Chapter 146 Automatic Rice Cooking Pot Many things in Zhoujiazhuang seemed new to Zhang Jianshe, so he went for a walk. For example, he was quite surprised by the practice of "borrowing land" from dried-up rivers and mountains. In fact, the reason why my country is short of food at this stage is due to drought on the one hand, human factors on the other, and the fact that a lot of land in my country is not being used reasonably. The country has actually also noticed the latter, so starting a few years ago, it has mobilized millions of people to reclaim the Great Northern Wilderness. The scope of the "Great Northern Wilderness" is basically within the territory of Heilongjiang Province, including the Sanjiang Plain, the Songnen Plain, the foothills of the Wanda Mountains, and large tracts of wasteland to the north and south of the Lesser Khingan Mountains. It was the plan of "reclaiming the Great Northern Wilderness" that gave China an important granary - Beida Granary. Beida Granary played an indispensable role in my country's self-sufficiency in grain. Today's "Great Northern Wilderness" is mostly composed of meadows, swamps, and partial forests. It has abundant atmospheric precipitation, with an average annual precipitation of more than 500 mm. The summer sunshine hours are long and the temperature is high, which is very conducive to the growth of crops. It is one of the three major black soil belts in the world. Of course, when it is cold, it is really cold. The average temperature in winter is around minus 30 degrees Celsius, and it is known as a frozen world. In fact, that piece of land had been paid attention to at the beginning of the founding of the People's Republic of China. In the early stage, it was soldiers who quietly cultivated it. Many people could not imagine the difficulties at that time, such as the lack of houses. Some people may say that not having a house is not a big deal, just build one, how hard can it be?

It takes time to build a house, right? During this period, you will inevitably have to sleep in the open air, right? Let alone the temperature and other factors, just the wild animals around you, if you don't keep an eye open at night, you may be taken away. There are far more beasts than people. At that time, the pioneers had to work more than twelve hours a day, and they had a Sunday every ten days. No matter how tired they were, no one complained. "You want polyethylene film?" Zhang Jianshe heard what Zhou Yimin said and seemed to be very eager for that thing. "Yes! With that thing, we can grow crops in winter." Zhang Jianshe is not an agricultural researcher, so he doesn't know much about it, but he does have some basic knowledge. Covering with polyethylene film can increase the temperature, but it should not reach the temperature required for plant growth, right? Besides, in addition to temperature, plants also need water, sunlight, carbon dioxide, etc. to grow. He thought that perhaps Yimin had some other tricks, so he didn't rush to question it. "I have a friend who works in a polyethylene factory. I'll contact him for you and try my best to get you a batch." When Zhou Yimin heard this, he was overjoyed and thanked him repeatedly. I was so sleepy and someone gave me a pillow. "Thank you, Uncle Zhang!" Polyethylene film is available in stores, and it is not expensive. However, Zhou Yimin needs a reason, just in case, when others check it out, the source of the thing must be known. If it is something you eat normally, it doesn't matter if you take it out. If you eat it, there will be no evidence anyway. But this thing is easy to be caught by others, so it is best to have a source. Zhang Jianshe laughed and scolded, "Why are you thanking me? You are really asking for a fight." At around four o'clock in the afternoon, Lu Guofu arrived. Just then, the children started to go home from school. The old Party Secretary sent people to help Projectionist Lu set up the scene, such as setting up the screen. At the scene, the first few rows were already filled with chairs, and the chairs of the students in the classroom also came in handy. "Uncle Lu, the generator is here." Zhou Yimin came over carrying the generator.

"Okay, put it there." The generator doesn't need to be placed so close, as it will be a bit noisy when generating electricity, affecting the viewing experience. The generator can be placed farther away and connected to the power supply with wires. After Lu Guofu finished fixing the machine, Zhou Yimin invited him to sit at his home for a while, as the evening meal would be ready soon. As for these machines, the old branch secretary specially assigned someone to guard them to prevent the naughty children and others from getting close. If someone damaged someone else's machine, their village could not afford to pay for it. "Uncle Lu, can we come here to show a movie once a month?" Zhou Yimin asked as he walked. Lu Guofu agreed without hesitation: "Okay! I can't guarantee the specific date." He also believed that Zhou Yimin would not let him work in vain. "Uncle Lu, you decide." Zhou Yimin said happily. The old party secretary and other villagers who followed behind were extremely surprised after hearing this. Doesn't that mean that in the future, their village will be able to watch a movie once a month? Who dares to think about this? Even the Red Star Commune can't guarantee that a movie will be shown every month. They have to achieve it first in Zhoujiazhuang. When he arrived at Zhou Yimin's house, Lu Guofu first went to say a few words of blessing to the old lady. He came to show the movie mainly for the birthday boy. After blessing, he drank tea with everyone. His eyes involuntarily fell on the certificate and the newspaper on the wall. He was amazed and the topic of conversation inevitably turned to Zhou Yimin's invention. Speaking of inventions, Lu Guofu said to Zhou Yimin a little helplessly: "Yimin, you don't know, after you left yesterday, my two little brats were thinking about inventions there, and they were almost crazy." Zhang Jianshe smiled and said, "It's great that children like to invent things! We should encourage it." As a scientific researcher, of course I hope that children will like inventing and researching! "Inventions should of course be encouraged, but they can't be too fanciful!" Lu Guofu smiled bitterly. Zhou Yimin was curious: "What do they want to invent?" From what he heard, it seemed that those two guys had very advanced ideas. "They watched their mother cook, so they said they wanted to invent a pot that could cook rice automatically. If that's not a fantasy, what is it?" Wow! A pot that cooks rice automatically, is that a rice pot a spirit? After these words were spoken, Zhang Jianshe and Zhou Yimin were stunned. Zhou Yimin immediately thought of the rice cooker. Isn't that a pot that automatically cooks rice? As a time traveler, he has played around with rice cookers of various functions in the future. As far as he knows, the structure of an electric rice cooker is actually very simple, not as difficult as imagined, and cannot be considered black technology. Moreover, this thing has already been invented. The world's first electric rice cooker was invented in 1950 by the Tokyo Telecommunications Engineering Company of the small-time Ibuka Masaru. The original design of the rice cooker was quite simple, operated by a single button, and the pot was made of aluminum. Since then, the appearance design of this mechanical rice cooker has also changed a lot, and prints and cartoon patterns have been added to the original white rice cooker body. By 1955, Toshiba had developed an electric automatic rice cooker, which was a truly mass-produced rice cooker. In 1960, which was this year, Panasonic produced its first automatic heat-keeping rice cooker, which was the first rice cooker with a heat-keeping function. In the same year, rice cookers with a timing function also began to be produced and sold, marking the entry of rice cookers into the electronic control era. Zhang Jianshe laughed and said, "That's an electric rice cooker, invented abroad."

It was Lu Guofu's turn to be surprised: "Ah! Is there really such a thing?" (End of this chapter)
