Let the Chinese hold the Chinese rice bowl firmly

16 October is World Food Day
.
In autumn, the rice is fragrant
.
From northeast to southwest of China, from North China and the Huanghuaihai region to the middle and lower reaches of the Yangtze River, the autumn grain harvest is a busy scene
.

Since the 18th National Congress of the Communist Party of China, China's grain and important agricultural products have been steadily supplied, and the foundation for ensuring national food security has become more and more solid
.
China's grain output has been stable at more than 1.
3 trillion jin for seven consecutive years, achieving basic self-sufficiency in grain and absolute security of
grain rations.

In the fields of a bountiful harvest, behind the joy of every harvest, it is inseparable from the model of long-term cultivation in the field of grain
.

Heroic model, shining coordinates of the Chinese nation; Meritorious honor inspires the spiritual motivation
to move forward.
"Father of hybrid rice", winner of the Order of the Republic Yuan Longping, "Father of Chinese wheat distant hybridization", wheat breeding expert Li Zhensheng, corn expert and "most beautiful striver" Li Denghai.
.
.
Meritorious models who have made outstanding contributions in the field of grain have written their theses on the earth and made important contributions
to firmly stabilizing China's rice bowl.

On September 29, 2019, on the eve of the 70th anniversary of the founding of the People's Republic of China, the party and the state awarded the "Order of the Republic"
to eight heroic models with the highest standard.
Yuan Longping, known as the "father of hybrid rice"
, is one of them.

Yuan Longping devoted his life to the research, application and promotion of hybrid rice technology, invented the "three-line method" indica hybrid rice, successfully developed the "two-line method" hybrid rice, created a super hybrid rice technology system, and made outstanding contributions
to China's food security, agricultural science development and world food supply.

In order to solve China's grain problem, for decades, the scientific research team led by Yuan Longping has successively solved problems, and the yield of super rice is 700 kg, 800 kg, 1000 kg, 1100 kg.
.
.
World records have been broken
again and again.

Yuan Longping often talked about two dreams before his death, one was the dream of riding under the grain, and the other was that hybrid rice covered the world
.
Today, China's rice production ranks first in the world, reaching 212.
8 million tons in 2021, of which more than half of the hybrid rice planting area is planted, and the cumulative planting area exceeds 600 million hectares; from the banks of the Mekong River in Vietnam, Sumatra in Indonesia, to the Indus Plain in Pakistan.
.
.
Hybrid rice has been popularized and introduced to dozens of countries and regions, with an overseas planting area of 7 million hectares
.

In the south of China, Yuan Longping improved rice, greatly increased the yield, and solved the problem of food and clothing for Chinese; In northern China, Li Zhensheng, known as the "father of China's wheat distant hybridization", devoted his life to wheat research, and once made the yield of wheat surpass rice
by cultivating wheat seeds.

In 1956, in the face of the crisis of the crazy spread of wheat stripe rust, which greatly reduced grain production, Li Zhensheng decided to cultivate disease-resistant seeds and improve the immunity of wheat against diseases
.
After more than 20 years of experimentation, failure and re-experimentation, he led the team to successfully breed a new series of wheat varieties
.

Li Zhensheng's unremitting efforts in scientific research finally brought earth-shaking changes to China's wheat cultivation - in 1980, the new disease-resistant Xiaokai series began to be promoted, planting 150 million mu, an increase of 6 billion kilograms
compared with the previous yield.
At the same time, other improved seeds of the Xiaokai series have also been successfully cultivated, with a total of 70 seeds, with a planting area of up to 300 million mu and an increase in yield of 7.
5 billion kilograms
.

In 2006, Li Zhensheng won the highest national science and technology award
.
Now, Li Zhensheng is still with wheat, leading the team to continue to study the topic of wheat production in
the saline-alkali land of Huanghuaihai.

Like Li Zhensheng, the "most beautiful struggler" Li Denghai is still on the front line
of corn breeding scientific research.

After years of deep cultivation in the corn breeding industry, Li Denghai has cultivated compact corn varieties with upward leaves, which are more resistant to dense planting and conducive to high yields
.
The seed industry scientific research team led by him has continuously refreshed corn yield: in 1989, the yield of summer sowing corn "Yedan No.
13" was 1096.
29 kg per acre, becoming the first compact corn hybrid in China with an acre yield of more than 1000 kg, and setting the world's first record
for high yield of summer corn.
Subsequently, it created China's first high yield record of more than 1100 kg per mu and 1239.
14 kg per mu; in 2013, "Denghai 618" was planted in Xinjiang, with an mu yield of 1511.
74 kg, becoming the first compact corn hybrid in China with a spring corn yield of more than 1500 kg per mu
.

At present, more than 120 new compact hybrid corn varieties bred by Li Denghai's team have passed the examination and approval of the state and provinces, and have been promoted in total 1.
3 billion mu
across the country.

In addition to Yuan Longping, Li Zhensheng, Li Denghai, there are also Zhou Wei, a scientist in the nutrient management post of the National Rice Industry Technology System and winner of the National May Day Labor Medal, Chen Wanquan, a researcher at the Institute of Plant Protection of the Chinese Academy of Agricultural Sciences and a winner of the National May Day Labor Medal, and Jin Liping, chief scientist of the National Potato Industry Technology System and winner of the title of National 38th Red Bannerman.

In the field of grain production, on the front line of agricultural science and technology research, a large number of meritorious models have made unswerving and selfless dedication to help the road of food security with Chinese characteristics move forward steadily
