Rebirth to 90s: Start from Scratch

Yuan Pengchi pondered for a while and said, "I don't know much about machinery and heavy industry, so I dare not jump to conclusions in this regard."

"But as far as I know, in our country, almost all agricultural machinery at present, excluding tractors, are imported."

"Mr. Zhang, if you want to buy from abroad, the problem is not big, but the parts and repairs after damage are required, and people are required to open these machines."

"The current farmers in our country simply do not have this ability."

"In other words, if you give it to the machine, they can't open it. If they learn to open it, they can't fix it even if there is a problem."

"Small problems can be fixed by a few masters, but for larger problems, those masters in rural and urban areas can hardly repair them."

"It's not good to say that even if you go to the capital city, you may not be able to find a suitable repairman. Everyone has never seen this machine."

"Even if you encounter a powerful master, you will repair it after a few tossings, and there are no parts in China."

"All in all, with mechanized production, our biggest problem is people, it's machinery."

"Even if our country does not have the capability of R&D and production, it must at least have the capability of use and maintenance."

Zhang Qianxiu was a little stunned, and said, "Professor Yuan, what do you mean is that when we develop agriculture, we must first develop industry?"

"That's almost what I mean!" Yuan Pengchi said: "At present, the country with the highest mechanization in the world is the Soviet Union, and the second is the United States. The heavy industries of these two countries are very powerful.

"I would say a digression, heavy industry is the foundation of a country, and light industry is the economy of a country. Whether our country is heavy industry or light industry, it is still in its infancy."

"The country actually wants to develop agricultural mechanization, but if it doesn't solve the basic problems of heavy industry, agricultural mechanization will have many difficulties. From production to maintenance, we rely on foreign countries. If we only use and maintain daily maintenance, we may not be as good as farmers. Farming with both hands is more cost-effective."

Zhang Qianxiu only fully realized a problem at this time. Basic industries can't develop, and what you want to do will be difficult.

Yesterday Zhang Qianxiu chatted with Tian Shuyuan and found that the domestic high-tech fields are everywhere suppressed by foreign countries. Today, chatting with Yuan Pengchi and found that even the most basic ones are being constrained.

Even if you buy a machine, there is no way to repair it if there is a problem, how helpless!

Zhang Qianxiu couldn't help sighing, and suddenly felt a little dull. He couldn't go into heavy industry anymore, and he didn't have that much energy.

Do chips, agriculture, and heavy industry. When he goes to heavy industry, he finds that the materials are not up to standard. Is he going to engage in steel smelting again? To research new materials? After working on materials, I found that the required machinery and technology were all backward, so I couldn’t do it again.

Zhang Qianxiu thoroughly realizes that this is an endless loop, one link after another. You will find in any industry that your previous industry has been surpassed and constrained by foreign countries.

Zhang Qianxiu couldn't help asking: "Professor Yuan, can I ask a presumptuous question?"

Yuan Pengchi said: "Mr. Zhang ask!"

"What is the use of agricultural research in our country?" Zhang Qianxiu finished asking, and said, "I didn't mean to offend. I'm just curious about what agricultural research does."

Yuan Pengchi explained: “This world is an ecology. What we do in agricultural research is to make all kinds of crops higher yield, better taste and healthier without destroying the ecology.”

"Mr. Zhang, don't underestimate a seed. You are talking about good seeds. In fact, this is a process of cultivation."

"Do you know what wild corn is like? That is, corn that grows naturally in nature."

Although Zhang Qianxiu is a rural person, he really doesn't know what wild corn is like. He shook his head and said, "I don't know!"

Yuan Pengchi stretched out his index finger: "It's just that big. Farmers leave the fullest as seeds. Each generation picks the best. Gradually, the corn grows bigger and bigger, and it becomes what we see now."

"Almost all crops we see, wild varieties and our cultivated varieties are very different, some you don't even know, this is actually a certain kind of crop that we often eat."

"What we study in agriculture is to cultivate our current crops to produce higher-yielding varieties. This involves more than just selecting large-grain seeds."

"We also need to study the relationship between various insects, small animals and plants."

"We also need to study the pathology of various plant diseases, and what methods can be used to contain, improve, and treat them without affecting the yield of crops. The solutions must not be harmful to the people who eat them."

"Then study the soil and so on."

"In short, it is the sentence I said before. The purpose of our agricultural research is to do everything possible to increase the yield of crops and improve the quality of crops."

Zhang Qianxiu suddenly thought of a question and asked: "Professor Yuan, do all the things we eat now have new varieties?"

Yuan Pengchi said: "There are new varieties, and there are different varieties."

"How did these varieties come from?" Zhang Qianxiu asked.

Yuan Pengchi said: "Not to mention genetic technology, we basically rely on plant mutations to develop new varieties, and then collect their seeds, and continue to seed and cultivate them."

"Mutations include natural mutations, but it takes a long time; for relatively short-term mutations, induced mutations are thought to use the external environment to affect the growth of plants. There are physical and chemical aspects."

"Chemical mutagenesis, nuclear radiation mutagenesis, light mutagenesis, and these have different branches."

"When we want a crop to undergo mutations, we can choose natural mutations and induced mutations."

"Natural mutations don't need to be explained, they are gene mutations in the natural environment."

"Induced mutations, we can use chemicals to stimulate, or use appropriate amounts of nuclear radiation, light, etc. to stimulate genetic mutations in plants."

"We can use different light for light mutagenesis, such as laser. The wavelength and power of the light have an impact on plants, as well as the time of light."

"Like us, you may be able to cultivate many varieties in a lifetime, but having a good variety is already very good."

Zhang Qianxiu asked: "The same goes for animals?"

Yuan Pengchi said: "In terms of animals, crossbreeding is more common. For example, pigs. There are many breeds. The offspring of two different breeds of pigs are crossed. It is possible that the first two pigs have shortcomings, but their offspring can combine their advantages. ."

Zhang Qianxiu thought of a problem. In his previous life, he always felt that he couldn't eat the taste of his childhood. Pork, chicken, vegetables, etc., seemed to become unpalatable, but the output was greatly increased. Perhaps it was his own past. The edible variety has long since disappeared, and it has become an improved variety.

The improved varieties have increased the yield, but the taste has changed.

Zhang Qianxiu's conjecture is correct. It is the simplest white radish. After the 21st century, there will be almost no species of the 90s.

Not only white radish, but also cabbage, rice, carrots, corn, etc.

Although they all look the same, the seeds are all mutagenized, and then carefully cultivated in the experimental field for several generations, and then marketed and planted on a large scale.

Not to mention the pork. The original native pigs might grow a catty of meat when fed five catties of feed, and at most one or two hundred catties will grow, and the lean meat is only 20%. Later pigs can be fed with two catties of feed. One catty long can have more than 50% lean meat.

Gradually, those native pigs are no longer raised. They are basically the three-yuan pigs they often call, and the three-yuan pigs are actually imported pig breeds.

Later, the country began to protect local pig breeds to avoid extinction, but everyone cares about technology and entertainment. Few people care about these things. Except for the employees, no one cares about the seeds of the crops or the type of pork they eat.

This is why, when you go to the supermarket to buy meat, some are 20 yuan a catty, but the local pork costs 50, 60, or even 80 to 90.

The seed technology of Israel was one of the best countries in the world. They have been constantly cultivating new seeds. Their seed technology will be so powerful. The big reason is that their country’s desert area has reached 67%, and there is a serious shortage of arable land. And freshwater resources, their official support for agriculture is very strong.

The country has such a wide desert area, but 95% of their food is produced by themselves, and only part of their food cannot be grown for local climate reasons. They also export large amounts of flowers, vegetables, and fruits to Europe every year.

Later, in the development of aerospace and aviation in China, I often saw news about bringing all kinds of seeds into space. In fact, they were using the special environment of space to mutate the seeds, and then selecting excellent mutated varieties for large-scale promotion and planting.

After Zhang Qianxiu heard what Yuan Pengchi said, the idea of ​​developing seeds came to his mind: "Professor Yuan, is this mutagenized seed harmless to the human body?"

Yuan Pengchi smiled lightly and said: "Mutation breeding is actually very uncertain, because mutation is unpredictable, but there is still a certain difference between plant mutation and animal gene mutation, and if it can be promoted on a large scale, it must not be. What will be the problem."

"Furthermore, even if the rice is planted in one's own land, mutations may occur."

"Didn't Emperor Kangxi discover a high-quality and mutated ear of rice that year, and finally brought it back to cultivate and cultivated high-yield rice?"

Zhang Qianxiu tentatively asked: "Professor Yuan, if we vigorously develop seed technology, can we also greatly increase production?"

Yuan Pengchi nodded: "This is affirmative. At present, all countries in the world that are capable of doing research in this area are cultivating new seeds. But I also said before that there is uncertainty in seed mutations, and it takes a lot of trial and error to Cultivate a good variety."

Zhang Qianxiu and Yuan Pengchi talked until the afternoon, and the chat with Yuan Pengchi made Zhang Qianxiu feel that his trip was not in vain.

The ones that Yuan Pengchi studied were things that would never be understood in a lifetime.

Zhang Qianxiu felt that his grain and oil business plan had to be corrected again. Although he was a rural person, he only discovered after talking with Yuan Pengchi that he was at most a person who had seen farming and did not understand agriculture at all.
