Why do rice seeds that cannot increase production come here?Ding Ying wrote her discovery into a paper "Guangdong Wild Rice and New Species Breeding from Wild Rice", and then forgot about it.

Now Ding Ying is in the Department of Agronomy of the Academy of Engineering, and she is more concerned with studying the effects of light, heat, water, and fertilizer on rice yields, and dividing the rice-growing belts in southern China.

Tang Hua: "Mr. Ding, you have done research before and proved that Chinese rice is derived from wild rice in southern China. So, have you ever thought that rice after hybridization does not increase in yield like hybrid tobacco and hybrid potatoes? Really? The reason is that the genetic relationship between bamboo sticky rice and "rhinoceros tail" is too close, so the yield-increasing effect of hybrid species cannot be seen?"

Ding Ying: ...

Chapter 88, Thomason's South Sea Crusoe

"Committee Ding, if Dean Tang's specific suggestion pointed out the direction, it must have a deep meaning, and development in this direction will definitely achieve results."

In the last meeting of the first general meeting of the Academy of Engineering, committee members from all faculties gathered together.When Wang Dayan heard Ding Ying say this, he immediately regained his spirits.

In 1951, he and Tang Hua dismantled a primitive Soviet night vision device, and the domestically produced night vision device was used in North Korea in the second year.Then came the current "non-contact mask" lithography machine in 52. This seemingly incredible machine was finally produced.

Zhao Zhongyao: "Committee Ding, have you written down the few words Dean Tang told you?"

Ding Ying: "I copied it all down, without missing a single word."

Zhao Zhongyao: "That's good. President Tang has a natural intuition about the direction of scientific and technological development, and so far his intuition has been correct."

Ye Zhupei: "At the end of 1952, I proposed to my superiors to carry out research on top-blown oxygen converter steelmaking technology in China. It was Minister Tang who asked the heavy industry department to give full support, and also asked me to use a blast furnace and a flat furnace in Shijingshan Iron and Steel Plant for experiments. Now we have successfully broken through this technology, which will be of great help to our country's steel industry."

Mr. Ding's current work unit is Sun Yat-sen University, and he only spends time in the rice fields in the south on weekdays, and hardly comes to Beijing.This time when he came to Beijing for a meeting, he was taken aback when he heard these well-known committee members unanimously say that the direction pointed out by Tang Hua was very important.

"Yes, yes, the Department of Agriculture has applied for the allocation of manpower and resources to my side. When I return to Guangzhou, I will organize a rice seed inspection team to conduct detailed rice inspection. I will also restart the research on hybrid rice."

……

Crop hybridization technology was first tried in the 18th century. Kerroyt's tobacco hybridization experiment also yielded a tobacco variety that could significantly increase yield. In 1860, Mendel discovered the law of heredity, and more and more people tried to crossbreed.But crop hybridization mainly depends on the personal experience and feeling of scientists, which is a matter of constant experimentation and luck.

I have encountered countless times so far, and obtained several varieties that can effectively increase production, but there are also some species that have tried almost all possibilities, and none of them can increase production, so I put a "non-hybridization" in the crop code. Tag of.

Some people have also tried rice, except for Ding Ying who has tried, and the Japanese have also tried, but they have not been able to breed varieties that can significantly increase yield.

The Japanese are probably thinking that if they fail to breed hybrids with increased yield after a few more attempts, then the rice species can also be labeled as "non-hybrid".

The principle of hybrid rice has been determined by Mendel. In fact, the job is to try, keep trying, try with purpose, and find as many rice species as possible.

Since it is a long process of searching and trying, the earlier the start, the earlier the date of success may be.

Zhongsha Islands, waters near Huangyan Island.

The tank landing ship 908 of the Navy's South China Sea Fleet and the frigate (US-made escort destroyer) "Putian" set off from Guangzhou. After three days of sailing, they saw small buildings standing on Huangyan Island.

In June 1953, in view of the U.S. Navy’s expansion of the Subic Bay Naval Base in the Philippines, our Navy Command ordered that the Marine Corps send a small detachment to occupy the reef of Huangyan Island, and immediately start construction work on Huangyan Island as soon as possible. A fortress building with a steel-concrete main body, a radar station and electronic reconnaissance equipment that can be installed and a certain degree of defense is built on the reef.

"Throughout 1954, a quarter of the South China Sea Fleet's engineering force and half of its infrastructure funds were invested in Huangyan Island. This is not a small price."

On the "Putian" frigate, Lian Chang, the frigate's deputy detachment leader and formation commander, used binoculars to look at the small spot on the sea surface a few nautical miles away.

The captain of the "Putian" also said with emotion: "I have been patrolling here for two years, and it is amazing to see a four-story building growing out of the sea. We are like building a sentry box outside the US base."

In August 1953, soldiers from a squad of the Marine Corps carried simple materials to a reef on Huangyan Island and built two stilt houses here.

In the four sheds made of rebar and moso bamboo, five soldiers in each shed persisted on Huangyan Island for three months, relying on compressed dry food, canned food, fresh water stored in oil barrels, and rainwater from the rain.

Three months later, the landing ship came, and the exhausted marines were withdrawn and replaced with new infantry squads of the marines.

300 meters north of the bamboo stilt house, from October 1953 to May 10, there were always engineering teams and transport ships working there.It took more than a year just to build a four-story reinforced concrete building. A typhoon in June 1955 caused a lot of damage to the construction site. An engineer died (missing) and a lot of accumulated building materials were blown away.

Now the main structure of the building is finally completed, and the Marine Corps commanders stationed in the stilt house can finally move to the concrete house.

……

The "Putian" and the 908 ship passed Huangyan Island and continued south without stopping.Their task this time is not to inspect the vicinity of Huangyan Island, but to search south.

The goal is for the Prime Minister to listen to the mysterious islands of the Nansha Islands mentioned many times by the pilots and crew of Indonesian Airlines when he returns from Indonesia after the Bandung Conference.

This island is said to be mysterious, but it actually has a name: Nanwei Island.

In 1953 and 1954, U.S. Navy planes actually flew over the island and found that there seemed to be residents on the island, as well as fishing boats.

During the Bandung meeting, the special planes of the Prime Minister and the delegation stopped in Jakarta, and the pilots communicated with Indonesian pilots. They mentioned many times that there are many islands in the South China Sea with residents.A pilot said that there are still warships moored on Nanwei Island.

Are there warships moored?The U.S. Navy has a huge base in Subic Bay, and its warships will not berth in trails like Nansha, where there is no underground fresh water.It is impossible for Malaysia and Vietnam to enter the Nansha waters now.

In order to verify the strange incident encountered by Indonesian pilots, after the Prime Minister returned to China, the Air Force took off two Tu-4s from Guangxi, and flew directly to the Nansha Islands for close reconnaissance with slightly crude navigation equipment.

Then, there was a trip to the southern tip of the Nansha Islands by the "Putian" and the 908 ship.

Since the second half of 1953, the navy's engineering forces in the South China Sea have all been concentrated on the construction of Huangyan Island, Yongxing Island and Taiping Island.Huangyan Island built a building on top of the stone, which is technically difficult; Yongxing Island and Taiping Island need to build small airports, and the investment in manpower and financial resources is relatively high.

To be honest, the navy can only build three islands in the South China Sea at the same time, and cannot spare the strength to start the fourth construction project at the same time, but Nanwei Island has to go and see.

……

It takes three days from Guangzhou to Huangyan Island, and more than two days from Huangyan Island to Nanwei Island.

"Detachment Captain," the captain of the "Putian" asked Lian Changxian, "Our two small warships are just walking around the South China Sea so swaggeringly. Does the United States have no intention of doing anything at all?"

Lian Changxian: "Although the United States hates China to death, it still doesn't have the courage to fight directly."

"But I find it strange that our South China Sea Fleet directly faces the U.S. Navy, but why are all the large warships, especially those equipped with missiles, in the North China Sea Fleet and the East China Sea Fleet, while the South China Sea Fleet does not have a large destroyer, but a destroyer frigate with missiles None, it's all artillery."

Lian Changxian: "I guess what the central government means is that if the South China Sea Fleet needs to change their outfits, they should do so as a whole, so as to increase their combat effectiveness to the peak at once, instead of changing their outfits one by one. Therefore, the South China Sea Fleet must be patient. Moreover, after the construction of the two airports on Yongxing Island and Taiping Island, our power in the South China Sea will be greatly enhanced."

The formation arrived near Taiping Island, did not call at the port, and continued to travel southwest.Nanxun Reef, Xiaonanxun Reef, Daxian Reef, Yongshu Reef...

Those located in the Jiuzhang Reefs of the Nansha Islands are called reefs, not islands, which means that they have no place for people to live.Some reefs can expose a sharp stone on the water surface when the tide is high, while some reefs are completely submerged when the tide is high.

To the southwest of Jiuzhang Reef is Yinqing Reef. The formation first saw Cuarteron Reef, then Middle Reef, East Reef, West Reef, and then Nanwei Island.

The Indonesian pilot is right, there are residents on Nanwei Island.Even Chang Xian and the lookout saw a puff of cooking smoke rising from the island.The formation continued to approach.

"Look, what's that? A destroyer!"

"Not one, but two!"

The bridge of the "Putian" was boiling.

"There are two ships, one of which is already half sunk, probably sitting on the shallow seabed. The other is a US-made escort destroyer...it seems to be at the same level as ours."

It turned out to be an escorting destroyer. The formation began to prepare for battle. The landing ship moved to the rear first. The three 3mm naval guns of the "Putian" were activated, and the muzzles pointed at the shadow of Nanwei Island.

Get a little closer, and the shadow of the ship on Nanwei Island is still motionless.When approaching 3 nautical miles, Lian Chang first saw through the telescope that there was a problem with the destroyer escort:
