Chapter 341 Sweet Potatoes

To reciprocate, Shi Yanren really wanted to do something to show his gratitude.No, not only for the chemical industry department, but also for the Industrial and Energy Commission, the Agricultural Commission, the Army and Navy, and the Civil Affairs Commission...

Counting with fingers, it seems that there are too many departments and people who want to express their gratitude, and it is inconvenient to favor one over another.To say that the best way seems to be to send a friendship to all the time-travelers in these places.

This is more difficult.The Ministry of Health's job is to save lives and heal the wounded. Generally speaking, the people in the Ministry of Health enjoy unparalleled expert treatment in the time-traveling group, and everyone is very polite wherever they go. In this time and space, medical treatment is the scarcest resource. No one dares to say that he will be healthy forever, not sick, not injured until he becomes one of the five hundred powerful family leaders.

This is a mixture of fear and respect, and Shi Youren doesn't take seriously the respect caused by "I'm afraid I will ask him for it in the future, and it will fall into his hands".

The Ministry of Health is too respectful now. From the perspective of long-term stability, it should do something to win more favor from everyone.

Shi Yanren's eyes fell on the road outside the window. The early summer sun was shining brightly, and the street trees that had just been planted beside the road were all wilting.People who walked by, whether they were time-travelers or indigenous workers, were all wearing straw hats and sweating profusely.

"Well, heatstroke prevention and cooling down." Shi Yanren immediately thought of this.Liu San said that he wanted to mix several traditional Chinese medicines, making Zhuge Xingjun powder, ten drops of water, and Huoxiang Zhengqi water.The sources of medicinal materials for these three things are easy. They can be purchased from local pharmacies or grown by yourself, and the excipients are just ethanol.It is very effective for summer common diseases.

However, it takes time to make medicine. It is difficult for Liu Sanjia and his apprentices to dispense enough medicine. The workers in the pharmaceutical factory are no better than ordinary workers. things.

"Well, salt water!" Shi Yanren suddenly thought, "Salt soda!"

Salt soda is a labor insurance product. It is the best drink for manual workers in summer. It not only prevents heatstroke and cools down, but also helps maintain electrolyte balance in the body and avoid dehydration.

But Shi Yanren immediately realized that he didn't have baking soda, not only he didn't have it, but the Ministry of Chemical Industry didn't have it either.Baking soda is not a rare thing, but there must be soda ash first.If the soda ash plant is not in operation for a day, there will be no baking soda available for a day.So after thinking about this idea, I had to give up first.

If you can't make soda, you might as well make normal saline first.When Shi Yanren thought of this, he decided to take a trip to the pharmaceutical factory.Waiting for He Ping to prepare to explain some administrative affairs and Mongolian doctor training class - this is the nickname they privately gave to the first doctor training class. Recruited through the Internet, the Ministry of Health recruited four or five to try to escape by studying medicine. Work and satisfy special hobbies through the public.

He Ping waited and waited but didn't come. When he was anxiously waiting for him, a man with glasses walking cross-legged, with the number "007" impressively on his chest.When Shi Yanren took a closer look, it was Dugu, the director of the Dongmen City Police Station who proposed marriage.

"Doctor, please show me the disease...here." Director Dugu quietly pointed to a certain part with his hand.

Shi Yanren inquired carefully, then lifted his clothes to look at his physical signs, and he knew it.

"Chlamydia infection, it's not a big deal." Shi Yanren said more reservedly.

"What is chlamydia, inflammation?"

"This..." Shi Yanren thought for a while, "No big problem, infection, infection." He wrote a prescription, "Take the prescription and go to the pharmacy to get the medicine from Hippo, and ask Sister Li to give you an injection. It will take two or three days to recover." Shi Yanren comforted him, and casually took out a small cardboard box from the table and gave it to him, "Be careful when you go in and out."

Dugu was shocked when he proposed marriage: "Yes!"

"It's okay, it's not a serious problem." Shi Youren said with a smile, "It's better to have less contact with indigenous women in the future."

"Understood! This is no problem!"

"It's really no problem. Pay more attention to your body and get injections on time." Shi Yanren comforted him for a long time, and then gave him some advice before sending him out.

"If it wasn't for erythromycin, you would have been in serious trouble!" Shi Yanren muttered behind his back.He knew that a lot of people had hooked up with indigenous women recently.Originally, the executive committee thought that Ming Dynasty was a feudal and ethical society, and the social atmosphere was very closed. As long as everyone was restrained from prostitution and rape, there would be no problems between men and women.Now it seems that the so-called feudal ethics is the same thing.

Now Shi Yanren didn't have the heart to wait for He Ping, left a note on his desk, explained a few things to be done, and went to the farm.

Wu Nanhai is not in the office. According to Chu Qing, his office secretary, "Master is in the grain processing factory, processing sweet potatoes."

"By the river?" Shi Yanren had never been to this place, only heard that there was a mill there, which processed rice for the locals.

"Just go out from here and go to the south..." Chuqing's Mandarin is a typical "Guangpu" of this time and space, and she is deeply influenced by Wu Nanhai when she hears it - Shi Yuren knows that not only her, but also the people here The long-term foreman Wang Tian also has such an accent.

Since Wu Nanhai's Agricultural Committee moved to Bairen City and opened up a farm, sweet potatoes were the first crops to be planted.

As a high-yield and stable crop, sweet potato has the characteristics of wide adaptability, strong stress resistance, drought tolerance, and less pests and diseases.In addition to serving as rations, fodder, and making starch, even the leaves can be used as high-quality green fodder—almost no waste.Planted in places with good water and fertilizer conditions, the general yield can reach 3000-5000 kg per mu, and some can produce 7500 kg per mu.Compared with hybrid rice that can only be planted once and will fail, it is a more meaningful "traveling artifact".

But in this time and space, sweet potatoes are not very qualified as "artifacts".Sweet potatoes are nothing new here.It was introduced from the Philippines to China in the Wanli period.First of all, it is planted in Guangdong, and Qiongzhou, which is across the sea, is also planted near the water.Travelers often see sweet potatoes when they go to the countryside.

Before sowing the sweet potatoes, Wu Nanhai once asked Wang Tian for the sake of caution—he is also a farmer, how is the sweet potato planting in Lingao?Wang Tian said: This thing has been planted in Lingao for seven or eight years. It was originally a seed potato brought from Qiongshan Mountain. There are not a few people who plant it.Harvested potatoes are useful for people to eat and to feed pigs.The growing season is short, and Lingao can harvest twice a year.It is an excellent miscellaneous grain - it is not resistant to storage.The local climate is humid, and sweet potatoes are easy to rot.The growers here don’t know the various ways to store sweet potatoes in cellars. Some people have tried sliced ​​and dried sweet potatoes, but it is easy to mold during the rainy season.

"It's a lot of harvest, and it doesn't need manpower or fertilizer. At the most, you can harvest a thousand catties per mu. But this thing can't stand it. It's useless for small households to plant too much. There are many long-term workers in the family and many livestock. Small and large grain households grow more."

"Wu Dong's family! There are so many long-term workers and short-term workers in Bairen and Bopu's farms, but we can grow some sweet potatoes. It's a bit of a loss to feed rice to the long-term workers. In fact, rice and potato shreds are half and half. , give half a bowl more than the amount above, and some pickled vegetables and salted fish, it is already a meal for busy farming. It saves food." Wang Tian enthusiastically made a suggestion.Then he used the tricks he learned to save money for the landlord when he was the "leader" of the landlord one by one to present treasures to Wu Nanhai.

A complicated expression flashed across Wu Nanhai's face. From a good point of view, this shows that Wang Tian has the meaning of "loyalty to the Lord". From a bad point of view, Wang Tian's behavior is no different from that of a "traitor".Wu Nanhai used to hear people say that when foreigners came to China, they were honest and honest, but they were brought down by a group of fawning "traitors".Although biased, it is not unreasonable.

"This, discuss it again, discuss it later." Wu Nanhai couldn't stop his heart.

Seeing that Wu Nanhai's face was uncertain, Wang Tian didn't know where he said something wrong, so he kept silent.

Wu Nanhai thought for a while and asked, "You said that one mu can only collect a thousand catties?" He didn't believe it.When he went to the countryside to practice this thing, he knew that farmers could harvest two to three thousand catties per acre by planting whatever they wanted.

Wang Tian said: "It was more than 2000 catties in the first year, and then it decreased every year. It was only eight or nine hundred catties."

"impossible……"

Fa Shilu nodded and reminded him: "Virus infection."

"Yes, yes, I actually forgot." Wu Nanhai looked ashamed.This is very basic knowledge, he actually forgot all about it.

Sweet potatoes, including potato crops, have been propagated asexually for a long time and will be infected with various viruses during growth and storage.The virus will continue to accumulate in potato pieces or potato seedlings, causing serious degradation of seed quality, deterioration of quality, and a substantial drop in yield.The production reduction range is more than 30% to 70%.

During the autumn harvest season in 1957, Hongdong County, Shanxi Province set the country's first "high-yield record" of sweet potatoes at that time: the yield of sweet potatoes per mu of Fenming Agricultural Cooperative in Mamu Township was 5510 catties.

The yield of sweet potatoes per mu is 21 catties, which is not uncommon in the 1957st century—new varieties of high-yield virus-free sweet potatoes, if planted carefully, the yield in the first year will not be less than [-] catties.But in [-], it was already the number one in the country-this number one in the country is still somewhat watery.If sweet potatoes do not have professional technical support, the yield is not too high.

So far, there are no highly virus-resistant sweet potato varieties in agriculture, and there is no specific agent for preventing and controlling viruses.Only the use of detoxification technology can prevent and control viral diseases and improve the yield and quality of sweet potatoes.

Modern farmers don’t need to save and produce their own seeds, they are all arranged by professional seed companies. Wu Nanhai went to the countryside for an internship. What he saw, planted, and talked about were all poison-free sweet potato seedlings. He only needed to consider what The soil and climate can be matched with any kind of potato seedlings. Naturally, there is such a layer.

Even sweet potatoes that have been specially detoxified will be reinfected and degenerate after three or four years of planting.How to detoxify is a specialized high technology.Fa Shilu has considered various solutions on how to solve this problem in this time and space.He also brought a set of laboratory equipment specially used for detoxification.

The first batch of high-yield virus-free sweet potatoes of the travelers were planted in December 1628.Generally, in areas with distinct seasons, sweet potato seedlings start in February, transplanted in April, and harvested in August.The temperature of Lingaosheng is above 2 degrees all year round, so it can be planted all year round.In order to ensure that the seedlings are not leaked, the key members of the Agriculture Committee, such as Fa Shilu and Wu Nanhai, planted the seeds themselves, and none of the indigenous workers were used.Under careful maintenance and management, the harvest was ushered in at the end of April this year.Ten acres of sweet potatoes planted experimentally achieved a good result of 4 kilograms per mu—because of the lack of chemical fertilizers, this harvest is far from giving full play to the advantages of the variety.In order to harvest sweet potatoes, soldiers from the army, navy and students had to be mobilized to help.

The farm had a bumper harvest of sweet potatoes, with more than 8000 catties harvested per mu. This yield shocked not only Wang Tian, ​​but also all the workers on the farm.The news spread quickly, and many people wanted to see what the Australian sweet potatoes looked like. Wu Nanhai asked the army soldiers who helped harvest the potatoes to guard the periphery, and no outsiders were allowed to enter the farm field until the sweet potatoes were completely harvested.

Eighty thousand catties of sweet potatoes is not too much even by ancient standards.In rural areas, it is often stored in a cellar, and then used slowly.However, after April and May in Lingao, the weather will soon enter the rainy season, and there is a certain risk of mildew and rot in the cellar.Moreover, there is an urgent demand for starch, the main product of sweet potatoes, in various industries of the crossing group.In the end, Wu Nanhai decided to save some seeds for promotion, and transport the rest to the grain processing factory to be processed into finished products.

There are many products that sweet potatoes can produce: vermicelli, vermicelli, maltose, glucose, dextrin, rice wine, alcohol, soy sauce... In fact, everything is inseparable from it, mainly starch derivatives.Therefore, Wu Nanhai determined that the processing of sweet potatoes is mainly to produce starch, and the waste residue and waste generated during starch production are used to take into account the production of some by-products.

The Ministry of Light Industry is also very interested in the harvest of a large number of sweet potatoes. Mo Xiaoan must come to report once a day, and constantly put forward his own opinions on what new things to produce.Unexpectedly, his most eager product is not the seemingly "very modern" glucose, dextrin, instant rice noodles and the like, but dried sweet potatoes—to be exact, Liancheng red heart dried potatoes—the famous Fujian One of the eight dry state.

"This stuff sells very well." When Shi Yanren ran to the bamboo shed known as a food factory, he saw Mo Xiao'an explaining: "Back then, it was an export material, and even now, sweet potato fries are also a very popular snack. , the sweet potato is still a rare thing in this time and space, and it can be used as a high-end route..."

"I think this..." Wu Nanhai is not optimistic about the dried sweet potato plan, "The natives in this time and space seldom eat snacks, that is, some people who have money and time to eat."

"Lingao has no local market, so it can be exported to Guangzhou."
