My lifelong pursuit

Is to keep everyone away from hunger

-Yuan Longping

a state scholar of no equal

I have two dreams, one is to enjoy the cool under the grass; There is also a dream that hybrid rice will go global and cover the whole world.

Yuan Longping is a pioneer in the research and development of hybrid rice in China, and the first scientist in the world who successfully utilized the heterosis of rice, and is known as the "father of hybrid rice". Until the beginning of this year, at the age of 9/kloc-0, he insisted on carrying out scientific research in Nanfan Base in Sanya, Hainan.

Do you know the significance that Yuan Longping can stop us from starving?

China is a country with a population of 654.38+0.4 billion, and the daily consumption of grain is very large. In 2065.438+09, the total consumption of bare rice in China reached193.025 million tons.

The time for China people to get rid of hunger in an all-round way is 1987, which is actually about 30 years. However, the United Nations announced that there are still more than 800 million hungry people on earth.

And this data is still expanding, and now international food prices are also rising. It means that many, many people who live on the same earth as us are still hungry every day.

And let the people of China from hunger, is Yuan Longping.

Today, Xiaoyan will take you to Grandpa Yuan Longping, a master of Chinese studies who has kept China people firmly in their jobs.

I. Kensuke

Yuan Longping (1September 7, 930 -202 1) was born in De 'an County, Jiujiang City, Jiangxi Province. Famous agricultural scientist at home and abroad, pioneer and leader of hybrid rice in China, winner of "* * * and National Medal" and academician of China Academy of Engineering.

Yuan Longping is committed to the research, application and popularization of hybrid rice technology, and has established a super hybrid rice technology system, which has made outstanding contributions to China's food security, agricultural science development and world food supply, and is known as "the father of hybrid rice in the world".

Second, the leveling

After graduation, Yuan Longping was assigned to teach at Anjiang Agricultural School in Hunan Province. She stayed in this remote place for 16 years!

In 1950s, Yuan Longping first engaged in the research and teaching of sweet potato breeding, but at that time, the country was short of food, so it turned to rice breeding, which was most needed by the country.

196 1 One day in July, Yuan Longping selected seeds in the experimental field and accidentally found a rice that stood out from the crowd. Spikes are large and full, with as many as 230 grains. After careful calculation, using it as seed, the yield per mu of rice will reach 1000 kg, while the high-yield rice at that time was only five or six hundred kg. To this end, he led the team into the research and development of miscellaneous rice, which lasted for ten years.

"Ten years to sharpen a sword" began with childhood "pastoral dream". 1960 began to study hybrid rice spontaneously in order to "feed everyone". 1970 discovered "wild rice" and 1975 succeeded in seed production. The rice yield in China has increased from 200 Jin per mu before liberation to 600,700 Jin, and now the super rice is 1000 Jin ... It is this "sword" that ended the history of China's dependence on food aid.

1980 hybrid rice cultivation technology was transferred to the United States as the first agricultural patent technology in China. Yuan Longping was hired as the chief consultant of FAO, and went to the United States, Vietnam, India, Myanmar, the Philippines, Japan, France, Britain, Germany, Egypt, Australia and other countries to teach technology and guide the development of hybrid rice. More than 50 international training courses on hybrid rice have been held at home and abroad, and about 2000 government officials and agricultural experts from more than 40 developing countries have received training ... At present, the annual planting area of hybrid rice abroad has reached 7 million hectares, which is generally more than 20% higher than that of local rice. ...

Step 3 dream

I have a dream, which is budding in my heart.

"The dream of enjoying the cool under the grain" and "the dream of hybrid rice covering the whole world" are Yuan Longping's lifelong dreams. The former is his dream. He once dreamed that the super hybrid rice in the experimental field was taller than sorghum, with ears as long as brooms and grains as big as peanuts. He and his assistant sat under the ear of rice to enjoy the cool. With the continuous high yield of super rice, this dream has gradually become a reality. The latter hopes that super rice will go abroad and contribute to world food security.

Fourth, hobbies

It is often said that it is great to do one thing to the extreme.

But Yuan Longping has many unexpected talents besides studying hybrid rice.

He himself said: hobby is freedom, and specialty is rambling.

During my school days, I often skipped classes to go swimming and fluttered in the Yangtze River.

16 years old, champion of Hankou freestyle 100 meters, champion of 400 meters in Hubei Provincial Games.

Besides being a good swimmer, Yuan Longping is recognized as the "Prince of Volleyball".

In his 80 s, he often jumps all over the court and smashes with one hand.

In addition to sports, Yuan Longping also has a "tall" hobby-playing the violin.

Whether working alone in remote mountainous areas or working hard in the fields.

Whenever he has time, he never forgets to pick up the violin and play a melodious tune, which brings confidence and courage to himself.

He once played "Serenade" on the violin at the New Year's party of the company, and also publicly played "It's Hard to Walk" by Li Siguang at a national conference.

When the reporter asked him, "Do you think you are handsome?"

He replied wittily: "I am handsome!"

Did you see a different Yuan Longping?

Three meals a day, the rice is delicious, and people who are full should always remember Yuan Gong. Every day after that, eat well and don't waste a grain; Live a good life and cherish every moment; One more time: "Bon voyage, Grandpa Yuan Longping".

In the future, you will be the one who says "bumper harvest in rice fragrance" every year.

Every wisp of rising kitchen smoke in the future
