"The commandos and the left-behind comrades in the base camp are descending. Please prepare two stretchers for the comrades in the base camp at 7000 meters."
"The commando descended to the base camp at 5200 meters!"
May 5, May 28.The four members of the commando went down the mountain safely, and then all entered the hospital.
Liu Lianman suffered rib fractures, multiple muscle and ligament strains, and slight internal bleeding.Qu Yinhua went into the operating room and removed the musculature of 10 toes and heels.Wang Fuzhou and Gongbu were not much better, and had to be hospitalized for a long time to recuperate.
Originally, Tang Hua believed that China would show off the technology of geostationary communication satellites to the world when it reached the summit of Mount Everest.
Now, Tang Hua feels that China is first showing off its willpower to the world, and secondly showing off its satellite technology.
Maybe many years later, other countries will also launch geosynchronous satellites, and there will be satellite live broadcasts. Of course, China will have stronger communication and space technology at that time.But I am afraid that no mountaineering team from any country can have such spirit and spirit, and use their lives to fight for the final victory under such difficult and dangerous conditions.Not now, nor ever.
……
Hainan, Sanya Nanhong Farm.The First Experimental Base of Rice in the Department of Agronomy, Chinese Academy of Engineering.
"Minister Deng."
Tang Hua took the Beijing-Guangzhou line all the way to Guangzhou, and from Guangzhou to Sanya by boat, when he landed, he saw Deng Zifei who came to pick him up.
Deng Zifei is now dressed as a farmer, with shorts, short sleeves, a straw hat on his head, and rubber sandals under his feet.What's even more different is Deng Zifei's mental state. Now he is full of energy and his eyes are shining, as if he has found gold and silver.
Looking at Deng Zifei's current state of mind, Tang Hua felt that the first base should be on track.
"Minister Deng, is it obvious that this crop of hybrid rice has obviously increased production?" Tang Hua asked.
"Of course, I also plowed the fields when I was a child, and I can tell at a glance."
……
Experimental base, June 6.
There is still more than a week before the early rice harvest of the three-season rice. The rice in the experimental field is already full of grains and thick ears, and clumps of clumps are swaying in the paddy field with the wind.
"Hi Minister Tang."
"Hello, Researcher Zhang." In front of Tang Hua, Zhang Xiancheng, one of the four kings of the National Science and Technology Progress Award in 1981 - one of the four kings of the hybrid rice cooperation group, ranked third. (The first of the Four Heavenly Kings is Yuan Longping)
"The specific yield can only be determined after two or three weeks when the rice is harvested, dried and weighed," Zhang Xiancheng said. look."
Tang Hua: "If the growth rate is indeed this figure, then it can be said that the hybrid rice project has achieved initial success."
Now, using only chemical fertilizers to stimulate, at the point where the ratio of fertilizer to cost is the highest, grain production can be increased by about 20% compared to before.Increasing the amount of chemical fertilizers will increase the yield, but the rate of increase will start to slow down. For example, if the amount of chemical fertilizers is doubled, the yield will only increase by 25% to 30%.
Of course, if grain prices rise a little bit, farmers may also be willing to add chemical fertilizers.If nitrogen, phosphorus and potassium compound fertilizers are introduced, it will be easier to increase production.
But there is always a limit to the efficiency of chemical fertilizers.
If chemical fertilizers are added to hybridization and applied to the field of rice cultivation at the same time, then the rice yield will have a terrible increase...
Zhang Xiancheng: "It would be great if Mr. Ding was also at the base, and let him watch the harvest of the good seeds we cultivated with his own eyes."
Tang Hua: "Mr. Ding will stay in the hospital for a while in Beijing, and he has been arranged for a minor operation. ... Next, what are your plans for the development of hybrid technology?"
"Improve the current seed model of the three-season hybrid, and then expand the planting to promote the hybrid rice. In addition, Yuan Longping from Hunan once proposed that the second-line hybrid of rice hybrid is not impossible. I think, our research direction in the next stage , is a two-line hybrid."
There is basically no problem... There is no need for Tang Hua to forcefully change the direction of the car.
Tang Hua: "This research roadmap is very reasonable. Just follow it. ... Yuan Longping from Hunan? Oh, which farm is he on?"
Zhang Xiancheng: "The second base is the experimental base of Anjiang Agricultural School in Hunan Province. Yuan Longping is a teacher of Anjiang Agricultural School. In 57, Ding Laola joined the project team, and by the way, Anjiang Agricultural School was also included in the Department of Agriculture. The experimental base."
"It's really good. I have to go to the second base when I have time. But for now, let's go around Hainan Island first."
When the hybrid rice is harvested and weighed this season, it is also a way to see how Hainan Island is doing.
The scale of iron ore development in Shilu, Hainan is much larger than that in the original historical plane. This is the result of the rapid expansion of several factories of Shanghai Iron and Steel Co., Ltd. and the commissioning of the new Maanshan Iron and Steel Factory.
In Changjiang, where the Shilu Iron Mine is located, a small resource-based county town based on mining has been formed.Of course, Shilu Iron Mine has been developed on a larger scale, so its iron ore will be exhausted earlier than in history.
It doesn't matter, when the Shilu Iron Mine is hollowed out, there will be more iron ore with higher grades to fill it up.
From Sanya to Changjiang, from Changjiang to Haikou, it circled a semicircle, from the southernmost point of Hainan Island to the northernmost point.
Haikou is also a county now...
Now, Tang Hua has to circle another 30 degrees clockwise from Haikou to Wenchang.
Tang Hua is not an expert in agronomy. When he came to Hainan Island, he just watched the excitement at the rice experiment base. Wenchang was the place he really wanted to investigate during this trip.
Chapter 18, buy a ticket to hitchhike to space
Hainan is currently the second largest island in China.
地处热带，大致在北纬18度到20度之间。太原位于北纬37~38度，酒泉位于北纬39~40度，西昌位于北纬28度附近。
In the 70s, China gnawed out a railway in the mountains in southwestern Sichuan, leading to Xichang, and built a satellite launch center here, considering that it would be easier for launch vehicles to enter orbit in low-latitude areas.
However, in the 70s, in addition to considering latitude, China's launch bases also had to consider safety issues.During the Vietnam War, U.S. aircraft carrier-based aircraft flew into the airspace of Hainan Island every day, and China posted more than 300 diplomatic protests in newspapers.
In the end, we can only choose a relatively southerly place in the southwest region, that is, Xichang, to build a space launch center.
"Hainan District is now the outpost of southern Xinjiang's national defense. The Air Force and Naval Air Force have bases on Hainan Island, as well as early warning radars, anti-aircraft missiles, and naval docks. Even I, the secretary of the district party committee, are now concerned about sea and air security, aviation control, etc. The nouns are familiar."
Huang Kang and Tang Hua, secretary of the district party committee of Hainan District, Guangdong Province, are in Wenchang, overlooking a large piece of wasteland near the seaside.
The development of infrastructure in Hainan was accelerated after the establishment of the province in the late 80s. Wenchang in 1960 was not generally desolate.
The main industry in Hainan now is the planting of tropical cash crops, followed by mining and fisheries.In the past 10 years, Hainan has built a good-quality road around the island and two small hydropower stations. Other than that, there are no major projects. Haikou is now a prefecture-level city, but the urban area and construction level are about the same as those in the north in this era. The county seat is about the same.
Tang Hua: "With these naval and air force garrisons, Hainan's sea and air safety can be guaranteed. Safety is also the top priority of the Space Launch Center."
The naval dock in Sanya is being expanded, and Sanya will be one of the main naval bases of the South China Sea Fleet in the future.Now the main bases of the South China Sea Fleet are still in Guangzhou and Zhanjiang. After the delivery of the Type 58 destroyer and Type 59 cruiser in the future, the berth will probably be moved here, which is convenient for security and confidentiality, and is closer to the South China Sea.
The HNA base in Hainan houses early warning aircraft, maritime patrol aircraft, electronic reconnaissance aircraft and electronic warfare aircraft, and two air bases house bombers and fighter jets.
From the establishment of the maritime and air strategic thinking of regional anti-intervention in 1953 to the present, the maritime anti-intervention system has been initially established. It is actually not easy for the US military to force the air force to conquer the cities of Guangdong or Hainan.
Huang Kang: "Hainan is very safe. I haven't seen Americans sending planes to harass me in the past few years. If our Chinese artificial satellites are launched from Hainan Island in the future, then our Hainan will be well-known throughout the country."
"Hainan is now well-known throughout the country," Tang Hua said with a smile, "China's first large-scale rubber production area, as well as coffee and sugar, all of which are high-value cash crops."
"Don't mention it, the yield of rubber trees planted in 51 and 52 was not high enough, and now I am hesitant to change them."
Tang Hua: "If the space launch center is located in Wenchang, it will not only increase Hainan's reputation, but also promote Hainan's infrastructure construction, industry, and urban construction. At that time, many people will come to Hainan Island. There are comrades from the Soviet Union... In short, a lot of houses must be built."
……
If the launch vehicle must be transported by rail, its diameter cannot be greater than 3.4 meters, otherwise it will be super wide.Unless, like the Soviet Union, one bites the bullet and builds a special railway with bridges and tunnels with unlimited dimensions from the rocket factory to the launch center.
