1982, November. Pen "Fun" Pavilion www.biquge.info

Hainan, Wenchang.

Because the Jiuquan satellite launch site has become a fortress because it has become a front-line battlefield, the rocket launch site has ceased operation. Therefore, the Wenchang Satellite Launch Base has become the main satellite launch base of the Republic.

Since 1981, China's rocket launches have become more frequent.

In 1981, China experimentally launched an "Iridium-1" communication satellite. This is the first communication satellite of the Iridium communication system, and the future plan is to launch 66 satellites.

The failure of Iridium in the origin world lies in the high cost of satellite communications, so the expensive cost is only for the satellite communication telephone market with only one million users in the market space, and the cost of high shares, and the scale of users cannot be increased to tens of millions of people, so it is a very commercial failure.

However, the republic began to imitate Iridium and launch 66 communications satellites, not primarily to serve users of satellite phones, but to serve swarms of drones on the battlefield. If you can remotely control hundreds of thousands of drone swarms on the battlefield in any region of the world, then this business is very cost-effective.

After all, the military market, even if it is small, is far more profitable than the civilian market.

Moreover, drone technology is still very rudimentary, and in the future, when drones become larger and larger, and can gradually carry more and more ammunition, this service will become more and more cost-effective.

In the year of '82, satellites such as "Iridium 2" and "Iridium 3" were launched one after another, and in November, the latest satellite launched was the "Iridium 12" communication satellite.

After launching a number of satellites in succession, it was natural that the Soviet Union and the United States could not hide it. In the world, Europe, Japan, and other regions have abandoned space technology, including satellites, and space technology is controlled by the United States and the Soviet Union. This is because the Soviet Union and the United States constantly coerced and induced other countries to give up the development of space technology in exchange for satellites of the United States and the Soviet Union to serve other countries.

In addition, the Soviet Union and the United States hinted that if countries engaged in their own space-related projects, the Soviet Union and the United States would stop serving them, so many countries stopped their research on space technology.

A spokesman for the Republic said: "The purpose of these satellites is mainly for communication purposes. Satellite telephones, satellite radio and television and other uses. ”

Both the Soviet Union and the United States were skeptical, but could not do anything. In fact, the Soviet-American satellites really stopped serving China, and it was nothing!

The technology of satellite launch in this world is relatively advanced, but ...... Due to the backwardness of electronic technology, the performance of satellites is not very advanced.

The republic's rockets and satellites are inferior to the United States and the Soviet Union in many technologies, but semiconductor-related technologies are superior. So, the performance of the satellites was better than that of the USSR and the USA, and even if the satellites of the USSR and the USA were no longer serviced by many republics, it would not be a big deal.

In fact, in addition to communication satellites, China subsequently launched the Beidou navigation series, Fengyun meteorological series and other satellites.

Among them, navigation satellites and meteorological satellites need to monitor the earth, so they can also be used as spy satellites.

There are also meteorological satellites, China's meteorological satellites are engaged in both weather forecasting and beta trend forecasting.

In short, at the beginning of '82, the Republic became the third country after the United States and the Soviet Union to have satellites to monitor beta movements.

On the other hand, the Soviet Union and the United States could only downplay this fait accompli and did not say anything more. After all, in the eyes of the Soviet Union and the United States, the republic was also a pain in the ass, launching satellites into the sky on their own, and the lifespan of satellites was only a few or more than a dozen years. At first, it may be very exciting, but after a long time, with China's financial resources, most of them will consciously stop launching satellites and choose the services of the Soviet Union and the United States.

……

During the year, the Republic continued to receive good news, and in addition to the military, science and technology, and industry, the development of agriculture was also very gratifying.

The first is seawater rice, according to the information provided by the traveler, the agricultural workers of the Republic visited Suixi County on the coast of Guangdong Province and found the "Changmao Valley" cultivated locally.

Changmao Valley, which grows in the seaside tidal flats of Suixi County, does not need to be fertilized, sprayed, or weededed, and can be harvested when it comes to the harvest season. However, because its yield per mu is only 300 catties, and the taste is much worse than that of ordinary rice varieties, a bit of the bitter taste of seawater, so its cultivation has been limited to the local area and has not been promoted.

However, the discovery of Changmao Valley surprised agricultural workers, because it proved that salt-tolerant rice does exist, and that it has been cultivated for at least hundreds of years. It's just that the long-haired valley was not taken seriously by the locals, but in order to avoid the waste of the tidal flats by the sea, they planted a little long-haired valley casually.

This long-haired grain is a seawater rice that has been domesticated by humans for a long time. The yield and taste per mu are already a little better than the original seawater rice. After all, seeds that taste too bad have been gradually discarded by humans. Therefore, the salt tolerance of long-haired grain may be a little worse than that of wild seawater rice.

However, the agricultural authors have begun to report to the central government, and after that, they have started to expand the cultivation of long-haired grain. In the coastal areas of Guangdong, more barren land, to promote the cultivation of this kind of long-haired valley, the seed area will exceed 1 million mu.

After that, the staff continued to patiently search according to the information, and sure enough, they found a wild rice species that is taller and thicker than Changmao Valley-seawater rice!

With the discovery of a large number of salt-tolerant rice, there is no doubt that land that could not be used to grow crops will be utilized.

As for the yield per mu is only 300 catties, this is not a thing. After all, it does not need to sprinkle pesticides and fertilizers, and the cost is relatively small. At the same time, domestic agricultural workers have also begun to carry out farm-based planting and operation on the island.

By adopting more mechanized large-scale cultivation, a small number of farmers will plant more salt-tolerant rice varieties such as seawater rice and Changsheng Valley, so that their per capita harvest will not be lower than that of traditional rice cultivation.

In addition to seawater rice, Yuan Longping's hybrid rice achievements have also been vigorously promoted by the state. Of course, hybrid rice belongs to the category of improved varieties.

In addition to the good seeds, the fertility of the farmland, the natural conditions such as light, rainfall, temperature, etc., there are also chemical fertilizers and pesticides!

The most important factor in the increase in agricultural output in modern times is the popularization of pesticides and chemical fertilizers. Fertilizers and pesticides have contributed more to the increase of yield per mu than even more than varieties improvement technologies, including hybrid rice...... Therefore, increasing the production capacity of chemical fertilizers and pesticides can also continue to promote the grain harvest throughout the country.

In recent years, the domestic industrial production capacity has been improved, and the production capacity of pesticides and fertilizers has also been continuously improved. As a result, there has been a continuous increase in food.

And then there is the hydroponic technology (soilless culture)!

That is, there is no need for farmland and light, but directly cultivated indoors, and the crops are not cultivated through the soil, but through the prepared nutrient solution, which contains all kinds of nutrients needed for plant growth. After that, the light is used to adjust the light, and layers of plants are placed in the room where there is no sunlight.

A certain scale of the development of hydroponic technology is the plant factory, in which food is produced, without the need for traditional farmland!

In terms of yield per mu and efficiency, it is easy to achieve a large-scale plant factory with a yield of tens of thousands of catties per mu. Merely...... Hydroponic technology is very strict for the scientific literacy of workers, the management of factories, and the consumption of power resources. Moreover, in terms of cost, hydroponic technology is still much more expensive than the cost of traditional agriculture.

Large-scale hydroponics are all indoors, and in order to better manage them, natural light is no longer used, but indoor lights provide light. In order to control the temperature, it is sometimes necessary to use the air conditioner. In addition, the control of the concentration of nutrient solution and the concentration of carbon dioxide and other gases in the room are all scientific.

To put it simply, this technology is good, but the problem is that it consumes a lot of power!

If it competes with traditional agriculture, even if it has a large production capacity, but the expensive cost makes it compete in the market, it will not be able to compete with traditional agriculture for the time being.

However, the traverser still insisted on this technique...... Because, after the popularization of this technology, if a city is built with high-rise buildings, and all the high-rise buildings are planted factories, the food production capacity of a city can be greater than the production capacity of the farmland of the whole country.

In addition, hydroponic technology can also be used in environments such as the seabed and space. In those harsh environments, traditional agriculture is not possible, but hydroponics can. In the future, the application prospects of this technology are beginning to be considerable!

At present, there is a 300-square-meter plant factory in the Fengchao base in Beijing.

This plant factory uses computers to store all kinds of data during the growth of plants. The staff adjusts the set temperature, humidity, light, carbon dioxide concentration, and nutrient solution.

Basically, the factory is like a science laboratory, and most of the staff are experts in the fields of agriculture, biology, chemistry, and computers.

At present, the plant factory of Fengchao, although it covers an area of only half an acre. But because the plants are like drawer shelves, they are arranged in six layers. At the same time, the density between the plants is also very dense, after all, the roots are stained in the nutrient solution to attract nutrients, and at the same time, the light is electric light......

So, half an acre of space, 10 tons of grain and vegetables a year!

"To put it simply, the future of hydroponic technology is vast!" Zhang Ruohan, who is in charge of agriculture, said with great confidence, "Even if it is an orbital space station to outer space on Earth, it is still an alien planet." When traditional agriculture does not have the conditions to be launched, hydroponics can also be carried out. The cost problem is very expensive now, and a kilogram of vegetables in hydroponics costs 5 yuan, which is more expensive than pork. However, if you simply export to Europe, there is still a profit margin! The market price of naturally grown vegetables in Europe has risen to about $20 per kilogram, and the price of meat has risen to hundreds of dollars per kilogram! Therefore, we are now hydroponic technology, on the one hand, gradually experimenting and expanding production capacity, and reducing costs through large-scale production. In addition, that is, to export to Europe and earn a little foreign exchange! ”

"This kind of field technology is required!" Li Feng couldn't help but say in admiration. (To be continued.) )
