to cut into sections Continue to reproduce, or directly use for breeding the original species.

All the above processes must be carried out in a sterile state, which is why everyone wears isolation suits.

Of course, in addition to this detoxification method, the laboratory will also use heat treatment and some chemicals to deal with different varieties of viruses.

As for the daily work of the director of the base, Yang Lexi, in addition to managing the base personnel and these seedlings, he is also responsible for synthesizing chemical agents and culture fluid for seedlings in the downstairs laboratory.

This work takes up most of his time: the chemical composition in the culture medium is relatively complicated, and the chemical plant is limited by the scale, so it can only provide raw materials in bulk at the moment, and Yang Leyi still needs to do it himself in the laboratory for the specific fine operation of.

In the aisle mixed with sunlight and electric lights, Liang Lexie carefully looked at the petri dishes in the glass box for a while, then turned to ask Director Yang a key question: "We will reclaim 30 to 40 mu of new fields next year." , the main crops are potatoes and sweet potatoes, can you supply seedlings here?"

"No, I'm too busy." Yang Yue shook his head and said, "It's good to say that we can screen and raise seedlings in batches, just add some female workers. Anyway, it's all done according to the rules. But I can't be busy with the synthesis of culture fluid alone. Need help."

When Yang Lele said this, he emphasized his tone: "That kind of real assistant."

"I understand, I understand..." Liang Cifu rubbed the center of his eyebrows with his fingers, which was his habitual action when he encountered troublesome things.

The so-called assistants refer to those top students in Chikan Middle School.Biology and chemistry are advanced subjects. At this stage, only a few top students in middle school have been exposed to junior high school physics and chemistry.And what Yang Lele needs is this kind of student who can be trained as a researcher all year round.

However, things are not that simple.Before this, the big office specifically issued a text for each department: top students must complete all high school courses before considering part-time work and part-study.

So Lao Liang has a headache now: laboratory assistants must have knowledge of physics and chemistry, but these people are now locked up.

After habitually looking at each other with Mi Shuo, it was Mi Shuo who said a hard word: "This matter must be resolved, there will be more fields to be cultivated in the future, and Director Yang will not be too busy to die alone." Come, you will go to Lao Xia tomorrow."

"Well!" Liang Letian also realized the seriousness of the problem now: "Anyway, the situation is like this. This is not because we forced the palace. I will bring it up at the meeting tomorrow and see what they say. If there is a species, don't ask for food!"

Chapter 322

noon.

When a big callused hand grabbed the rope and shook it up and down, the copper bell of "jingle jingle" resounded throughout the campus.

After the bell rang for half a minute, the lame porter came down from the square platform in the middle of the playground and walked towards the gate alone.

And in the teaching building behind him, it didn't take long for a large wave of students to pour out.These students are male and female, they are uniformly wearing blue cloth school uniforms, canvas sneakers, and they are half the age of children.As soon as the students came out of the building, they shouted and rushed towards the cafeteria.

Chikan Middle School was not built for a long time, and the construction started after the completion of the Fourth Primary School.

With the continuous arrival of immigrants, the early Chikan Primary School has been renamed Chikan Primary School, and several subsequent primary schools have also sprung up in corresponding residential areas.

Now, unlike in the past, a certain regime has a population of more than 40.With such a large base, there will always be a small number of people who will be selected.Although the knowledge structure of these people is a bit incomplete, they can already study junior high school courses.

By this time, the establishment of the first secondary school was inevitably on the agenda.

So after the completion of Chikan Middle School, it immediately recruited more than 200 students.

The source is divided into two parts.The first part is the top students who have graduated from various elementary schools step by step.

Although it has been less than 2 years since the time traveler came here, since there are only two classes in elementary school, mathematics and Chinese, there will always be some children in each class who can stand the loneliness and boredom, from morning to night, plus evening self-study Keep working hard - the primary attribute of a Xueba is to be able to endure hardships.

After more than a year of graduation, these children entered the junior high school of Chikan Middle School.

Another part of the students are older people.

Most of these Ming people were petty bourgeois from places like Hangzhou and Fuzhou.As for their identities... down-and-out children, unemployed buddies, beggar monks, and a few scholars, their occupations are very complicated.

The literacy rate in the Ming Dynasty was very uneven, and there were not many readers in a county in a remote area.But in a big city like Hangzhou, even among the small bourgeoisie, the literacy rate is quite high.Those ordinary weaving households usually let their children learn accounting and literacy... In the future, they will be a clerk for someone. If they are lucky enough to survive until they are 40 or [-] years old, they may become shopkeepers.

As the world has become more and more difficult these years, there will always be local "urban people" who can't get along and go to the officials to beg for a living.

Yes, recently, among the immigrants transported from the direction of Hangzhou, the proportion of the number of people from the petty bourgeoisie has shown a slowly rising trend.

The arrival of these people has added a lot of vitality to the Dawei society.Not to mention those who can read, even ordinary weavers are ready-made workers who can endure the boring assembly line work, which is much more useful than those sloppy farmers.

……

After the first wave of children rushed out of the teaching building, after a while, a group of older junior high school students who walked steadily followed out of the building.

These are the boy boys I just mentioned... They also graduated from primary school in a serious way, and they are the best among their peers, but their primary school career is very short.

It is very easy for a guy who can read and do accounts to memorize the simplified characters by referring to the traditional and simplified tables.Like primary school mathematics, once these people understand how to convert Suzhou codes into Arabic numerals, the learning speed is also very fast... After all, it is primary school mathematics, and there is no difficulty.

Therefore, such a scene often appears in primary school classrooms: the little Doudings sitting in the front row study step by step, while those bearded "classmates" in the back row skip grades in a few months, or go to middle school.

And the group of people who came out of the teaching building today are "junior high school students" selected from the vast number of literate immigrants.These people can quickly adapt to the education model of later generations and integrate what they have learned into the framework of new knowledge in a short period of time. They can be regarded as "talents needed by society".

……

The young junior high school students couldn't bear the hunger, and rushed out as soon as the get out of class bell rang.

And these older people are somewhat reserved, so the first small tacit understanding since the establishment of Chikan Middle School was born in this way: let the children go first.

Among a group of talking and laughing old junior high school students, Zhong Simao was considered older.He was already at the age of three, and he used to work as a tent for others in a town near Jiaxing, and by the way ran errands to collect rent for others.

Who would have thought that the tide in August this year would go crazy, and the dikes and dams of Qiantang that had been in disrepair for a long time were broken.Accompanied by the heavy rain at the same time, countless people and animals were drowned in Haiyan, Jiaxing, Shanyin, Kuaiji, Xiaoshan, Shangyu, and Yuyao, and countless people were drowned in coastal and suburban residents. The number of drowned people is tens of thousands."

... It is not an exaggeration to say that Chongzhen is the most unlucky emperor in history: since he ascended the throne in 1628, the seven weapons of drought, flood, locust, tide, hail, gale, and frost during the Little Ice Age are like hearing the starting gun. It also began to wreak havoc in China's richest Jiangnan region in turn, smashing the money bags of the Ming Empire to pieces.

The most coincidental thing is: in the last years of Chongzhen, these disasters gradually subsided... and when Xuan Ye came to power, the Little Ice Age just ended... The fate of the sky, the weather is good, and the evaluation of Guotai Min'an just fell to "eat dead chicken" On Kang Mazi's head, the big hat of Qiangu Yidi was also lifted out.

It can only be said that Chongzhen was too weak.

……

Zhong Simao died in this tidal disaster.

Several villages and mulberry fields where he collected rent all year round were all hit by disasters, the crops were flooded, and the whole family of the farmers was floating in the sea.Not only did his boss's loans go to waste, but all the mulberry orchards and cotton fields he invested in were also wiped out-where the tide washed the land, the land would be salinized and the price would plummet.In the words of later generations, it is these mulberry fields and cotton fields that have fallen to their limit.

So when Zhong Simao saw the owner of the firm hang himself, he also went bankrupt... The little money he saved, including borrowed funds, was also invested in the account of the firm.

Next, the accountant who wanted the account was called to collect the debt...

After losing all his family property, the bankrupt Zhong Simao had no choice but to run away with his wife and baby.Fortunately, it is more convenient to travel nowadays—it is no secret that Tangzhuang outside Hangzhou is "recruiting workers" all year round.

From the moment someone went to Fuzhou to receive the seal of the guerrilla general, the "secret underground population transmission line at Hangzhou Station", which had gradually become untenable, simply hung up the signboard of "Cao's Grain and Taiwan Agency" and started launched a semi-public "labor intermediary" activity.

Outside Tangzhuang Gate, Caishikou in Hangzhou City, and even outside Suzhou City, Hangzhou Station has set up "labor service stalls", ready to transport away the "recruited" bitter hahas at any time.

So Zhong Simao, who had nowhere to go with his family, registered at Tangzhuang and boarded the ship.As a result, after arriving in Dayuan, the family found that they did not encounter the hardships they imagined, and their lives were much easier.

Zhong Simao and his 8-year-old son first entered elementary school together.Then it was useless, Zhong Simao skipped a grade to middle school.

At this time, the Zhong family suddenly discovered that they had money again!

Not to mention that little brother Zhong was free of food, drink, and tuition in elementary school. From the day Zhong Simao entered middle school, not only was board, lodging, school uniform, textbooks, and stationery free, but he also received a monthly scholarship of 2 taels of silver...

"Isn't this the catering staff in the county school?" Poor Zhong Simao, who was born as a clerk, turned out to be the catering staff he had envied since he was a child after he went bankrupt...

The woman from the Zhong family also had work to do: she knew how to do accounts, and soon became a warehouse manager in the street office, responsible for keeping accounts and distributing pots and pans to new immigrants. Her monthly salary was 3 taels of silver.

The vitality of the Zhong family recovered in this way: they calculated carefully, and according to the current income situation, it would probably take less than three or four years to pay off the mortgage.

Therefore, Zhong Simao's gratitude to Cao's warlord regime is increasing day by day.Yes, in the eyes of Ming people, the Cao family is just like the Zheng family in history, just a traditional warlord, no different from Wu Sangui, Mao Wenlong and others.

……

When a group of short-haired "cookies" came to the school cafeteria talking and laughing, the young junior high school students were already eating with iron lunch boxes.

Today's lunch is ordinary: a large piece of deep-fried yellow lip fish in tomato sauce is the main course, with fried seasonal vegetables as a side dish, and each person can get a small bowl of yogurt.The staple food is mashed potatoes, unlimited roasted seaweed and seaweed egg drop soup.

Chung Simao was genuinely satisfied as he ate the sweet and sour fried fish cubes topped with red tomato sauce.

It's not that there are no high-quality meals and famous dishes in the Ming Dynasty, but they can only be eaten when rich families or businessmen hold banquets.Zhong Simao had never seen such a delicious meal in a county school here.

There was a sound of chewing in the cafeteria, and it was enjoyable.When everyone was halfway through eating, the teachers came in one after another.

When four or five teachers came in one after another, the students were still munching... There is no need to salute in the cafeteria.

And when the teachers passed behind Zhong Simao, he suddenly felt a light pat on the shoulder, and then a small voice sounded in his ear: "Go to the principal's office after eating, someone wants to see you." you."

Zhong Simao turned his head in astonishment, only to find that it was Mr. Jiang Shang who was speaking, the youngest but extremely knowledgeable teacher in Chikan Middle School.

After saying this, Jiang Shang, who had already put on a pair of imported myopia glasses, patted Zhong Simao on the shoulder, smiled, and turned away.

Zhong Simao is not calm now.Although he has never communicated with the principal, he knows that the principal is a high-ranking official here, just like the Guozijian Jijiu and Ritual Minister of the Ming Dynasty, he is a great man.
