Chapter 1191 Great Victory

Previous page        Return to Catalog        Next page

    After detecting all silkworm moths, Jiangnan Group¡¯s large forces began to withdraw from the three counties of Huzhou.

    On the day the large forces withdrew, the streets in the three counties were deserted, and the people all ran to the river to see each other off.  There were no flowers, banners, or touching scenes of parting with tears.  They just silently stuffed jars of home-brewed local wine, baskets of peaches and watermelons, loads of dried vegetables and salted fish into the boat where the team members were riding, and then ran away shyly, not caring about what they were doing.  It won't sink the ship

    The people of this era are not yet so aware, and are even a little numb.  But as long as you are a human being, as long as you do not believe in a god, you will definitely have a heart of gratitude and know who is good to you.

    Although the final result has not yet come out, the people agree!

    They kept sending Jiangnan Group¡¯s fleet to Taihu Lake before reluctantly turning back.

    "This is such a touching scene. The employees of the group are connected with the people of Jiangnan" Wang Shimei, the propaganda director of Jiangnan Group and Wang Shizhen's cousin, was so moved that she wiped away tears and looked at several propaganda officers who were painting quickly.  Said: "Hurry up and record all these scenes. I will put them on the front page of the next issue of "Jiangnan Newsletter"!"

    ? ? ? ? ? ? ? ? Alas, this warm and touching scene suddenly changed

    ??~~

    ¡°However, not all the work teams have been withdrawn. After all, whether the fight against the epidemic will be successful or not will not be known until the summer silkworms hatch.

    Zhao Hao left a working group of 30 people in each of the six counties, composed of agricultural technicians, medical students, and Jiangnan textile representatives, to continue to track and detect the hatching and growth of summer silkworms.

    Sericulture farmers in various counties have also begun to get busy. They want to 'green' the silkworm eggs so that they can hatch summer silkworms.

    The so-called "Dian Qing" is the great wisdom of the working people of our country.  Because silkworm moths have evolved a characteristic in nature that allows silkworm eggs to go dormant first, and then begin to develop after the weather gets warmer after overwintering. In biology, this is called "diapause."

    Diapause can help silkworm babies avoid the harsh winter, but it is not friendly to silkworm farmers, because their silkworms can only breed once a year.  Especially in the warm Jiangnan area, after the spring silkworms lay cocoons, there is still a long summer and autumn season in which they can continue to raise silkworms.

    But the eggs laid by silk moths will remain motionless no matter how high the temperature is. They have to be frozen for a while before they can begin to develop silently in the second year.  This greatly limits the production of raw silk around the worldWhy is Japan so short of raw silk?  Isn't it because the silkworms they raise themselves have too low yield?

    Only Chinese silkworm farmers invented the method of ¡®greening¡¯ as early as the Song Dynasty to relieve the diapause of silkworm eggs and allow them to develop in more than ten days after being laid.  Only in this way can we raise summer and autumn silkworms in addition to spring silkworms, and the output will naturally increase dramatically.

    They will intervene from the mating stage. Two hours after the male and female have mated, they will manually separate the male moths and allow the female moths to lay eggs.  Leave it for another half day to allow it to be fully fertilized, then soak the mulberry paper covered with silkworm eggs in warm water for ten seconds, take it out quickly and dry it.

    After about eight days, a cyan spot will appear on the top of the black silkworm eggs, which is called ¡®dianqing¡¯.  The green silkworm eggs will hatch soon.  This is the so-called ¡®promoting youth¡¯.

    According to Ma Yilong's speculation, this method is to use warm water to take away the heat from the surface of silkworm eggs, making them mistakenly think that it is cold.  Then the temperature slowly picked up, and I thought it was spring again.  When the conditions are met, diapause is terminated.

    In order to prove his conjecture, he put the silkworm eggs into an ice cellar for a period of time and then took them out. He found that the greening was successful, and the greening rate was much higher than using warm water alone.

    Zhao Hao also provided him with a new method.  Washing with dilute sulfuric acid solution can increase the greening rate to 80% without leaving the ice cellar. It can also effectively kill the bacteria in silkworm sand and moth powder attached to silkworm eggs, and has a good disinfection effect.

    In fact, it would be better to use dilute hydrochloric acid solution, but currently 04 Institute can only obtain hydrochloric acid in the laboratory by mixing concentrated sulfuric acid and table salt and heating it. However, the cost of such large-scale preparation is obviously too high.

    First, there is not so much concentrated sulfuric acid.  Although thousands of years ago, alchemists had mastered the method of calcining pyrite or sulfur to produce sulfuric acid.

    But the difficulty of industrial production is completely different, okay?  Zhang Jian and Qu Rukui spent countless brain cells, failed many times, and spent a lot of money to build three tower-like reaction devices, which could barely produce 100 kilograms of concentrated sulfuric acid per day.

    The reason why I say it is reluctant is because the reaction device breaks down from time to time, and each time it has to be shut down for several days for maintenance.

    The uses of sulfuric acid are too wide, and the average daily output of 200 kilograms is not enough to fill the gaps between teeth.  But Zhao Hao told Zhang Jian and the others not to worry, and just provide it for internal use of the research center first.  Run the current preparation equipment for one year, and then consider expanding production capacity after improvements are made.

    So use sulfuric acidWith ??zero new additions, I think we can declare complete victory!  "

    "Haha, it's so exciting Oh no, I'm talking about this Operation Spring Thunder." Wang Shimao coughed twice in embarrassment and quickly changed his words: "Although there was not much movement, it was like a war."

    "I almost scared me to death." Wang Mengxiang also smiled and said: "I'm talking about the cost, which is three hundred thousand taels."

    "How much? Not much." Mr. Zhao was thick-skinned and didn't care about their teasing. He said to himself: "Preventing the spread of the epidemic has enhanced Jiangnan's cohesion and improved people's confidence in the group. It has also established a set of epidemic prevention and control measures.  System, it¡¯s worth a thousand dollars!¡±

    ¡°What you said is true.¡± The directors praised one after another: ¡°No matter how you explain it before, ordinary people didn¡¯t understand what science is, but now everyone knows about science.¡±

    "But we still can't relax completely." Zhao Hao continued to say enthusiastically: "These six counties are free of germs, but other counties still have them, and there is still the possibility of outbreaks. Therefore, the county development companies and Jiangnan Textile must do something  It is better to conduct regular monitoring of silkworm diseases. The earlier we detect and deal with them, the smaller the losses will be."

    "In addition to silkworm disease, the same is true for infectious diseases in humans and animals. I think it is better to establish a special epidemic prevention committee to take charge"

    Secretary Ma was beside him, taking notes quickly, but his heart felt sour.  People also want to kiss, in public (remember the website address: www.hlnovel.com
