On December 11, the National Bureau of Statistics released grain output data, and the national grain output reached a new highSo, who are the "food families"?Do you know what you eat all year round?Learn in one article
What crops count as "food"?
As the saying goes: the south is the meter, the north side.
Beans and potatoes are also common staple food supplements.
Then we are talking about food crops.
What do you mean?
China's food crops.
It mainly includes cereals, legumes, and potatoes.
Cereals. Mainly rice, wheat, corn, others include millet, sorghum, barley, oats, buckwheat, etc.
Legume. Including soybeans, mung beans, red beans, other miscellaneous beans, etc.
Potato. Including potatoes, sweet potatoes, etc.
Follow the harvest season.
Food crops can also be divided into:
Early rice, summer grain, autumn grain.
What do early rice, summer grain, and autumn grain refer to?
In 2023, the national summer grain output will be 2923000 million catties, a decrease of 25 over the previous year000 million catties, down 08%。
In 2023, the national early rice production will be 566700 million catties, an increase of 4 over the previous year300 million catties, an increase of 08%。
In 2023, the national autumn grain output will be 10,418400 million catties, an increase of 198 over the previous year400 million catties, an increase of 19%。
Among them, the rice yield was 4132100 million catties, a decrease of 37 over the previous year800 million catties, down 09%；
Wheat yield 2731800 million catties, a decrease of 22 over the previous year700 million catties, down 08%；
Corn yield 5776800 million catties, an increase of 232 over the previous year800 million catties, an increase of 42%；
The production of beans was 476800 million catties, an increase of 6 over the previous year600 million catties, an increase of 14%；
Soybean production 416800 million catties, an increase of 11 over the previous year200 million catties, an increase of 28%；
The output of potatoes was 602800 million catties, an increase of 7 over the previous year300 million catties, an increase of 12%；
Corn has become a well-deserved "champion of yield increase" of the "grain family" this year!
And what promotes the continuous increase in the production of these food crops has to be the black technology in those fields!
The "science and technology fan" in the farmland
1 Soybean and corn strip compound planting.
2023 will be a large-scale promotion in China.
The second year of soybean-corn strip multicropping.
Soybean-corn intercropping.
It is not new to the Chinese.
However, due to the inconsistent growth height of corn and soybeans.
The operation is complex and the planting efficiency is low.
This practice is gradually falling out of use.
Yang Wenyu, a professor at Sichuan Agricultural University.
He is the chief scientist of soybean and corn strip composite technology.
He and his team have been researching for 23 years.
Successfully made corn and soybean two crops.
Harmonious coexistence in the same farmland.
Let this pair of "** partners" complement each other's advantages.
It not only alleviates the problem of soybean and corn grabbing land.
Soybean production has also increased.
2. Air-ground integrated intelligent perception system.
Of course, those who bear the favor of "black technology".
It's not just soybeans and corn.
In Heilongjiang, which only produces one crop of rice a year.
Technology is changing the traditional way rice is grown here.
Satellite remote sensing, UAV near-earth space remote sensing
Ground intelligent monitoring equipment.
Form an intelligent perception system that integrates the sky and the ground.
Accurately monitor every inch of land and every seedling.
At the same time, every piece of data captured by the device.
will be uploaded to the cloud platform.
Through the simulation of the "smart brain".
Provide big data analysis and planting solutions for agricultural production.
3 The "watering general" in the field
More than just monitoring aids.
More and more high-tech technologies are being developed by China.
Have learned to manage themselves.
A drone in the sky flies with a spectral camera.
Irrigation is carried out by a large self-propelled sprinkler underground.
The spectral camera flies over the crops.
You can know how much water to water and how much fertilizer to apply.
Like a "general".
Automatically generate a "battle plan".
And the large self-propelled irrigation machine underground.
It's like a "smart creep".
After receiving the "battle plan", he began to water.
Intelligent operation throughout the process.
Free the hands of the peasant uncle.
Grain production is at a record high every year.
Behind the condensed is.
The brainchild of Uncle Farmer and countless scientific researchers.
A bite of your meal.
Probably the result of their countless all-nighters.
Learned this.
Don't waste food on the table in the future
